What Is the Court of Session and When Does a Claim Go There?
Scotland's legal system is built on a hierarchical structure of courts, each with its own jurisdiction, its own procedures, and its own place in the architecture of Scottish justice. At the apex of that structure, for civil matters, sits the Court of Session. It is Scotland's supreme civil court — the highest civil court within the Scottish court system itself, before any question of appeal to the UK Supreme Court arises — and it occupies a position of constitutional, historical, and practical significance that distinguishes it from every other civil court in Scotland.
For most people involved in personal injury claims in Scotland, the Court of Session is a name they will encounter but a court they will never need to enter. The creation of the All-Scotland Sheriff Personal Injury Court under the Courts Reform (Scotland) Act 2014, and the extension of the sheriff court's privative jurisdiction to one hundred thousand pounds, redirected the vast majority of personal injury litigation in Scotland to the sheriff court tier. The Court of Session is no longer the default forum for personal injury cases of any significant value — it is a court reserved for the most serious, most complex, or most legally significant cases that the Scottish personal injury system produces.
Understanding what the Court of Session is, how it is structured, what its historical significance is, what its relationship with other courts looks like, and when a personal injury case goes there rather than to the sheriff court is important context for anyone with a serious injury claim in Scotland or anyone seeking to understand how the Scottish civil justice system operates at its highest level.
History and Constitutional Significance
The Court of Session is one of the oldest judicial institutions in Scotland. It was established by an Act of the Scottish Parliament in 1532, during the reign of James V, and has sat continuously as Scotland's supreme civil court ever since — surviving the Acts of Union in 1707, the creation of the United Kingdom, and the devolution settlement of 1998 with its status and jurisdiction intact.
The court's establishment in 1532 was itself a significant moment in Scottish legal history. Before the Court of Session existed, civil justice in Scotland was administered by a variety of institutions including the Lords of Council, whose jurisdiction over civil matters was formalised and consolidated into the new court. The creation of a permanent, professionally staffed supreme civil court marked the beginning of the systematic development of Scots private law — the body of law governing obligations, property, and civil rights that distinguishes Scotland's legal tradition from that of England.
The Court of Session sits in Parliament House in Edinburgh — a building that also housed the old Scottish Parliament before the Acts of Union and that remains one of the most historically significant legal buildings in Europe. The court has sat in Parliament House since 1639, and the building itself, with its magnificent Parliament Hall, is a physical expression of the continuity and institutional weight of Scotland's legal tradition.
The Acts of Union in 1707 preserved the Court of Session as Scotland's supreme civil court. Unlike many other Scottish institutions that were affected or absorbed by the union, the Court of Session emerged from 1707 with its jurisdiction and its distinctive character intact — a reflection of the explicit guarantee in the Treaty of Union that Scots private law and the Scottish court system would be maintained.
The court's constitutional significance is not merely historical. In the modern devolution settlement, the Court of Session plays an important role in the oversight of the acts and decisions of Scottish public bodies, including the Scottish Government. Judicial review of Scottish executive action — challenges to the legality of decisions made by Scottish Ministers, Scottish Government agencies, and other public authorities — is conducted in the Court of Session's Outer House. This supervisory jurisdiction makes the Court of Session not just Scotland's supreme civil court for private law disputes but an important constitutional court for the devolved settlement.
The Structure of the Court
The Court of Session is divided into two distinct divisions — the Outer House and the Inner House — each of which performs different functions and operates under different procedures.
The Outer House is the court of first instance — the division in which cases are heard for the first time. It is staffed by senators of the College of Justice, who are the judges of the Court of Session, sitting alone. In the Outer House, a single judge — referred to as the Lord Ordinary — hears evidence, determines facts, and applies the law to produce a decision. The Outer House is where new Court of Session actions are raised, where proofs are conducted, and where first instance decisions are made.
The judges of the Court of Session hold the title of Senator of the College of Justice and are addressed as Lord or Lady followed by their judicial title. They are appointed by the Crown on the recommendation of the Judicial Appointments Board for Scotland and must have been advocates or solicitor-advocates of at least five years' standing. The Court of Session judiciary brings specialist expertise to the most complex civil litigation in Scotland, and its judges include specialists in commercial law, public law, family law, and personal injury whose depth of experience in their respective areas is unmatched within the Scottish court system.
The Inner House is the appellate division of the Court of Session — the division that hears appeals from Outer House decisions, from the Sheriff Appeal Court, and from certain other tribunals and courts. The Inner House sits in two divisions — the First Division and the Second Division — each presided over by a senior judge. The First Division is presided over by the Lord President, who is the most senior judge in Scotland's civil court system, and the Second Division by the Lord Justice Clerk, the second most senior judge. Each division typically sits with three judges, and in cases of particular importance a larger bench — an Extra Division — may be constituted.
The Inner House therefore serves as both the appellate court for decisions made in the Outer House and the final Scottish court of appeal for decisions made in the Sheriff Appeal Court. Its decisions constitute binding precedent for all lower courts in Scotland, and its jurisprudence shapes the development of Scots private law across all areas of civil litigation including personal injury.
Appeals from the Inner House of the Court of Session lie to the UK Supreme Court, which sits in London and hears appeals from all three UK jurisdictions. The UK Supreme Court's decisions on matters of Scots law — particularly on areas that are UK-wide in their reach, such as employer's liability, the interpretation of UK-wide statutes, and the application of the European Convention on Human Rights — bind the Scottish courts. In areas of purely Scottish private law, the Inner House remains the primary source of binding authority, and the Supreme Court's willingness to intervene in matters of pure Scots law has historically been limited.
Jurisdiction in Personal Injury Cases
Before the Courts Reform (Scotland) Act 2014, the Court of Session had concurrent jurisdiction with the sheriff court over personal injury cases of any value. A claimant could choose to raise their action in either court, and many chose the Court of Session even for cases of relatively modest value — partly for historical and reputational reasons, partly because the expenses regime in the Court of Session was more generous to successful claimants, and partly because the Court of Session's more developed procedural infrastructure offered advantages in complex cases.
The 2014 Act changed this fundamentally. By raising the sheriff court's privative jurisdiction threshold to one hundred thousand pounds, it removed the choice of forum for claims worth up to that amount. Cases worth one hundred thousand pounds or less must now be raised in the sheriff court — they cannot be raised in the Court of Session. Only claims above the one hundred thousand pound threshold can be raised in the Court of Session as of right.
This jurisdictional threshold is not the only route by which a personal injury case reaches the Court of Session. There is a procedure for transferring cases from the All-Scotland Sheriff Personal Injury Court to the Court of Session where the legal or factual complexity of the case makes it more appropriate for the higher court. The decision to transfer is made by the sheriff on the application of either party or on the court's own motion, and it requires a positive finding that the complexity of the case justifies the transfer rather than being a routine procedural option. Transfers are therefore relatively uncommon — they arise in cases where genuinely exceptional legal issues or factual complexity makes the Court of Session a more appropriate forum despite the sheriff court's jurisdiction.
When Does a Personal Injury Case Go to the Court of Session?
In the post-2014 landscape, a personal injury case goes to the Court of Session in four main categories of situation.
The first and most common is where the claim is valued at more than one hundred thousand pounds and the claimant's solicitor decides to raise the action in the Court of Session rather than in the sheriff court. Above the one hundred thousand pound threshold, the claimant has a choice of forum, and the decision of which court to use involves a number of considerations that are discussed below.
The second is where a case is transferred from the All-Scotland Sheriff Personal Injury Court to the Court of Session because of exceptional legal complexity or other features that make the Court of Session a more appropriate forum. These are relatively rare cases that present novel legal questions, complex technical issues, or circumstances that genuinely benefit from the specialist expertise and the higher appellate authority of the Court of Session.
The third is where the case involves a judicial review element — a challenge to the lawfulness of a decision made by a public body in connection with the personal injury matter. A challenge to NHS Scotland's handling of a clinical negligence complaint, or a challenge to a decision made by the Criminal Injuries Compensation Authority, may involve judicial review proceedings that must be brought in the Outer House of the Court of Session regardless of the financial value of the underlying claim.
The fourth is on appeal — where a case that was decided in the All-Scotland Sheriff Personal Injury Court or the Sheriff Appeal Court is appealed to the Inner House of the Court of Session on a point of law. The appellate jurisdiction of the Inner House means that Court of Session judges will hear and decide the most important legal questions arising from personal injury litigation even where the original proceedings took place in the sheriff court.
The Decision to Use the Court of Session: Strategic Considerations
Where a personal injury claim is above the one hundred thousand pound threshold and the claimant's solicitor has a genuine choice of forum, the decision of whether to raise the action in the Court of Session or in the All-Scotland Sheriff Personal Injury Court involves a careful analysis of a number of factors.
Expenses are a significant consideration. The expenses regime in the Court of Session — the rules governing how legal costs are calculated and awarded — has historically been more generous to successful claimants than the sheriff court expenses regime. In a high-value case where the claimant succeeds, Court of Session expenses on a party-and-party basis may recover a higher proportion of the claimant's actual legal costs than the equivalent sheriff court award. For cases at the higher end of the value range, this difference in the expenses recovery can be financially significant.
The complexity of the case is another consideration. The Court of Session has specialist judges with extensive experience of the most complex personal injury litigation. In a case involving novel legal issues, complex medical evidence from multiple expert disciplines, or difficult questions of causation — a serious traumatic brain injury case, a complex industrial disease case, or a multi-defender mesothelioma claim — the experience and authority of the Court of Session judiciary may be advantageous.
The procedural differences between the two courts also matter. Court of Session procedure in personal injury cases — the Rules of the Court of Session and the Personal Injury Procedure applicable in the Outer House — differs in detail from the procedure in the All-Scotland Sheriff Personal Injury Court. Experienced personal injury solicitors and advocates will be familiar with both sets of rules, but the nuances of Court of Session procedure in high-value cases require specialist knowledge and experience.
The availability of senior counsel — advocates of Queen's Counsel or King's Counsel rank — is a further consideration. In the Court of Session, it is conventional and often expected that parties in significant cases will be represented by senior counsel. In the sheriff court, solicitor-advocates and junior counsel frequently conduct the full range of personal injury litigation without senior counsel. The instruction of senior counsel adds to the cost of the litigation but brings additional experience and advocacy skills to the most complex and high-value cases.
Procedure in the Court of Session: Personal Injury Actions
Personal injury actions in the Court of Session Outer House are governed by Chapter 43 of the Rules of the Court of Session — a dedicated set of procedural rules specifically designed for personal injury litigation that was developed to provide a streamlined and efficient procedure for this category of case.
Chapter 43 procedure begins with the lodging of a summons — the formal document that initiates the court action — which is then signeted by the court and served on the defender. The summons in a Court of Session personal injury action must contain the essential averments of fact and law on which the pursuer's case is founded, identifying the accident, the defender's negligence, the injuries sustained, and the basis of the claim.
Following service of the summons, the defender lodges defences setting out their response to the pursuer's averments. The pleadings process in a Court of Session personal injury action differs from the equivalent sheriff court process in its level of detail and formality — Court of Session pleadings are typically more elaborately developed and more technically precise than sheriff court pleadings, reflecting the higher-value and often more complex nature of the cases that reach the Court of Session.
The procedural timetable in a Chapter 43 personal injury action is managed by the Keeper of the Rolls and by the court itself. A timetable is issued specifying the dates by which the parties must complete various procedural steps — lodging of expert reports, adjustment of pleadings, fixing of a diet of proof. Active judicial management is a feature of Court of Session personal injury procedure, with the Lord Ordinary taking an interest in the progress of the case through procedural hearings and ensuring that the parties are moving toward resolution efficiently.
The proof in a Court of Session personal injury action is conducted before a single Lord Ordinary sitting without a jury — juries are available in the Court of Session for certain categories of case but are not used in personal injury litigation. The Lord Ordinary hears evidence from both sides, considers the submissions of counsel, and delivers a judgment on both liability and quantum. Court of Session judgments in personal injury cases are typically written and may be very substantial documents in complex cases — setting out the Lord Ordinary's findings in fact, their analysis of the medical evidence, their assessment of the witnesses, and their application of the Judicial College Guidelines and the Ogden Tables to the findings.
The Inner House: Appeals in Personal Injury Cases
The Inner House of the Court of Session is the forum in which the most important legal questions arising from personal injury litigation in Scotland are decided. An appeal from a decision of the Lord Ordinary in the Outer House lies to the Inner House, and an appeal from the Sheriff Appeal Court on a point of law of sufficient importance may also reach the Inner House.
Inner House appeals in personal injury cases address a wide range of legal issues — the interpretation of the Hunter v Hanley test in clinical negligence cases, the assessment of damages under the Ogden Tables, the application of the Prescription and Limitation (Scotland) Act 1973, the proper approach to contributory negligence, and the legal principles governing specific heads of loss. The Inner House's decisions on these questions bind all lower courts in Scotland and shape the law that applies to every personal injury claim in the Scottish system.
The procedure for an Inner House appeal involves the lodging of a reclaiming motion — the Scottish term for an appeal from the Outer House — or a stated case or stated note of appeal in cases coming from the Sheriff Appeal Court. The appeal is heard by a bench of three Inner House judges, or in cases of particular importance by an Extra Division of five judges. Written submissions are exchanged and oral argument is heard, typically without the leading of fresh evidence — the Inner House decides the legal questions on the basis of the findings made at first instance and the legal submissions made on appeal.
The Relationship Between the Court of Session and the UK Supreme Court
Appeals from the Inner House of the Court of Session lie to the UK Supreme Court in London. The Supreme Court hears appeals from all three UK legal systems — Scotland, England and Wales, and Northern Ireland — and its decisions on matters of Scots law are binding on all Scottish courts.
In personal injury cases, the UK Supreme Court has decided a number of landmark cases involving Scottish appeals — cases on the law of negligence, on the assessment of damages, on the rules of causation in industrial disease cases, and on the interpretation of legislation applying across the UK. The Fairchild decision on mesothelioma causation, the Rothwell decision on pleural plaques, and the Ogden Tables cases on the discount rate have all involved appeals from Scotland as well as from England, and the Supreme Court's decisions in those cases have shaped the law applicable across Great Britain.
Where a point of Scots private law is not shared with the law of England and Wales — where the question is one that arises specifically from Scotland's distinct legal tradition rather than from UK-wide statute or common principle — the Supreme Court generally accords significant deference to the Inner House's interpretation of Scots law, and the frequency with which purely Scottish private law questions are taken to the Supreme Court is lower than for questions of UK-wide legal principle.
The Court of Session in the Modern Personal Injury Landscape
The Courts Reform (Scotland) Act 2014 fundamentally changed the Court of Session's role in personal injury litigation. The court that had for decades handled the bulk of contested personal injury cases of any significant value now handles a much smaller volume of personal injury work — the most serious, most complex, and most legally significant cases at the top of the value range and the appellate jurisdiction that shapes the law for all courts below.
This change has not diminished the Court of Session's importance to the personal injury system as a whole. Its role in developing the law through Inner House appeals remains as significant as ever. Its jurisdiction over the most serious personal injury cases — catastrophic brain injuries, fatal accidents, complex industrial disease claims, the most serious clinical negligence cases — ensures that the highest-value human consequences of negligence are handled with the depth of expertise and the quality of judicial resource they deserve. And its supervisory jurisdiction over public bodies, including NHS Scotland, means that it remains an important forum for the most significant public interest dimensions of personal injury and clinical negligence litigation.
The Bottom Line
The Court of Session is Scotland's supreme civil court — a judicial institution of five centuries' standing, of profound constitutional significance, and of continuing practical importance to the personal injury system even in the post-2014 landscape where the sheriff court handles the majority of contested personal injury litigation. It is the court that decides the most serious cases, shapes the law through Inner House appeals, and provides the final word on the legal questions that determine the rights of injured people across Scotland.
For claimants with the most serious injuries, for cases involving novel legal questions, and for appeals that will shape the law applicable to every personal injury claimant in Scotland, the Court of Session is the court that matters most. Understanding what it is, how it is structured, and when a claim goes there is essential context for understanding the full architecture of the Scottish personal injury system.
