1.8 Continuity of Scots Law and the Courts
What happens to Scots law and the court system?
The core question is foundational to legal certainty: what happens to Scots law and the court system on independence? The short answer is continuity in full force. All existing legislation, common law, and court structures remain in place unless and until the Scottish Parliament changes them. The Court of Session and the High Court of Justiciary continue as the superior courts. This is one of the strongest continuity advantages Scotland already possesses.
Legal certainty is a basic condition of an orderly transition. Contracts, property titles, criminal convictions, family orders and commercial rights must remain enforceable without interruption. Independence does not create a new legal system from scratch. It removes the remaining limitations on the Scottish Parliament’s power to legislate and ends the appellate jurisdiction of the UK Supreme Court in Scottish cases. The existing body of law simply continues. The existing court structure simply continues. Reform remains possible after independence; it builds on a stable base, not a blank sheet.
The main design choice is explicit continuity of law and courts, with a separate, managed end to UK Supreme Court appeals and transitional arrangements for ongoing cases. The main constraints are operational—the capacity of the courts and the legal profession through the transition—and institutional—the establishment of a new final court of appeal. Neither requires UK agreement for the continuity of Scots law itself. UK cooperation is relevant to the orderly wind-down of Supreme Court jurisdiction and to any shared administrative arrangements; it is not a condition of the law remaining in force. The 18–24 month working timeline, the continuity of the Scottish Parliament and Government, and the interim constitution already defined supply the institutional frame within which legal continuity is secured. Precision about the unbroken force of existing law and the continuity of the courts below the final appellate level is therefore a core operational requirement for every other continuity claim in this framework—from sterling-denominated contracts to property rights, criminal justice and family status.
Current Position and Legal/Institutional Baseline
Scotland has always maintained a separate legal system from the rest of the United Kingdom. Scots law is a mixed system with roots in both civil law and common law traditions. It has its own principles of property, contract, criminal law, family law and succession. The Acts of Union 1707 preserved the distinctiveness of Scots law, and that distinctiveness has been maintained for more than three centuries. The Scottish Parliament already legislates for large areas of Scots law under the competence conferred by the Scotland Act 1998. The Scottish courts already administer it. The Court of Session is the superior civil court; the High Court of Justiciary is the superior criminal court; the Sheriff Courts and Justice of the Peace Courts handle most first-instance business. The judiciary holds office with security of tenure under existing arrangements.
The UK Supreme Court currently exercises appellate jurisdiction in Scottish civil cases and a limited residual role in criminal matters. That jurisdiction follows from the Union and the statutory framework that places final appeals from Scottish courts in a UK-wide court. Independence ends that arrangement. The baseline after a lawful Yes vote and independence settlement is therefore the continuation of a fully functioning, distinct legal system whose legislative competence expands to the full range of a sovereign state and whose final appellate jurisdiction becomes exclusively Scottish. Existing rights, obligations, contracts, property titles, criminal convictions and court orders derive their force from Scots law as it stands. That force does not depend on the UK Parliament's continuing sovereignty over Scotland. The practical baseline is a complete institutional infrastructure—courts, judiciary, legal profession, procedural rules and a substantial body of statute and common law—already in daily operation. Few prospective independent states begin from that position. Scotland does.
Mechanism and Delivery
The mechanism is legal continuity by express provision in the independence settlement and the interim constitution. On Independence Day, every Act of the Scottish Parliament remains in force. Every Act of the UK Parliament that applies to Scotland remains in force as part of Scots law until amended or repealed by the Scottish Parliament. The common law of Scotland continues without interruption. Existing rights, obligations, contracts, property titles, criminal convictions and court orders retain their full legal effect. No legal vacuum exists, and no one needs to re-enact the statute book. Individuals, businesses and public bodies do not need to re-negotiate contracts or re-register rights merely because the state's constitutional status has changed. Legal certainty is preserved by design.
UK statutes that apply to Scotland become, in effect, part of the continuing Scots statute book, subject to the full amending power of the Scottish Parliament. That is a normal pattern when a territory becomes independent while retaining the inherited law: the law continues; the legislature that can change it becomes the new state’s legislature. No UK agreement is required for that continuity. UK agreement may be relevant to interpreting statutes that still refer to UK institutions or to cross-border enforcement; those are matters for transitional provision and, where needed, reciprocal arrangements, not for the validity of the law in Scotland.
The existing Scottish court structure continues. The Court of Session remains the superior civil court. The High Court of Justiciary remains the superior criminal court. The Sheriff Courts and Justice of the Peace Courts continue their current functions. The judiciary remains in post with existing security of tenure. The interim constitution would secure the judiciary's appointments, tenure, and independence and, later, the permanent constitution, consistent with ordinary constitutional standards for judicial independence. The justice system—civil litigation, criminal trials, family proceedings and commercial disputes—would continue operating without structural disruption. Judges, practitioners and court staff work within the same institutional framework they already know.
The UK Supreme Court's appellate jurisdiction in Scottish cases would end on Independence Day. A new final court of appeal for Scotland would be established, as set out in the following section of this framework. Transitional arrangements would cover cases already in progress so that no litigant is left without a forum. Clear rules enacted in advance would determine how pending appeals are treated, how records are transferred or concluded, and any necessary interim measures. Ending that appellate link does not affect the continuity of Scots law itself; it completes the Scottish system's judicial independence. While the existing law continues, the Scottish Parliament gains complete power to amend, repeal or replace any part of it. Areas previously constrained by UK reservations, or by the need to remain compatible with UK-wide frameworks, become fully open to Scottish legislation. Reform can proceed according to Scottish priorities and democratic decisions, but it builds on a stable, continuous legal base rather than a blank sheet.
Continuity Design
Continuity of Scots law and the courts is a design requirement, not a slogan. Existing rights and obligations remain enforceable. Contracts, including those denominated in sterling, retain their force. Property titles remain valid. Criminal convictions and sentences continue to have effect. Family orders, succession rights and personal status matters remain stable. Commercial arrangements face no sudden rupture in the applicable rules. The legal profession and judiciary operate within a familiar system, reducing transition risk for the administration of justice itself.
The interim constitution would give express effect to this continuity. The independence settlement would confirm that existing law continues unless and until the Scottish Parliament changes it. Transitional provisions would manage the wind-down of UK Supreme Court jurisdiction and the treatment of pending cases. Dual-running or reciprocal arrangements for cross-border enforcement, where needed, would protect the practical effect of Scottish judgments and the recognition of rights across the border. The default is continuity of legal relationships. Any break—whether in substantive law, court structure below the final appellate level, or the enforceability of existing orders—must be justified, negotiated and managed. The framework rejects any approach that would require re-enactment of the statute book or structural redesign of the existing courts as a condition of independence. Continuity first protects rights and commercial certainty. Legislative freedom second allows reform without forcing the entire body of law through a single independence-day re-enactment.
Constraints and Trade-offs
Legal constraints
Continuity of Scots law itself does not require UK agreement. The force of existing legislation, common law and court orders in Scotland is a matter of Scottish legal continuity once the independence settlement and interim constitution take effect. The ending of UK Supreme Court jurisdiction is a consequence of independence and of the Scottish constitutional settlement; it does not require the UK’s permission for Scots law to continue. Cooperation is desirable for the orderly transfer or conclusion of pending cases and for practical matters such as records and cross-border enforcement. If cooperation were limited, Scottish legislation and the new final court would still provide a forum. The legal constraint is therefore limited: clear transitional rules must be enacted in advance, and Scottish legislation or reciprocal arrangements must address any residual UK statutory references that assume continuing UK institutions. The validity of the continuing law does not depend on those residual points.
Fiscal constraints
Continuity of the existing courts does not require building a new court system on Independence Day. The fiscal cost is therefore incremental: the cost of establishing and operating a new final court of appeal, plus any transitional administrative costs associated with winding down Supreme Court jurisdiction and managing pending cases. These costs sit inside the ordinary justice budget, supplemented as needed for the new appellate function, and within the medium-term fiscal plan. Capacity constraints are real if caseloads rise or if the new final appellate tier needs time to establish procedures; they are manageable within the transition timeline. The fiscal constraint is modest relative to the costs of building tax capacity, payment systems or diplomatic infrastructure. Honesty about the incremental cost of the new final court is part of credibility; retaining UK Supreme Court appeals indefinitely would avoid that cost at the price of incomplete judicial independence.
Operational constraints
Operational delivery of continuity requires court administration, judicial capacity, procedural rules, and the legal profession to continue functioning through the transition. Caseload management, the induction of the new final court of appeal, and the handling of transitional cases from the UK Supreme Court impose real operational demands. Judicial and court staff capacity is finite. The operational constraint is maintaining ordinary business—civil, criminal, family and commercial—while absorbing the institutional change at the final appellate level and any temporary increase in transitional work. Prioritisation, clear transitional rules enacted in advance, and adequate resourcing of the new appellate function are the design response. Continuity of the courts below the final appellate level does not itself create a new operational burden; the burden arises from the managed change at the apex of the system and from the general pressures of the transition period.
Political constraints
Political pressure for more radical legal redesign, or for symbolic rupture with the existing statute book, is foreseeable. Critics may argue that continuity of UK statutes applying to Scotland is incomplete independence, or that the court system should be substantially remodelled on day one. The political constraint is the need to maintain the integrity of the continuity rule against maximalist demands for rupture. The response is that continuity of existing law, subject to the full amending power of the Scottish Parliament, is standard practice in state succession and in the experience of territories that become independent while retaining a received body of law. UK statutes that apply to Scotland continue as Scots law until the Scottish Parliament changes them; they do not continue as exercises of UK parliamentary authority over Scotland. The distinction is legal and practical: the rules stay; the ultimate legislature changes. That is continuity with sovereignty, not continuity without it. Political credibility depends on defending that distinction rather than conceding to demands for unnecessary legal disruption.
Time constraints
The continuity of substantive law and of the existing courts must be effective on Independence Day and therefore sits inside the 18–24 month working timeline. Preparation of clear transitional rules for pending Supreme Court cases, the legislative provision for continuity in the independence settlement and interim constitution, and the establishment of the new final court of appeal must be completed within that window, or justified for extension. The time constraint is real for the institutional change at the final appellate level; it is modest for the continuity of the law and courts below that level. Competence in designing transitional arrangements and the readiness of the new final court take priority over artificial speed. A delayed but orderly wind-down of Supreme Court jurisdiction is preferable to an abrupt cut that leaves litigants without a clear forum.
Consistency with the Wider Framework
Continuity of Scots law and the courts underpins continuity of contracts, including those denominated in sterling under the sterlingisation model, property rights, criminal justice and family rights. It aligns with continuity of Parliament and Government: the same institutions continue, under continuing law, with expanded competence. It aligns with the interim constitution, which would give express effect to legal and institutional continuity. The end of UK Supreme Court appeals is the main structural change and is handled as a discrete, managed step leading into the establishment of a new final court of appeal. There is no tension with currency, borders, defence or fiscal sections: those are policy and institutional settlements within a continuing legal order, not replacements for it.
Sterling-denominated obligations remain enforceable under continuing Scots law. Property rights that secure lending and investment remain stable. Criminal law and procedure continue, protecting public safety and the rights of accused persons. Family law, succession and personal status matters remain stable for individuals and families. The legal profession and judiciary operate within a familiar system, reducing transition risk for the administration of justice and for the commercial and personal dealings that depend on it. Day-one institutions, the fiscal rules, the nuclear basing agreement and the enhanced Common Travel Area-style movement framework all operate within this continuing legal order. Continuity of law is the platform on which those settlements rest. The framework treats that platform as a strategic advantage and designs the transition to use it in full.
Hardest Critiques and Direct Responses
Feasibility
The hardest practical critique is that “nothing changes” in the law on Independence Day is either unrealistic or insufficiently independent, and that the capacity to establish a new final court of appeal while maintaining ordinary court business is overstated. The response is direct. Continuity of existing law, subject to the full amending power of the new state’s legislature, is standard practice in state succession and in the experience of territories that become independent while retaining a received body of law. The rules stay; the ultimate legislature changes. That is feasible because the institutional infrastructure already exists and operates daily. The new final court of appeal is a focused institutional addition, not a replacement of the Court of Session, the High Court of Justiciary or the sheriff courts. Capacity constraints are real and are addressed by prioritisation, clear transitional rules and adequate resourcing within the transition timeline and the justice budget. Feasibility turns on using the existing system rather than inventing a new one under time pressure.
Cost and fiscal burden
Critics will argue that the incremental costs of a new final court of appeal and of transitional administration impose an unnecessary burden. The response is that continuity of the existing courts avoids the far higher cost of building a new court system. The costs that do arise—establishing and operating the new appellate tier, and transitional administration—are incremental and manageable within the ordinary justice budget and the medium-term fiscal plan. Retaining UK Supreme Court appeals indefinitely would avoid those costs at the price of incomplete judicial independence. Re-enacting the statute book or redesigning the court structure would multiply costs and risks. The framework chooses the lower-cost, lower-risk path of continuity with a focused change at the final appellate level.
Dependence on agreement
Dependence on UK cooperation is limited. Continuity of Scots law itself does not require UK agreement. The ending of Supreme Court jurisdiction is a consequence of independence; cooperation is desirable for the orderly management of pending cases and for practical matters such as records and cross-border enforcement. If cooperation were limited, Scottish legislation and the new final court would still provide a forum. The residual risk would be administrative friction in pending cases, mitigated by clear transitional rules enacted in advance. The response is that this file is among the least dependent on ongoing UK cooperation of any in the prospectus. Substantive legal continuity is a Scottish constitutional act; cooperation improves the management of the appellate wind-down but is not required for validity.
Transition risk
Transition risk arises primarily from the managed end of UK Supreme Court jurisdiction and the establishment of the new final court of appeal, not from the continuity of substantive law or of the courts below the final appellate level. Pending cases require clear rules so that no litigant is left without a forum. The new appellate tier requires time to establish procedures and capacity. Mitigation includes early enactment of transitional provisions, prioritising readiness for the new court, and maintaining continuity in the existing superior and first-instance courts so ordinary business continues. The framework does not claim that transition risk is zero; it claims that continuity of the bulk of the system and focused management of the single structural change at the apex minimise the risk. Re-enacting the statute book or structurally redesigning the existing courts would multiply transition risk without necessity.
Alternatives (status quo and previous proposals)
Re-enacting the entire statute book on independence would create an enormous legislative load, increase the risk of gaps and errors, and undermine legal certainty. That alternative is rejected in favour of continuity with full power to amend thereafter. Immediate structural redesign of the court system would add institutional risk during the transition without necessity. That alternative is rejected in favour of continuity of existing courts, with change limited to the final appellate level. Retaining UK Supreme Court appeals indefinitely would leave final interpretation of Scots law in a court of another state. That is incompatible with full judicial independence of an independent Scotland and is rejected in favour of a Scottish final court of appeal, with transitional arrangements for pending cases. The status quo of UK Supreme Court jurisdiction ends with independence; the framework replaces it with a managed Scottish alternative while preserving the continuity of the law and the courts that already function daily.
Political and public credibility
The claim most likely to be called unrealistic is that continuity of UK statutes applying to Scotland is incomplete independence, or that “nothing changes” fails to mark the constitutional break. The precise answer is that the rules stay; the ultimate legislature changes. UK statutes that apply to Scotland continue as Scots law until the Scottish Parliament changes them; they do not continue as exercises of UK parliamentary authority over Scotland. That distinction is legal and practical. Credibility with households, businesses, the legal profession and international counterparties depends on the enforceability of existing rights and obligations without interruption. A strategy that forced re-enactment or structural rupture for symbolic reasons would forfeit that credibility when legal certainty matters most. The framework defends continuity with sovereignty as the position that protects rights and reduces risk while completing legislative and judicial independence.
Position Summarised
Scots law continues in full force. Existing legislation, common law and court structures remain in place and fully effective. The Court of Session and High Court of Justiciary continue as the superior courts. The Scottish Parliament gains complete power to change the law after independence, but it does so from a position of unbroken legal continuity. The appellate jurisdiction of the UK Supreme Court ends on Independence Day; a new final court of appeal is established, with transitional arrangements for ongoing cases. Legal certainty for citizens, businesses and institutions is preserved from the first day of independence. This is one of Scotland's most significant practical advantages. Continuity of law is a design rule, not a slogan: existing rights and obligations remain enforceable; reform remains possible through ordinary democratic process under the new constitutional order. Continuity of the courts below the final appellate level, security of judicial tenure, and the familiar institutional framework of the justice system reduce transition risk and protect the daily administration of justice. The managed end of Supreme Court jurisdiction completes judicial independence without disturbing the substance of the law or the operation of the existing courts.
Conclusion
Scots law and the Scottish courts continue without interruption. Independence expands legislative competence and ends UK Supreme Court appeals in Scottish cases; it does not wipe the statute book or replace the Court of Session, the High Court of Justiciary or the sheriff courts. Existing rights, contracts, convictions and orders retain their effect. The Scottish Parliament can amend or repeal any part of the continuing law after independence; it does so from a stable base. That continuity is one of the clearest practical advantages available to Scotland. It protects legal certainty for households and businesses, reduces transition risk for the justice system, and allows reform to proceed deliberately rather than through emergency re-enactment. The managed end of Supreme Court jurisdiction completes judicial independence without disturbing the substance of the law or the operation of the courts below the final appellate level. Continuity of law and courts is therefore both a democratic strength and an operational necessity—and this framework treats it as such. Every subsequent section of this series—on contracts under sterlingisation, property rights, criminal justice, family status, the interim constitution and the new final court of appeal—presupposes a continuing body of Scots law and a functioning court system. This section ensures that presupposition is delivered as a deliberate design choice rather than left as an unexamined assumption.

This analysis forms part of People’s Future Scotland: The Independence Debate, a series examining the practical, legal and institutional questions that would arise in any move to independence. Each section is designed to withstand scrutiny by setting out mechanisms, constraints and continuity requirements with equal clarity. The series proceeds from the premise that a decision of this magnitude requires a process and a prospectus that both supporters and opponents can recognise as serious.
