Trial by jury in Scotland in the context of Solemn procedure

A sheriff court (Scottish Gaelic: Cùirt an t-Siorraim) is the principal local civil and criminal court in Scotland, with exclusive jurisdiction over all civil cases with a monetary value up to £100,000, and with the jurisdiction to hear any criminal case except treason, murder, and rape, which are in the exclusive jurisdiction of the High Court of Justiciary. Though the sheriff courts have concurrent jurisdiction with the High Court over armed robbery, drug trafficking, and sexual offences involving children, the vast majority of these cases are heard by the High Court. Each court serves a sheriff court district within one of the six sheriffdoms of Scotland. Each sheriff court is presided over by a sheriff, who is a legally qualified judge, and part of the judiciary of Scotland.

Sheriff courts hear civil cases as a bench trial without a jury, and make determinations and judgments alone. However, the specialist all-Scotland Sheriff Personal Injury Court (based in Edinburgh) has the ability to hear cases with a jury of twelve. Sheriff courts hear criminal trials on complaint as a bench trial for summary offences, and as a trial with a jury of fifteen for indictable offences. Where a person is convicted following a case heard on complaint they can be sentenced to a maximum of twelve months imprisonment and/or a £10,000 fine, and in solemn cases, 5 years imprisonment or an unlimited fine.

The High Court of Justiciary (Scottish Gaelic: Àrd-chùirt a' Cheartais) is the supreme criminal court in Scotland. The High Court is both a trial court and a court of appeal. As a trial court, the High Court sits on circuit at Parliament House or in the adjacent Justiciary Building (the former Sheriff Court building) in the Old Town in Edinburgh, or in dedicated buildings in Glasgow and Aberdeen. The High Court sometimes sits in various smaller towns in Scotland, where it uses the local sheriff court building. As an appeal court, the High Court sits only in Edinburgh. On one occasion the High Court of Justiciary sat outside Scotland, at Zeist in the Netherlands during the Pan Am Flight 103 bombing trial, as the Scottish Court in the Netherlands. At Zeist the High Court sat both as a trial court, and an appeal court for the initial appeal by Abdelbaset al-Megrahi.

The president of the High Court is the Lord Justice General, who holds office ex officio by virtue of being Lord President of the Court of Session, and his depute is the Lord Justice Clerk. The remaining judges are the Lords Commissioners of Justiciary, who hold office ex officio by virtue of being appointed as Senators of the College of Justice and judges of the Court of Session. As a court of first instance trials are usually heard with a jury of 15 and a single Lord Commissioner of Justiciary; the jury can convict on a majority verdict. In some cases, such as the trial of Abdelbaset al-Megrahi and Lamin Khalifah Fhimah for the bombing of Pan Am Flight 103, a trial can be heard by a bench of judges alone; sitting without a jury. As an appeal court the hearings are always without a jury, with two judges sitting to hear an appeal against sentence, and three judges sit to hear an appeal against conviction.
