In addition, I determine Todd's request for the appointment of a Lay Member to sit with me at the substantive hearing which is set down for a six-week fixture due to commence on 15 February 2010. [2] In a judgment delivered on 25 July 2008, I determined an earlier series of interlocutory applications. In the proceedings, Todd pursues some 10 causes of action challenging the conduct of its co-joint venturers in the Pohokura Joint Venture. Their relationship is governed by the Pohokura Joint Venture Operating Agreement (PJVA) concluded in 1999. In approximate terms, Shell has a 48% interest and OMV and Todd 26% each. For some years, the parties evolved proposals as to the terms on which the Pohokura Field might be exploited, including a proposal that the three joint venturers would jointly market the output from the field. They sought and were granted consent from the Commerce Commission on certain terms to do that. The financial commitment to develop the field was made by all of them in 2004. [3] Todd's causes of action seek: · declarations as to the interpretation of relevant provisions in the PJVA; · allegations of breach of that agreement; and · various causes of action alleging that the conduct of Shell and OMV in relation to exploitation of the field is contrary to numerous provisions of the Commerce Act 1986. [4] It is in this context that the following applications have been argued. First application: To set aside Shell's claims to confidentiality for certain discovered documents [5] Counsel advised that the volume of Shell's discovery in the proceedings extends to some 75 Eastlight files, of which it has claimed confidentiality for some 15 Eastlight files. Thus far, inspection of those documents has been restricted to Todd's external legal advisers and appropriate experts retained by them in relation to the case, with all such personnel only getting access to Shell's confidential documents after completing appropriate confidentiality acknowledgements. Todd's solicitors wish to disclose Shell's confidential documents to Todd executives who are providing them with instructions on the case. [6] Mr Murray Jackson, Manager, Contract Support, for Shell has analysed its confidential documents as falling within the following categories: (a) Shell's gas sales contracts; (b) internal commercial and strategic planning for gas marketing; (c) terms and conditions for the sale of gas (including price and volumes, Shell's commercial aspirations for such terms, and current terms and commitments under existing contracts); (d) internal documents prepared for the purposes of engagement with the PJV parties (or either of them); (e) internal documents prepared for the purposes of entering into negotiations with the PJV parties (or either of them) on commercial issues such as: (i) joint sales and marketing; (ii) the terms of a JV uplift agreement; (iii) gas balancing; (f) Shell Group Budget Proposals, Group Investment Proposals and similar Shell Group internal documents containing budgeting and strategic information prepared at various stages of the project for the procurement of capital expenditure or other investment in the Pohokura project; (g) confidential submissions made to the Commerce Commission as part of its processes. [7] There was no dispute as to the accuracy of this summary. [8] Illustrative of the concerns created for Todd's legal advisers is the inability to take instructions directly from Todd executives on references in the Shell confidential documents to the evolving status of 70 petajoules (PJ) of gas per annum as the capacity of, or rate of output from, the Pohokura Field. At the core of the proceedings is Todd's challenge to the use by Shell and OMV of their majority votes to effectively settle 70 PJ as the rate of extraction of gas in the off-take regime governing management of the venture. Todd's claims raise various challenges to this, given Todd's aspiration to have the capacity to take its proportionate share of more than that volume of gas per annum. [9] It appears that Shell's case will be that, in various forms, 70 PJ per annum was the level of extraction recognised by all three joint venturers from the early days of proposed development of the field. [10] For its part, Todd wishes to analyse the minutiae of how the figure of 70 PJ per annum got whatever status it does have and, as importantly, the purposes motivating Shell in opting for that volume. Todd seeks to establish that Shell's view on the rate of extraction from Pohokura was for purposes other than the optimum extraction of this field. For these and other reasons, Mr Olney complains that the preparation of Todd's case is prejudiced if senior Todd executives who were involved at the time are not able to consider the various Shell papers, and provide a "first hand" reaction to what Todd perceived the position to be at the relevant times. Mr Olney suggests that the presently available alternative procedure of inviting the relevant Todd executives to respond to open questions as to the state of affairs discerned by an analysis of Shell's papers undertaken by Todd's counsel and independent experts is unduly cumbersome and risks missing points that may be of importance. [11] Mr Olney contends that that form of prejudice substantially outweighs any residual risk to Shell's commercial interests, by disclosure of papers that he to characterises as now all being historic and having no, or an insignificant extent of, current commercial sensitivity. For instance, Shell proposals as to the terms on which it would offer a first tranche of gas from the Pohokura Field, and strategic considerations for Shell arising from the inter-relationship between the extent of the Pohokura resource and Shell's interest in other fields such as Maui, was now spent because all such contracts have been concluded. Todd argued that the state of the market has moved on so that those considerations could not be treated by Todd as necessarily applying to Shell's commercial tactics, for example in respect of subsequent contracting for sales of later tranches of Pohokura gas. [12] For Shell, Mr Taylor's response focused on three aspects. First, the substantial extent of ongoing commercial sensitivity surrounding the documents for which confidentiality is maintained, notwithstanding their age. His second point in support of the first was to invite comparison with the character of documents for which Todd has claimed confidentiality, and which claim Shell continues to respect as appropriate. The third point was that Todd cannot demonstrate any substantial extent of prejudice arising from its having to prepare its case by the somewhat more cumbersome method of testing the circumstances in which the position of the respective parties evolved over the relevant period by questioning of the executives on open terms. This is necessarily without disclosing any detail of what Shell was doing by explicit reference to the content of its confidential documents. Ongoing sensitivity [13] In terms of the ongoing sensitivity, Mr Taylor was insistent that documents from the very beginning of the period in issue retain current and ongoing sensitivity of vital importance to Shell. One feature of the intensely competitive relationship between Shell and Todd relates to opportunities that could arise for one, when appraised of the detail of a weakness in the market position of the other. A pre- occupation for Shell reflected in many of the confidential documents is the steps it might take to minimise exposure or provide complete cover for a deficiency in supply relative to commitments to deliver over a particular period, when viewing its total gas supply business. Mr Taylor acknowledged that Todd would know in general terms about the parameters of such a potential problem for Shell, but that disclosure of the content of the confidential documents would give Todd a sufficiently precise indication of Shell's perception of the prospective problem for it to be "gold" in competitive marketing terms. Although details on this particular matter were perhaps the most intense concern, Mr Taylor instanced a number of other matters of Shell's ongoing tactics and strategic thinking that may well have been reflected in the documents. For instance, those dealing with the terms on which gas would be offered to potential buyers from the first tranche retain considerable value to a competitor because of the safe assumption that they would also influence Shell's conduct in later rounds of negotiations. Comparison with documents for which Todd claims confidentiality [14] As to the second of the points taken for Shell, Mr Taylor handed up a small volume of Todd's documents that have been inspected on the same restricted basis as the terms imposed by Shell for its confidential documents. Mr Taylor drew substantial support for his primary argument by inviting me to consider the other side of the coin represented by these documents. These examples of Todd's documents reflected the quite acute dynamic as between Shell and Todd in their respective options for flexibility in the volume of supply of gas from Taranaki hydrocarbon resources. The evolution of Todd's strategy as instanced in these documents suggested a priority of sequence of exploitation that best suited Todd's long-term optimisation of value from its investments. Whilst Shell might make well- educated guesses about those strategic priorities, Mr Taylor pointed out that it would be invaluable for Shell to know the nature of Todd's thinking with the level of certainty that would ensue from Shell executives having access to these confidential Todd documents. [15] Counsel accepted that I can only evaluate the terms on which confidentiality is preserved as a matter of impression, rather than a finite finding of the extent of harm that would flow from disclosure. At that impressionistic level, I am well satisfied that, notwithstanding the volume of them and the age of some of them, Shell is entitled to be concerned to preserve confidentiality of the documents for which it has been claimed. [16] Part of Mr Olney's criticism of Shell's defence of its position is that Shell bears an onus, on a document by document basis, to make out the extent of prejudice that would flow. He submitted that Shell's evidence did not discharge that onus. As a matter of first principles, discovered documents are to be available for inspection by the opposing parties and constraints on the usual process constitute an exception, the extent of which has to be justified by the party seeking that exception. Such has been the consistent approach since at least Commerce Commission v Port Nelson Ltd HC NEL CP12/92 2 June 1995 McGechan J and Professor Lattimore; Port Nelson Ltd v Commerce Commission [1996] 3 NZLR 554 (CA). I accordingly accept Mr Olney's proposition that there is an onus on Shell to make out the requirements for confidentiality. [17] Shell has addressed that point in the affidavit from Mr Jackson. Mr Jackson deposes to having reconsidered all of the documents for which Shell has claimed confidentiality in its list of documents. In addition to being able to categorise the documents as cited in paragraph [6] above, this analysis has enabled him to identify some documents that, on reconsideration, Shell is prepared to transfer into the "open" section with the consequence that there can be full inspection of them on the usual basis. Mr Jackson also identified some documents which contained relatively confined passages of confidential information and which he has recommended to Shell's solicitors be made available for inspection on an open basis, subject to those passages being redacted. He has also reconsidered the documents in terms of relevance and found some documents that he now considers were included as potentially relevant when they should not have been, and were therefore included in the list by error. [18] I consider that Mr Jackson's analysis of the documents, demonstrated by his re-classification of a number of them and the division of the rest into the seven categories quoted in [6] above, demonstrates a sufficiently individualised analysis, relative to the substantial volume of documents being dealt with here to discharge the onus of establishing a very real concern to protect their confidentiality. [19] I took it to be common ground between counsel that there is a pattern, reflective of the nature of the organisations involved, of Shell writing down a great deal more of these sorts of strategic analyses, than has occurred at Todd. That provides one explanation for the disparity in volume of documents (i.e. some 15 Eastlight files of confidential information sought to be protected for Shell, in comparison with one Eastlight file for Todd). [20] I am also satisfied that this is not the sort of confidential information that could be "mentally ring-fenced" and not misused in contexts outside of the present litigation. The value to each party in retaining confidentiality of their respective documents is because of the strategic value it has. Its value is pervasive in the ongoing dealings and in their competition in the market. [21] Mr Taylor was not prepared to contemplate that Todd executives could compartmentalise the use they made of such information once in possession of it. He went further and submitted that Shell should not be expected to trust Todd at all, given an instance of Todd abusing the implied undertaking to constrain the use of inspected documents solely to the proceedings in which they have been discovered. A material document discovered in these proceedings, the Alignment Agreement between Shell and OMV, has been referred to in an affidavit from Todd's Managing Director, Mr Tweedie, in entirely unrelated proceedings. Mr Jackson's affidavit described correspondence between solicitors for OMV and those acting for Todd on misuse of that document. Mr Jackson believed that OMV's solicitors had not had any satisfactory explanation. I called for the correspondence relating to this apparent unauthorised use of a document obtained on discovery, and have considered it. I have also considered Memoranda on this criticism, respectively from Mr Olney dated 31 July 2009, from Mr Taylor dated 5 August 2009, and in reply from Mr Olney dated 11 August 2009. [22] Mr Olney's 31 July 2009 Memorandum explains that another principal of Russell McVeagh was acting for Todd in the unrelated litigation, and had the Alignment Agreement drawn to his attention by Mr Tweedie. Mr Olney advises that his firm provided advice to Todd that it was permissible to refer to the existence of the Alignment Agreement in Mr Tweedie's affidavit in those unrelated proceedings, but that it was not permissible to produce that document as an exhibit. On the basis that Mr Tweedie made reference to the agreement on the basis of legal advice, Mr Olney now invites the Court to exonerate Todd from any responsibility for breach of the implied undertaking. [23] His firm's advice was plainly wrong, on the basis of well-settled authority. I am not satisfied there is any adequate explanation for the breach of the implied undertaking. Nor would I be prepared to exonerate Todd on the ground that it breached the implied undertaking on the basis of legal advice. Todd's mining interests, and Mr Tweedie in particular, are seasoned litigants. I do not accept that Mr Tweedie is not cognisant of the extent of the implied undertaking, and the reason for it. As frequent litigants, Todd's mining interests no doubt have to rely on compliance by opposing parties with the implied undertaking when they give discovery of documents in the course of their various involvements in commercial litigation. The expectation of compliance has to be reciprocal. [24] Respect for the letter and spirit of rules governing access to a competitor's documents in the course of litigation is absolutely critical to the orderly working of the High Court Rules and to the conduct of all civil litigation in the Courts. A breach of this important undertaking is to be taken seriously, and deserves strong censure. However, punishment for such breach of the Rules should not arise in a tangential or unconnected context. Were relaxation or removal of the confidentiality constraint Shell seeks to maintain otherwise appropriate, I would not have been prepared to "punish" Todd by denying it wider access to the confidential documents on account of this breach of the implied undertaking. It does, however, afford ample grounds for Shell's submission that it ought not to be required to trust Todd executives to implicitly respect the letter and spirit of the High Court Rules governing access to, and use of, discovered documents. No substantial prejudice to Todd [25] The last aspect of Mr Taylor's argument for Shell was that Todd had not established any sufficient degree of prejudice in the preparation of its case. I agree with that submission. I tested Mr Olney as to the processes for taking instructions from Todd executives without making Shell's confidential documents available to them. Although I accept that it involves more work and is more cumbersome, I am not persuaded that Todd's case is likely to be materially weakened by Todd's advisers missing a point that might otherwise have been elucidated from a first-hand analysis of Shell's confidential documents by Todd executives. [26] In the end, there has to be a balance struck. Here, vigorously contested litigation has arisen in the course of an ongoing significant joint venture for exploitation of gas and condensate. The litigation has to be kept in perspective and should not be managed in a way that jeopardises the future of that significant venture. In short, the price for Todd is that it must run its case with whatever modest impediment eventually follows from Todd executives being kept away from the content of Shell's confidential documents. [27] Accordingly, Todd's present application is dismissed. I raised with counsel the need for a protocol in respect of any documents for which confidentiality is claimed by any of the parties, and which may need to be adduced in evidence and referred to in briefs of evidence. I anticipate counsel will be able to agree a protocol for redacted versions of briefs of evidence making reference to confidential documents being provided for the respective executives who are to be excluded from access to such documents. Cross-examination on such documents will probably require the Court to be cleared of those who have not completed confidentiality undertakings. Second application: For particular discovery from Shell of further details on supply/demand model [28] Shell has previously provided hard copy documents reflecting the computer analysis produced by a supply/demand model used in April 2005 as an aid to assessing the effects of different levels of production from Pohokura. More recently, an electronic copy of that model has also been provided. This application by Todd sought from Shell any further hard copy representations, or comments on, or electronic records reflecting, further use of that model. In particular, Todd seeks hard copy or electronic records reflecting the input into the model of any levels of production other than 70 PJ per annum. [29] The request relied upon two 12 April 2005 emails between Shell personnel. The first email set out 84 PJ per annum as Pohokura's processing facility, 70 PJ as its "planned sales gas plateau" and 60 PJ as the minimum rate as at 30 June 2006 stipulated in a Commerce Commission condition of its approval for joint marketing by the three joint venturers of the gas from Pohokura. In commenting on those statistics, Mr Mulvena of Shell had commented to others in a separate email: See Pohokura rates below from STOS. This was always going to be an interesting issue! Assuming a sales plateau below the plant capacity makes it essential we have a balancing arrangement in place as someone will always want to push sales up to plant capacity!! We have only assumed 70 Pj/a offtake so far in supply/demand study 83 Pj/a will take even more production/sales off Maui. [30] Todd retained a Wellington economist, Mr Kieran Murray, to provide expert evidence in these proceedings. Mr Murray has expressed the view in an affidavit in support of this application, having analysed the documents thus far inspected, that he would expect Shell to have modelled one or more scenarios with Pohokura producing more than 70 PJ of gas per annum using the model it had available for that purpose. [31] For Shell, Mr Mulvena has completed an affidavit which denies that, in light of the discrete purposes for which Shell was using the electronic model in its wider business, there could be any relevance to the use of the model for testing the consequences of any other level of production from Pohokura. In submissions, Mr Taylor advanced the arguments on lack of relevance by pointing out that the model, having been used in April 2005, would then be available for the year until April 2006 by which time the joint venturers had (by the majority votes of Shell and OMV) resolved the off-take regime for Pohokura at 70 PJ per annum. However, on Mr Taylor's analysis, in that year Shell had already committed itself to sales on the basis of production at 70 PJ and the focus was on completing the arrangements for Shell's dealings in its portion of production at that level. There was therefore no purpose relevant to the Pohokura joint venture for Shell to be exploring the wider consequences of promoting production from Pohokura at any different level from 70 PJ. [32] Mr Taylor also argued that if there were any other hard copy documents that made any form of reference to levels of production at Pohokura, they would already have been identified and discovered. Accordingly, Todd's current request for particular discovery could only relate to electronic workings, of which no hard copy record had been made. A number of Shell personnel are no longer with the company and a number are now outside New Zealand. A substantial extent of work would be involved in attempting to ascertain whether any of these Shell personnel had used the model to test the effects of a level of production other than 70 PJ. This was being requested on the basis of a speculative assumption made by Todd that Shell had a reason to undertake modelling on alternative levels of production and therefore would have done so. Mr Taylor protested that requiring this exercise to be undertaken was unjustifiably oppressive because the outcome would, in any event, be irrelevant. [33] I took Mr Olney to accept that Todd did not have grounds for contesting Shell's response that there were no more hard copy documents within the category contemplated, so that the request was confined to any electronic record of the model having been used for levels of production other than 70 PJ per annum. [34] Todd did not advance any conventional grounds for a belief that other records of the type sought are in existence. Rather, the application was based on the theoretical assumption that an organisation of Shell's type, having access to an electronic model of the type already discovered, would have used it to test the consequences of other levels of production. I am not satisfied that that theoretical construct is sufficient to warrant an order for further discovery. Todd has not established the existence of such electronic records, which is the initial premise that an applicant for such an order must make out, before the Court will exercise the jurisdiction to order further discovery. [35] Mr Olney acknowledged the cross-over between this request for production of further documents, and an interrogatory addressing the question of whether such other scenarios were tested by Shell. I need to return to the issue of relevance of any electronic workings, and whether the enquiries required to answer an interrogatory are oppressive in that context. [36] However, at this stage, Todd has not made out the case for an order for further discovery and this second application accordingly is dismissed. Third application: For further and better discovery from Shell [37] In its third application, Todd sought discovery of: · certain GSA1 and GSA2 contracts in relation to sale of Maui gas, plus documents in connection with those contracts; · five attachments referred to in discovered documents but not themselves discovered; · unredacted versions of certain STOS documents for which Shell has claimed privilege; and · a group of documents in which Shell has claimed common interest privilege. GSA1 and GSA2 contracts [38] My recollection is that Shell and Contact Energy have inherited the contractual positions under those contracts of Fletcher Challenge Energy and ECNZ respectively. The contracts provide for sale and purchase of Maui gas. Todd attributes relevance to those, because it seeks to argue that Shell's part in imposing 70 PJ per annum as the level of production at Pohokura has been influenced by Shell's own commercial considerations, irrelevant to the pursuit of optimum return for the Pohokura Joint Venture. Those other commercial interests of Shell include the profile of its sales of gas from its entitlement at the Maui Field. [39] I understand from counsel that the term of GSA1 has expired, but there are inter-relationships between that and GSA2, which is still current. [40] Although Mr Taylor did not have explicit instructions, in the course of argument he conceded the case for Todd to have access to the terms of both contracts, in their current and any superseded forms, subject to inspection being constrained by the confidentiality obligations thus far imposed for other confidential Shell documents. Mr Taylor has volunteered the documents on behalf of Shell, (subject to his instructions confirming this indication), without any acknowledgement of their relevance, but to avoid further argument. Accordingly, no order is needed on that aspect of this Todd application. [41] Todd also sought documents in Shell's possession that bore on the terms and operation of GSA1 and GSA2. Mr Olney argued that such documents might reflect Shell's strategic thinking in the overall management of its gas reserves, thereby throwing further light on the motives that Todd seeks to attribute to Shell, in stipulating 70 PJ as the level of production from Pohokura. [42] Mr Olney sought these surrounding documents within the period from 2002 from 2005 and claimed they were relevant because Shell's ongoing considerations in that period as to its Maui commitments obviously impacted on the view Shell took in respect of Pohokura. He invited the inference, from certain of the Shell internal documents annexed to the affidavits filed on these applications, that in the 2002- 2005 period Shell's analysis demonstrated an inter-play between its core supply from Maui, its possible additional quantities from Maui by virtue of "right of first refusal"(ROFR) gas, and the extent of production possible from Pohokura. [43] Mr Taylor resisted discovery of any additional documents within these types, on the basis that they could not possibly be relevant to any of the issues in the present proceedings, and that the obligation imposed on Shell to search for and list such documents would be oppressive. [44] On the impressionistic basis that is inevitable when dealing with an interlocutory raising matters of such detail in a case on such a scale, I am not persuaded that the peripheral documents commenting on GSA1 and GSA2 can claim sufficient relevance to warrant an order for their discovery. This is, of course, to the extent that they have not already been identified because of content that touches upon Pohokura. I am influenced in this by the additional burden that would now impose on Shell in searching for and listing such documents. The inter-relationship between how much gas Shell could procure from Pohokura, relative to the management of its sale contracts that depended on gas from other sources, seems likely to be made out. How that impacts on Shell's rights and obligations as alleged by Todd is another matter. Commentary on the terms of contract that Shell inherited appears to be beyond the reasonable circumference of relevance, given the scale of this dispute. "Missing attachments" [45] Todd sought discovery of five attachments referred to in email chains between Shell and STOS personnel. The attachments are detailed in paragraph 3(a) to (e) of Todd's application dated 8 July 2009. For the most part, Shell objected to discovering these documents on the ground that they are irrelevant to the issues in the proceedings. Shell relied on the decision in ANZ National Bank Ltd v Commissioner of Inland Revenue (2008) 18 PRNZ 916 (HC) for the proposition that reference to a document in a discovered document does not render the undiscovered document presumptively relevant. [46] Paragraph 3(a): The first attachment was a Word document attached to a 23 June 2003 email which itself was given the discovery number Shell_OCM_15.3. Without conceding relevance, Shell has agreed to produce that attachment on a confidential basis. [47] Paragraphs 3(b) and (c): The next two attachments sought were Excel spreadsheets attached to emails dated 8 March 2004 and 22 June 2004. From the context of the intra-Shell personnel emails to which they were attached (Shell discovered documents Conf_OCM_15.22.2 and 15.28.4), both spreadsheets addressed the extent of Maui ROFR gas. There is no direct reference to Pohokura in the relevant emails, and the earlier of them suggests that the spreadsheet was not particularly thoroughly prepared because it referred to asking STOS to "come up with something more robust...". [48] On Todd's theory of its case, Shell was evaluating optimum production from Pohokura for its own purposes, as an aspect of larger planning that involved all of Shell's other hydrocarbon resources. Todd contends that Shell's ability to expand and contract the total volume of gas it dealt with at any time by use of Maui ROFR gas is likely to give insight into the non-Pohokura considerations influencing Shell's decisions on the volume of production it sought from Pohokura. [49] Mr Taylor responds that this hypothesis is simply too remote, and that there is no reason for Todd to believe that the undiscovered attachments would have any relevance to such an analysis. [50] Again, deciding between these competing positions can only be impressionistic in the absence of considering the attachments themselves, which I do not propose to do in relation to these particular documents. [51] For the purposes of the present discovery application, I am prepared to accept that Todd brings the attachments within the outer boundaries of the test for relevance and is accordingly entitled to discovery of them. I anticipate that Shell will require inspection of them to be on the terms as to confidentiality that have been enforced in relation to other documents. [52] Paragraph 3(d): The next attachments sought are those referred to in a Shell internal email of 13 May 2004 (Shell Conf_AB_18.A.53.4). The text of the emails suggests that the attachments contain suggested changes to GSA1 and GSA2. Consistently with my determination on the documents commenting on the content of those contracts, I rule that they are not relevant and therefore do not need to be discovered. [53] Paragraph 3(e): The last of the attached documents are a Contact Energy press release and a Commerce Commission letter, referred to in an email of 25 March 2003 (Shell Conf OCM 23.1). The reference to the press release is immediately followed by the comment: The spotlight again turns on Pohokura development, the gas industry structure and by implication the Shell/Todd/STOS relationship and its competition impacts. [54] The email also refers to a Commerce Commission inquiry on Shell's change of stance in relation to an application to the Commission for approval to jointly market Pohokura gas. [55] I do not consider that Shell's discovery obligations should extend to producing an electronic copy of a Contact Energy press release. Todd's resources should be sufficient to identify and obtain that, should they consider it of any relevance. [56] Because of the connection between the subject of the Commerce Commission communication and the marketing of Pohokura gas, I am persuaded that the letter from the Commerce Commission may be relevant and is accordingly discoverable. Again, I anticipate that Shell would wish to afford inspection of it only on a confidential basis. [57] In summary, as to the attachments, that sought in paragraph 3(a) of Todd's application dated 8 July 2009 has been volunteered on behalf of Shell, subject to confidentiality. Todd has made out relevance, and is accordingly entitled to discovery, of the attachments sought in paragraph 3(b), (c) and the second of the attachments in 3(e). I am not satisfied as to the relevance of the attachments sought in paragraph 3(d), and the first of the attachments in paragraph 3(e) of the application. STOS documents [58] Shell has claimed privilege for certain communications between Shell in- house counsel and certain personnel at STOS. At the relevant time, STOS was resourced by personnel on secondment from Shell. Mr Taylor suggests that the Shell personnel were seconded on terms retaining certain Shell responsibilities as part of their on-going work. [59] However, Todd challenges the entitlement for Shell to claim legal professional privilege when an in-house counsel at Shell (whose only client can be Shell itself) communicates with somebody at STOS who is, by definition, not within his client's organisation. [60] During the hearing, it was resolved that I should see the three documents which have been partly redacted on the basis of privilege claimed in these circumstances. I issued a Minute on 24 July 2009 to record the arrangements that would pertain to these documents. Since, without objection from Todd, solicitors for Shell invited me to expand the range of identities of personnel involved in these communications, I set out the Minute in the amended form after hearing counsel further on it: [1] In the course of argument on Todd's application for access to inspect certain STOS documents, an issue arose as to the entitlement of Shell to claim solicitor/client privilege for such documents on the basis that they were communications between Shell in-house counsel, Shell employees and a person or persons having a STOS email address, being Shell personnel on secondment to STOS and/or persons engaged or employed by STOS believed at the relevant time to be providing services to a member of the Shell group of companies. [2] Counsel are agreed that in respect of this aspect of Todd's application, I should inspect the documents in an unredacted form to assess the entitlement of Shell to claim privilege for them on the basis it has advanced. I have directed that that aspect of Todd's application will be treated as standing adjourned, against the contingency that, having inspected the documents, I consider it is appropriate to call for further argument on the matter. [61] I have now considered the three documents in unredacted form. As to the first of them (Shell VO_4.2), this is an email from Alan Bewley, in-house counsel at Shell, to various recipients involved in a preceding chain of emails. The recipients include a Mr Phil Moore whose email address is a STOS one. The redacted content of Mr Bewley's email does not provide the legal opinion that preceding emails in the chain contemplate, but rather predicts what such an opinion is likely to advise. Legal professional privilege is inarguably appropriate to the extent that it was a communication between Mr Bewley and other Shell employees. I accept that those involved in the series of emails at the time were entitled to treat personnel on secondment at STOS as within the Shell umbrella, for the purposes of sharing with them strategic and, in this case, legal communications. From the content of Mr Bewley's contribution and the context in which it appears at the end of the email chain, I can readily infer that if Mr Bewley thought he would be waiving legal professional privilege by including Mr Moore within the recipients, then Mr Moore simply would not have got it. In that sense, any waiver of privilege would be entirely inadvertent. [62] More positively, I am satisfied as a matter of clear inference that Mr Moore is included because, notwithstanding his position at STOS, he retained responsibilities for Shell, to the extent that any distinction might be required between work he was doing for STOS, and his residual contribution to progressing Shell's interests. [63] I accordingly uphold the claim to privilege in that document. [64] In relation both to that first document, and to the next one I am about to consider, Mr Whalley's affidavit in support of Shell's claim to uphold the privilege contends that the redacted aspects are in any event irrelevant. Given the scale of discovery and the breadth of relevance claimed by Todd, I would prefer not to make a fine judgment approving the exclusion of the document on relevance and am satisfied that is unnecessary, given the entitlement of Shell to maintain privilege in it. [65] The second group of emails where challenged redactions have been made (Shell_ABE_17.589, 23, 24 June 2004) starts with a concern raised by Mr Selvadurai on behalf of Todd about a proposed procedure for the operator (STOS) to obtain approval to certain categories of expenditure for the project. In addition to addressees I assume to be other Todd personnel, it was addressed to Dennis Washer at Shell, and Phil Moore at STOS. The first redacted email is Mr Washer forwarding Mr Selvadurai's email to the in-house counsel, Mr Bewley, seeking advice on the contractual point that had been raised. Some four minutes after doing that, Mr Washer has copied both the original email and his request to Mr Bewley on to Mr Moore and a further recipient, Warwick Smith, with a STOS email address. The intent of the somewhat cryptic comment in forwarding on the two earlier emails, namely "Whoops...my apologies...all JV communications into the project to yourself" appears to be acknowledging that communications, implicitly within Shell, about its work on the joint venture ought, in any event, to have been copied to Messrs Moore and Smith, notwithstanding their email addresses at STOS. [66] Shell has then redacted the whole of two emails thereafter. The first is from Mr Moore to Mr Bewley, and the second is a reply from Mr Bewley to Mr Moore. The terms of the former communication make it abundantly clear that Mr Moore considered he was entitled to ask Mr Bewley for legal advice that reflected Shell's position within the venture on terms that Mr Moore would use to protect and advance Shell's position, and which he did not need to disclose to other joint venture interests. Mr Bewley's response implicitly shares that understanding as to the nature of the communication between them. [67] Accordingly, by application of the reasoning used in relation to the first redacted document, I am also satisfied that Shell is entitled to claim privilege for this second series of emails. [68] The third document partly redacted on this basis is a chain of emails sent on 4 and 5 July 2006 (Shell RMA.40.240). It begins with a request on behalf of Todd in relation to "Pohokura communications". It is addressed to Mr Moore at what appears at the time to be a Shell email address. Mr Moore's reaction is to forward the Todd email to three Shell addressees and a Mr Schmitz at a STOS email address. The Shell recipients included in-house counsel, Chris Street, and the senior executive, Murray Jackson. The next contributor to the chain is Mr Jackson, and it is his email that has been redacted by Shell in its totality. Mr Jackson comments on his perception of Todd's conduct, and then recommends that two separate actions be considered. His email concludes with the direction that those steps would need to be reviewed by Lawrie Hinton, whom I infer at the time was a Shell in-house counsel. He is among the recipients of Mr Jackson's email. [69] All of what follows has been disclosed. It appears to end with the whole chain of emails being referred to Robert McDonald, whom again I infer was a Shell in-house counsel at the time. [70] The respective roles of Mr Schmitz and a Mr Coomber, who were the recipients of the Jackson email with STOS email addresses, are not specified. However, from the content of the whole string of emails and their inclusion in it, it is apparent that they are being included because they have some responsibility to advance Shell's interests within the operator. I consider that the details of Mr Jackson's two proposed actions are entitled to legal professional privilege because he is initiating steps that he contemplates will be the subject of legal advice, and intending that Shell's response to Todd would be taken with the benefit of such advice. However, the particular addressee, and the opening comments, do not bear on the subsequent proposals on which he contemplates legal advice will be taken. Accordingly, I order that the redaction in this chain of emails is to be reduced so as to make available for inspection by Todd the header of Mr Jackson's email despatched on 4 July 2006 at 7.08pm, and the content of that email down to and including the line "I see two separate actions", together with the salutation at the end and Mr Jackson's name. Common interest privilege [71] Shell has claimed legal professional privilege, on the basis that a common interest privilege arises, in respect of the following four categories of documents: a) Confidential legal advice provided jointly to both Shell and OMV, the privilege in which belongs to Shell and OMV jointly, and over which Shell also claims legal advice privilege; b) Confidential legal advice provided to OMV, the privilege in which belongs to OMV and which is not Shell's to waive, which has been shared with Shell in circumstances where that privilege has not been waived; c) Confidential legal advice provided to Shell, the privilege in which belongs to Shell (and over which Shell claims legal advice privilege), which has been shared with OMV in circumstances where that privilege has not been waived; or d) Confidential communications between Shell and OMV's in-house counsel in relation to the legal advice obtained by either of them individually or both of them jointly. [72] In submissions for Shell, it proposed that this list ought to be expanded by a further category in the following terms: e) Communications with persons, including persons having a STOS email address, for confidential communications between Shell group in-house counsel, Shell employees and/or employees of the Shell group made available to STOS on secondment and/or persons engaged or employed by STOS believed at the relevant time to be providing services to a member of the Shell group pursuant to a Technical Services Agreement, in circumstances where the disclosure to STOS personnel is not considered inconsistent with a claim of confidentiality. [73] Todd conceded that categories (a) to (c) are properly the subject of a claim to privilege. However, it remains concerned that there ought to be a re-listing of documents claimed to come within those categories by Shell, to enable Todd to better assess the entitlement to claim privilege on these grounds. [74] Shell opposes any obligation to re-list as oppressive given the stage that the proceedings have reached, the extent to which the issues have been aired already, and the need for Shell's advisers to commit resources to other aspects of preparation for trial. [75] Having heard all the arguments I have, and gained some appreciation of the detailed analysis each set of advisers has been able to bring to bear on the case of the other side and its documents, I have decided that Todd's residual requirement for a more exhaustive listing of categories (a) to (c) is not warranted. [76] As to category (d), a first consideration is whether the entitlement to claim privilege is to be regulated by the provisions of the Evidence Act 2006, or the pre- existing common law position. The documents were all created before the Evidence Act came into force, and accordingly in an environment where those involved in them reasonably contemplated that the entitlement to withhold them from inspection in any litigation was regulated by the common law rules. [77] A different form of this issue arose in my earlier interlocutory judgment in these proceedings delivered on 25 July 2008 (see paragraphs [83] to [91]). Consistently with my conclusion on that occasion, I consider the present issue is to be resolved on the pre-Evidence Act state of the common law. [78] Todd's challenge to reliance on common interest privilege in respect of category (d) is that it seeks to assert privilege for original communications between personnel who are not in a solicitor/client relationship. Rather, the communications are between lawyers acting for different clients. [79] The rationale for the so-called "common interest privilege" is not in fact to recognise that privilege from disclosure should extend to a category of communication beyond that applying to solicitor/client communications. Rather, where the terms of an original (privileged) communication between a solicitor and client are then shared with a third party, be it another lawyer or another party, the privilege attaching to the original solicitor/client communication is not lost where it is passed on in the context of a relationship that the law recognises as giving rise to a common interest between the person forwarding the solicitor/client communication, and the person receiving it. [80] Original communications between lawyers for two different clients are not within this common interest privilege as it is customarily defined. Nor do they fall within the rationale recognised for what is in fact an extension of solicitor/client privilege. [81] In the course of argument, Mr Taylor was inclined to accept that, where the communication between, say, Shell's in-house counsel and OMV's in-house counsel was not to convey the effect of advice given to Shell, then it was not a communication covered by the scope of common interest privilege as recognised at common law. To the extent that the in-house counsel with each company were exchanging views with each other as to the advice each of them was likely to give to their respective employer/client, Mr Taylor invited me to treat it as reflecting advice that was "being given", and therefore covered by a common interest privilege. I do not accept that characterisation. The advice is to be conveyed to the client. Once it has that status, then its subsequent re-publication to a third party with the necessary common interest may be covered by that original privilege. [82] For Shell, Mr Taylor sought to invoke as an alternative that litigation privilege could, in any event, apply to the communications in question. Once litigation is seriously in contemplation, and the dominant purpose for creation of a document is to further the interests of a client in relation to that litigation, then far broader categories of communication are entitled to privilege on this different basis. If Shell were to make out that, at the relevant times, litigation privilege could be invoked, then it would apply to communications such as those between its own in- house counsel and those acting for OMV. It was agreed that I should consider the content of documents for which privilege is claimed on grounds (d) and (e). During the hearing, I was provided with an envelope containing some 13 such documents. [83] This matter was raised late and had not been traversed in the evidence filed in support of, and in opposition to, these interlocutory applications. Accordingly, I directed that Shell be given seven days to provide affidavit evidence as to when Shell could reasonably have apprehended that litigation was in contemplation. I have now received and considered an affidavit dated 31 July 2009 from Mr Robert Macdonald, an in-house solicitor with Shell. Mr Macdonald's view was that litigation was reasonably apprehended by Shell from November 2005. Alternatively, matters had developed to a point where litigation was very likely from March 2006. For Todd, Mr Olney informally conveyed a message to the Registry on 10 August 2009 that his client had nothing to add on the date from which Shell claimed litigation privilege. [84] I have assessed the 13 documents, relative to the potential grounds for Shell to now claim privilege for them. I determine as follows: a) Shell PC LLA 13.1. 10 March 2005 email from OMV in-house counsel to Shell in-house counsel. This reflects comments on the potential content of a Pohokura joint venturers' indemnity, reflecting the respective interests of OMV and Shell. It does not pass on to Shell the terms of internal legal advice provided by OMV's in-house counsel to OMV, and accordingly privilege cannot be maintained for it. b) PC_CS_41.12. 21 April 2006 emails among in-house counsel at OMV and Shell, proposing meetings on contractual terms and prospect for exchange of advice previously received by each company. It does not reflect a sharing of legal advice and accordingly is not entitled to privilege. c) PC_CS_41.5, 41.6, 41.7 and 41.8. This series of emails, all dated 3 July 2006, are to be assessed together. They reflect consideration of the terms of communications between Shell and OMV on the one hand, and Todd on the other, and in particular the implication for Court proceedings of the terms used. I am satisfied they are entitled to litigation privilege. d) Shell PC_CS_41.9 (enclosing 41.10). This 7 July 2006 email from Shell in-house counsel to OMV merely copies correspondence sent that day to Todd. It is not entitled to privilege. e) Shell PC_CS_41.11 10 July 2006 email. This is merely OMV's acknowledgement of the email at 41.9 and is similarly not entitled to privilege. f) Shell PC_CS_41.13. Notionally dated 31 July 2006, the exchanges between in-house counsel at OMV and Shell on that date relate to a request by OMV to reconstruct the terms of advice about contractual terms previously provided by in-house counsel at Shell to Shell in December 2005. This communication represents the subsequent sharing of a communication which in its original form was privileged. I am satisfied that in this particular context, by the end of July 2006 there was the requisite common interest established between Shell and OMV, and accordingly this document is entitled to common interest privilege. g) PC_CS_41.15 1 August 2006. Email from in-house counsel at OMV to in-house counsel at Shell, providing a copy of Shell's own earlier correspondence with Todd. No privilege can be claimed for this communication. h) PC_CS_41.18 15 August 2006. Email from in-house counsel at Shell to in-house counsel at OMV as to terms of a Memorandum for the Court in these proceedings. It is entitled to litigation privilege. i) Shell PC_RMA_40.11, .12, .13, .14. These February 2006 email exchanges between OMV and Shell relate to negotiation of agreements to which their entities were to be parties. There is no basis on which privilege can be claimed for them. j) PC_RMA_40.15, .16 - 9 March 2006. Email from Robert Macdonald at Shell to numerous addressees (including two at OMV) about work to be done on the drafting of numerous agreements subsequent to a meeting that day. Although the potential relevance of much of what is said is difficult to identify, as the document has been listed, it is discoverable and as OMV and Shell were distinct parties to those agreements, there is no basis for claiming privilege for the communication. Pre-contractual negotiations for the PJVA [85] Todd seeks discovery of any documents in the possession of Shell that it has inherited from the Fletcher Challenge entity that was an original party to the PJVA. [86] In respect of the equivalent position for OMV which inherited the position under the PJVA of the other original party to it, Preussag Energie GmbH, OMV responded to Todd's request by conducting a diligent search and confirming that there are no such documents. Todd accepts that position. [87] However, Shell has refused to undertake such a search on the basis that any documents, if they existed, could not be relevant and that it is oppressive to require it to undertake the search. I was advised that the form of agreement adapts a standard United States form for such joint ventures. There would be considerable risk in attributing anything to what the original parties thought about using that precedent. [88] Mr Olney relies on the approach to contractual interpretation as reflected in the Court of Appeal's decision in Boat Park Ltd v Hutchinson [1999] 2 NZLR 74, which recognises that all surrounding circumstances and the commercial context may be relevant in construing a contract. He also argues that lack of admissibility of a document does not exclude it from the scope of discovery: Comalco NZ Ltd v Broadcasting Standards Authority [1995] 3 NZLR 469 (HC), a point confirmed on appeal (1995) 9 PRNZ 153 (CA). [89] Inherent or potential unreliability of such further documents is probably to be seen in the same light as inadmissibility: it cannot deprive a particular category of documents of their potential relevance. However, the pre-contractual stance adopted by the parties to the agreement, neither of whom are now parties to the litigation or to the ongoing operation of the agreement, must be at or beyond the boundaries of any potential relevance to arguments about the interpretation of the agreement. The relative extent of oppression in requiring Shell to trawl through any records it inherited at the time of acquisition of Fletcher Challenge's energy interests should take into account the potential utility to the opposing party of requiring Shell personnel to undertake that task. The combined impact of very marginal prospect of any relevance, plus the latent, or at least potential, unreliability of such documents when measured against the scope of the task imposed on Shell, persuades me that it would be oppressive to require such further discovery to be undertaken by them. This aspect of Todd's application is declined. Fourth application: To administer interrogatories and require further particulars from Shell and OMV [90] Todd has sought answers to interrogatories served on both Shell and OMV, on the basis that the answers are necessary to enable it to adequately prepare its case. Mr Olney argued that the interrogatories go to questions of fact, and do not seek evidence. Todd relied upon the approach to interrogatories as reviewed in the decision in Bank of New Zealand v Gardner (1990) 2 PRNZ 278, a decision of then Master Hansen. That decision treats the rules on interrogatories to be applied in a way that brings to an end the "cards close to the chest" form of advocacy. Rather, interrogatories are to be used to assist the parties in coming to a recognition of the proper issues through which settlement of disputes is to be achieved. The decision in Bank of New Zealand adopted the observation from Shore v Thomas [1949] NZLR 690: It is not necessary that the answer should be conclusive on the questions at issue; it is enough that they should have some bearing on the question, and that they might have a tendency to establish, or form a step in establishing, the allegations made. (695) [91] The Bank of New Zealand decision also recognised that what may constitute oppressive interrogatories is a question of proportion in each case. Interrogatories will normally be disallowed where answering them would require a search or inquiry out of all proportion to the value of the question or, generally, where to answer would be burdensome. [92] Mr Olney complains that Todd is unsure as to what Shell and OMV's answer is to the allegations of breach of various provisions of the Commerce Act, and also more generally as to Todd's allegation of the purpose or effect of the off-take rules and nomination protocols that have been procured by Shell and OMV's use of their majority voting power. Interrogatories, as against Shell [93] Mr Taylor argues that there is no necessity for the interrogatories to be answered because Shell's evidence will address in detail how the optimal production level of 70 PJ per annum was initially developed, and how it has come to be relied upon. Mr Taylor drew an analogy with the decision in Ancare NZ Ltd v Novartis NZ Ltd (1997) 11 PRNZ 393 (HC) for the proposition that interrogatories will not qualify as "necessary" if the questions traverse matters that the Court can be satisfied will be provided in evidence. However, Mr Olney argued that Todd has no way of knowing whether in fact the questions raised by its interrogatories will indeed be answered in Shell's evidence. [94] Perhaps more relevant as a point of distinction between Todd's position and that in Ancare is that in that case, involving an application for revocation of patents, it was the defendants who were pursuing interrogatories of the plaintiff. Before the defendants had to settle the terms of their evidence, therefore, they would have the plaintiff's case by way of the briefs of its evidence. In contrast here, the interrogatories are pursued by the plaintiff, seeking to know further factual matters from the defendants before the plaintiff has to commit to the terms of its own evidence. I therefore consider that the situation in Ancare is distinguishable, when assessing whether Todd can make out necessity in respect of the questions posed in its interrogatories. [95] For Shell, Mr Taylor also relied on the decision in Shore for the further proposition: It is not incumbent upon the Court to sift and sort the mass, and where called for, to reshape the form of particular interrogatories. (695) [96] Mr Taylor's point was that if some aspects of the interrogatories could be rendered reasonable by amendment, then it was not for the Court to "save" such parts, because the onus was on the party wishing to interrogate to present necessary and reasonable questions. [97] On Mr Taylor's calculation, the potential application of eight variables to a series of questions divided into sub-parts would require consideration and, if ordered, answer to some 464 enquiries. He contended this was clearly oppressive. [98] On the third day of the hearing, Mr Olney produced an amended form of notice to answer interrogatories, following criticisms by Mr Taylor of the capacity in which the original form of interrogatories purported to require responses from Shell. The original interrogatories sought answers in respect of conduct by Shell "in its capacity as operator". Mr Taylor criticised this because the pleading against Shell criticised its conduct as a joint venturer, not as the operator of the venture. The amended form deleted references to "in its capacity as operator" and consistently with that also deleted references questioning the creation by Shell of documents where that occurred in Shell's capacity as operator. [99] Once that change had been made, perhaps predictably Mr Taylor then criticised the inappropriate nature of questions addressed to Shell as a joint venturer, because of the questions related to steps that had been taken by Shell as operator. [100] Considering first the necessity for the questions. I disallow questions 6 and 7 and 14 and 15 of the amended form because they seek documents that have been referred to or relied upon (questions 6 and 7) or correspondence between Shell and OMV (questions 14 and 15). There has been an apparently thorough process of discovery and inspection so that such questions could not be justified if it was anticipated that they would reveal documents not already discovered. To the extent that the questions seek to commit Shell to a characterisation of relatively how important certain documents are, that have already been discovered, I am not persuaded that that is a necessary topic that Shell should be required to answer. [101] It is difficult to attribute "necessity" to any particular factual enquiry in absolute terms. However, I am, for present purposes, prepared to accept that there is a measure of necessity in Todd knowing certain of the facts that would be addressed in answers to the remaining interrogatories. As against that, I am concerned about the oppressive extent of work which would be required to answer them anywhere near completely. One pervasive multiplier of the extent of work required is the stipulation in interrogatory 1 that answers should separately be provided for the "total production available" and "total production available (contingent)" separately for each of the 2007 to 2010 years, as well as the "total production available" for the 2006 year. From a preliminary consideration of Todd's Second Amended Statement of Claim (the Statement of Claim), and in particular the seventh to ninth causes of action which allege breaches of the Commerce Act, it does appear that any behaviour on behalf of Shell that might go to an anti-competitive purpose or effect will most likely have been manifested at or near the outset of the relevant period to which the broader scope of questions is directed. [102] Accordingly, I propose to disallow any interrogatories other than in respect of question 1(a) to (c), covering the 2006 and 2007 projections. I appreciate that this creates a risk of limiting the answers in an way that avoids Shell having to acknowledge some aspect of conduct subsequent to the period that I would allow questions to be asked about. I further acknowledge that the superficial level of my understanding of the nature of the competing cases and the commercial context in which the conduct has occurred do create a risk that I am drawing a distinction on an inadequately informed basis. However, I am well satisfied that to allow the questions over the longer, more recent periods would inevitably be oppressive. I am also satisfied that conduct on behalf of Shell that is likely to harm its own defence or assist Todd in it making out its causes of action is relatively more likely to have occurred when the pattern of their commercial conduct was being developed. [103] As to question 5 of the amended interrogatories, (d) and (e) could require Shell to make further enquiries of any relevant independent contractor or agent. In terms of marginal relevance weighed against the potentially oppressive extent of work required to answer, I do not consider such questions justified and accordingly disallow question 5, in respect of paragraphs (d) and (e). [104] As to question 16, I appreciate its potential importance for Todd in relation to the allegations of breach of the Commerce Act. However, in its present, relatively open-ended form, it is undoubtedly oppressive. Any communications between Shell and OMV that were likely to have commercial significance in the decisions subsequently made are unlikely not to have been recorded. I accept that if parties appreciate they may be conducting themselves contrary to the Commerce Act, then they may deliberately not create a record that would subsequently be discoverable. However, given the apparent nature of Shell and OMV's organisations in New Zealand, and the formality attributed to their April 2004 Alignment Agreement, I am not satisfied that Todd can lay a foundation for there being any realistic prospect of such unrecorded communications. Obviously, recorded conversations would be discoverable. Further, the question is open-ended as to time, and as to the personnel who may have been party to such conversations. I accept Mr Taylor's concern that there would be a real risk of inadequate answers, however conscientiously Shell made enquiries of existing and former personnel. This is not a question which I am prepared to confine on Todd's behalf so as to render it acceptable. Accordingly, questions 16 (and 17, 18 and 19, which are consequent either upon 16 or 14 and 16) are disallowed. [105] Questions 20 and 21 address the same factual enquiry in relation to the supply and demand model as was sought by way of further discovery in Todd's second application (see paragraphs [28] to [36] above). [106] In the context of this interrogatory, Mr Taylor still objected on the basis that it was oppressive, and that however conscientiously Shell might address the question, it could still not be sure of the complete accuracy of its answers. The question contemplates an entirely electronic process without any paper results having been produced (such documents would have been discovered, and there are none). Nor should there be any uncertainty as to the extent of electronic interrogation that Shell should be required to commission, in order to answer the interrogatories. [107] It appears that the interrogatory, as with the request for further discovery, is premised on the view of Mr Murray, the independent expert retained by Todd, that an organisation like Shell once having access to the model, would have used it to test the outcome at rates of production other than 70 PJ per annum. I would not be prepared to allow question 20 on the terms proposed in the amended notice. To prevent the imposition on Shell of oppressive obligations, I would permit an interrogatory in the more confined terms as follows: In the period up to the end of April 2006, did SENZL ever run any version of any electronic supply and demand model ("Model") with a production rate for the plateau period set at a rate other than 70 Pj/a? The answer to this question is to be confined to the electronic records currently available to SENZL, to the extent that such electronic records can be interrogated without incurring any substantial expense by way of information technology consultants, in deconstructing any overwriting of versions of the model that has previously occurred. [108] Question 21 is to be posed in respect of the confined terms of question 20. [109] Accordingly, I order that Shell is to answer Todd's amended notice to answer interrogatories dated 24 July 2009, except to the following extent: a) None of the answers need address question 1(d) to (h). b) Any answers needed to question 5 are not to address paragraphs (d) and (e). c) Questions 6 and 7 do not require to be answered. d) Questions 14 to 19 do not require to be answered. e) Question 20 is only to be answered in respect of the more confined version of it specified in paragraph [107] above. f) The scope of any response to question 21 is confined to those terms of question 20. Interrogatories, as against OMV [110] Todd seeks answers to a further series of interrogatories posed of OMV, some of which more or less parallel the topics raised in the interrogatories posed of Shell. Again, Mr Olney produced an amended form of questions on the second day of the hearing. The topics are, however, more confined. [111] For OMV, Mr Stephens spoke to his written submissions, helpfully adopting those aspects of OMV's opposition that mirrored the points already argued by Mr Taylor for Shell. In addition, he emphasised the lateness of Todd's request to answer the interrogatories, relative to the first pleading of allegations of breach of the Commerce Act in October 2006, the relatively small number of OMV personnel in New Zealand and the high level of turnover of such personnel since the events to which the majority of the questions posed for OMV related. [112] Question 1 of the interrogatories mirrors question 1 in the Shell interrogatories, and to the extent that any subsequent questions would be permitted, they would be confined in the same way as specified in paragraph [102] above. [113] Questions 2 to 5 in the interrogatories served on OMV are in comparable terms to questions 16 to 19 of those posed of Shell. They are disallowed for the same reasoning. [114] Questions 6 and 7 pose open-ended questions about a supply and demand model used by OMV, intended to elicit responses on the same matters as questions 20 and 21 in the interrogatories posed of Shell. [115] OMV's opposition to answering these questions is supported by an affidavit from Mr John Burt, the commercial executive of OMV based in Wellington. That describes the previous disclosure to Todd's advisers of various versions of an electronic model developed in August 2003 by Mr Burt's predecessor, Mr Michael Wright. This means that the model dates from the period when there was an assumption of joint marketing by all three venturers. Initially, OMV discovered version 10, and then versions 6, 7 and 9 of that model. It has also supplied electronic versions of all five versions of the model still in existence, namely 6 to 10. Mr Burt denies that there are any electronic or documented versions projecting a production rate higher than 70 PJ per annum, or indeed other than in the versions as already discovered. Apparently the versions that were near to being able to make a complete analysis (8 and 10) could not be run with a production variable higher than 70 PJ. The only version where that was possible was an incomplete draft. In OMV's case, these questions have effectively been answered in the negative, and I consider it would be oppressive to require the scope of enquiries necessary to formally respond. [116] Accordingly, I find that there are valid grounds for opposing each of the operative questions, and OMV is not required to answer any of Todd's proposed interrogatories. Further particulars, as against Shell [117] Relatively recently before the argument of these applications, Todd served notices on each of the defendants requiring them to provide further particulars of a small number of the paragraphs in their respective Statements of Defence. In pleading terms, this is a relatively complex case. There are 10 causes of action in the Statement of Claim, which runs to a little more than 25 closely typed pages. In general terms, neither Statement of Defence to it could be criticised as being evasive. The tactical consideration on this application reflects a fine balancing act. On the one hand, Todd has an interest in knowing adequately the matters of justification that will be raised in the arguments for Shell and OMV so as to avoid prejudice to Todd's case at trial by being taken by surprise. On the other hand, there is a wish to confine the defendants as specifically as possible by way of pleading so as to deny them the opportunity of raising additional matters that might otherwise advance their defences at trial. The authorities considering contested requests for particulars recognise the validity of the first concern, and are wary of intervening to an extent that might do no more than is justified on the second. See generally McGechan on Procedure HR5.21.01. [118] The first particular sought of Shell relates to a part of its response to Todd's allegation as to the effect of Article 10.1 of the PJVA. Shell has pleaded, in part: ...It says production from time to time is not determined by Article 10 but as a matter for determination in accordance with other terms of the PJVA, including Articles 5.2 and 6.3. [119] Todd seeks particulars of the provisions of the PJVA other than Articles 5.2 and 6.3 in accordance with which Shell alleges that production from time to time is to be determined. [120] The extent of particularity required in respect of contractual provisions and their interpretation is now guided by rr 5.19(3) and 5.20 of the High Court Rules. The former provision provides that a party asserting that the interpretation of a contract advanced by another is wrong must assert its own interpretation. That is balanced by the latter provision which provides that if a party relies upon any document in whole or in part, it is sufficient to state its effect as briefly as possible, without setting it out, unless the precise words are material. The combined effect of these two provisions will render inadequate in most situations the classic formulation for a defendant in a contract claim, simply denying the plaintiff's pleaded effect of the contract and signalling reliance on the whole document in terms such as "...and will rely on the contract as if exhaustively pleaded herein". What r 5.19(3) requires is for the defendant in such a situation to do more than simply deny the effect of the contract as pleaded by the plaintiff. The defendant's alternative interpretation of the contract must be pleaded, in its essence. [121] Shell resists the provision of an explicit list of additional contractual provisions which might bear on how the level of production is to be determined from time to time. Mr Taylor argues that if, in analysing all the provisions having any impact on this issue, one provision is left out, is Shell thereby prevented from presenting the full argument that would otherwise be available to it? [122] The effect of Shell's existing pleading gives primacy to the effect of Articles 5.2 and 6.3, but implicitly contemplates that their application will be influenced by other parts of the PJVA. I consider that specifying that relative level of importance is adequate. It is unnecessary, in understanding how Shell asserts the contract is to be interpreted, to specify all the other provisions that may have any influence on the interpretation of these (implicitly) primary provisions. Shell is not required to provide the further particulars sought of paragraph 6 of its Statement of Defence. [123] Todd seeks two particulars of paragraph 7 of Shell's Amended Statement of Defence, namely the identity of any off-take agreement and other agreements entered into by the joint venturers that incorporated arrangements for the disposal of gas. Mr Taylor did not resist provision of those particulars, and I accordingly direct that they are to be provided. [124] In paragraph 77 of the Statement of Claim, Todd alleges that certain documents in relation to off-take and resolutions passed by Shell and OMV adopting them constitute contracts, arrangements or understandings for the purposes of certain sections in the Commerce Act. Paragraph 77 of Shell's Statement of Defence pleads that such documents were approved "...for the purposes of the joint venture...". A response in those terms is likely to be relevant to the invocation of s 31 of the Commerce Act, which recognises an exemption from s 30 for activities undertaken by a joint venture. Todd now wishes Shell to state the relevant purposes of the joint venture referred to. [125] Such purposes are a matter for evidence and argument. I do not consider that Todd needs to know as a matter of pleading from Shell how it will couch those "purposes of the joint venture" in argument at trial. To require greater particularity would extend this beyond the proper scope of pleading. Shell accordingly does not have to respond to this particular. [126] Paragraph 80 of Todd's Statement of Claim pleads that the provisions of the off-take documents have the purpose, effect or likely effect of substantially lessening competition. Subsequent to denying that allegation, paragraph 80 of Shell's Statement of Defence pleads in the alternative that if the off-take documents are contracts, arrangements or understandings to which s 27 applies, then they were "authorised" for the purposes of facilitating production from Pohokura. [127] Todd now seeks particulars as to how and by whom the off-take documents were "authorised". Todd submits that it is entitled to have the pleading commit Shell to saying how and by whom such authorisation occurred. [128] In resisting a response on this, Mr Taylor submits that the authorisation can only derive from the terms of the agreement, and whether that is correct is a matter of interpretation and therefore a question of law. A distinction could be drawn between the joint venture agreement providing for a process by which such documents might be authorised, and the factual circumstances in which particular documents were alleged to be authorised pursuant to that process. Todd's request relates to the latter, whereas Shell's resistance contemplated the former. Shell is not required to provide that particulars of the contractual provisions for such a process. Nor do I consider it necessary for Shell to spell out the factual circumstances it alleges occurred in the case of these particular documents. Their history is a part of Todd's own pleading. Accordingly, this particular does not need to be provided. [129] In the same paragraph of the Statement of Claim, Todd alleges that the relevant market for competition law terms is the "national natural gas production (and first point of sale) market", which encompasses transactions between the producers of gas and the first point of sale customers (Gas Market)". Shell's response says that the Gas Market is not limited in the way defined by Todd. Todd has requested that Shell state what the limits of the Gas Market are if it is not limited in the way Todd's pleading defines it. The scope of the relevant market can be critical in a competition law analysis. The choice between competing economic analyses as to what constitutes the scope of a relevant market can be a vexed question, and the parties should disclose, in advance of the preparation of briefs of evidence, the alternatives contended for. [130] Here, Mr Taylor appeared to be wanting to keep Shell's options open to argue that the relevant market was to be more broadly defined than as Todd contends. This is too important to be left until Todd is served with Shell's briefs of evidence. Accordingly, Todd is entitled to have Shell respond to the second particular arising under paragraph 80 (as posed in question 6 of the notice dated 3 July 2009). [131] In summary, Shell is not required to provide the particulars sought in questions 1, 4 and 5, but will answer the particulars required in questions 2, 3 and must provide the answer to question 6. Further particulars, as against OMV [132] The first particular sought by Todd in respect of OMV's Statement of Defence relates to paragraph 6 of the respective pleadings and is substantially similar to the issue arising on the first particular sought by Todd of Shell. In OMV's case, its response to paragraph 6 of the Statement of Claim, in addition to a denial of Todd's alleged right and obligation to take its share of the total production capable of delivery, is: ...That "total production available to it under this agreement" in Article 10.1 does not mean petroleum which is physically capable of delivery at any given time, but means the total production of petroleum available in accordance with the production decisions made by the operating committee under the PJVA, including pursuant to Articles 5.2 and 6.3 of the PJVA. [133] As with Shell, Todd has asked OMV to state pursuant to which terms of the PJVA, in addition to Articles 5.2 and 6.3, it is alleged that the Operating Committee production decisions are made. [134] For the reasons identified in finding that Shell did not have to provide such further detail of the contractual provisions, the same outcome avails OMV. The specific identification of Articles 5.2 and 6.3 gives them a degree of primacy, but their interpretation and application in the context of the whole of the PJVA is a matter of argument. Such argument ought not to be artificially constrained by some exhaustive list of the other provisions that have any degree of influence on the interpretation and application of those primary provisions as relied on by OMV. [135] The second particular sought by Todd relates to paragraph 16 of OMV's Statement of Defence. That responds on the effect of matters agreed at a meeting on 30 June 2004 in the following terms: ...The Pohokura Joint Venturers unanimously approved the development of the Pohokura field according to the development plan providing for production of 70 Pj of natural gas per annum and the wells and facilities required to deliver that level of production. [136] The first particular sought by Todd in respect of this is whether OMV alleges that the effect of the 30 June 2004 approvals operate as an agreement to limit production from the field to a maximum of 70 PJ per annum. [137] This request raises an issue additional to that pleaded by Todd, and by OMV's response. There is a material difference between joint venturers agreeing to produce 70 PJ per annum, and the joint venturers agreeing that they would limit production to a maximum of 70 PJ per annum. The former does not necessarily encompass the latter proposition. In that sense, it is not within the conventional scope of a request for particulars that should be intended to render more precise what is inadequately particularised. Rather, it seeks to build on OMV's existing pleading by requiring OMV to commit to a subtly different point not addressed in the requisite paragraph of the Statement of Claim. [138] Whilst Mr Olney was concerned that this paragraph reflected an "evolving" case on OMV's part, Mr Stephens emphatically denied that, pointing out that this pleading is in the same terms as OMV's earlier pleading in its Statement of Defence served in April 2007. [139] The practical point, as expressed in OMV's written submissions, is as follows: In any event, OMV does not intend to argue that the 30 June 2004 resolution was a binding agreement among the Pohokura joint venturers to limit annual production to a maximum of 70 Pj per annum. [140] It is sufficient that that answer, which I understand to be consistent with the way OMV's case is presented in other respects, is conveyed in that way and OMV is not formally required to respond to the request for further particulars of its paragraph 16. [141] This approach also resolves the absence of need for a response by OMV to the second of the particulars sought by Todd in respect of OMV's paragraph 16. [142] Accordingly, OMV is not required to respond to any aspects of Todd's request for particulars of its Statement of Defence. Fifth application: Costs on application not argued [143] Todd separately sought further discovery against OMV, to gain access to additional "documents" reflecting OMV's work on a 2003 supply and demand model. There were no further documents of a conventional type, but OMV has subsequently volunteered further electronic models, without prejudice to its view that they are irrelevant. OMV supplied them because it considered it was pointless to withhold them and take up time arguing the matter before the Court [144] Todd and OMV now seek costs from each other on the preliminary steps in relation to the further discovery application. For OMV, Mr Stephens criticised Todd's application as having been filed prematurely. The urgency in pursuing the matter was, from his perspective, entirely of Todd's making because Todd had had the documents giving rise to the present request for further discovery since last August. Mr Stephens acknowledged that OMV did not respond within the initial period in which it indicated it would, but that there had been an explanation for this as the relevant OMV employee was unwell at the time. Mr Stephens said OMV was not warned that a slight delay in responding would cause the filing of a formal application, and that the matter was still being dealt with via correspondence at that time. [145] Further, Mr Stephens emphasised the lack of relevance of the further draft versions of the Excel spreadsheet which he characterised as just the work of one person working on an Excel spreadsheet, and producing incomplete working drafts. OMV is satisfied that these workings had no bearing at all on its decision-making. [146] OMV sought $1,760 for the work in responding to what it characterised as the unnecessary further discovery application. [147] From Todd's perspective, Ms Clarke argued that Todd was entitled to pursue the application when it did, and that it is vindicated in doing so because the initiative resulted in the disclosure of further documents which it claims may be directly relevant to the competition law aspects of the case. [148] As to timing, the lack of response from OMV is said to have left Todd with no alternative but to make a formal application so that the matter could be included for hearing at the fixture that had then been allocated for 22 and 23 July 2009. For its part, Todd seeks a total of $1,560 (including a filing fee of $600). [149] I have a measure of sympathy for OMV on this particular part of the interlocutory process. The urgency attributed to the matter by Todd was not clear at the outset, even if understandably driven by Todd's requirement to have any contested application ready for argument at the fixture that had already been allocated. OMV makes the point that once its solicitors wrote on 17 June 2009 answering the queries about OMV's model, the Todd application should have been withdrawn. Instead, OMV had to proceed with a notice of opposition and preparation for hearing. [150] However, it would be inappropriate to determine the merits of this discrete costs argument on terms accepting OMV's assertion as to the complete lack of relevance of the further versions of the model. [151] Further, the work on the matter must be kept in perspective. Both parties are involved in a major piece of litigation, in which there are bound to be contested interchanges progressing from informal correspondence to the perceived need for formal interlocutory applications. Resolution by the Court of costs' consequences where such differences are not argued is not to be encouraged. [152] It is not for the Court to question the economics of both sides preparing for and pursuing arguments for amounts of costs less than $2,000. There is, however, a concern that these parties have argued this costs issue for symbolic, rather than economic, reasons. [153] I am not prepared to make any order as to costs on the discovery application not argued. Costs are to lie where they fall. Costs on the present contested applications [154] That leaves the issue of costs on Todd's interlocutory applications that I have determined in this judgment. From Shell's perspective, it has successfully defended the separate application challenging confidentiality in its commercially sensitive documents, and the application for further discovery in respect of electronic records of its modelling. It has largely been successful in resisting Todd's application for further discovery of various types of documents. It has also successfully resisted the major part of Todd's application to administer interrogatories, and to require further particulars of its Statement of Defence. In these circumstances, I consider it ought to have an order in its favour on a 2B scale for the first two applications where it was successful in its defence, and as to two thirds of what would have been the entitlement to costs had it been entirely successful on the further discovery, interrogatories and request for further particulars application. [155] So far as OMV is concerned, it has been successful in resisting the application for interrogatories and particulars, and is entitled to costs on a 2B scale. Lay Member [156] On 8 July 2009, a joint Memorandum of Counsel requested the appointment of a Lay Member to sit with the Court in respect of the Commerce Act causes of action. That request was promoted by the plaintiff, and the defendants were not opposed, provided such an appointment did not jeopardise the allocated fixture. I issued a Minute on 14 July 2009 seeking clarification of the relative extent to which the evidence at trial would traverse matters not relevant to the Commerce Act causes of action. Although I invited a further joint Memorandum within 14 days, I took the opportunity to discuss the views of the parties with counsel at the conclusion of the hearing on 24 July 2009. [157] I raised with counsel first a concern that the Court may not have jurisdiction to convene with a Lay Member for the hearing of non-Commerce Act causes of action, and secondly to invite a response to the concern in my Minute about the extent to which the evidence would traverse non-Commerce Act issues. [158] As to jurisdiction, all counsel were agreed that the Court has jurisdiction to convene with a Lay Member in proceedings involving non-Commerce Act causes of action, provided that the Lay Member does not participate in any way in the non- Commerce Act aspects of the case. An appropriate precedent was the decision in Shell (Petroleum Mining) Co Ltd v Kapuni Gas Contracts Ltd (1997) 7 TCLR 463. In that case, Barker J sat with Mr R G Blunt in comparable proceedings utilising the expertise of the Lay Member to contribute to the analysis of the Commerce Act causes of action, with the Judge alone addressing the remainder of the issues. [159] I am accordingly satisfied that the jurisdiction does exist to appoint a Lay Member in the present proceedings. [160] As to the extent of non-Commerce Act evidence and argument, counsel were agreed that the majority of the evidence is likely to go to Commerce Act issues, and that it would be extremely difficult to divide either the evidence or argument, so as to allow for a Lay Member to not be present during the non-Commerce Act aspects of the case. [161] In the end, I accept that that is realistic, and that the advantages of having a Lay Member for the Commerce Act aspects of the proceedings outweighs the disadvantage for the Lay Member, and the Court, in having the Lay Member sit through the non-Commerce Act aspects of the case. [162] Accordingly, I order the appointment of a Lay Member and direct the Registry to make the appropriate arrangements. [163] As I emphasised to counsel, the taking of this step makes it even more important than is usually the case for the parties to be accurate in their estimate as to the time required for the hearing. Counsel were confident that the present estimate of six weeks is realistic and an accurate one. Summary [164] The outcome of the five interlocutory applications is as follows: a) Shell is entitled to uphold the confidentiality sought for its commercially sensitive documents. There is to be no variation to the existing regime for inspection. b) Todd's application for further discovery against Shell in relation to electronic records of its modelling for projected production levels at Pohokura, other than 70 PJ per annum, is dismissed. c) As to Todd's application for further and better discovery of other types of documents sought from Shell: i) GSA1 and GSA2 contracts have been volunteered. Documents commenting on GSA1 and GSA2, to the extent not already discovered, are irrelevant and there is no order for their discovery. ii) As to the five missing attachments, some are to be discovered in terms of the summary at paragraph [57]. iii) As to STOS documents, Shell is entitled to maintain a claim for solicitor/client privilege in all of these documents, subject to a minor exception specified in paragraph [70] above. iv) Common interest privilege/litigation privilege categories (a) to (c) for which Shell sought to invoke this form of privilege are excepted. There is no obligation on Shell to re-list those categories. As to (d) and (e), a small number are to be discovered in terms of paragraph [84] above. v) As to pre-contractual documents no order as to discovery is warranted. d) Todd application requiring answers to interrogatories and further and better particulars: i) As against Shell, a small number of the interrogatories are allowed and a small number of further particulars are to be provided (see paragraphs [109] and [131] respectively). ii) As against OMV, none of the interrogatories are justified and nor is the request for further particulars. e) No costs order is made on Todd's resolved application for particular discovery from OMV. f) Shell and OMV are entitled to costs on these applications in accordance with paragraphs [154] and [155] above. g) I have ordered that a Lay Member will sit with the Court to participate in the determination of the Commerce Act causes of action.
