(1) If the ACMA thinks that preparation of a marketing plan may be unduly delayed because of difficulties in preparing the plan so far as it relates to some of the frequencies within the part of the spectrum in respect of which the plan is to be prepared, the ACMA may:
(a) decide that, in order not to delay the preparation of a plan in relation to frequencies for which the difficulties do not apply, the task of preparing the plan should be divided into one of preparing more than one plan; and
(b) prepare those plans at different times.
(2) Each of the plans so prepared is taken to have been prepared under section 39 or 39A, as the case requires, and this Part applies to the preparation of each plan accordingly.
