The requirement for leave
4 The parties all approached the present application upon the basis that the applicant required leave to bring his proposed appeal from the Primary Judgment. It was accepted that the Primary Judgment was interlocutory in nature.
5 Although the question is probably something of a distraction, it is in my view quite possible that the applicant does not require leave to appeal. Pursuant to s 24(1A) of the FCA Act, leave to appeal is required before an appeal may be brought from an interlocutory judgment. As the authorities make clear, the line that divides interlocutory judgments from final judgments is not always easily drawn. But, in the present case, there seems limited scope for debate. The relief that was granted (and in respect of which the applicant seeks to appeal) was declaratory relief. There is no such thing as an interlocutory declaration: Dovuro Pty Limited v Wilkins (2003) 215 CLR 317, 359 [127] (Kirby J), 363 [143] (Hayne and Callinan JJ); Australian Competition and Consumer Commission v Cement Australia Pty Ltd [2014] FCA 148, [11] (Greenwood J). If the relief that was granted was not interlocutory relief, it must have been final relief: Warramunda Village Inc v Pryde (2002) 116 FCR 58, 77 [68] (Finkelstein J, Lee and Gyles JJ offering no view). It seems axiomatic to me that the judgment by which that relief was granted was a final, rather than interlocutory, judgment.
6 That, though, might be too simplistic an analysis. In N and E Bowder Pty Ltd v Australian Keg Company Pty Ltd (2014) 220 FCR 166, Rangiah J held that a judgment granting declaratory relief in respect of a separate question did not dispose of the whole of the proceeding to which it related and was, therefore, interlocutory in nature. His Honour noted (at 167-168 [8]-[9]):
8 There is a division of authority in this Court as to whether a declaration made in respect of a separate issue which does not dispose of the whole proceeding is interlocutory or final. A long line of authority holds that such a judgment is interlocutory: see, for example, the judgments of the Full Court in Australian Builders' Labourers' Federated Union of Workers - Western Australian Branch v J-Corp Pty Limited (1993) 42 FCR 452 at 454; Fisher & Paykel Healthcare Pty Ltd v Avion Engineering Pty Ltd (1991) 103 ALR 239 at 242; Caboche & Anor v Ramsay & Ors (1993) 119 ALR 215 at 226; NZI Securities Australia Ltd v Poignand (1994) 51 FCR 584 at 593-594; Fraser v NRMA Holdings Ltd (1995) 55 FCR 452 at 457; Construction, Forestry, Mining and Energy Union v Employment Advocate [2001] FCA 1442 at [8]-[9]; Lewis v Hall [2005] FCAFC 251 at [7]. These cases applied the reasoning of the High Court in Computer Edge Pty Ltd v Apple Computer Inc (1984) 54 ALR 767 at 767-768.
9 Other decisions of this Court support the view that a declaration made in respect of a separate issue which does not finally dispose of the case is a final judgment, so that leave to appeal is not required. That view was strongly expressed by Finkelstein J in Warramunda Village Inc v Pryde (2002) 116 FCR 58 at [65]-[70]. In Ho v Grigor (2006) 151 FCR 236, the Full Court cited those passages from the judgment of Finkelstein J with approval. However, the Full Court was not directly deciding the question addressed by Finkelstein J and its apparent approval of those views appears to be obiter dicta. For present purposes, I consider that I am bound by the earlier Full Court decisions to conclude that the judgment was interlocutory and that leave to appeal is required.
7 By contrast, Tracey J in Damorgold Pty Ltd v JAI Products Pty Ltd [2014] FCA 448 considered whether leave to appeal was required in respect of a judgment given on the trial of a separate question. His Honour expressed the view (at [9]):
I am not persuaded that the applicants require leave to appeal. In TAG Pacific Limited v McSweeney [1992] FCA 168; (1992) 34 FCR 438 Olney J held that, in a split trial in which questions relating to liability are ordered to be determined as preliminary questions, orders finally determining those questions are not to be treated as interlocutory: see at 444-5. A similar conclusion was reached by the majority of the Full Court of the Supreme Court of Victoria in City of Camberwell v Camberwell Shopping Centre Pty Ltd [1994] 1 VR 163 at 173-175. See also Cairns B, Australian Civil Procedure (10th ed, Lawbook Co, 2013) at 568-569. The orders made by His Honour in relation to the revocation of the patent bear the same character of finality as would have attended such orders had they been made following a trial in which questions of liability and relief had been considered in the normal manner. Left undisturbed those orders would finally determine the issues relating to the validity of the patent. They fall within the defined meaning of the word 'judgment' for the purposes of s 24(1) of the Act.
8 Given the regrettable uncertainty, practitioners might be forgiven for erring on the side of caution and seeking leave to appeal in circumstances such as the present, even if it's not strictly necessary to do so. Perhaps it is better to seek what might not be required than to risk substantive failure for want of something that is.
9 Fortunately, I need not attempt to navigate that minefield. Assuming (as I do - and as the preponderance of authority seems to indicate) that leave to appeal is required, it is appropriate in the present circumstances to grant it. If it is not required, then the applicant requires in any event an extension of time within which to initiate his appeal, the granting of which calls for consideration of similar issues: Singh v Minister for Immigration and Border Protection [2017] FCAFC 195 (Perram, Farrell and Perry JJ). Either way, it is appropriate, for the reasons outlined below, to permit the appeal to proceed.
