(b) the development application said that SEPP 5 was about to be replaced by SEPP SL and communicated an intention that it should then be considered under SEPP SL;
(c) from the time SEPP SL commenced, both parties accepted and treated the development application as made pursuant to the unamended SEPP SL. Thus, if the council's acceptance of the applicant's communicated intention was required, the acceptance was in fact provided.

Notwithstanding that the council expressed a contrary position in its solicitors' letters of 4 and 8 April 2008, it has now informed the Court that it in fact adheres to that common position.

(3) Circumstances in which the Court might consider the making of a costs order to be fair and reasonable include (without limitation) the following:

(i) in one way was, or was potentially, determinative of the proceedings, and
(ii) was preliminary to, or otherwise has not involved, an evaluation of the merits of any application the subject of the proceedings…
(d) that a party has acted unreasonably in the conduct of the proceedings…
