Introduction to United Kingdom's Legal System
Type of Legal System
The United Kingdom of Great Britain and Northern Ireland is the collective name of four countries, England, Wales, Scotland and Northern Ireland. The four separate countries were united under a single Parliament through a series of Acts of Union. The United Kingdom has recently undergone a period of devolution with the creation of the Scottish Parliament, the National Assembly for Wales, and the Northern Ireland Assembly that have the authority to legislate in defined areas.
The legal system in the United Kingdom is common law based, with origins from Roman law and considerable Anglo-Saxon influence. The judiciary interprets statutes passed by Parliament, and follows its own precedence. Statutory laws consist of Acts of Parliament (primary legislation) and subordinate legislation, which predominately consists of statutory instruments (also known as regulations, secondary or delegated legislation) made by Parliament. The common law consists of judicial decisions from the higher courts and the “decisions of any of the courts or tribunals of the United Kingdom in construing legislation.”

Official Sources of Law
Official Acts of Parliament and secondary legislation are currently published through The Stationary Office (external link).
The Office of Public Sector Information (external link) publishes the official version of online legislation for the United Kingdom. The following resources are available from its website:
- Acts of Parliament: 1988 – current;
- Statutory instruments: 1987 – current;
- Scottish Acts of Parliament and Statutory Instruments: 1999 – current;
- Scottish Statutory Instruments: 1999 – current;
- Welsh Statutory Instruments: 1999 – current;
- Acts of the Northern Ireland Assembly: 2000 – current;
- Northern Ireland Statutory Rules (SRs): 2000 – current
This legislation is printed “as published” on the website and not codified or consolidated to take into account amendments or repeals or the laws entry into force. As such, while this web site is an official source for law, it is often not an accurate representation of the current status of the law.
An “official revised edition of the primary legislation” in the UK is available online through the target="_blank" class="external"Ministry of Justice Statute Law Database (external link), although the revised version of the legislation typically is a couple of years behind.
There are a large number of commercial case reporters in the United Kingdom. The Incorporated Council of Law Reporting for England and Wales (external link), a charitable organization, publishes the official Law Reports, the most authoritative reports of cases in England and Wales. When a case is reported in the Law Reports, a Practice Direction requires that this source be cited, and that other reporters only be used in the event that the case has not been published in the Law Reports.
The official source for cases from the Court of Session and High Court of Justiciary, Scotland’s highest civil and criminal court, respectively are The Session Cases. These reports are published by the Scottish Council of Law Reporting (external link), a charitable body, and have been recognized as the most authoritative reporter for cases as the court revises the judgments published therein. The Session Cases are published in 6 parts throughout the year.
