The parliamentary battle over Brexit and the constitution

Today sees the publication of a new book by the Unit’s Meg Russell and Lisa James, The Parliamentary Battle over Brexit. Here the authors summarise some of its key findings about why parliament was drawn into such controversy over the implementation of Brexit. They reflect on what these events teach us about our constitution, as well as what may need to change in order to avoid repeating such problems, and to mend the damage done.

The UK’s arguments over what became known as Brexit began long before the June 2016 referendum, and continued with increasing bitterness afterwards. Parliament was often central, both as a venue for such arguments, and in terms of disputes about its proper role. It and its members frequently faced criticism and blame. Our new book, published today, charts The Parliamentary Battle over Brexit, from the early pressures for a referendum, through disputes about the triggering of Article 50 and control of the House of Commons agenda, the repeated defeats of Theresa May’s deal, and Boris Johnson’s unlawful parliamentary prorogation, to the UK’s eventual departure from the EU following his deal. The book charts what happened, but also asks what went wrong and whether things could have been handled differently. It reflects on what these events teach us about the functioning of our constitution, and what if anything might need to change.

The book includes a wealth of detail about key political moments, and the roles of different individuals and groups. Here we focus on some of the bigger questions about the lasting legacy of the battles over Brexit for the culture and institutions of UK politics, and particularly for the place of parliament itself. A fuller version of this analysis appears in the final chapter of the book.

Referendums and public participation

The referendum of 23 June 2016 was only the third ever such UK-wide vote (the first being on European Community membership in 1975, and the second in 2011 on changing the House of Commons voting system). The handling of the referendum was the single biggest error of the Brexit process, from which many other difficulties flowed.

Unlike the 2011 referendum, which was underpinned by legislation setting out the detail of the proposed new voting system, no clear prospectus was offered to the voters for Brexit. Prime Minister David Cameron hoped to use the vote – described disapprovingly by the House of Commons Public Administration and Constitutional Affairs Committee as a ‘bluff call’ referendum – to make the question of Brexit go away. Parliament never debated the substance of the question, the government did not detail the options, and civil servants were forbidden from preparing for a Leave vote. Leave campaigners argued at the level of principle, rather than on a specific plan. As one Brexit-supporting interviewee told us, ‘it was only [after the referendum] that different types of Brexit started coming to the fore. Soft Brexit and hard Brexit had never been canvassed before the referendum; the expressions were coined afterwards’. Issues that would soon come to dominate the agenda, such as membership of the Customs Union or Single Market, and crucially the Northern Ireland border, were barely mentioned during the campaign. This left the government – and parliament – in a very difficult position. The different options for Brexit had to be established only after the vote had taken place, and on this the voters had conveyed no clear instruction.

Reliance on secondary legislation has resulted in significant problems: it is time to rethink how such laws are created

The legislative challenges posed by Brexit and the unusual circumstances of the pandemic have led to a significant increase in the use of secondary legislation. The former Head of the Government Legal Department, Jonathan Jones, argues that mass use of statutory instruments is problematic, and that there should be a fundamental rethink of how and when they are used, debated and approved. He calls for a new Statutory Instruments Act to enable this ‘reset’.

Brexit and the pandemic have led to an increase in secondary legislation

Both Brexit and the COVID-19 pandemic have seen the government making increased use of secondary (or subordinate) legislation. This is where ministers make law in the form of (usually) regulations contained in a statutory instrument (SI), under powers conferred by parliament in an earlier Act. It’s ‘secondary legislation’ by distinction with ‘primary legislation’ – Acts of Parliament.

It is easy to see why governments like secondary legislation. The process of making regulations is normally much quicker and easier for ministers than trying to pass a new Act each time.

Well over 600 SIs were made to give effect to Brexit – mainly to make sure that pre-existing EU law ‘worked’ in the UK once we had left the EU. Some of the changes were technical and minor, though others were much more substantial. In addition, ministers have made over 500 SIs to legislate in response to the pandemic – including imposing lockdowns, travel restrictions and the closure of businesses.

There is nothing inherently unconstitutional about this. Secondary legislation is an established part of our system of law-making. It is open to our sovereign parliament to confer whatever powers it wants on ministers, subject to whatever conditions, limitations and procedures it wishes to impose. And ministers are entitled to exercise those powers, subject to review by the courts.

Using regulations to prescribe technical or procedural detail, pursuant to policies and structures set out in Acts of Parliament, is normally unexceptionable and indeed sensible: it avoids parliament being clogged up with unnecessary mundane business. On the other hand, some of the powers conferred on ministers are very wide and go well beyond merely technical or procedural matters. COVID-19 regulations have been used to impose the most intrusive restrictions on all aspects of national life.

The Fixed-term Parliaments Act did not cause the Brexit impasse

Next week MPs debate the government’s bill to repeal the Fixed-term Parliaments Act 2011. One argument frequently deployed for scrapping the Act is that it generated gridlock over Brexit. But, Meg Russell argues, no clear counterfactual to support this claim has ever been presented. In fact, when considering the possible scenarios, it seems likely that the situation would have been made worse, not better, had the Prime Minister retained an untrammelled prerogative power to dissolve parliament in 2017–19.

Next week MPs debate the remaining stages of the Dissolution and Calling of Parliament Bill, which seeks to repeal the Fixed-term Parliaments Act 2011 (FTPA). It proposes to reinstate the pre-FTPA position, whereby the Prime Minister would effectively control general election timing using prerogative power. A key argument deployed by those seeking repeal of the FTPA is that it helped to cause the Brexit deadlock of 2019: that the FTPA, as the Conservative manifesto put it, ‘led to paralysis at a time the country needed decisive action’. But to what extent is this really true?

While suggestions that the FTPA created the Brexit deadlock are commonplace, most experts who contributed to the three parliamentary committees that have considered FTPA repeal (the Commons Public Administration and Constitutional Affairs Committee, Lords Constitution Committee and Joint Committee on the Fixed-term Parliaments Act) argued that the deadlock resulted from other factors. Most obvious were the post-2017 combination of a minority government, the need to deliver on a contested referendum result, and deep divisions within the governing party. These problems were clearly serious, and it is very far from clear that the FTPA could have resolved them.

A careful reading of the evidence presented to the three parliamentary committees, and of the Commons second reading debate on the bill, finds that most claims against the FTPA over Brexit are distinctly vague. No clear counterfactual is offered. This particularly applies to events during Theresa May’s premiership, when the most intractable problems arose. The situation did change in the autumn of 2019 under Boris Johnson (as discussed below), but the FTPA’s targeting as a causal factor dates back far earlier than this. Likewise, during interviews with a series of senior figures for a current book project on parliament and the Brexit process, I have asked several critics of the FTPA how, if Theresa May had been able to trigger an early general election without parliament’s consent, things would have turned out differently. I have yet to receive a convincing reply.

Five years of ‘EVEL’

In the wake of the devolution settlements of the Blair years, political pressure to answer the ‘West Lothian Question’ persisted. In 2015, the proposed answer was ‘English Votes for English Laws (or EVEL). Today, on its fifth anniversary, Daniel Gover and Michael Kenny assess how EVEL has worked, during one of the most volatile political periods in living memory.

On 23rd October 2015, the ‘English Votes for English Laws’ (or EVEL) procedures came into force in the House of Commons. Introduced by David Cameron in the aftermath of the Scottish independence referendum, these new rules were designed as an answer to the notorious ‘West Lothian Question’ – the late Tam Dalyell’s resonant enquiry about why Scottish, Welsh and Northern Irish MPs should continue to be able to vote on matters that only affected England after devolution, while MPs in England were not able to reciprocate in devolved areas.

When EVEL was introduced, the procedures were sharply criticised by opponents. For some, the reform would not only be logistically difficult to implement – likely to be ‘incomprehensible’ to MPs and the public alike – but would also threaten the UK’s constitutional makeup. In particular, it was argued that EVEL would establish ‘two classes of MP’ at Westminster, undermining the ability of non-English MPs to represent their constituents’ interests. Others, meanwhile, criticised the procedures as too tame, and falling short of providing adequate representation to England.

The five-year anniversary provides an opportune moment to review how this contentious reform has fared in practice. Yet the wider territorial politics of the UK have also undergone significant changes in the intervening period. The questions to which these complicated rules were a response have become ever more pressing, but whether EVEL can provide a sustainable response to the increasingly fraught question of English devolution is increasingly doubtful.

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
