In R. (Miller) v Secretary of State for Exiting the European Union, the Supreme Court of the UK (1) held that the UK Government had no prerogative power to initiate the formal process whereby the UK will withdraw from the EU and (2) declined to recognise any requirement that the devolved legislatures’ consent be obtained in respect of legislation authorising the Government to commence the withdrawal process. This article critically examines Miller, arguing that the majority's analysis veers between unwarranted muscularity in relation to the prerogative issue and unnecessary conservatism as regards the devolution issue. The article goes on to argue that while the majority judgment's restrictive approach to the prerogative may be viewed as a progressive victory for constitutional principle, such an evaluation can be sustained only if a set of relatively traditional constitutional premises are adopted to begin with. The article also contends that the general approach adopted by the majority is problematic, given its willingness to invoke arguments of constitutional principle without adequately engaging with questions about what the pertinent principles are, and argues that such an intellectually lackadaisical mode of constitutional adjudication is to be deprecated.

2 The majority consisted of Lord Neuberger, Lady Hale, Lord Mance, Lord Kerr, Lord Clarke, Lord Wilson, Lord Sumption and Lord Hodge. Lord Reed, Lord Carnwath and Lord Hughes dissented.

7 See Section V below. In the principal dissenting judgment, Lord Reed concluded that the argument based on convention did not, on his analysis, arise, because, on his view, no legislation to which devolved consent could be given was required: Miller [2017] UKSC 5; [2017] 2 W.L.R. 583, at [177].

10 Although the question of revocability might seem to be key, it is at least arguable that it is a red herring. As G. Peretz, “Will the Supreme Court Have to Make a Reference to the Court of Justice of the EU in Miller? Further Thoughts”, Monckton Chambers Brexit Blog, 14 November 2016, argues, even if Parliament could intervene to prevent an Article 50 notification from resulting in Brexit, the fundamental principle remains that “the Royal Prerogative should not be able to remove statutory rights without a positive act by Parliament, namely a specific statutory power or an Act of Parliament”. On this analysis, even if the Article 50 notification were unilaterally revocable by the UK, that would not impact upon the question whether legislation is needed to authorise the initiation of the withdrawal process.

20 Lord Reed's is the leading dissenting judgment in the sense that it, unlike any other dissenting judgment, commanded the support of all the other dissentients.

34 It is possible to read the majority judgment, at least in places, even more broadly, i.e. as suggesting that the scale argument does not (simply) bear upon questions about how the ECA should be construed, but operates instead as an independent and direct constraint upon the use of prerogative power.
35 Miller [2017] UKSC 5; [2017] 2 W.L.R. 583, at [82]. The view that “fundamental” constitutional changes can be made only by Parliament has something in common with the position adopted by the Court of Appeal in R. (Jackson) v Attorney General [2005] EWCA Civ 126; [2005] Q.B. 579, in which it was said (at [48]) that certain fundamental changes “could only be enacted or expressly made possible by what is traditionally the sovereign Parliament” rather than under the Parliament Acts 1911–49. However, the House of Lords went on to reject the distinction that the Court of Appeal had sought to draw between fundamental and other constitutional changes: R. (Jackson) v Attorney General [2005] UKHL 56; [2006] 1 A.C. 262.

40 For a contrasting analysis, according to which the HRA creates “statutory rights” such that withdrawal from the ECHR would not terminate the HRA's capacity to protect convention rights, see E. Bjorge, “EU Rights as British Rights”, University of Bristol Law School Blog, 14 November 2016. My present purpose is not to assess the merits of these two analyses. Rather, it is to consider whether Miller tells again a reading of the HRA that leaves open the possibility of prerogative-instigated withdrawal from the ECHR.
41 Indeed, the HRA explicitly eschews any such claim: legislation, including Acts of the UK Parliament, that are found to be incompatible with convention rights can be declared to be so under s. 4(2), but such a declaration, according to s. 4(6), “does not affect the validity, continuing operation or enforcement of the provision in respect of which it is given”.

52 I am not concerned here with EU law that secures legal effect in the UK through the enactment of domestic legislation (e.g. secondary legislation made under the ECA, s. 2(2)). When such domestic legislation is enacted, it is that legislation and not the EU instrument that prefigured its enactment, that has domestic legal effect. In such circumstances, there is no question of EU law constituting domestic law; rather, EU law is the proximate cause of the enactment of law that is, uncontroversially and in the full sense, domestic law.
