Petra Schleiter and Thomas Fleming examine the power to prorogue parliament. They outline the legal basis of prorogation, survey how it is used in the UK and other Westminster systems, and discuss how the UK could reform its prorogation process.
The UK government has the power to suspend parliament, in a process known as prorogation. Prorogation is usually a routine measure, used to schedule gaps between sessions of parliament. But it became highly controversial in 2019, when the government tried to prorogue parliament for five weeks shortly before the scheduled Brexit date of 31 October. This decision caused uproar, and was ultimately quashed by the Supreme Court.
This controversy prompted discussion of whether the UK’s prorogation rules should be reformed. In particular, some have asked whether this power should be considered as part of the forthcoming review of the Fixed-term Parliaments Act 2011, which is legally required to take place this year. Here we outline the consequences of the current rules, showing that they are unusual, and suggesting possible ways for them to be reformed. Fuller versions of our arguments can be found in our recent articles in Political Quarterly and Parliamentary Affairs (forthcoming).
What are the consequences of the current prorogation rules?
Prorogation ends a parliamentary session. It means that neither House of Parliament may sit, and parliamentary business is almost entirely suspended. Though prorogation is formally a prerogative power of the monarch, she acts on the advice of the Prime Minister. In practice, therefore, the timing and length of prorogation are decided by the government. Parliament has no power to insist on sitting once it has been prorogued: only the government can shorten or prolong a prorogation. This situation makes it possible for the government to use prorogation for political purposes when its interests conflict with those of parliament.
