Edinburgh Agreement

The Edinburgh Agreement is the accord signed on 15 October 2012 between the UK Government (represented by Prime Minister David Cameron) and the Scottish Government (represented by First Minister Alex Salmond) that established the legal framework for the 2014 Scottish independence referendum. The agreement triggered a Section 30 order under the Scotland Act 1998, temporarily granting the Scottish Parliament the power to legislate for a legally binding referendum — a power otherwise reserved to Westminster.

The key provisions of the Edinburgh Agreement include: both governments committing to respect the referendum result; the referendum being held on a single yes/no question; the franchise being extended to 16 and 17-year-olds for the first time in a Scottish national vote; and the referendum being held by 18 September 2014. The result was 55.3% No, 44.7% Yes.

The Edinburgh Agreement has become the primary legal and political precedent for all subsequent Section 30 debates. The SNP and Scottish Government argue it established that a sufficiently large pro-independence Holyrood majority creates a political obligation on Westminster to grant a new Section 30. The UK Government under both Conservative and Labour administrations has rejected this reading, arguing the 2014 referendum was "once in a generation." The 2023 UK Supreme Court ruling confirmed that Holyrood cannot legislate for a legally binding referendum without a Section 30 order — making the Edinburgh Agreement the only established route to a legally recognised second referendum.
