(3) The discretion must be exercised judicially, that is, for reasons directly connected with the charge or the conduct of the proceedings; (at 557, 566, 568);
9 The general rule is that a successful defendant has a reasonable expectation that costs will be awarded in his or her favour: Latoudis v Casey at 557; Donald Campbell & Co v Pollak (1927) AC 732 at 811. But there may be conduct on the part of the defendant, sometimes called "disentitling conduct", which would justify not making an award in his or her favour, or would justify making a reduced award of costs. Thus, in Latoudis v Casey at 544, Mason CJ said:
However, there will be cases in which, when regard is had to the particular circumstances, it would not be just and reasonable to order costs against the prosecutor or to order payment of all the defendant's costs. If, for example, the defendant, by his or her conduct after the events constituting the commission of the alleged offence, brought the prosecution upon himself or herself, then it would not be just and reasonable to award costs against the prosecutor.
I agree with Toohey J. that, if a defendant has been given an opportunity of explaining his or her version of events before a charge is laid and declines to take up that opportunity, it may be just and reasonable to refuse costs. Likewise, if a defendant conducts his or her defence in such a way as to prolong the proceedings unreasonably, it would be just and reasonable to make an award for a proportion of the defendant's costs.
10 The illustrations noted in the above passage are not the only illustration of "disentitling conduct". Toohey J in Latoudis v Casey at 565, after giving the illustrations referred to in the passage quoted above, went on to say:
These illustrations are in no way exhaustive but what they point up is that a refusal of costs to a successful defendant will ordinarily be based upon the conduct of the defendant in relation to the proceedings brought against him or her.
11 In this Court, in Environment Protection Authority v Shell Co of Australia (2001) 113 LGERA 463 at 470, Bignold J was prepared to reduce the costs payable in favour of the defendant by reference to issues in respect of which, although reasonably raised, the defendant wholly failed. Similarly, in Owen v Willtara Construction Pty Ltd (Bignold J, NSWLEC, 11 December 1998, unreported) his Honour declined to award costs in favour of a successful defendant upon the grounds, firstly, that the defendant brought the proceedings upon himself and, secondly, that the defendant failed in some of the issues raised in his defence.
12 There is no complete analogy between the discretion to award costs in summary criminal proceedings and the power to award costs in civil proceedings (Latoudis v Casey at 543) but nevertheless "… there is no difficulty in applying in such proceedings principles akin to those applicable to the making or refusing of orders for costs in civil cases" (per McHugh J in Latoudis v Casey at 568). Hence, it is not improper to observe the note of caution sounded by Jacobs J in Cretazzo v Lombardi (1975) 13 SASR 4 at 16 (a personal injury case) against apportioning costs only on the success or failure of one party or the other on various issues of fact and law. It seems to me, with respect, that a useful statement of the proper approach was set out by Burchett J in Australian Conservation Foundation and Ors v Forestry Commission of Tasmania and Ors (1988) 76 LGRA 381 at 384, (a case involving judicial review of an administrative action) where he said:
A party against whom an unsustainable claim is prosecuted is not to be forced, at his peril in respect of costs, to abandon every defence he is not sure of maintaining, and oppose to his adversary only the barrier of one hopeful argument; he is entitled to rise his earthworks at every reasonable point along the path of assault. At the same time, if he multiplies issues unreasonably, he may suffer in costs. Ultimately, the question is one of discretion and judgment.
