What is the prorogation of parliament?

Supreme Court says Boris Johnson’s decision to suspend Parliament was ‘unlawful’

Boris Johnson’s controversial prorogation of Parliament has been ruled “unlawful” by the Supreme Court.

The panel of 11 justices was unanimous in the decision, after listening to evidence on the legality of the prime minister’s advice to the Queen to suspend the House of Commons for five weeks.

They heard historic appeals that arose out of separate legal challenges in England and Scotland, which produced differing outcomes.

Johnson’s opponents argued that it was an “unlawful abuse of power” aimed at silencing MPs, while his lawyers tried to claim that the Supreme Court had no jurisdiction to rule on the length of prorogation.

Speaker John Bercow has said the House of Commons will resume at 11.30am on Wednesday.

So what is proroguing?

Prorogation is the formal term for the end of a parliamentary session and is marked with a ceremony in the House of Lords. It normally entails an announcement and speech on behalf of the Queen.

According to, once the Commons has been prorogued, all motions that have not been answered, or Bills that have not obtained Royal Assent, will not progress any further. Neither House can meet, debate and pass legislation.

A Bill can, however, be reintroduced in the next session by an MP or continue in the next session if a carry-over motion has been passed.

While prorogation is a normal process, the length of suspension in this case - from 9 September to 14 October - was deemed unusually long. Opponents feared the government was sending MPs away to stop them blocking the UK’s exit from the EU with or without a deal.

Johnson’s prorogation “does seem like a very obvious move to cut down the time available for anti-no-deal MPs to do something about it”, the Institute for Government’s Catherine Haddon told the BBC.

iNews adds that, “historically, this method has been used by monarchs to stop Parliament from interfering with their plans”.

What is the difference between prorogation and dissolution?

While proroguing happens at the end of every session, dissolution only occurs before an election.

Under the Fixed-term Parliaments Act, Parliament is dissolved 25 days before an election - but prorogation can predate that, and kill all the House’s business while Parliament technically still exists.

The BBC notes that the latest session had been going for two years - since the 2017 election - “as it was extended to tackle the legislation for Brexit”.

Prorogation is also different from a “recess”, when the House does not sit but parliamentary business can otherwise continue as usual.

Is there a precedent for this?

This sort of thing “makes officials rather nervous”, says Politico, although Theresa May’s former legislative adviser Nikki da Costa notes it has been done before.

Writing for The Daily Telegraph, she says: “This is not to be done lightly, but there is historical precedent. In 1948 a new Parliament Bill to reduce the power of the Lords was being blocked by peers, but powers… which would allow the government to override the Lords could only be used if there had been a delay over three ‘sessions’. A special short session of 10 days was therefore arranged.”

Reacting to Johnson’s plan to ask the Queen to suspend Parliament, Conservative Party Chairman James Cleverly defended the plan as something “all new governments do”.

Could the Queen have refused?

The Queen technically has the power to refuse the Government’s request to suspend Parliament, but constitutionally a refusal is impossible.

Under the British Parliamentary democracy, the Queen acts on the advice of her prime minister.

That means that decisions over when Parliament sits are decided by the Government, and only rubber-stamped by Buckingham Palace.

What did the Supreme Court rule?

Today, the Supreme Court justices said: “The decision to advise Her Majesty to prorogue was unlawful because it had the effect of frustrating or preventing the ability of parliament to carry out its constitutional functions.”

Therefore the prorogation is “void and of no effect”, meaning Parliament has not been suspended.

Over the weekend, Foreign Secretary Dominic Raab told the BBC’s Andrew Marr Show: “Of course we will respect whatever the legal ruling is from the Supreme Court.”

He added that there may be “different permutations as to what the Supreme Court may or may not decide” and that “later in the week we’ll obviously want to look at that very carefully”.

But today’s ruling was very clear.

“We expected constitutional history leading to legal and political tremors - we got an earthquake,” says Sky News home editor Jason Farrell. “The government has lost on all levels.”
