Courts Reform (Scotland) Act 2014 in the context of Act of the Scottish Parliament

The courts of Scotland (Scottish Gaelic: Cùirtean na h-Alba) are responsible for administration of justice in Scotland, under statutory, common law and equitable provisions within Scots law. The courts are presided over by the judiciary of Scotland, who are the various judicial office holders responsible for issuing judgments, ensuring fair trials, and deciding on sentencing. The Court of Session is the supreme civil court of Scotland, subject to appeals to the Supreme Court of the United Kingdom, and the High Court of Justiciary is the supreme criminal court, which is only subject to the authority of the Supreme Court of the United Kingdom on devolution issues and human rights compatibility issues.

The judiciary of Scotland, except the Lord Lyon King of Arms, are united under the leadership and authority of the Lord President and Lord Justice General, who is the president of the Court of Session and High Court of Justiciary. The Court of Session has the authority, under the Courts Reform (Scotland) Act 2014, to regulate civil procedure through passing subordinate legislation knows as Acts of Sederunt, and the High Court of Justiciary has the authority to regulate criminal procedure through passing Acts of Adjournal. Both Acts of Sederunt and Acts of Adjournal have the capacity to amend primary legislation where it deals with civil or criminal procedure respectively.

In Scotland a sheriff principal (pl. sheriffs principal) (Scottish Gaelic: àrd-siorram) is a judge in charge of a sheriffdom with judicial, quasi-judicial, and administrative responsibilities. Sheriffs principal have been part of the judiciary of Scotland since the 11th century. Sheriffs principal were originally appointed by the monarch of Scotland, and evolved into a heritable jurisdiction before appointment was again vested in the Crown and the monarch of the United Kingdom following the passage of the Heritable Jurisdictions (Scotland) Act 1746.

Under the Sheriff Courts (Scotland) Act 1971 (as amended), each sheriff principal is appointed by the monarch of the United Kingdom on the advice of the First Minister of Scotland, who is advised by the Judicial Appointments Board for Scotland. As of May 2017 there were six sheriffs principal, each of whom has responsibility not only as a judge, but for the administration of justice in their respective sheriffdoms. Sheriffs principal have to ensure the effective running of the sheriff courts and justice of the peace courts within their jurisdiction. Following the passage of both the Courts Reform (Scotland) Act 2014 and the Judiciary and Courts (Scotland) Act 2008, sheriffs principal are subject to the authority and direction of the Lord President of the Court of Session as Head of the Judiciary of Scotland.

An Act of Sederunt (/səˈdɛrənt/ sə-DERR-ənt; meaning a meeting or sitting of a court) is secondary legislation made by the Court of Session, the supreme civil court of Scotland, to regulate the proceedings of Scottish courts and tribunals hearing civil matters. Originally made under an Act of the Parliament of Scotland of 1532, the modern power to make Acts of Sederunt is largely derived from the Courts Reform (Scotland) Act 2014. Since 2013, draft Acts have also been prepared by the Scottish Civil Justice Council and submitted to the Court of Session for approval.

Following Scottish devolution and the establishment of the Scottish Parliament, Acts of Sederunt are made as Scottish statutory instruments. Previously, Acts were made as United Kingdom statutory instruments, and before that were a separate class of legislation.
