17 As to the first basis, that the Regulation is a savings or transitional provision permissible under par 1(1) of the Schedule, it was accepted that the Regulation was in its terms or its operation (or both) inconsistent with par 6(1) of the Schedule but it was put that this was nevertheless permissible because the words in s 4(2) "not inconsistent with this Act" mean not inconsistent with the Act as a whole, par 1(1) of the Schedule is just as much part of the Act as is s 4(2), and that paragraph itself has no limitation that a regulation under it not be inconsistent with the Act. In conjunction with this submission it was put that it was inevitable (that is there was no conceptual possibility to the contrary) that any savings or transitional regulation contemplated in par 1(1) of the Schedule would be inconsistent with the remainder of Pt 3 of the Schedule.
18 Hence, it was put, so as to give par 1(1) of the Schedule any field of operation, it must be read as authorising regulations inconsistent with other provisions in Pt 3 of the Schedule. Support for this approach was derived from the principles of statutory construction referred to in the well known passage in the judgment of the High Court in Project Blue Sky Inc v Australian Broadcasting Authority (1998) 194 CLR 355 at 381-382. Those principles include that a court construing a statutory provision must strive to give meaning to every word of the provision and must strive to give each provision the meaning which best gives effect to its purpose and language while maintaining the unity of the statutory scheme.
19 The first basis put is, in my view unsustainable. In Project Blue Sky Inc v Australian Broadcasting Authority the High Court cited with approval the statement of Lord Herschell LC in Institute of Patent Agents v Lockwood [1894] AC 347 at 360 to the effect that "[r]econciling conflicting provisions will often require the Court to determine which is the leading provision and which is the subordinate provision, and which must give way to the other". Paragraph 1(1) of the Schedule is not a separate and independent regulation making power. "The regulations" referred to in that paragraph are regulations which are made, and only made, under s 4(2). Section 4(2) is the leading provision and par 1(1) of the Schedule, the subordinate one. Paragraph 1(1) must give way to s 4(2). Any regulation which is made must not be inconsistent with the Act even if it is a regulation under par 1(1) of the Schedule and there is nothing in that paragraph which either expressly or by implication permits an outcome inconsistent with other provisions of the Act.
20 It also is not the case, in my view, that every conceivable savings or transitional provision capable of being made under par 1(1) of the Schedule necessarily involves inconsistency with - that is diminution of or derogation from rights granted under - other provisions of Pt 3 of the Schedule. It was accepted by Mr Perram on behalf of the Attorney that if there was scope for a savings or transitional provision made under par 1(1) of the Schedule which was not inconsistent with other provisions in Pt 3 of the Schedule, the argument was bound to fail.
21 Mr Gageler SC who, together with Mr Smith, appeared for Origin, gave the following example of a conceivable savings or transitional provision permissible under par 1(1) of the Schedule which would not be inconsistent with Pt 3 of the Schedule. Paragraph 6(2) of the Schedule refers to Pt 7 of the Act (which amongst others gives a defence of self-defence). It introduces what would be a new defence in respect of proceedings already commenced in a court. An example of a valid savings and transitional regulation which was not necessarily inconsistent with Pt 3 of the Schedule would, he put, and I agree, be one which was directed to the costs of proceedings commenced on or after 3 September 2002 and on foot at the time Pt 7 of the Act commenced.
22 Counsel for Bestcare submitted that although a regulation in those terms would be valid under s 4(2) and par 1(1) of the Schedule, it would nonetheless be inconsistent with Pt 3 of the Schedule. It was submitted that prior to such a regulation being made, the determination of a defendant's entitlement to costs upon the plaintiff discontinuing the matter would have depended upon the ordinary rules as to costs. The Schedule left those rights and liabilities intact, and provided for the status quo ante to be maintained notwithstanding the enactment of Pt 7 of the Act. The proposed regulation alters those rights and liabilities and hence would necessarily be inconsistent with the Schedule. I do not agree. The Act neither expressly nor impliedly provides for rights and liabilities in relation to costs, and consequently the proposed regulation does not present any inconsistency in that regard.
23 Further, in my view, there is scope for regulations contemplated in par 1(1) of the Schedule to work in a subordinate way with s 3B(3) as might be thought to be the case with the Regulation in this case, as appears below.
24 I turn to the second basis put, namely, that the Regulation comes within the express terms of s 3B(3). This provision, which like the Schedule is equally part of the Act, has a different quality to par 1(1) of the Schedule. It expressly contemplates the exclusion by regulation from the operation of the Act of a specified class or classes of civil liability which would otherwise be covered. Whether or not this inevitably entails the regulation being inconsistent with the Act, it, in my view, contemplates that possibility. Because this possibility is contemplated by the Act itself, a regulation within it is not inconsistent with the Act.
25 For the exclusion by regulation under s 3B(3) to be valid it must satisfy the requirement of being an exclusion of a specified class or classes of civil liability.
26 The question is thus whether what is excluded by the Regulation from the operation of the Act is a specified class or classes of civil liability.
27 Mr Gageler put that what was excluded here was not a "class of civil liability".
28 The argument entailed the following series of propositions. The term "civil liability" is not itself defined in the Act; the heads of civil liability specified in ss 3B(1) and 3B(2) were all classes of civil liability where the class is delineated by the circumstances giving rise to the liability; the term "class or classes of civil liability" in s 3B(3) should be construed ejusdem generis (or perhaps more accurately noscitur a sociis: Prior v Sherwood (1906) 3 CLR 1054) to mean a category or categories of civil liability so delineated, and delineated only, by specified circumstances without any temporal barrier; here the purported delineation imposed by the Regulation was according to time and not circumstance; ergo the delineation here was not by "class or classes of civil liability".
29 In my view this argument is unsustainable.
30 Part 4 of the Act is concerned with what are termed apportionable claims which are delineated by the circumstances giving rise to those claims. The Part does not cover the entire field of civil liability. A class is a group the members of which come within a certain category or description defined by a general or collective formula: Pearks v Moseley (1880) 5 App Cas 714 at 723 per Lord Selborne; ASX Operations Pty Ltd v Pont Data Australia Pty Ltd (No1) (1990) 27 FCR 460 at 488. The term "class" is defined in the Macquarie Concise Dictionary, 4th ed at 221 as "a number of persons, things, animals etc., regarded as forming one group through the possession of similar qualities; a kind; sort". In my view, Pt 4 applies to a category or categories of civil liability. Hence, in my view, the Part represents a class or classes of civil liability defined by a general or collective formula.
31 This delineation is according to the circumstances which give rise to the civil liability concerned.
32 Additionally, there is difficulty with the proposition that the meaning of "class or classes of liability" in s 3B(3) is to be interpreted ejusdem generis with ss 3B(1) and 3B(2). The term "class or classes" is not to be found in the earlier subsections. There does not seem to be a discernible and workable genus capable of being extracted from the earlier subsections: The King v Regos & Morgan (1947) 74 CLR 613 at 623-623 per Latham CJ; Canwan Coals Pty Ltd v Commissioner of Taxation [1974] 1 NSWLR 728 at 733. Finally, even if the ejusdem generis canon of construction were to be appropriate, no good reason was proffered why Pt 4 claims do not fall into the genus derived from the earlier subsections.
33 Mr Gageler was ultimately driven to put that if Pt 4 claims were a class (as they appeared to be on the basis that they were defined by circumstance) the addition of a timing element in the Regulation took the category of Pt 4 claims covered out of the notion of a class. He accepted that on this analysis a regulation excluding Pt 4 simpliciter would be good, but one excluding the Part only from a particular point in time was bad. This is an outcome which exposes, in my view, the proposition as being unsustainable both in logic and on policy grounds.
