Judicial Independence

Introduction

Judicial independence is a fundamental principle of the United Kingdom constitution. It requires that judges are free from external influence, pressure, or interference in the exercise of their judicial functions. The principle protects the judiciary from the executive and legislative branches of government, ensuring that cases are decided impartially according to law. Judicial independence has been secured through a series of constitutional settlements, beginning with the Act of Settlement 1701 and continuing through the Constitutional Reform Act 2005. The principle is essential to the rule of law and to public confidence in the administration of justice.

The Act of Settlement 1701

The Act of Settlement 1701 was a landmark constitutional statute that established the foundation for judicial independence. Section 3 provided that judges’ commissions were to be made quamdiu se bene gesserint (during good behaviour) rather than durante bene placito (at the monarch’s pleasure), and that judges could only be removed on the address of both Houses of Parliament. This provision was a direct response to the Stuart monarchs’ practice of dismissing judges who gave judgments contrary to the Crown’s interests. The Act thus removed the monarch’s power to dismiss judges at will and gave Parliament the sole power of removal. The Act also required that judges’ salaries be “ascertained and established” rather than variable at the monarch’s discretion. These protections ensured that judges could decide cases according to law without fear of reprisal. The procedure for removal—requiring a resolution passed by both Houses of Parliament—has been used only once in modern times, for Sir Jonah Barrington (1830), and no judge has been removed in the United Kingdom since 1830.

The Constitutional Reform Act 2005

The Constitutional Reform Act 2005 significantly strengthened judicial independence. Section 1 of the Act imposes a statutory duty on the Lord Chancellor and other ministers of the Crown to “uphold the continued independence of the judiciary.” The Act created the Judicial Appointments Commission to remove patronage from judicial appointments, transferred the responsibility for judicial discipline from the Lord Chancellor to the Judicial Conduct Investigations Office, and established the Supreme Court as a separate institution, removing the judiciary from the House of Lords. The Act also provided that the Lord Chancellor must have regard to the need to defend judicial independence, to ensure that judges have the support necessary to carry out their functions, and to ensure that the Lord Chancellor’s own actions do not prejudice judicial independence. The Act’s guarantees are reinforced by a constitutional oaths requirement for the Lord Chancellor.

Security of Tenure

Security of judicial tenure is protected by the Act of Settlement 1701, the Senior Courts Act 1981, and the Constitutional Reform Act 2005. Judges of the Senior Courts (High Court and Court of Appeal) hold office during good behaviour and can only be removed by the monarch on an address presented by both Houses of Parliament. Supreme Court Justices hold office on the same terms, subject to a mandatory retirement age of 75 (reduced from 70 by the Judicial Pensions and Retirement Act 1993). Lords of Appeal in Ordinary (the former Law Lords) held office for life, but all judges appointed after 1995 are subject to a compulsory retirement age. The retirement age for Senior Courts judges was reduced to 70 by the Judicial Pensions and Retirement Act 1993, with provision for extending tenure for up to one year in the public interest. The Lord Chief Justice is the head of the judiciary in England and Wales and represents judicial views to Parliament and the government. The Lord President performs a similar role in Scotland.

Judicial Appointments Commission

The Judicial Appointments Commission (JAC) was established by the Constitutional Reform Act 2005 to make recommendations for judicial appointments to the Lord Chancellor. The Commission is an independent non-departmental public body, composed of commissioners drawn from the judiciary, the legal profession, and the lay public. The requirement to appoint on merit is central: section 63 of the Act provides that selection must be “solely on merit,” and that the Commission must have regard to the need to encourage diversity in the pool of candidates. The Lord Chancellor retains a limited power to reject or require reconsideration of a JAC recommendation but cannot substitute his own candidate. The Judicial Appointments Board for Scotland and the Northern Ireland Judicial Appointments Commission perform analogous functions in their jurisdictions. The JAC’s processes have been the subject of litigation, including challenges to the lawfulness of the requirement to appoint on merit where candidates are equally qualified.

The Lord Chancellor’s Role Reform

The Constitutional Reform Act 2005 fundamentally reformed the role of the Lord Chancellor. Historically, the Lord Chancellor was head of the judiciary, speaker of the House of Lords, and a Cabinet minister—a triple role that created a problematic fusion of powers. The Act ended the Lord Chancellor’s role as head of the judiciary (transferring this to the Lord Chief Justice), ended the Lord Chancellor’s role as speaker of the House of Lords (transferring this to the Lord Speaker), and imposed a statutory duty to uphold judicial independence. The Act also provided that the Lord Chancellor could no longer be a judge, removing the judicial element of the office entirely. The Lord Chancellor’s oath requires the office-holder to swear to “respect the rule of law, defend the independence of the judiciary, and discharge my duty to ensure the provision of resources for the efficient and effective support of the courts.” Despite the reform, the Lord Chancellor remains a senior Cabinet minister and continues to have responsibility for the courts system, legal aid, and the administration of justice.

The Separation of Powers in Practice

Judicial independence is reinforced by a range of constitutional conventions and statutory provisions. The sub judice rule prevents Parliament from debating matters that are before the courts. The contempt of court doctrine protects judicial proceedings from interference or prejudgment. The courts’ power to control their own procedure is an aspect of their independence. The Salaries of judges are charged on the Consolidated Fund, meaning they do not require annual parliamentary authorisation and are not subject to government cuts. The Lord Chief Justice and other senior judges are consulted on matters affecting the judiciary. The Judicial Executive Board and the Judicial Council manage the administration of the courts. The Judicial College provides training for judges. The Sentencing Council issues guidelines for sentencing. These institutional arrangements ensure that the judiciary has the capacity to function independently and to resist pressure from the other branches of government.

Conclusion

Judicial independence is a cornerstone of the UK constitution, protected by a framework of statutes, conventions, and institutional arrangements that stretch from the Act of Settlement 1701 to the Constitutional Reform Act 2005. The principle ensures that judges can decide cases according to law, without fear of reprisal from the executive or the legislature. The reforms of the Constitutional Reform Act 2005—particularly the creation of the Supreme Court and the Judicial Appointments Commission—addressed long-standing concerns about the fusion of powers and placed judicial independence on a more secure constitutional footing. Judicial independence is not absolute: judges are accountable to the public through the appeals process, through the Judicial Appointments and Conduct Ombudsman, and through the impeachment process. But the principle that judges must be free from external interference in the exercise of their judicial functions is fundamental to the rule of law.
