The judiciary refers to the body of judges and judicial office-holders responsible for interpreting and applying the law, resolving disputes and overseeing the fair administration of justice. In UK and Irish legal practice, the term is descriptive rather than usually given a single statutory definition, but is widely used in legislation, case law and constitutional commentary. Across England and Wales, Scotland, Northern Ireland and Ireland, the judiciary includes judges in superior and inferior courts (for example, Supreme Court justices, Court of Appeal judges, High Court judges, sheriffs in Scotland, District Judges and equivalent offices), and in some contexts tribunal judges. The judiciary is institutionally independent from the executive and legislature, a core principle underpinning the rule of law, fair trial rights and separation of powers. Judicial independence is protected by constitutional instruments and statutes (for example, the Constitutional Reform Act 2005 in the UK and Articles 34–37 of the Irish Constitution). In practice, references to “the judiciary” commonly arise in discussions of judicial appointments, discipline, recusal, judicial review, constitutional litigation, court reform and access to justice across all four jurisdictions.
