UK Administrative Law
Constitutional Foundations of Judicial Review
UK administrative law centres on the judicial review of administrative action by public bodies. Unlike many jurisdictions, the United Kingdom lacks a codified constitution and a dedicated system of administrative courts. Instead, judicial review is exercised by the ordinary courts under the common law, guided by constitutional principles of parliamentary sovereignty, the rule of law, and the separation of powers. The foundational doctrines of UK administrative law have been developed incrementally through judicial decisions, with significant legislative intervention in the form of the Human Rights Act 1998 and the Constitutional Reform Act 2005.
The traditional justification for judicial review is the ultra vires doctrine: when a public body acts beyond the legal powers conferred upon it by Parliament, the courts intervene to ensure that administrative action remains within the boundaries set by the enabling statute. Under this theory, judicial review enforces Parliament’s intention rather than imposing common law limits on executive power. The ultra vires doctrine provides a principled basis for judicial intervention consistent with the constitutional principle of parliamentary sovereignty.
The modified ultra vires theory acknowledges that Parliament often legislates in broad terms and that the common law supplies the content of procedural fairness and reasonableness. Under this view, Parliament legislates against the background assumption that the courts will enforce fundamental common law standards of justice and rationality. The common law theory of judicial review, advanced by Sir John Laws and others, rejects the notion that judicial review derives from legislative intent, arguing instead that the courts develop and enforce minimum standards of good administration as an inherent function of the common law, subject only to clear statutory exclusion. This debate reflects deeper constitutional questions about the source and limits of judicial authority in a system without a written constitution.
Grounds for Judicial Review
The modern classification of grounds for judicial review originates from Lord Diplock’s speech in Council of Civil Service Unions v. Minister for the Civil Service (1985) — the GCHQ case. Lord Diplock identified three heads of review: illegality, irrationality, and procedural impropriety, with proportionality as a potential fourth ground.
Illegality encompasses errors of law, errors of fact going to jurisdiction, and the misuse of discretionary powers. The development of the law on errors of law is dominated by Anisminic Ltd. v. Foreign Compensation Commission (1969), in which the House of Lords held that any error of law by a tribunal or decision-maker renders the decision a nullity, collapsing the traditional distinction between jurisdictional and non-jurisdictional errors. Before Anisminic, only errors of law that went to the tribunal’s jurisdiction were reviewable; errors of law within jurisdiction were not. The House of Lords held that the distinction was artificial and that any misdirection in law that caused the decision-maker to ask the wrong question, consider irrelevant matters, or fail to consider relevant matters went to jurisdiction. Subsequent cases have confirmed that, for practical purposes, all errors of law by public bodies are reviewable.
Illegality also includes the improper exercise of discretionary powers. A decision-maker must not fetter discretion by rigidly applying a policy without considering individual circumstances, must not delegate authority without statutory authorisation, must exercise powers for the purposes for which they were conferred, and must not take into account irrelevant considerations or fail to take into account relevant ones. These principles derive from cases such as Padfield v. Minister of Agriculture (1968), where the House of Lords held that a minister’s refusal to appoint a committee of investigation was unlawful because it frustrated the policy of the governing statute.
Irrationality — or Wednesday unreasonableness, derived from Associated Provincial Picture Houses v. Wednesbury Corporation (1948) — is the second head of review. Lord Greene MR articulated the standard that a decision is unreasonable only if it is so unreasonable that no reasonable authority could ever have come to it. The Wednesbury standard sets a high threshold, requiring a decision that is irrational, perverse, or absurd. The standard reflects judicial deference to administrative discretion in matters of policy and judgment, but its intensity varies with context: the more fundamental the right affected, the more rigorous the review, a principle sometimes described as anxious scrutiny.
Procedural impropriety encompasses two distinct categories: breach of the common law duty of fair hearing (the rule against bias and the right to a fair procedure) and breach of statutory procedural requirements. The common law duty of fair hearing requires that decision-makers be impartial and that affected persons be given an adequate opportunity to present their case. The rule against bias requires that decision-makers have no personal interest in the outcome and that there be no real possibility of bias, as articulated in Porter v. Magill (2002), where the House of Lords adopted the test of whether a fair-minded and informed observer would conclude there was a real possibility of bias.
Proportionality has developed as a distinctly different ground of review since the Human Rights Act 1998, which incorporated the European Convention on Human Rights into domestic law. Proportionality requires that administrative action interfering with Convention rights be rationally connected to a legitimate aim, be necessary (using the least restrictive means), and strike a fair balance between individual rights and public interests. The question of whether proportionality has displaced Wednesbury outside the Convention context was considered in Pham v. Secretary of State for the Home Department (2015) and R (Keyu) v. Secretary of State for Foreign and Commonwealth Affairs (2015). In Pham, the Supreme Court left open the possibility that proportionality could apply to common law fundamental rights, while Keyu held that proportionality had not yet replaced Wednesbury for non-Convention cases. The status of proportionality as a general ground of review remains an evolving area of UK administrative law.
Procedural Exclusivity
The procedural exclusivity principle, established in O’Reilly v. Mackman (1983), requires that claims seeking to enforce public law rights must be brought through the judicial review procedure rather than by ordinary action. The House of Lords held that it would be an abuse of process to circumvent the procedural protections of judicial review — including the requirement for leave (permission), the shorter limitation period, and the requirement to exhaust alternative remedies — by bringing a public law claim through private law procedures.
The court recognised exceptions where the invalidity of a public law decision arises collaterally in private law proceedings. In Clark v. University of Lincolnshire and Humberside (2000), the Court of Appeal held that the procedural exclusivity rule is not absolute and that the court retains discretion to permit a claim to proceed by ordinary action where no prejudice results. The modern approach is pragmatic rather than rigid, focusing on whether the use of ordinary procedure would circumvent protections designed for public law litigation.
Standing Requirements
Standing in judicial review requires that the claimant have sufficient interest in the matter to which the application relates, as provided by section 31 of the Senior Courts Act 1981. The threshold is generous: courts have recognised standing for pressure groups, public interest litigants, and individual citizens challenging administrative action that affects the wider public. In R v. Inspectorate of Pollution, ex parte Greenpeace (1994), the court recognised Greenpeace’s standing based on its expertise and representative capacity. In R v. Secretary of State for Foreign Affairs, ex parte World Development Movement (1995), the court recognised standing for a pressure group challenging the legality of aid to Malaysia. The courts balance the requirement of sufficient interest against the need to prevent busybodies and vexatious litigants from abusing the process.
The Ombudsman System
The UK has developed an extensive ombudsman system as an alternative mechanism for addressing administrative grievances. The Parliamentary Ombudsman (now the Parliamentary and Health Service Ombudsman), established under the Parliamentary Commissioner Act 1967, investigates complaints of maladministration by central government departments. Maladministration includes delay, rudeness, bias, failure to follow procedures, and misleading advice. The Ombudsman reports to Parliament rather than the executive, preserving the constitutional principle of ministerial accountability.
The Local Government Ombudsman (now the Local Government and Social Care Ombudsman) investigates complaints against local authorities, while the Public Services Ombudsman for Wales, the Scottish Public Services Ombudsman, and the Northern Ireland Public Services Ombudsman cover their respective jurisdictions. The ombudsman system provides a flexible, inexpensive, and non-legalistic mechanism for holding administrators accountable, though ombudsmen lack the power to make binding determinations and rely on persuasion and parliamentary pressure to secure compliance.
The Tribunal System
The UK tribunal system, restructured by the Tribunals, Courts and Enforcement Act 2007, provides specialised administrative adjudication for a wide range of disputes between citizens and the state. The First-tier Tribunal handles cases in areas including social security, immigration, tax, mental health, and special educational needs. The Upper Tribunal hears appeals and exercises supervisory jurisdiction. Tribunals combine legal expertise with specialist knowledge of their subject areas, providing accessible and proportionate justice for administrative disputes. The tribunal system has largely replaced the earlier patchwork of independent tribunals, creating a coherent structure with independent judicial leadership under the Senior President of Tribunals.
