Less than a decade ago, the High Court said, in effect, that State Supreme Courts have substantially the same entrenched jurisdiction to issue relief in the nature of the prerogative writs as the Constitution confers on the High Court. The New South Wales Court of Appeal reads this narrowly, holding that only three specific remedies are protected, together with the rules and limitations that existed at federation. If correct, we might see the emergence of two bodies of doctrine, the old law of remedies and the new law of ‘judicial review’ (a concept that emerged only after federation). In an unrelated case, six High Court judges implied a limited privative clause ousting non-jurisdictional certiorari. The seventh judge said that this was unnecessary, because in his view, that branch of certiorari conflicts with judicial review fundamentals, is historically misconceived, and should apply only where the reviewing court can try the matter afresh. This article reviews these developments, discusses their rationales and questions both the history and its importance.

23. In the course of a two-day long parliamentary debate on the British government’s foreign policy towards Russia and its allies, each side accused the other of moral and strategic failure between the wars. Churchill acknowledged those failures, but added that it would be more productive not to dwell on them: ‘For my part, I consider that it will be found much better by all [political] parties to leave the past to history, especially as I propose to write that history myself.’ United Kingdom, Parliamentary Debates, House of Commons, 23 January 1948, vol 446, col 557 (Winston Churchill).

30. The modern origins of mandamus are generally traced back to Bagg’s Case (1615) 11 Co 93b, 77 ER 1271; 1 Rolle 224, 81 ER 448. The advantage of using Coke’s account as reprinted in the English Reports is that it is in English with mostly modernised spellings. Historians might be dubious, however. Some of Coke’s contemporaries accused him of gilding the lily. A footnote at Bagg’s Case 81 ER 448, 1278 records Lord Ellesmere’s scathing response to Coke’s claim that King’s Bench had resolved that it had power to correct ‘any manner of misgovernment’. Ellesmere said that this would give issues of government to the court. Henderson said that only Coke could have succeeded in inventing such a wide-ranging remedy out of whole cloth: Henderson, above n 26, 68.

42. It is easier with hindsight to see Anisminic Ltd v Foreign Compensation Commission [1969] 2 AC 147, 171 (‘Anisminic’) as the principal marker for this development. The High Court’s decision in Craig v South Australia (1995) 184 CLR 163, 179–80 repeated Anisminic’s list of judicial review grounds, but said that prima facie, the same mistakes were non-jurisdictional if committed by inferior courts. That qualification was probably intended only for courts in the strict sense of that term. Even so, it was a variable quantity, becoming even more context-dependent since Kirk (2010) 239 CLR 531, 572–4. See also Mark Aronson, Matthew Groves and Greg Weeks, Judicial Review of Administrative Action and Government Liability (Thomson Reuters, 6th ed, 2016) 231–4.
43. That was critical to the reasoning in Anisminic [1969] 2 AC 147. The High Court officially rejected the narrow conception of ‘jurisdiction’ (whereby a decision-maker in an inquiry that had commenced properly could not thereafter ‘lose’ jurisdiction) in Kirk (2010) 239 CLR 531, 569–70. In fact, however, with only a handful of exceptions, the vast bulk of appellate decisions in Australia and England had failed to conform to that narrow conception since the 1930s.

47. England accepts that a detention that is invalid for judicial review purposes is also invalid for tort purposes, but awards only nominal damages at common law to claimants who ‘lost nothing’ because the government would have secured their detention lawfully if it had known of (and avoided) the flaw in the original detention process: R (Lumba) v Secretary of State for the Home Department [2012] 1 AC 245; R (Kaiyam) v Secretary of State for Justice [2015] AC 1344; R (O) v Secretary of State for the Home Department [2016] 1 WLR 1717. The Full Court of the Federal Court took that approach in Fernando v Commonwealth (2014) 231 FCR 251 (‘Fernando’), but views were divided in the High Court in CPCF v Minister for Immigration and Border Protection (2015) 255 CLR 514, 610–11 [324]–[325], 655–6 (Kiefel and Keane JJ, respectively, indicating approval of Lumba), 569 [155] (Hayne and Bell JJ indicating disapproval). For cases since Fernando taking essentially the same line, see: Okwume v Commonwealth [2016] FCA 1252; Guo v Commonwealth (2017) 258 FCR 31; Lewis v Australian Capital Territory (2018) 329 FLR 267. Tulloh v Chief Executive Officer, Department of Corrective Services [2018] WASC 105 avoided even nominal damages, by reasoning that legality of the plaintiff’s re-imprisonment turned on the fact of the cancellation of his parole, rather than on the legality of that cancellation.
48. See Rubinstein, above n 27, ch 4, distinguishing between tort actions (governed by the rule in the Case of the Marshalsea (1612) 10 Co Rep 68b) and certiorari. By mid-way through the 17th century, certiorari resembled the writ of error in that it went for any error of law apparent on the face of the record. Certiorari originally issued only against courts of record, but that was extended to include any inferior courts.
49. Writs of privilege issuing out of King’s Bench were formerly used to assert that court’s pre-eminence over the process and powers of other courts, but those writs appear to have been tied to the protection of King’s Bench officers, its process or its exclusive jurisdiction: Henderson, above n 26, 51–8.

The joint judgment said (581) that had he got in early enough, the applicant could have obtained prohibition. Brennan J added (594–5) that such an applicant could also have obtained an injunction.
54. Public Service Board (NSW) v Osmond (1986) 159 CLR 656. In contrast, the common law obliges judges to give reasons: Wainohu v New South Wales (2011) 243 CLR 181.

74. See Anisminic [1969] 2 AC 147, 171, 199, 200. That case discussed dozens of precedents, but overturned only one, namely Davies v Price [1958] 1 WLR 434, which had applied the view that jurisdiction cannot be ‘lost’ by errors committed in the course of a matter properly commenced.

76. Probuild (2018) 351 ALR 225, 256 [107]. His Honour repeated this viewpoint in Plaintiff M174/2016 v Minister for Immigration and Border Protection (2018) 353 ALR 600, 622 [94].
77. Henderson, above n 26, ch 4.
78. Rubinstein, above n 27, 72–3.
79. Henderson thought that whatever the courts may have said, their decisions failed to conform to any settled concept of ‘jurisdiction’ until R v Bolton (1841) 113 ER 1054, 1057. Essentially the same position is taken in Philip Murray, ‘Process, Substance and the History of Error of Law Review’ in John Bell et al (eds), Public Law Adjudication in Common Law Systems: Process and Substance (Hart Publishing, 2016), 95–101.

85. These were Platz v Osborne (1943) 68 CLR 133, 148 (‘Platz’); and Overseers of the Poor of Walsall v London and North Western Railway Co (1878) 4 App Cas 30, 44 (‘Walsall’). The statutory form of appeal in Platz allowed fresh evidence, and the only issue was whether a principle against double jeopardy prevented remittal for retrial. The passage to which his Honour referred related to the options open after resolution of a case stated. Walsall usefully documents the use of certiorari as an equivalent of case stated in the days before there was a general right of appeal in criminal matters; it said that quarter sessions could not resume hearing a matter if their order was quashed. It did not say that the matter could not be re-commenced; indeed, that is the general tenor of the Walsall judgments.
86. His Honour cited Ex parte Mullen; Re Hood (1935) 35 SR (NSW) 289, 301–2 (‘Mullen’). With respect, this is unconvincing; the entire debate in Mullen (and on its appeal to the High Court in Mullen v Hood (1935) 54 CLR 35) concerned jurisdictional error. His Honour also cited Mullen at 295–6, where Jordan CJ had indeed said by way of obiter that non-jurisdictional certiorari would issue only if the matter could be tried in the issuing court. Jordan CJ cited two respected secondary sources whose view, it is submitted, was equally unconvincing.
87. A more recent decision of the High Court bears out this proposition: Hossain v Minister for Immigration and Border Protection (2018) 359 ALR 1.
88. See, eg, A-G (Cth) v Alinta Ltd (2008) 233 CLR 542, 552 [10], 560 [37].

94. Statutory delegations of rule-making powers are said (with some justification) to lack the constitutionally requisite ‘intelligible principles’, a requirement prescribed by JW Hampton Jr & Co v United States, 276 US 394, 409 (1928) as America’s functional equivalent of Victorian Stevedoring and General Contracting Co Pty Ltd v Dignan (1931) 46 CLR 73.
95. Executive Order 13777 82 FR 12285 (24 February 2017) directs agencies to search for Rules that are too costly in a number of ways, so that they may be marked for repeal or reform. It introduces a revised and more focused reporting hierarchy.

100. Some of the reviews of Philip Hamburger, Is Administrative Law Unlawful? (University of Chicago Press, 2014) are beyond ‘heated’.

For something more civil (and generally supportive), see Gary Lawson, ‘The Return of the King: the Unsavory Origins of Administrative Law’ (2015) 93 Texas Law Review 1521. For more measured defences of the administrative state, see: Gillian E Metzger, ‘Foreword: 1930s Redux: the Administrative State Under Siege’ (2017) 131 Harvard Law Review 1; Cass R Sunstein and Adrian Vermeule, ‘The Morality of Administrative Law’ (2018) 131 Harvard Law Review 1924.
