The scope of the slip rule
26 The purpose of the slip rule is to avoid injustice to litigants (Gould v Vaggelas (1985) 157 CLR 215 at 274-5) by ensuring that the court's judgment or order reflects its intention at the time the order was made or the judgment was published, or reflects the intention that the court would have had but for the failure that caused the accidental slip or omission: Symes v Commonwealth (1987) 89 FLR 356 at 357. It may be exercised to prevent unintended consequences of the order and in this way give effect to the court's intentions: Newmont Yandal Operations Pty Ltd v The J Aron Corporation and the Goldman Sachs Group Inc (2007) 70 NSWLR 411 ("Newmont Yandal") at [116], [185], [194]. It is not confined to errors or omissions of the court; it extends to errors or omissions resulting from the inadvertence of a party's legal representative: L Shaddock & Associates Pty Ltd v Parramatta City Council [No 2] (1982) 151 CLR 590 ("Shaddock") at 594-5.
27 In Streimer v Tamas (1981) 37 ALR 211 Shepherd J suggested that the slip rule could be used to retrospectively extend the life of a bankruptcy notice. Later, in DDB Needham Sydney Pty Ltd v Elyard Corporation Pty Ltd (1995) 131 ALR 213 his Honour applied the rule to extend the time in which a winding up application could be determined. The Full Court dismissed an appeal from that decision in Elyard Corporation Pty Ltd v DDB Needham Sydney Pty Ltd (1995) 61 FCR 385 ("Elyard"). On the appeal the Court accepted that the slip rule may be invoked "where the proposed amendment is one upon which no real difference of opinion can exist" but noted that it does not apply if the amendment is a matter of controversy and does not extend to mistakes resulting from a deliberate decision (at 390-1 per Lockhart J, Black CJ agreeing).
28 Section 459R(1) of the Corporations Law (now the Corporations Act 2001 (Cth)), with which Elyard was concerned, required that an application to wind up a company in insolvency be determined within six months after it was made. Section 459R(2) conferred a discretion on the Court to make an order extending the period in which the application must be determined but only in special circumstances and, relevantly, only where the order was made within the six month period, or as last extended under the subsection. Section 459R(3) provided that an application is dismissed if not determined as required by the section. Counsel for the appellant in Elyard argued that the language of s 459R(2) required any application for an extension of time to be made before expiry of the period which had been the subject of an earlier extension made within the six month period, and that the application to wind up the appellant company was dismissed by operation of s 459R(3). In rejecting that argument, Lockhart J said at 391-3:
In my opinion, the argument rests on a misconception of the nature and operation of the slip rule. This is the case because the later order corrects the earlier order, and speaks from the date of the earlier order, which then operates with full force as corrected. Hence, the order made by the primary Judge in this case, on 9 August 1995, corrected the order of the registrar of 9 June 1995, which then operated with full force from 9 June 1995. The slip rule, with retrospective operation, corrected the earlier order … The essential purpose of the slip rule is to give effect to the intention which the Court would have had, if it were not for the failure which led to the accidental slip or omission.
…It is irrelevant that the later order ... which corrected the earlier order, was made after the expiration of the statutory time limit. The earlier order as corrected, and speaking by operation of the later order from the earlier date, operated with full force from a time which was within the statutory time frame.
…
[O]nce the earlier order has been corrected it speaks from the date of the earlier order, and it is deemed to have always operated from that date.
29 Lindgren J at 401-2 expressed the same view. Black CJ agreed at 387-8.
30 In Griffiths the Full Court expressed some disquiet about the decision in Elyard but declined to overrule it. It said (at [52]) that, although Elyard did not directly bind the Court in applying s 52 of the Bankruptcy Act, it would cause substantial confusion in insolvency practice if a different approach were taken in the bankruptcy jurisdiction.
31 Ms Flint maintained that Griffiths was not binding on this Court (the relevant remarks being obiter) and ought not be followed, and that Elyard was distinguishable. Nevertheless, during the hearing of the appeal Ms Flint accepted that the slip rule could be used in an appropriate case to extend the life of a creditor's petition after it had lapsed. Ultimately her submission was that its operation was not engaged in the circumstances of this case.
32 In Amorin Constructions Pty Ltd v Kamtech Electrical Services Pty Ltd (2008) 73 NSWLR 627 ("Amorin"), Hammerschlag J accepted that the application of the slip rule extended to the intention that the Court would have had but for the failure that caused the accidental slip or omission. However, his Honour pointed out that the power given to the Court to extend the period within which to determine a winding up application under s 459R(2) of the Corporations Act is conditioned on the Court reaching the requisite state of satisfaction, namely, "if it is satisfied that special circumstances justify it" and as such, undoubtedly involves the exercise by the Court of an independent discretion. On this basis, Hammerschlag J considered that Elyard was plainly wrong to hold that the slip rule could be invoked in these circumstances and expressed surprise that neither in Elyard nor in the cases that followed was there any consideration of this precondition to the exercise of the statutory power. He pointed out that for the most part, the orders were justified on the basis of the court's inherent jurisdiction. He referred to and applied Storey & Keers Pty Ltd v Johnstone (1987) 9 NSWLR 446 ("Storey & Keers") where McHugh JA said the following (at 453):
The rationale of the slip rule … requires that an omission or mistake should not be treated as accidental if the proposed amendment requires the exercise of an independent discretion or is a matter upon which a real difference of opinion might exist: cf Brew v Whitlock (No 3) (at 506).
33 In Brew v Whitlock (No 3) [1968] VR 504 at 506 the Full Court of the Victorian Supreme Court said that it was "impossible … to apply the rule to a case where, on the application to correct the judgement, it is necessary to exercise an independent discretion". Brew v Whitlock involved a failure by a party to apply for, and the court to order, interest under s 78 of the Supreme Court Act 1958 (Vic). The decision was approved on appeal to the High Court: Whitlock v Brew (1968) 118 CLR 445 ("Whitlock v Brew") at 457-8 (per Kitto J), 463-4 (per Taylor, Menzies and Owen JJ).
