A barrister must take
care to ensure that the barrister’s advice to invoke the coercive powers
of a court:
(a) is
reasonably justified by the material then available to the barrister,
(b) is
appropriate for the robust advancement of the client’s case on its
merits,
(c) is
not given principally in order to harass or embarrass a person, and
(d) is
not given principally in order to gain some collateral advantage for the
client or the barrister or the instructing solicitor or a third party out of
court.
