  The United Kingdom does not have a single legal system as Article 19 of the 1706 Treaty of Union provided for the continuation of Scotland's separate legal system. Today the UK has three distinct systems of law: English law, Northern Ireland law and Scots law. A new Supreme Court of the United Kingdom came into being in October 2009 to replace the Appellate Committee of the House of Lords. The Judicial Committee of the Privy Council, including the same members as the Supreme Court, is the highest court of appeal for several independent Commonwealth countries, the British Overseas Territories and the Crown Dependencies.
  
  Both English law, which applies in England and Wales, and Northern Ireland law are based on common law (or case law) principles. It originated in England in the Middle Ages and is the basis for many legal systems around the world. The courts of England and Wales are headed by the Senior Courts of England and Wales, consisting of the Court of Appeal, the High Court of Justice (for civil cases) and the Crown Court (for criminal cases). Scots law is a hybrid system based on common-law and civil-law principles. The chief courts are the Court of Session, for civil cases, and the High Court of Justiciary, for criminal cases. The Supreme Court of the United Kingdom serves as the highest court of appeal for civil cases under Scots law.
  
  Crime in England and Wales increased in the period between 1981 and 1995, though since that peak there has been an overall fall of 66 per cent in recorded crime from 1995 to 2015, according to crime statistics. As of June 2023, the United Kingdom has the highest per-capita incarceration rate in Western Europe.
  
  UK labour laws entitle staff to have a minimum set of employment rights including a minimum wage, a minimum of 28 days annual holiday, parental leave, statutory sick pay and a pension. Same-sex marriage has been legal in England, Scotland, and Wales since 2014, and in Northern Ireland since 2020. LGBT equality in the United Kingdom is considered advanced by modern standards.
