11 The defendants made three pre-hearing offers of admissions, expressed to be Calderbank letters, as to the volume and location of oil spillage, none of which were accepted by the prosecutor:
(a) on 11 August 2006 the owner and master offered to admit that 15 litres of oil were discharged at HMAS Waterhen;
(b) on 4 December 2006 the owner and master offered to admit that 35.79 litres of oil were discharged at HMAS Waterhen in return for the prosecutor agreeing to confine any allegation of oil spillage to that location and not seek to advance a case of failure to notify an oil discharge on behalf of any member of the crew. This volume was Mr Booker's estimate of the maximum amount of oil that could be lost from the port side stern system in any circumstance. The letter stated that acceptance would significantly shorten the penalty hearing time to half a day rather than the three days currently allocated; and
(c) on 13 February 2007 all the defendants offered to admit that 35.79 litres of oil discharged into State waters.
12 The prosecutor replied to the second offer stating that the Calderbank principles do not apply in criminal proceedings and that s 131 of the Evidence Act 1995 (NSW), which provides for the exclusion of evidence of settlement negotiations, does not apply in criminal proceedings. The letter also stated that the offerors had overlooked that the prosecutor has a duty to inform the Court of all salient matters and to provide the Court with the correct summary of events. Accordingly, for those reasons, the prosecutor did not accept the offer.
Prosecutor's submissions
13 In summary, the prosecutor's submissions in support of an order that the defendants should pay the prosecutor's costs were as follows:
(a) the normal principle is that costs follow the event in the absence of disentitling conduct: Warringah Council v Koch and Severino [2006] NSWLEC 608 at [4] citing Latoudis v Casey (1990) 170 CLR 34;
(b) the prosecutor was successful. The issue of substance was whether the defendants should be given the benefit of s 10 of the Crimes (Sentencing Procedure) Act 1999 or, rather, be convicted and fined. The primary question in that regard was the respective defendant's culpability for the oil discharges. The issue was resolved against the defendants;
(c) the prosecutor's case was that the defendants were imprudent in moving the vessel from Garden Island when they were aware that there had been an oil spill a few weeks earlier and indicia of a possible oil spill during sea trials early on the day in question. The critical question was not whether there was a discharge before the vessel reached Garden Island but whether that was a possibility;
(d) the Court accepted the prosecutor's case that the prudent course of action would have been to take precautionary steps at Garden Island. That was the reason why the defendants were not afforded the benefit of s 10 of the Crimes (Sentencing Procedure) Act 1999 ;
(e) there was no evidence of disentitling conduct by the prosecutor. It is by no means clear that the Calderbank principles apply in proceedings such as this: Latoudis at 543, 568; s 131 Evidence Act 1995 . Even if they do, they would not result in a departure from the usual order in this case. The fact that the prosecutor did not accept pre-trial offers of admission concerning the quantum or location of oil spills was no reason for departing from the usual order because it was inappropriate to accept them. The first offer on behalf of the owner and master was to admit that 15 litres of oil discharged at HMAS Waterhen. It was inappropriate to accept because the prosecutor had evidence of apparent reliability that the discharge exceeded 15 litres and occurred at other locations and the prosecutor proved a discharge at Garden Island. The second offer on behalf of the owner and master was to admit a discharge of 35.79 litres of oil at HMAS Waterhen and imposed a condition that the prosecutor not advance a case of failure to notify of an oil discharge on behalf of any crew member. It too was inappropriate to accept. The third offer on behalf of all three defendants was to admit to a discharge of 35.79 litres into State Waters on terms that the defendants were free to call evidence and make submissions. Acceptance would have made little difference to the conduct of the hearing. The place of discharge, its cause and the proper reaction of the defendants could not readily be disentangled from the amount of oil discharged;
(f) no matter was needlessly contested. The prosecutor had a duty to present all the evidence to the Court. The prosecutor had strong evidentiary support for its case. The contemporaneous documentary material of the chief engineer and his affidavit evidence were such that the prosecutor was duty-bound to test it. The prosecutor also had supporting expert evidence of the experienced Mr Burge;
(g) as for the three reports of Mr Burge, who was cross-examined for a long time, the first went to issues of culpability, the second was a response, and the third was a response to a later report of Mr Hunter in the chief engineer's case;
(h) the issue of quantum of oil spilled, considered as a discrete question, did not in any event take up a large part of the case and was a subsidiary issue. If the issue was severable, then it would be within the proper scope of the Court's discretion to order that the prosecutor not have its costs of that issue or make some allowance for its costs in respect of that issue. In that event the only evidence that can be isolated to that issue are the reports of Dr Lincoln-Smith and Dr King; and
(i) there should be taken into account that a costs order was made against the prosecutor at the hearing in relation to an unsuccessful application by the prosecutor.
Defendant's submissions
14 In summary, the defendants' submissions in support of an order that there be no order as to costs, or alternatively, that the defendants pay no more than a small proportion of the prosecutor's costs, are as follows:
(a) the prosecution failed in its case that oil was continuously discharged over a minimum distance of 4.85 kilometres of waterways;
(b) the defendants' case was that the only discharge of which they were aware was about 15 litres at HMAS Waterhen and, in the case of the chief engineer, some droplets at Garden Island. The defendants' case was accepted;
(c) the prosecutor's case that there was a continuous discharge of oil was based primarily on the expert reports of Mr Burge and Professor Coster. The Court found that their opinion was based on a misinterpretation of Mr Cosh's report;
(d) the prosecutor's expert reports of Dr Lincoln-Smith and Dr King were based on the premise that there was a continuous discharge of oil;
(e) the issue of the amount and location of oil discharge on which the prosecutor failed is severable and took up a considerable part of the hearing time. The estimate of the owner and master is more than two thirds of that time. The estimate of the chief engineer is 70 to 80 percent. In any event, the prosecutor ought not to have the cost of the various expert reports;
(f) section 10 of the Crimes (Sentencing Procedure) Act 1999 was not the defendants' dominant goal or the only issue and, even in that context, the issue of continuing discharge was significant;
(g) the prosecutor's conduct prior to and during the hearing occasioned unnecessary litigation and expense and the prosecutor obtained a result which was no better than that set out in the defendants' pre-trial statement of facts. In particular:
(i) prior to the hearing the prosecutor failed to accept the defendants' offers to agree the quantum of discharge of oil at between 15 and 35.79 litres;
(ii) the prosecutor took no steps to question the chief engineer before the hearing (as happened with the master) to test his contemporaneous records; and
(ii) on 22 February 2007 it was clear from Mr Burge's cross-examination that he had misinterpreted Mr Cosh's report in forming an opinion that there was a continuous discharge. Between that date and when the proceedings against the chief engineer resumed on 7 May 2007 he realised that his opinion could no longer be sustained. That was not disclosed in his supplementary report. The prosecutor nevertheless read Professor Coster's report in May 2007 which was based on the same misinterpretation.
Discussion
15 The focus of the submissions was the prosecutor's failure to establish that there was a continuous discharge of oil around Sydney Harbour, which the prosecutor had particularised at between 40 and 85 litres over a minimum of 4.85 kilometres. The Court found that there was a discharge of between 5 and 15 litres at HMAS Waterhen and a very small amount at Garden Island.
16 The broad issues are whether the prosecutor should bear his own costs in relation to that issue because:
(a) the prosecutor lost that issue which was large and severable; or
(b) the prosecutor's conduct in relation to that issue before and during the hearing was unreasonable.
Apportionment where prosecutor succeeds only upon a portion of the case
17 In my opinion, where a prosecutor has succeeded only upon a portion of his case, the circumstances may make it reasonable that it bear the expense of litigating that portion upon which it has failed. That may be where the prosecutor has failed on a dominant or separable and substantial issue. I understand the parties to accept that principle, although they are in dispute as to its application in the present case.
18 The apportionment principles are conveniently stated by the Court of Appeal in James v Surf Road Nominees Pty Ltd [No 2] [2005] NSWCA 296 at [32] - [36] and were applied by the Court of Appeal in Roads and Traffic Authority (NSW) v McGregor (No 2) [2005] NSWCA 453 at [17]. Although they were civil cases, the principles are, in my view, the same in criminal proceedings, consistently with the approach in Latoudis (save insofar as they may be modified by statute). In James the Court of Appeal held:
32. The effect of Pt 52A r.11 is that an unsuccessful party may be ordered to pay the entirety of the costs of the successful party, even though the successful party did not succeed on all issues. However, as is specified by the rule itself, the Court is entitled to make a different order. That may occur where there are multiple issues involved. This was the subject of comment in Waters v. P C Henderson (Aust) Pty. Limited (unreported CA(NSW) Kirby P, Mahoney and Priestley JJA, 6 July 1994) where Mahoney JA said:
Where the proceedings involve multiple issues the application of the rule that costs follow the event may involve hardship where a party succeeds on some issues and yet fails on others. Particularly is this so where, for example, a defendant succeeds on issues that occupied the bulk of the time taken by the proceedings. Nevertheless, unless a particular issue or group of issues is clearly dominant or separable, it will ordinarily be appropriate to award the costs of the proceedings to the successful party without attempting to differentiate between those particular issues on which it was successful and those on which it failed.
