Brexit: Illuminating Weaknesses in the British Constitution

The 2016 Brexit referendum and the events that followed put pressure on the UK’s Constitutional structure. Ministerial decisions to prorogue parliament as well as their interpretation of conventions during the process of Brexit has raised concerns and led to many questions surrounding the,

‘Peculiarly improvised nature of the UK Constitution’ (Weale, 2018)

What type of constitution does the UK have?

The UK is a known to have an uncodified constitution. Unlike other countries, the UK constitution is a combination of written and unwritten sources that have evolved over centuries. In the UK, parliament is sovereign; therefore, for the constitution to be upheld, it must continue to operate as a check and balance on other powers. These are the additional sources of the UK constitution, which when taken as a whole, help to build a constitution that can change and evolve alongside society.

  • Common Law (Developed through Judicial review)
  • Constitutional Conventions (Guiding behaviours of constitutional actors)
  • Royal Perogatives (Certain powers historically exercised by the Monarch, but are now handed to the Prime Minister)

Brexit, however, led to an imbalance of power between the sources of the constitution. The prorogation of parliament in 2019 resulted in the misuse of royal prerogatives, allowing the executive branch to exert excessive control over the interpretation of the constitution in order to manipulate the Brexit discussions according to their own preferences.The vagueness of the UK Constitution is essentially what made particular actions obtainable for politicians at the time.

What exactly showed weakness of the British Constitution:

On the 24th September 2019, the Supreme Court ruled that Boris Johnson’s decision to prorogue parliament for five weeks was “unlawful” and “unconstitutional”

‘The sovereignty of Parliament would, however, be undermined as the foundational principle of our constitution if the executive could, through the use of the prerogative, prevent Parliament from exercising its legislative authority for as long as it pleased.’ (Davis, 2019)

The House of Commons determined that reaching an agreement on a Withdrawal Deal with the EU during the Brexit negotiations was not feasible. The executive, challenged with creating and passing a withdrawal deal before the deadline on January 31st 2020, decided to suspend parliament for five weeks. For the Prime Minister to be able to silence parliament, it required the Queen to conform to advice given to her by her ministers, act on her Royal Perogatives, and close parliament.

The need for the Queen to maintain her impartiality and avoid becoming involved in politics has long been a cornerstone of the uncodified constitution of the United Kingdom. The Queen will tenaciously work to uphold that concept, but when her ministers formally advise her on matters of Royal prerogative – the executive powers that ministers exercise on her behalf – she depends on them to do the same.

Many have questioned whether our unwritten constitution is appropriate in light of the manipulation of traditional roles. If nation’s leaders have the chance to act “illegally,” and “frustrate the ability of parliament to carry out ins constitutional functions,’ then perhaps there should be formal guidelines on the distribution of power.

Why this has led to a desire for a written constitution?

As Andrew amble writes,

‘What is distinctive about British Politics is that its traditional constitution is increasingly a source of instability rather than stability.’ (Gamble, 2016)

Brexit has simply indicated that when governmental powers and procedures lack a written source, then it is susceptible to manipulation, often justified as new interpretation.

The UK’s recent political crises have been made worse by this ambiguity. For instance, the precise legal standing of referendums has never been established. Referendums have not historically been seen as part of the UK constitution; Clement Attlee famously called them “the instruments of Nazism and fascism” and “alien to our traditions.” (Peat, 2019)

Do referendums easily sit with the principle of parliamentary sovereignty?

The UK constitution has never firmly establish laws and procedures, as there had only been four referendums prior to 1997. Again, referendums were ambiguous, which only serves to confirm the theory that the difficulty of the Brexit negotiations was caused by a lack of unwritten rules.

To summarise:

The government’s attempt to negotiate an exit agreement from the EU revealed the flaws in the British constitution.

Because the constitution is unwritten, there are no rules, which resulted in ministerial decisions taken to limit the authority of parliament and interpreting the constitution generally to suit the executive branch’s goals in the event of a no-deal leave

Brexit demonstrated the ease with which the government may subvert the UK constitution, which is the text and customs that preserve democracy and rights.
