This article shall examine a discrete, though somewhat overlooked, aspect of the relationship between the Commonwealth Parliament and the federal, or ‘Chapter III’, courts which emerges in the scenario where Parliament purports to amend the law that the courts are required to apply in pending cases. This is of particular significance where the Commonwealth is a party to the proceedings, given the obvious advantage to the Commonwealth, as litigant, provided by its power to legislate, and potentially to do so strategically to effect a desirable outcome. This raises the spectre of a significant separation of powers issue. This article will explore the extent to which this principle entrenched as law in the Australian Constitution has been able to limit Parliament's power to protect the independence of the federal courts to interpret and apply the law in an individual adjudication; that is, to protect their ‘decisional independence.’ Its success or otherwise is one measure of the extent to which the separation of powers, as a legal rule, is capable of protecting the independent adjudication of legal disputes by the courts from the vicissitudes of political power and influence.
The author acknowledges the valuable comments of Professor George Winterton on reading this article in draft.
1 Or where any Commonwealth agency, or any entity in which the Commonwealth has an interest, is a party.
2 Hereinafter referred to as 'the separation principle'. See R v Kirby; Ex Parte Boilermakers Society of Australia (1956) 94 CLR 254 ('Boilermakers'); aff'd sub nom Attorney-General for Australia v The Queen [1957] AC 288. The legal entrenchment in the Australian Constitution was inferred from the separate vesting of the executive, legislative and judicial powers pursuant to ss 1, 61 and 71. See Leslie, Zines, The High Court and the Constitution (4th ed, 1997), Chapter 10Google Scholar.
3 The phrase was coined by Martin, Redish in 'Federal Judicial Independence: Constitutional and Political Perspectives' (1995) 46 Mercer Law Review 697Google Scholar. He defined it as 'the ability of the federal courts to interpret and apply... substantive legal principles in the specific context of an individual adjudication, free from control or interference by the purely political branches of the federal government.'

6 The term derives from American commentary on similar legal principles developed by the United States Supreme Court. The principle has been long established in United States jurisprudence, originally stated in United States v Schooner Peggy, 5 US (1 Cranch) 103 (1801).

The simple rule would seem to be that, just as the legislature cannot directly reverse the judgment of the court, so it cannot, by a declaratory law, affect the rights of the parties in whose case the judgment was given … That is to say, the legislature may overrule a decision, though it may not reverse it; it may declare the rule of law to be different from what the courts have adjudged it to be, and may give a retrospective operation to its declaration, except so far as the rights of parties to a judicial decision are concerned … In other words, the sound rule of legislation, that the fruits of victory ought not to be snatched from a successful litigant, is elevated into a constitutional requirement.

46 As a preliminary step, the Privy Council dealt at some length with the issue of whether the separation principle was legally incorporated in the Ceylonese Constitution and held that it was. This it regarded as a prerequisite to its jurisdiction to invalidate the legislation on separation of powers grounds: Ibid 283ff. See T R S Allan, Law, Liberty, and Justice; The Legal Foundations of British Constitutionalism (1993) who argued (at 69ff) that the decision could stand without the need to establish as a prerequisite the legal incorporation of the doctrine in the constitution. He stated this in support of his broader thesis that the United Kingdom Parliament is bound by the separation principle to limit judicial interference even though it has an unwritten constitution. Such alternate basis for the doctrine's legal force is discussed in Liyange, ibid, 283 ff.

101 It should be noted that Kirby P also dismissed as irrelevant a whole host of legislation cited by the Minister which interfered with the judicial process, but remained on the statute books , saying that '[t]he fact that error has been oft repeated does not make it less an error. The failure of other litigants, perhaps with less at stake, to challenge the intrusion of the Parliament into matters before the courts does not relieve the Court of evaluating the challenge once made': ibid 392. Having made the above observations, concluding that there was indeed an interference with judicial process, he was unable to invalidate the legislation because there was no legal separation of powers in the New South Wales Constitution: ibid 394.

112 The majority in relation to the s 54R issue consisted of Brennan, Deane, Dawson JJ (in a joint judgment) and Gaudron J in a separate judgment. It should be noted that the majority first examined the impugned provisions from the point of view of classic Boilermaker's principles, stating (ibid 26-7) that the judicial power of the Commonwealth could not be conferred upon any organ of the Executive, nor was the legislature permitted to enact a law which 'requires or authorises the courts in which the judicial power of Commonwealth is exclusively vested to exercise judicial power in a manner which is inconsistent with the essential character of a court or with the nature of judicial power'. As a consequence, the separation principle created a constitutional immunity from being imprisoned except pursuant to an order by a court in the exercise of the judicial power of the Commonwealth, subject to some very important exceptions such as detention pending trial, or in the case of infectious diseases or mental illness (ibid 129, although see Gaudron J's reservations at 55). This aspect of the judgments, although of great significance, is not presently relevant and the article shall only discuss the Court's treatment of legislative interference with judicial functions.

129 Subsequent to Lim, the High Court in Leeth v Commonwealth (1992) 174 CLR 455 also confirmed in obiter that the developments in relation to the issue of legislative interference had been recognised by the court. It was regarded as a particular type of usurpation of judicial power by Mason CJ, Dawson and McHugh JJ:
[L]egislation may amount to a usurpation of judicial power, particularly in a criminal case, if it prejudges an issue with respect to a particular individual and requires a court to exercise its function accordingly (see Liyanage v The Queen). It is upon this principle that bills of attainder may offend against the separation of judicial power (see Polyukhovich v Commonwealth). But a law of general application which seeks in some respect to govern the exercise of a jurisdiction which it confers does not trespass upon the judicial function.' (at 469-70).

151 They nevertheless confirmed that the central attributes relevant to the present enquiry were that the judicial power consisted of the exercise of that power required for the resolution of controversies between citizens or between citizens and the Crown, which resolution was a binding and authoritative decision based on the determination of existing rights and duties according to law. See the oft-quoted standard definitions in Huddart Parker and Co Pty Ltd v Moorehead (1909) 8 CLR 330, 357 (Griffith CJ), Fencott v Muller (1983) 152 CLR 570, 608.
152 Kirby J, in particular, queried whether any valuable assistance could be derived from a precise definition, in the present enquiry: '[S]uch generalities give scant guidance when, as here, a particular statutory provision is challenged and is said to be an impermissible legislative intrusion upon, or derogation from, the judicial power.'

Almost certainly, only five individuals are involved. The fact must therefore be faced that this is very special legislation addressed to the courts directly affecting five or so particular persons already charged and awaiting trial in those courts. In their cases, and theirs alone, the law governing their pending trials has been changed in a way that seriously affects them.

207 (1998) 195 CLR 547. It should be noted that this case involved State legislation and proceedings of a State court. The reason Chapter III of the Constitution arose at all was as a result of Kable's case (above n 70) which held that State Parliaments are constrained in legislating in relation to their courts because they are part of an integrated system of State and federal courts invested, under s 77(iii) of the Constitution, with federal, as well as State jurisdiction. Hence, State Parliaments may not vest functions incompatible with the operation of State courts as repositories of federal judicial power.
