- A Section 30 order is a mechanism under the Scotland Act 1998 that temporarily transfers a reserved power from Westminster to Holyrood, allowing the Scottish Parliament to legislate on that matter.

Background
Section 30 of the Scotland Act 1998 is the legal instrument by which Westminster can temporarily transfer powers to Holyrood to legislate on matters — including independence referendums — that normally fall outside devolved competence. On the day before the 7 May 2026 elections, John Swinney committed to requesting a Section 30 order 'on the first sitting day after appointment of the new government' and introducing a draft referendum bill within 100 days, regardless of the SNP's final seat total.
The mechanism has been contested since the 2014 independence referendum. Westminster granted a Section 30 order for that vote but rejected Nicola Sturgeon's 2017 and 2019 requests. The UK Supreme Court ruled in November 2022 that Holyrood lacked the power to legislate for a referendum without Westminster consent. Health Secretary Wes Streeting stated publicly he would refuse a Section 30 regardless of the 2026 result.
YouGov's final Holyrood MRP projects the SNP at 62 seats — three short of Swinney's 65-seat named trigger — but the party has framed any majority Coalition with the Scottish Greens as sufficient mandate to proceed.
