The judges are the same ones who sit in the Court of Session, Scotland's highest civil court. The Court of Session's Lord President is the High Court's Lord Justice-General. Also, the Lord Justice-Clerk holds such an office in both courts. The remaining judges are referred to as Lords Commissioners of Justiciary in the context of this court, but are normally called Lords of Council and Session or Senators of the College of Justice, their Court of Session titles.
The Court has jurisdiction over all crimes in Scotland unless restricted by statute. In practice, however, the Court generally deals with serious crimes such as homicide.
First Instance Jurisdiction
When sitting as a court of the first instance, that is, when hearing a case for the first time rather than on appeal, a single Lord Commissioner of Justiciary presides, and a jury of fifteen individuals is used. Under the Scottish legal system, the jury need not return a unanimous verdict; a majority verdict may also be used.
