Title

Supreme Court rules Holyrood cannot legislate for an independence referendum

Date
23 November 2022 (judgment)

What happened?

The Scottish Government wanted to hold a second referendum on independence and drafted a bill for an advisory vote. The Lord Advocate, the Scottish Government’s senior law officer, asked the Supreme Court to decide whether the Scottish Parliament had the power to pass it.

The Court ruled unanimously that it did not, because a referendum on independence relates to matters reserved to the UK Parliament under the Scotland Act 1998.

Relevant factual details

  • VerifiedJudgment on 23 November 2022; a unanimous decision of five Justices.
  • VerifiedA referendum on whether Scotland should be independent relates to two reserved matters: the Union of Scotland and England, and the Parliament of the United Kingdom.
  • VerifiedThis was so even though the referendum would be advisory, because it would have important political consequences.
  • VerifiedThe Court rejected an argument from the SNP, which intervened, based on the right to self-determination in international law.
  • VerifiedThe reserved matters can be changed, for example by an Order in Council, which would allow such a referendum.

Why is it politically significant?

The judgment shows that devolution in the UK is a delegation of power from Westminster rather than a sharing of sovereignty. It also shows the Supreme Court acting as arbiter of the devolution settlement.

Arguments and counterarguments

Which arguments does it support?

Legal sovereignty remains at Westminster despite devolution

Reasoning
If devolved bodies cannot act on reserved matters, final legal authority stays with the UK Parliament.
Evidence
The Court ruled the Scottish Parliament could not legislate for an independence referendum without the reserved matters being changed.
How it supports the argument
The decision on whether Scotland can hold such a referendum rests at UK level.

The Supreme Court acts as an umpire of the constitution

Reasoning
Disputes between governments about powers need an authoritative referee.
Evidence
The Lord Advocate referred the question directly to the Court before the bill was introduced.
How it supports the argument
Both governments treated the Court as the body to settle a major constitutional dispute.

Which counterarguments exist?

A different conclusion

Political sovereignty may lie elsewhere

The ruling settles legal power, not political legitimacy. Supporters of independence argue that sustained electoral support could make refusal politically unsustainable.

Other explanations

Devolution is entrenched in practice

Although legally subordinate, devolved institutions would be politically very hard to abolish, so legal sovereignty may overstate Westminster’s practical power.

Limits of the evidence

The Court interpreted a statute

The judgment applied the Scotland Act. It does not show the Court taking a view on independence itself.
