Mr Johnson’s claim that the suspension was a routine break before a new legislative session stands exposed. The judges found the prime minister in effect misled MPs, the British people, and the Queen. No future premier will be able to act this way again. The judges’ ruling marks a historic moment in the evolution of the UK constitution.
The court’s decision was a much-needed reminder that, even in the most testing political circumstances, Britain remains a representative democracy underpinned by the rule of law. MPs are elected to exercise their good judgment and take decisions on behalf of constituents. They hold to account a government formed from among their number. The executive is accountable to parliament, and parliament to the people. Removing parliament, even for a matter of weeks, breaks the chain of accountability. The UK system cannot allow a cabal around the prime minister to determine by itself the “will of the people” and attempt to implement it, while sidelining those whom the people elected to represent them. This is the road to tyranny.

The power to suspend parliament, the judges found, is limited if it conflicts with parliament’s sovereign power to make laws, and the government’s accountability to parliament. Prorogation is unlawful if its effect prevents parliament from fulfilling its functions — without a very good reason. In one of the most stinging passages of their ruling, the judges found the effect of Mr Johnson’s actions on British democracy was “extreme”, and that the government had put forward no proper justification.
