33 It would be an extraordinary outcome, and entirely inconsistent with over 120 years of judicial authority (see Re St. Nazaire Co (1879) 12 Ch D 88) regarding the finality of litigation, for it to be accepted that in reliance of s 43 of the Interpretation Act a court may re-visit an order that has been formally entered or perfected for the purpose of considering whether the court should "amend or repeal" the order. See Ove Arup Pty Ltd v WorkCover Authority (NSW) (Inspector Mansell) (2005) 141 IR 78 and the authorities referred to at [12] to [23] including: Grierson v The King (1938) 60 CLR 43; Bailey v Marinoff (1971) 125 CLR 529; Gamser v The Nominal Defendant (1976) 136 CLR 145; DJL v The Central Authority (2000) 201 CLR 226 (the decision in Ove Arup was challenged in the Court of Appeal, however, the challenge was dismissed: Ove Arup Pty Ltd v Industrial Court of NSW (2006) 149 IR 193).
34 Section 5(2) of the Interpretation Act provides:
(2) This Act applies to an Act or instrument except in so far as the contrary intention appears in this Act or in the Act or instrument concerned.
35 Here, the Act concerned is the Industrial Relations Act. In our opinion, the manifest intention of that Act is to preclude the Court from reviewing, varying or setting aside an order it has made that has been formally entered or perfected, except in the limited circumstances prescribed by the Act and the Commission's Rules. An order will be formally entered or perfected in the circumstance described by the Full Bench in Ove Arup at [26]:
26 The practice in relation to judgments and orders made by the Commission in Court Session is that a written judgment is prepared that also contains any orders to be made. The orders are normally pronounced on the day of judgment and the parties are immediately provided with a written copy of the judgment and orders. No further steps are taken to formally enter the judgment in records of the Court. In this respect, pronouncement and entry may be said to occur simultaneously, entry having been made in the written judgment and by its delivery in open court. We consider this is the established practice for the purposes of r 89 of the Commission's Rules and, accordingly, the practice, procedure or usage of the Supreme Court, Court of Appeal or Court of Criminal Appeal referred to in r 89(5) of the Commission's Rules in respect of entry of judgments and orders is not applicable.
36 The circumstances in which a judicial order may be amended or set aside arise under s 170 of the Act, which provides:
(1) The Commission may, in any proceedings before it, make any amendments to the proceedings that the Commission considers to be necessary in the interests of justice.
(2) Any such amendment may be made:
(a) at any stage of the proceedings, and
(b) on such terms as the Commission thinks fit (including, if it can award costs in the proceedings, terms as to costs).
(3) If this Act, the regulations or a rule of the Commission is not complied with in relation to the institution or conduct of proceedings before the Commission, the failure to comply is to be treated as an irregularity and does not nullify the proceedings, any step taken in the proceedings, or any decision in the proceedings.
(4) For the purposes of subsection (3), the Commission may wholly or partly set aside the proceedings, a step taken in the proceedings, or a decision in the proceedings.
37 Further, r 151 of the Industrial Relations Commission Rules 1996 provides:
151 Minute of judgment or order
(1) Where there is a mistake in an order or decision, arising from an accidental slip or omission, a tribunal, on application by any party or of its own motion, may at any time correct the mistake or error.
(2) A tribunal, on application by any party or of its own motion, may, at any time, for the purpose of carrying out its intention and to express accurately its meaning, correct any order or decision.
(3) The power in this Rule is additional to the power in Rule 38.
38 Rule 38 provides:
38 Correction of orders or awards
(1) The Registrar may publish in the Industrial Gazette any correction which is necessary by reason of a clerical or printing error in an order or award as published.
(2) Where there is a mistake in an order or award, arising from an accidental slip or omission, the tribunal, on application by any party or of its own motion, may at any time correct the mistake or error.
(3) A tribunal, on application by any party or of its own motion may, at any time, for the purpose of carrying out its intention and to express accurately its meaning, correct any order or award.
39 Neither the Act nor the Rules of the Commission provide for any express power to the Court, as distinct from the Commission, to amend or set aside an order other than those we have identified in the preceding three paragraphs. Whilst s 170(1) provides that the Commission may, in any proceedings before it, make any amendments to the proceedings that the Commission considers to be necessary in the interests of justice, and such amendments may be made at any stage of the proceedings (s 170(2)(a)), s 170 does not grant power to amend proceedings once an order has been made disposing of those proceedings. What Barwick CJ stated in Bailey v Marinoff at 530 with respect to the New South Wales Court of Appeal applies equally to this Court, in our opinion:
Once an order disposing of a proceeding has been perfected by being drawn up as the record of a court, that proceeding apart from any specific and relevant statutory provision is at an end in that court and is in its substance, in my opinion, beyond recall by that court. It would, in my opinion, not promote the due administration of the law or the promotion of justice for a court to have a power to reinstate a proceeding of which it has finally disposed.
