Definition
The Court of Justiciary is the supreme criminal court of Scotland. It exercises general criminal jurisdiction over all offenses committed anywhere in Scotland, both as a court of first instance for serious crimes and as an appellate court reviewing decisions of inferior criminal courts. It also holds limited appellate jurisdiction in civil matters involving small amounts.
The court is composed of judges drawn from the Court of Session — historically described as lords of session — presided over by the Lord Justice General or, in that officer's absence, the Lord Justice Clerk. To extend its reach across Scotland, the kingdom is divided into circuits, with sessions held periodically in each circuit. A quorum of two justices suffices to hold a term.
As the supreme criminal court, the Court of Justiciary's judgments on criminal matters are final within Scotland. An appeal lies to the House of Lords (now the Supreme Court of the United Kingdom) in civil matters, but historically the finality of the court's criminal jurisdiction was a defining and jealously guarded feature of Scottish law.

Common Confusion
Researchers unfamiliar with Scots law sometimes conflate the Court of Justiciary with the Court of Session. The distinction is fundamental: the Court of Session is Scotland's supreme civil court; the Court of Justiciary is its supreme criminal court. The two share judicial personnel — the same lords of session serve in both capacities — but they are constitutionally and functionally distinct institutions. Historical sources occasionally blur this line when discussing the limited civil jurisdiction of the Justiciary court, which can mislead a researcher into treating the two as interchangeable.

Recognized Forms
/SUBTYPES
High Court of Justiciary: The court sitting in Edinburgh exercising original jurisdiction over the most serious crimes, including murder, rape, and treason. Serious indictable offenses must be tried here.
Circuit Courts of Justiciary: The court sitting on circuit across Scotland's three traditional circuits. These sittings extend the court's reach geographically and handle criminal business arising outside Edinburgh.

Why It Matters in Research
Researchers working with Scottish criminal law sources must understand that the Court of Justiciary is not an intermediate court — it is the apex criminal tribunal, and its criminal rulings are not subject to review by any Scottish court above it. This means that when historical sources refer to an appeal in a Scottish criminal matter being unavailable, they are describing a structural feature of Scots law, not a procedural gap.
The composition of the court has shifted over time. Bouvier's description of "five other members of the court of sessions" alongside the Lord Justice General and Lord Justice Clerk reflects an earlier configuration. Black's 2nd edition describes "five lords of session with the lord president or justice-clerk as president," a slightly different formulation. Burrill is more spare, calling it simply "the supreme criminal tribunal of Scotland." A researcher using these sources in tandem should note that the precise headcount of judges varied across periods and should not treat any one source's composition description as definitive for all eras.
The court's limited civil appellate jurisdiction — over causes involving small amounts — appears in Bouvier and both Black's editions but is absent from Burrill. This civil dimension is a minor but real aspect of the court's historical jurisdiction and should not be overlooked when tracing the boundary between Scottish civil and criminal appellate procedure in older materials.
The House of Lords connection is important for researchers working on British constitutional history or inter-jurisdictional appeals. The civil appellate route to the House of Lords existed alongside the criminal finality rule, creating an asymmetry that confused English observers and occasionally generates confusion in secondary sources.
No direct analog exists in English or American law. Researchers trained in common law jurisdictions should resist mapping the Court of Justiciary onto the English Court of King's Bench or any American state supreme court. The shared-personnel arrangement with the Court of Session is particularly distinctive and has no ready equivalent in American judicial organization.

Historical Dictionary Support
The six source dictionaries converge on the court's essential character — supreme criminal jurisdiction over all of Scotland, both original and appellate — but differ in their detail and emphasis.
Burrill offers the simplest formulation: "the supreme criminal tribunal of Scotland," with a citation to Alison's Criminal Practice. This is reliable as a baseline but too spare to resolve research questions about composition or civil jurisdiction.
Black's 1st and 2nd editions are nearly identical in their treatment, both noting the court's power to try causes and review inferior court decisions, and both noting the civil appellate jurisdiction over small amounts. The 2nd edition is marginally more precise in describing composition.
Bouvier is the most detailed, specifying the circuit structure and the minimum session length (not less than three days each), and noting that any two justices may hold a term. Bouvier also identifies the civil jurisdiction explicitly. Researchers needing procedural granularity will find Bouvier the most useful starting point among the historical dictionaries.
Rapalje & Lawrence tracks Black's closely, adding nothing substantially new but providing a useful confirmation of the dual original-and-appellate character of the court's criminal jurisdiction.
None of the historical dictionaries address the post-devolution context or the restructuring of Scottish courts following the Constitutional Reform Act 2005, which transferred the House of Lords' appellate function to the newly created Supreme Court of the United Kingdom. Researchers working with Scottish criminal law after 2009 must supplement these sources accordingly.

Jurisdictional Note
The Court of Justiciary is purely a Scottish institution with no counterpart in English, Welsh, or Northern Irish law. Researchers applying English criminal law frameworks to Scottish sources, or vice versa, risk fundamental misreadings. The court's criminal finality rule — historically excluding appeal to any court above it in criminal matters — represents a structural divergence from English practice that persisted for centuries and shaped Scots criminal procedure in ways that still distinguish it from English law.
