33 As to ground 3, his Honour noted in para [78] that the Marine Pollution Act does not impose any time limitation for the prosecution of offences before the Land and Environment Court. It may be that his Honour apparently intended to contrast it with s 54 which does impose a time limit of 2 years for prosecutions in the Local Court. However, there is nothing in the judgment to suggest that his Honour took the lack of a time limitation into account as a factor in the exercise of his discretion. Of course, if there had been a statutory limitation the claim for abuse of process on the ground of delay would have been irrelevant.
34 It is true, as Bignold J observed, that the s 8 charge arose directly out of Talbot J's decision to uphold the defendants' no case to answer on the s 27 charge (see ground 4), but this was merely an observation of fact. It did not imply that this was in any way the fault of the applicants and merely drew attention to the fact that there had been no determination on the merits.
35 The main ground in support of the claim of abuse of process, apart from the double jeopardy issue, was the issue of delay. It is therefore necessary to consider the whole history of the prosecutions.
36 The discharge having allegedly occurred on 14 November 1999, the master and crew were interviewed the following day and, following the deposit of a security undertaking in accordance with s 52V of the Act in the sum of $500,000, the "Pacific Onyx" was allowed to leave port; but it was not until 20 February 2002 (over 2 years later) that the summonses for breach of s 27 were filed in the Land and Environment Court.
37 On 17 April 2002, the applicants' solicitors wrote to the respondent's solicitors stating that their clients intended to plead not guilty as they considered that the facts and circumstances of the incident did not fall within s 27. The proceedings were heard on 20 and 21 February 2003 and on the latter day, Senior Counsel for the applicants made the submission earlier referred to, which was upheld by Talbot J in his judgment on 7 March 2003 dismissing the summons in each case.
38 Following the dismissal of the summonses, the applicants' solicitors wrote on 9 April 2003 requesting the return of the security undertaking, but in reply the respondent's solicitors pointed out that they had 3 months in which to lodge an appeal, and by Notice of Motion filed 14 April, the respondent sought an order that questions of law be submitted to this Court for determination. On 6 May 2003, the respondent was directed to file and serve the questions it intended to submit for determination no later than 14 days before the next hearing date on 1 August 2003. Notwithstanding a number of promptings from the applicants' solicitors, the respondent failed to provide such questions and ultimately, on 30 July 2003 notified the Court and the applicants' solicitors that she no longer intended proceeding with the application to the Court of Criminal Appeal.
39 Not surprisingly, the applicants' solicitors again by letter dated 30 July requested the return of the security undertaking, but the respondent's solicitors refused to do so stating that the prosecutor would shortly be issuing proceedings against the applicants pursuant to s 8 of the Act. It was however, not until 28 October 2003 that the fresh summonses were filed. The delay from July to October was partly explained by the perceived need to have all the affidavits re-sworn for the fresh proceedings, and some of the deponents were difficult to relocate. The result of this was that the current prosecutions were commenced almost 4 years after the commission of the alleged offences.
40 Such delay reveals a desultory approach to the prosecutions which is to be deplored. Notwithstanding the applicants' solicitors letter of 17 April 2003, the respondent and those advising her made no effort to ascertain the basis of the assertion, but pressed on with the prosecutions under s 27. After those proceedings were dismissed by Talbot J, the respondent and those advising her first considered an appeal by way of Stated case but, after wasting more time, changed their minds and decided to lay the fresh charges, which themselves took another 3 months to be instituted. This ignores the initial delay between the date of the alleged discharge and the commencement of the original proceedings in February 2002, a delay of over 2 years, which delay remains completely unexplained.
41 Persons being prosecuted for serious offences, and these offences each carry maximum penalties of $1.1 million in the case of a corporation and $220,000 in the case of an individual, are entitled to have any charges being preferred against them instituted promptly. This is even more so where the Prosecutor is holding a security undertaking for half a million dollars. His Honour dealt with delay at [77] as follows:
"Although there had been a lapse of four years from the date of the alleged offence until the laying of the present prosecutions that delay is in large part taken up by the laying of the original charge and the prosecution of the charge against each Defendant. The Defendants did not allege any particular prejudice by dint of delay and they have been on notice of the discharge incident from when it occurred (when it was investigated by the Port officials) and had been aware of the Prosecution evidence when the first charges were laid against them."
42 Ground 5 is that his Honour erred in finding the fact that the applicant had "been on notice of the discharge incident from when it occurred" was a relevant factor in determining the extent of prejudice to which the applicants had been subjected.
43 Delay of itself does not constitute abuse of process or justify a permanent stay unless it can be shown that the delay is such that the defendant will suffer such prejudice as cannot be otherwise remedied and which will result in an unfair trial: Jago at 34, 59-60 and where delay is relied on it is necessary to consider whether, or to what extent the defendant is prejudiced by the delay. His Honour took into account that the applicants did not allege any prejudice to them as a result of the delay, and as a matter tending against any prejudice, the fact that they were on notice of the discharge from the time of its occurrence, and had known of the evidence to be led against them from the time of the laying of the s 27 charges. It was proper for his Honour to have regard to these matters in considering whether the applicants were prejudiced by the delay and ground 5 is not made out.
44 Finally ground 6 asserts that his Honour erred in failing to give the applicants the benefit of the full force in effect of their acquittals on the s 27 charges before Talbot J.
45 It is now well established that an acquittal may not be questioned or called into question by any evidence which would overturn or tend to overturn an acquittal, which must be accepted in future cases as incontrovertibly correct: Garnett v The Queen (1977) 139 CLR 437 at 445, The Queen v Storey (1978) 140 CLR 364, The Queen v Carroll (2002) 213 CLR 635.
46 In Carroll, the respondent had given evidence in his trial for murder denying that he had killed the deceased and had been acquitted. Years later, he was charged with perjury arising out of such evidence on the ground that in fact he had killed the deceased. The subsequent proceedings were permanently stayed because, although the charges were not the same and accordingly the ordinary principles of autrefois acquit and double jeopardy were not applicable, the crucial issue in each case was whether the respondent had killed the deceased; and a guilty verdict in the perjury trial would directly controvert the acquittal in the earlier murder trial, which the Crown Prosecutor conceded was the object of bringing the perjury charge.
47 The position here is quite different. The s 8 charges do not seek to controvert the acquittals on the s 27 charges, but rather accept them, as the ground for acquittal on the s 27 charges was that the evidence for the prosecution established that the discharge was one to which Part 2 of the Act applied and therefore Part 4 did not apply, the ground for acquittal on the s 27 charges.
