[20] The contentions of the appellants are, first, that the Powers of Attorney did not authorise the Attorney, Peter Siahos, to do an act which was for his own benefit rather than that of his parents, secondly, that it should be concluded that Mr Karefylakis' only possible authority from the appellants to direct payment of part of the loan funds to the ANZ Bank was from a purported exercise by Peter Siahos of authority granted by the Powers of Attorney and, thirdly, that Peter's instruction to Mr Karefylakis to direct payment of $181,682.82 to the ANZ Bank was an act for Peter's benefit and not that of his parents."
7 The argument upon which the defendants succeeded on appeal was thus a refinement, or on another view an elaboration, of the original argument based on s 12 of the Act. That argument as originally configured was the significant issue before me. However, the proceedings before me were not limited to that issue. The defendants lost on some of the issues that remained in contention and abandoned others before the hearing had proceeded very far.
8 In considering the question of who should pay the costs of the original hearing I think that I should do so by first asking myself what costs order I would have made if the defendants had succeeded before me on the power of attorney/authority point that they successfully ran in the Court of Appeal having regard to the fact that they did not proceed with or succeed upon all of the issues that were in contest at the start of the hearing. Approaching the matter in that way I consider that I would have ordered the plaintiff to pay the defendants' costs of the whole of the proceedings before me. This is for the following reasons.
