The legislatures of the United Kingdom are derived from a number of different sources. The parliament of the United Kingdom is the supreme legislative body for the United Kingdom and the British overseas territories with Scotland, Wales and Northern Ireland each having their own devolved legislatures. Each of the three major jurisdictions of the United Kingdom has its own laws and legal system.
A statutory instrument (SI) is the principal form in which delegated legislation is made in Great Britain.
In law, coming into force or entry into force is the process by which legislation, regulations, treaties and other legal instruments come to have legal force and effect. The term is closely related to the date of this transition. The point at which such instrument comes into effect may be set out in the instrument itself, or after the lapse of a certain period, or upon the happening of a certain event, such as a proclamation or an objective event, such as the birth, marriage, reaching a particular age or death of a certain person. On rare occasions, the effective date of a law may be backdated to a date before the enactment.
A Scottish statutory instrument is subordinate legislation made by the Scottish Ministers, as well as subordinate legislation made by public bodies using powers provided to be exercisable by Scottish statutory instrument. SSIs are the main form of subordinate legislation in Scotland, being used by default to exercise powers delegated to the Scottish Ministers, the Lord Advocate, the High Court of Justiciary, the Court of Session, and the Queen-in-Council.
The United Nations Act 1946 is an Act of the Parliament of the United Kingdom which enables His Majesty's Government to implement resolutions under Article 41 of the United Nations Charter as Orders in Council. Thus Parliament delegated the power to enact such resolutions without the approval of Parliament. However, the prospective Order must be laid before either Parliament or the Scottish Parliament. A similar mechanism was later used in the European Communities Act 1972 and the Terrorist Asset-Freezing etc. Act 2010.
In many countries, a statutory instrument is a form of delegated legislation.
An Act of Sederunt 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 Originally made under an Act of the Parliament of Scotland of 1532, the modern power to make Acts of Sederunt is largely derived from the Courts Reform (Scotland) Act 2014.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.
An Act of Adjournal is secondary legislation made by the High Court of Justiciary, the supreme criminal court of Scotland, to regulate the proceedings of Scottish courts hearing criminal matters. Now primarily derived from the Criminal Procedure (Scotland) Act 1995, the original power to create Acts of Adjournal is derived from an Act of the Parliament of Scotland of 1672. Before promulgation, Acts of Adjournal are reviewed and may be commented upon by the Criminal Courts Rules Council.
An act of the Scottish Parliament is primary legislation made by the Scottish Parliament. The power to create acts was conferred to the Parliament by section 28 of the Scotland Act 1998 following the successful 1997 referendum on devolution.
