The Sewel convention and Brexit

mcewen-e1527685912390In March, the Constitution Unit co-published a new report, Parliament and Brexit, in which some of the UK’s leading academics examine how parliament has managed Brexit to date, and how it might seek to handle the issue in future. Here, Nicola McEwen discusses how the Sewel convention, which regulates the relationship between the UK Parliament and its devolved counterparts, was put under strain by Brexit.

There are four legislatures in the UK, but only one of these is sovereign. The sovereignty of the Westminster parliament remains one of the most important principles of the UK constitution. Each of the devolution statutes made clear that conferral of law-making powers on the devolved institutions ‘does not affect the power of the Parliament of the United Kingdom to make laws’ for Scotland, Northern Ireland and Wales – including in areas of devolved competence. But Westminster’s parliamentary sovereignty is offset by the constitutional convention that it will not normally legislate in areas of devolved competence, or alter the competences of the devolved institutions, without their consent.

That convention, commonly known as the Sewel convention, has become an important principle underpinning UK devolution. It represents a tacit understanding that the devolved institutions, each of which was founded on popular consent in a referendum, have primary democratic and political authority over laws within their areas of competence.

From the outset, the scope of the Sewel convention was ambiguous. The UK and devolved governments have frequently disagreed on the extent to which UK legislation necessitates legislative consent from the devolved institutions. When tasked with determining its status following its inclusion in the Scotland Act 2016 and the Wales Act 2017, the Supreme Court in Miller I concluded that it remained a convention rather than a legal rule, therefore ‘the policing of its scope and the manner of its operation does not lie within the constitutional remit of the judiciary’. The Court thus left it to politicians and parliament to determine the operation and interpretation of the convention. Continue reading

Politics, courts and the UK’s single market

image_preview.jpgBrexit is likely to pose numerous legal questions about how the various parts of the UK relate to each other once the UK leaves the EU. Deborah Mabbett argues that the recent Supreme Court decision on prorogation is therefore unlikely to be the last time the judiciary is called upon to decide a matter related to Brexit.

Even among those who welcomed the Supreme Court’s decision on the prorogation of parliament, there has been concern that it has entered into dangerous new territory. It might have been forced there by a Prime Minister who failed to observe convention, or by a parliament that resiled from its duty to remove a government which has no majority, but forced it was, and this is a source of concern and regret. Several commentators have argued that the decision paves the way for a nasty and unpredictable election structured around a populist opposition of courts and parliament versus ‘The People’, and indeed those who see Dominic Cummings as an evil genius fear that this was the intention of the prorogation in the first place.

For those seeking a calmer view, the Court is clear in its self-assessment that, far from entering new territory, it is firmly placed on ground it has held all along. It has upheld the rule of law, in the specific sense of imposing limitations on arbitrary authority. This is the daily bread and butter of administrative law, of which there is a great deal more than excitable commentators seem to realise. Below the public gaze, the courts have dug in their heels over countless daily exercises of executive power, including the mistreatment of immigrants, the removal of welfare rights and the denial of access to justice. True, the arbitrary power challenged in these cases is not exercised by the contemporary king—the Prime Minister—but by the agents and minions of the state. Escalating the level of scrutiny to the actions of high political figures makes the prorogation decision a matter of constitutional rather than administrative law, but law it is.

On what grounds can it be claimed that the Supreme Court’s decision is ‘political’? The domains of law and politics cannot be defined by their subject matter, which clearly overlap across great swathes of social issues. We must look instead for differences in method and modes of reasoning. The characteristic method of politics is the structured antagonism of government and opposition, organised around the general political orientations of left and right. The belief that the Court had made this kind of decision seems to be behind the claim of Toby Young and Douglas Carswell, among others, that the prorogation judgment calls for action to ferret out and expose the partisan leanings of the justices. Yet left and right partisanship was obviously beside the point in the decision. Continue reading

Is Tory unionism the greatest obstacle to Brexit?

image_normalAs the Brexit process continues, the Conservative Party is finding it hard to reconcile its desire to leave the EU with its longstanding commitment to maintaining the territorial and political union of the United Kingdom. Michael Kenny argues that, far from introducing a destabilising element to an otherwise sound constitutional set-up, Brexit has instead amplified and accelerated the debate about the UK’s territorial constitution.

‘I didn’t know it would break the United Kingdom’. This regretful rumination from columnist Peter Oborne – in a fascinating interview given in the wake of the recanting of his support for Brexit – touches on one of the key developments in the Brexit story. This is the gathering realisation in some Conservative circles that leaving the EU may well be incompatible with one of the foundational values of the Conservative party – the preservation of the integrity of the United Kingdom.

The painful discovery that these two goals are very hard – and maybe impossible – to reconcile is one of the great under-estimated political ironies of Brexit. For it has been those calling for the UK’s departure from the EU who have talked most confidently and directly about the distinctive character of Britain’s model of parliamentary sovereignty and the territorially differentiated unity expressed in in its constitutional arrangements. And whilst anxieties about whether Brexit might reignite the independence cause in Scotland were aired in the campaign leading up to the 2016 referendum, for the most part these remained at its margins.

But Prime Minister Theresa May has sounded a more anxious note ever since she entered office in July 2016. She has repeatedly – and a little mechanically – invoked the importance to her own politics of ‘our precious union’, a mantra that betrays a telling worry about the implications of a vote which accentuates a growing sense of political differences across the different nations and peoples contained with it, and also signals the salience in her own mind of the question of what implementing Brexit means for the domestic union.

Beyond Brexit: Towards a British Constitution

vb_image_70x90Brexit is a major constitutional change. It creates considerable constitutional uncertainty, but also opportunity. It could prove Britain’s constitutional moment. Vernon Bogdanor argues that just as joining the EU fundamentally altered the UK constitution, so Brexit could, by exposing the very nakedness of Britain’s uncodified arrangements, prove a catalyst for a written constitution.

During the period of membership of the European Communities/European Union, the UK was subject to a written or codified constitution, which was entrenched. Brexit is a process rare if not unique in the modern world, involving as it does disengagement from a codified to an uncodified system. It is just possible indeed that Brexit will lead to a codified constitution for the United Kingdom that would bring us into line with virtually every other democracy in the modern world.

At a seminar at King’s College, London shortly after the 2016 EU referendum, Takis Tridimas, a professor of European Law at King’s said that the result represented the most significant constitutional event in the UK since the restoration of the monarchy in 1660, since it showed that on the issue of Europe, the sovereignty of the people trumped the sovereignty of Parliament. Of course, from a legal point of view, the referendum was merely advisory, but the government committed itself to respecting the result and the outcome was seen by the majority of MPs as decisive. Since June 2016, therefore, both government and parliament have been enacting a policy to which they are opposed. That is a situation unprecedented in our long constitutional history. Europe, therefore, has been responsible for the introduction of a new concept into the UK constitution, the sovereignty of the people. On this issue, the people have in effect become a third chamber of Parliament, issuing instructions to the other two. The sovereignty of Parliament is now being constrained not by Brussels, but by the people.

The effects of the European Communities Act on the UK constitution

The main constitutional consequence of our EU membership was to restrict the sovereignty of parliament. Parliamentary sovereignty must be distinguished from national sovereignty, with which it is often confused. National sovereignty is engaged whenever a country signs a treaty. It is not an absolute, it can be pooled or shared with other countries, and it is a matter of political judgement how far it should in fact be shared. But parliamentary sovereignty – the notion that Parliament can enact any law it chooses – is not like that at all. It is an absolute. One either has it or one does not. One can no more be a qualified sovereign than one can be a qualified virgin. Continue reading
