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 Originally made under an Act of the Parliament of Scotland of 1532, the modern power to make Acts of Sederunt is largely derived from the Courts Reform (Scotland) Act 2014.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 and submitted to the Court of Session for approval.
