If the conviction were alleged in a pleading, it would be a good answer that there was no such record ( Dr. Drury's Case [(1610) 8 Co. Rep., at p. 142 b; 77 E.R., at p. 691.]). It is 'utterly defeated and annulled' ( Lord Sanchar's Case [[1572] EngR 445; (1613) 9 Co. Rep. 117 a, at p. 119 b; [1572] EngR 445; 77 E.R. 902, at p. 906.]) … 'upon the reversal of a judgment against any person convicted of any offence, the judgment, execution and all former proceedings become thereby absolutely null and void … and [he] shall stand in every respect as if he had never been charged with the offence in respect of which judgment was pronounced against him' ( Archbold's Criminal Pleading, Evidence and Practice , 21st ed. (1893), pp. 226, 227)."
43 Starke J, in a separate judgment, stated, at 227, that the setting aside of the conviction on the appeal had the effect of abrogating and obliterating the conviction. This is consistent with the first of the passages in the plurality judgment set out above, but does not go so far as the statement: the person "shall stand in every respect as if he had never been charged". However, as I would understand this statement, it is a reflection of the principle of double jeopardy which would enable the accused person to raise a plea in bar.
44 Cavanough was considered by Campbell J (as his Honour then was) in Battenberg v Union Club [2005] NSWSC 242; 53 ACSR 263 which involved the effect of an annulled bankruptcy on the membership of a corporation, where the corporation's constitution specified that membership ceased upon a member's bankruptcy. His Honour also referred to a number of Victorian cases, the effect of which is that a conviction no longer stands once it is set aside, although those cases indicate that the charge upon which the conviction was initially based is not thereby dismissed: R v Lapuse [1964] VR 43; Lynch v Hargrave [1971] VR 99 at 102-107; Rimanic v Business Licensing Authority [2002] VSCA 64.
45 Under the Crimes (Appeal and Review) Act, there is no express power to dismiss the charge or to remit the matter to the Local Court. That is different from the orders that may be made on an appeal by way of rehearing under the Supreme Court Act, s 75A. Pursuant to s 75A, the Court of Appeal makes the order it considers ought to have been made at first instance, but first sets aside the orders made at first instance. The Court may also remit the matter to the first instance court, either in whole or in part: see the discussion by Basten JA in Spanos.
46 The DPP submitted that although the Crimes (Appeal and Review) Act did not provide for the making of an order dismissing the charge following a conviction being set aside by the District Court pursuant to s 20, a successful appellant would have available the plea of autrefois acquit if the same charge was laid again. The DPP also submitted that the Crimes (Appeal and Review) Act, s 73 may provide some insight to the resolution of this question.
47 It is not accurate in this context to refer to the plea of autrefois acquit. The Criminal Procedure Act 1986, s 156 makes provision for the plea of autrefois acquit in respect of a charge on indictment. Section 156 is an expression of the common law principle that pleas of autrefois convict and autrefois acquit may only be entered in proceedings on indictment: see State Pollution Control Commission v Tallow Products Pty Ltd (1992) 29 NSWLR 517 at 530-532. However, a plea in bar may be made where a plea of autrefois acquit is not available, for example, where proceedings are brought summarily, as was the case here, in order to give effect to the principle against double jeopardy: see Tallow Products at 570.
48 Section 73 provides that if a conviction is set aside on an appeal, the registrar of the appeal court must cause a memorandum to that effect to be endorsed on the conviction. The DPP said that the purpose of the memorandum required under s 73 was in effect to finalise the proceedings in a way which was consistent with the manner in which proceedings are finalised in the Local Court on the dismissal of a charge.
49 Under the Criminal Procedure Act, s 202 the Local Court makes an order either convicting the person of the charge, or dismissing the matter. If a charge is dismissed, the Local Court may give the accused person a certificate certifying that the matter has been dismissed: s 205(1); and must give such a certificate to an accused person if requested to do so: s 205(2). Pursuant to s 206, a certificate certifying that a matter has been dismissed, if produced, and without further proofs being required, prevents any later proceeding being brought in any court for the same matter against the same person. The certificate thus provides a statutory bar in circumstances where a person would otherwise be required to formally raise a plea in bar.
50 Although the s 73 memorandum is required to be endorsed on a person's conviction, the endorsement does not provide the same statutory protection from the laying of the same charge as is provided by the Criminal Procedure Act, s 206. It is possible that a prosecutor might seek to again bring an accused person to trial, in which case the person whose conviction had been set aside would be faced with the necessity of actively defending the proceedings on the basis of a plea in bar in respect of summary proceedings or autrefois acquit in respect of proceedings on an indictment. Accordingly, the question remains whether any order additional to the setting aside of the conviction ought to be made by the District Court so as to finally dispose of the matter.
51 A court of limited statutory jurisdiction has the express powers conferred by statute, as well as those powers which by necessary implication are required to enable the court to effectively exercise its jurisdiction: see Pelechowski v The Registrar; Court of Appeal [1999] HCA 19 at [50]-[51]; Director of Public Prosecutions v Shirvanian (1998) 44 NSWLR 129. In this context "necessary" does not mean essential, but means a power to make orders which are reasonably required or legally ancillary to the accomplishment of the express powers given by the relevant legislation. In this regard, the touchstone is "reasonableness": Pelechowski at [51], referring Pollock CB in The Attorney-General v Walker (1849) 3 Ex 242 at 255-256 [154 ER 833 at 838-839].
52 In the present case, the question for consideration is whether the District Court, to effectively exercise its jurisdiction under s 20 so as to ensure that upon setting aside a conviction, a person is not at risk of being recharged (or at least not at the risk of having to actively defend any further charge by a formal plea in bar), has any implied power to finally dispose of the matter. There are at least two possibilities. The first is that in addition to setting aside the conviction, the District Court could make an order dismissing the charge. The other is to remit the matter to the District Court for the purposes of that Court dismissing the charge.
53 In Director of Public Prosecutions (NSW) v Emanuel [2009] NSWCA 42; 193 A Crim R 552, Basten JA, obiter, considered the question whether by implication the District Court could order that a matter in respect of which there had been an appeal pursuant to s 11 be remitted to the Local Court. His Honour adverted, at [61], to the possibility that there was an implied power of remitter, at least where the challenge to the original Local Court proceedings was as to their validity. His Honour did not express a concluded view on this and in any event, that is not this case.
54 If it was to be contended that an order remitting the matter to the Local Court should have been made, two further questions would arise. One possibility would be an order which directed the Local Court to dismiss the charge. An order that the Magistrate determine the matter according to law might be an unintended invitation to rehear the matter. However, there is nothing in the Crimes (Appeal and Review) Act, Pt 3 which indicates that an implication of remitter is reasonably required to enable the court to effectively exercise its jurisdiction and the confusion in an order of remittal underpins the unlikelihood of there being an implied power of remitter. Further, if that was the order to be made, a question would arise as to whether the processes specified by the Criminal Procedure Act, ss 205 and 206 would apply. I consider it is doubtful that they would, as the certificate of dismissal and the statutory bar to the bringing of further proceedings provided for by ss 205 and 206 are predicated by the Local Court itself determining a criminal charge and deciding the proceedings should be dismissed pursuant to s 202.
55 The other possibility is that the District Court has the implied power to dismiss the charge, in addition to exercising the express power of setting aside the conviction. However, I am not persuaded that such a power is necessary in the sense referred to above. Under the express powers, the conviction may be set aside: Crimes (Appeal and Review) Act, s 20 and the conviction must be endorsed to that effect: Criminal Proceedings Act, s 73. That is sufficient to notify the prosecuting authorities of the outcome of the appeal. Should the prosecuting authorities seek to again bring the person to trial, the person is entitled to raise a plea in bar.
