The spirit or equity of a statute
15 The submission by counsel for Mr Burragubba would not have raised many eyebrows in the 17th or 18th centuries. At that time, the idea that a court could depart from the express and implied words of a statute was widely recognised. A famous exposition of it was the decision of Lord Mansfield in Simon v Motivos (1746) 1 Black W 599, 600; 96 ER 347, 347. In that case, Lord Mansfield suggested that the provisions of the Statute of Frauds 1677 might not apply to a sale by auction. Although there was no basis in the legislation for this exclusion as an implication, Lord Mansfield said that the "key" to construction of the Statute of Frauds was "the intent of the Legislature; and therefore many cases, though seemingly within the letter, have been let out of it". Blackstone, who reported this decision, explained in his Commentaries that there are two limbs to the doctrine of the equity of the statute: "[1] cases, thus out of the letter, are often said to be within the equity... [2] cases within the letter are frequently out of the equity": Blackstone, W Commentaries on the Laws of England (4th ed, Kerr R (ed), 1876) 223. The same point was made by St Germain, Viner, Bacon, Coke and Wood.
16 The doctrine was always controversial. One difficulty with it was that it contravenes the principle of legislation, of which Barwick CJ spoke in Watson v Lee [1979] HCA 53; (1979) 144 CLR 374, 381, that a person should not be bound by a law the terms of which she has no means of knowing. Another difficulty, which was recognised with the rise of parliamentary sovereignty, was that the doctrine crossed the line of constitutional settlement between adjudication and legislation. Although the line between legislation and adjudication might sometimes be very difficult to discern, it was said to be legislation, not adjudication, for a judge to derive from a statute a rule which was neither expressed nor implied in the statute and which might be contrary to the terms of the statute. As Deane and Gummow JJ observed in Nelson v Nelson [1995] HCA 25; (1995) 184 CLR 538, 553, the doctrine of the equity of the statute "fell deeply into disfavour in England and the United States with the rise of legal positivism in the last century". By the mid-19th century, Sedgwick remarked of the second limb of the equity of the statute in The Interpretation and Application of Statutory and Constitutional Law (1857) 306-307:
There is no propriety in calling the process, construction or interpretation. It consists in inserting a clause, to provide for a class of cases which the court thinks ought, as a matter of justice, to be excepted out of the statute. Nor is there any ground for asserting, that if the subject had been called to the attention of the legislator he would have made the exception. … The process, therefore, in these cases, is not obedience to legislative commands; it is not an effort to arrive at the legislative intention; it is not construction of a doubtful provision it is a violation of the words of the statute, in order to make a rule according to the judicial notion of right. It is purely and strictly judicial legislation. And, fortunately, we are not without abundant authorities in our law which steadily, it may be sternly applied, will establish in its proper place the line that separates the judicial from the legislative functions.
17 The doctrine today remains controversial. It is hard to see how it can have any substantive operation in the form in which it originated. The High Court has emphasised that the task of statutory construction begins and ends with the meaning of the statutory text: Commissioner of Taxation v Consolidated Media Holdings Ltd [2012] HCA 55; (2013) 250 CLR 503, 519 [39] (the Court). It is no longer legitimate to speak, as Plowden did in his note to Eystone v Studd (1574) 2 Plow 459, 465-469; 75 ER 688, 695-700, of a general power for "the general words of the law [statute]" to be "corrected and abridged by equity".
18 However, there remain limited examples where Courts still apply an approach to give a statute a meaning which the words cannot literally bear. One example is the correction of "simple, grammatical, drafting errors which if uncorrected would defeat the object of the provision": Taylor v Owners - Strata Plan No 11564 [2014] HCA 9; (2014) 88 ALJR 473, 483 [38] (French CJ, Crennan and Bell JJ). An instance commonly cited is French legislation that, read literally, would have made it an offence for passengers to get on or off a train when the train was not moving. The correction of such a "thumping, obvious error" is usually explained as involving an "implication" or as a "contextual" approach to the meaning of the statute: Siegel, JR "What statutory drafting errors teach us about statutory interpretation" (2001) 69 George Washington Law Review 309. It does not matter whether these examples are described as applications of a weaker version of the equity of the statute, or as implications, or as contextual construction. In each case, unlike other instances involving the equity of the statute, these rare examples are nevertheless consistent with constitutional divisions of power.
19 Another example, which might be a progeny of the first limb of the equity of the statute, is the role of statute in developing the common law. In Esso Australia Resources v Commissioner of Taxation [1999] HCA 67; (1999) 201 CLR 49, 62 [24], Gleeson CJ, Gaudron and Gummow JJ quoted with approval from Lord Diplock in Warnink v J Townend & Sons (Hull) Ltd [1979] AC 731,743, albeit noting the context of a nation with a single Parliament:
Where over a period of years there can be discerned a steady trend in legislation which reflects the view of successive Parliaments as to what the public interest demands in a particular field of law, development of the common law in that part of the same field which has been left to it ought to proceed upon a parallel rather than a diverging course.
20 An application of this approach differs from the form and style of reasoning in many of the older cases involving the equity of the statute. It does not purport to be an application of the statute to the facts of a case. Rather, it is a legitimate recognition that the common law has always been developed, incrementally, by reference to underlying, and structural, norms and principles. The existence of uniform Australian legislation on a subject is undoubtedly a potential source of such structural societal norms.
21 Nevertheless, caution should be applied before identifying some underlying norm in uniform legislation which is capable of general application to develop the common law. The need for caution arises because the statute has not itself extended to that area of common law. It may be that the legislative intention, revealed by the terms of the statute, involved a positive decision to create a rule of limited application rather than one supporting a new underlying norm capable of general application.
22 This concept of development of the common law by underlying statutory norms should also apply to instances involving other statutory discretions which are relatively unconstrained and have been developed, incrementally, by the common law method. Although the submissions of counsel for Mr Burragubba were expressed in the language of the "equity" or "spirit" of s 85A of the Native Title Act, it is in this limited sense in which those submissions should be understood. In other words, Mr Burragubba's submission should be understood as asserting that an underlying norm created by s 85A of the Native Title Act should be applied beyond the strict terms of that statute to develop the manner in which a costs discretion under the Federal Court Act is exercised.
