Why Scotland Cannot Currently Call Its Own Independence Referendum
Scotland has the institutions, legislation and administrative ability to conduct another independence referendum—but Holyrood cannot presently authorize the vote. This DCN explainer examines the 2014 agreement, the Supreme Court’s 2022 ruling, the legal routes that remain and why no democratic threshold currently requires Westminster to transfer the necessary power.
Scotland held a lawful referendum in 2014—but under the present constitutional settlement, Holyrood cannot authorize another vote without Westminster’s cooperation.
Scotland has a parliament elected by the people of Scotland. It has its own government, makes laws and controls significant areas of public policy.
But it cannot currently authorize a lawful referendum on whether Scotland should become an independent country.
That apparent contradiction lies at the center of the modern independence debate.
The obstacle is not primarily administrative. Scotland has held referendums before, and the Scottish Parliament has legislation governing how referendums can be conducted.
The obstacle is constitutional authority.
Under the Scotland Act 1998, the Union between Scotland and England and the authority of the United Kingdom Parliament are reserved matters. Because those subjects remain under Westminster’s control, Holyrood cannot legislate unilaterally for a referendum intended to ask whether Scotland should leave the United Kingdom.
The central question is therefore not whether Scotland is capable of organizing a referendum.
It is who has the legal power to authorize one.
How the 2014 referendum became possible
The Scottish independence referendum held on September 18, 2014, was legally authorized through an agreement between the Scottish and UK Governments.
Following the 2011 Scottish Parliament election, the SNP government argued that it had received a mandate to hold an independence referendum. The UK Government agreed to negotiate a temporary transfer of power.
The resulting Edinburgh Agreement was signed in October 2012. Both governments committed themselves to a referendum that would have a clear legal basis, be legislated for by the Scottish Parliament and produce a result respected by both sides.
Westminster then approved the Scotland Act 1998 (Modification of Schedule 5) Order 2013.
This was known as a Section 30 order, named after the provision of the Scotland Act allowing adjustments to be made to the boundaries of devolved competence.
The order created a temporary exception to the reservation of constitutional matters. It allowed the Scottish Parliament to legislate for one independence referendum, subject to specified conditions and timing.
Holyrood then passed the legislation required to conduct the vote.
The result was 55.3 percent for remaining in the United Kingdom and 44.7 percent for independence.
The important legal point is that the Scottish Parliament did not possess a permanent power to call independence referendums. It received limited authority for that particular vote through an agreement requiring Westminster’s participation.
Once the 2014 process concluded, the temporary authorization expired.
Why the question is reserved
The Scottish Parliament operates under powers established by the Scotland Act 1998.
Under Schedule 5 of the Act, reserved constitutional matters include the Union of the Kingdoms of Scotland and England and the Parliament of the United Kingdom.
The Scottish Parliament can legislate in devolved areas, but a provision is outside its competence if it relates to a reserved matter.
For many years, independence supporters argued that Holyrood might nevertheless be able to organize a referendum that was legally advisory rather than self-executing.
Under that argument, the referendum itself would not dissolve the Union. A Yes result would express the electorate’s view and create a political mandate for negotiations, but further legislation would still be needed before Scotland became independent.
That legal theory was eventually tested before the UK Supreme Court.
What the Supreme Court decided
In 2022, Scotland’s Lord Advocate referred a proposed Scottish Independence Referendum Bill to the UK Supreme Court.
The proposed bill would have asked:
“Should Scotland be an independent country?”
The Scottish Government maintained that the referendum would be advisory. It would not, by its own force, end the Union or alter the powers of either parliament.
On November 23, 2022, the Supreme Court ruled unanimously that the proposed legislation was outside the Scottish Parliament’s competence.
The Court concluded that a referendum on independence would relate to the reserved matters of the Union and the UK Parliament. Even without automatic legal consequences, the vote would be designed to produce significant political effects.
Its advisory status did not remove it from the constitutional reservation.
The Court did not decide whether Scotland should be independent. It did not rule that Scotland could never become independent, and it did not determine whether the Scottish Government possessed a political mandate for a referendum.
It answered a specific question of domestic constitutional law: could the Scottish Parliament enact the proposed referendum bill without Westminster first altering its legal powers?
The answer was no.
What the Court said about self-determination
The Scottish National Party also made submissions concerning the international legal principle of self-determination.
The Supreme Court considered international authorities addressing situations such as colonial rule, foreign occupation and circumstances in which a people is denied meaningful access to government.
The Court concluded that those principles did not change the limits imposed on the Scottish Parliament by the Scotland Act.
This did not amount to a judicial declaration that Scotland is not a nation or that its people have no democratic voice. It meant that the international-law arguments presented did not give Holyrood a unilateral power absent from the UK’s domestic constitutional settlement.
The political and moral debate over Scotland’s right to choose continued.
The proposed legal route through unilateral Holyrood legislation did not.
What has changed since the ruling?
The Scotland Act has not been amended to give the Scottish Parliament permanent authority over independence referendums.
The Scottish Government published a new draft Independence Referendum Bill on August 28, 2026. It again proposes the question used in 2014.
But the government has said it will introduce the legislation only after the necessary powers have been secured.
That condition is crucial.
The draft shows that Scotland is administratively and legislatively prepared to conduct a referendum. It does not overcome the legal restriction identified by the Supreme Court.
The bill is therefore ready, but it cannot presently be activated.
What lawful routes remain available?
Several lawful routes could make another referendum possible. Each requires action involving Westminster.
1. Another Section 30 order
The Scottish and UK Governments could negotiate another temporary modification of the Scotland Act, following the broad model used before the 2014 referendum.
A new order could specify:
- the period during which Holyrood may legislate;
- whether authority applies to one referendum;
- any requirements concerning timing;
- the legal framework governing the vote; and
- other agreed conditions.
This is the route most clearly supported by precedent.
However, a Section 30 order requires political cooperation. The Scottish Government cannot compel the UK Government to negotiate one under existing law.
2. Legislation passed at Westminster
The UK Parliament could pass legislation directly authorizing a Scottish referendum.
It could also amend the Scotland Act to transfer referendum authority permanently or establish circumstances in which a vote must be held.
Again, this would require sufficient political support at Westminster.
3. A new statutory trigger mechanism
Parliament could create objective conditions for another Scottish referendum.
For example, legislation could identify a sustained level of public support, repeated electoral mandates or another measurable threshold that would activate a duty to authorize a vote.
Scotland does not currently have such a mechanism.
That makes its position different from Northern Ireland, where the Northern Ireland Act 1998 establishes a legal process for a border poll when the secretary of state believes a majority would be likely to support Irish unification.
The Scottish first minister has now asked the UK Government to discuss creating a comparable—though necessarily Scotland-specific—legal route.
The UK Government has not agreed.
Does winning an election create the legal power?
An election can create a political mandate. It does not automatically expand the Scottish Parliament’s legal competence.
If voters elect a majority of MSPs who support a referendum, those representatives can vote for motions, publish legislation and press Westminster to transfer the necessary powers.
But the election result does not itself amend Schedule 5 of the Scotland Act.
The same distinction applies to opinion polls. Sustained majority support for independence or another referendum could create significant democratic and political pressure, but it does not automatically trigger a legal process under the present system.
This is one of the most consequential features of Scotland’s constitutional position:
No specified number of pro-independence MSPs, election victories or favorable opinion polls currently requires the UK Government to authorize a referendum.
Political mandates can be argued.
The legal power remains reserved.
The September 2026 dispute
The absence of an agreed threshold became especially visible during Prime Minister’s Questions on September 9, 2026.
SNP MP Chris Law asked Prime Minister Andy Burnham whether Scotland should have an equal right to choose its future and whether the conditions for another referendum should be written into law.
Burnham compared the political situation with the process governing Northern Ireland. He told the House that a referendum would not occur while majority public support was absent, appearing to suggest that a change in public opinion could require the question to be reconsidered. The full exchange appears in the official Hansard record.
First Minister John Swinney responded by inviting Burnham to negotiate an agreed legal mechanism. His September 10 letter asked the prime minister to define how majority support could translate into a lawful referendum.
Burnham subsequently said he had not changed government policy and rejected the request, maintaining that independence and another referendum remain “off limits.” His response was reported by The Times.
The exchange revealed the unresolved problem with unusual clarity.
The prime minister publicly connected the possibility of a vote to majority support. Scotland’s first minister asked him to convert that principle into law. The UK Government declined to do so.
As a result, no legal threshold exists.
Political consent and legal consent are not the same
Much of the independence debate turns on the difference between two kinds of authorization.
Political consent concerns whether Scotland’s electorate supports another referendum or independence itself.
Legal consent concerns whether Westminster authorizes Holyrood to hold the vote.
Under the current settlement, political support in Scotland does not automatically produce legal authority in Scotland.
Supporters of the Union may argue that the 2014 referendum settled the matter and that governments should focus on public services and the economy.
Independence supporters may answer that no democratic decision binds future generations permanently and that a voluntary union must contain a lawful means through which its members can reconsider their consent.
Those are competing political positions.
The established legal fact is that Westminster presently controls access to the recognized referendum process.
Is the Union voluntary?
UK governments commonly describe the United Kingdom as a voluntary union.
But Scotland has no standing legal right to initiate a referendum when its own elected institutions believe the question should be asked.
That produces a difficult constitutional question:
What makes a union voluntary if one party to it cannot lawfully reconsider membership without the permission of the government committed to maintaining it?
Union supporters may respond that Scotland participates fully in UK democracy, elects members of the UK Parliament and exercised its choice in 2014.
Independence supporters may respond that representation within UK institutions is not equivalent to Scotland possessing the continuing right to determine its national status.
That question was not resolved by the Supreme Court. It is a matter of constitutional principle, democratic legitimacy and political judgment.
Why this matters to Christians
Christians can disagree about independence. Supporting or opposing the Union should not be treated as a measure of faith.
But the integrity of the democratic process should matter to Christians on both sides.
The referendum dispute raises questions about truth, consent, justice, peaceful political change and the responsible exercise of authority.
If Scotland is entitled to choose, there should be a clear and lawful way to express that choice.
If the UK Government believes another referendum should not occur, it should explain what democratic conditions—if any—would justify one.
A system with no defined route risks replacing constitutional principle with political discretion. The answer can change depending upon who controls Westminster, even when Scotland’s electorate continues to return representatives seeking a vote.
Christians concerned with peace and justice should value lawful, transparent and nonviolent mechanisms for resolving national disagreements. Uncertainty about the rules can deepen frustration and mistrust.
A democratic constitutional system should make clear not only how power is retained, but how consent can be reconsidered.
The Scotland’s Les Misérables position
Scotland’s Les Misérables is a survivor-founded cause for justice and Scottish independence.
From the cause’s perspective, Scotland’s inability to authorize its own referendum illustrates the difference between having devolved institutions and possessing national self-determination.
Scotland can debate independence. Its people can organize, campaign and elect representatives who support it. Its government can prepare legislation.
But Scotland cannot presently initiate the decisive democratic process through its own institutions.
The cause supports a lawful and peaceful referendum. It does not argue that constitutional change should occur without democratic consent.
Its position is that consent must not be controlled indefinitely by the government seeking to preserve the existing arrangement.
A union should be able to defend itself through persuasion. It should not depend upon withholding the means through which a member nation can express its choice.
The answer
Why can Scotland not currently call its own independence referendum?
Because the constitutional status of the Union is reserved to Westminster. The UK Supreme Court has ruled that Holyrood cannot legislate unilaterally for the proposed vote, even if the result would initially be advisory.
Another lawful referendum remains possible.
But under the existing settlement, it would require a Section 30 order, legislation passed by the UK Parliament or another agreed change to Scotland’s constitutional powers.
Scotland has the institutions necessary to conduct the vote.
It has political parties and civic organizations prepared to contest it.
It has a government that has published draft legislation.
What Scotland does not possess is the final legal authority to decide when its people may be asked the question.
That authority remains at Westminster—and no law currently specifies when Westminster must surrender it.
