Judicial Review: Irrationality and Proportionality

Overview of Judicial Review Claims

A Judicial Review (JR) claim involves navigating two distinct phases: admissibility and substantive review. Each stage has specific legal thresholds and categories.

Admissibility and Procedural Hurdles

Before a court considers the merits of a claim, the following must be satisfied:

  • Public Law: The decision must involve a matter of public law.

  • Public Authority: The decision-maker must be a public authority.

  • Standing: The applicant must have a sufficient interest in the matter.

  • Time: Claims must be filed promptly and within specific time limits.

  • Ouster Clause: The court must determine if any statutory provisions attempt to exclude the court's jurisdiction.

Substantive Review Grounds

If admissible, the claim is reviewed based on three primary grounds:

  1. Illegality: The decision-maker must understand correctly the law that regulates their decision-making power and must give effect to it.

  2. Irrationality: Also known as "unreasonableness."

  3. Procedural Impropriety: Failure to observe basic rules of natural justice or failure to act with procedural fairness.

Available Remedies

  • Damages: Monetary compensation.

  • Quashing order: Invalidates the original decision.

  • Mandating order: Compels the authority to perform its duty.

  • Prohibiting Order: Prevents the authority from taking an unlawful action.

  • Declaration: A formal statement of the legal position.

  • Injunction: An order to do or refrain from doing a specific act.

  • Clarification of a question of law: Formal guidance on legal interpretation.

Irrationality (Wednesbury Unreasonableness)

Irrationality is established as the second substantive ground for judicial review, as outlined by Lord Diplock in the GCHQ case.

Definitions and Interpretation

  • Interchangeability: The House of Lords confirmed in Re Duffy (FC) (Northern Ireland) [2008] UKHL 4 that the terms "irrationality" and "unreasonableness" are interchangeable.

  • Lord Diplock’s Definition (GCHQ Case): He defined irrationality as: "By 'irrationality' I mean what can now be succinctly referred to as 'Wednesbury unreasonableness'. It applies to a decision which is so outrageous in its defiance of logic or of accepted moral standards that no sensible person who had applied his mind to the question to be decided could have arrived at it."

The Wednesbury Case: Associated Provincial Picture Houses Ltd v Wednesbury Corporation [1948]

  • Facts: Under the Sunday Entertainments Act 1932, the Wednesbury Corporation (WC) had the statutory power to grant cinema licenses for Sunday screenings "subject to such conditions as the authority think fit to impose." WC granted a license to the Applicant on the condition that no children under the age of 1515 were admitted. The Applicant challenged this condition as "unreasonable."

  • Outcome: The High Court rejected the claim. On appeal, the Court of Appeal (CoA) upheld the original decision.

  • Legal Principle: Lord Greene MR established that for the court to interfere, the conclusion must be: "…a conclusion so unreasonable that no reasonable authority could ever have come to it."

The High Threshold of Irrationality

Irrationality is a notoriously difficult ground to prove in court because the standard required is exceptionally high.

  • Rare Success: Claims often fail because it is rare for a decision to be "so outrageous in its defiance of logic" that no sensible person would have made it.

  • Example: Devon County Council v George [1989]: The council had a statutory obligation to provide free transport for children living 33 miles away from school. They withdrew transport for an 88-year-old boy living approximately 2.92.9 miles away. The House of Lords held this was not "unreasonable" in the Wednesbury sense.

  • Additional Case Law:

    • Ex parte Nottinghamshire County Council [1986] AC 240

    • Ex parte Smith [1996] Q1 517: Though it failed under Wednesbury, it was successfully challenged at the ECtHR in Smith v UK (2000) 29 EHRR 493 for breaching Article 8, leading the UK government to lift the ban on homosexuals in the military.

    • R (on the application of Hoareau and Bancoult) v SSFCA [2020] EWCA Civ 1010

Judicial Deference and Constitutional Limits

The high threshold for irrationality exists to maintain a constitutional balance between the judiciary and the executive.

Legality vs. Merits

  • The purpose of JR is to review the "legality" of actions, not the "merits."

  • Establishing irrationality too easily would result in a "merits-based review," where judges usurp the role of the executive by substituting their own views for those of the decision-maker.

Judicial Reluctance and Light Scrutiny

  • Exceptional Circumstances: Judges only intervene in exceptional cases to avoid overstepping. Lord Scarman in R v Secretary of State for the Environment, ex parte Nottinghamshire County Council [1986] stated: "I cannot accept that it is constitutionally appropriate, save in very exceptional circumstances, for the courts to intervene on the ground of 'unreasonableness'."

  • Resource Allocation: Courts apply "light scrutiny" and are reluctant to quash decisions regarding the allocation of resources (e.g., R (Luton and others) v Secretary of State for Education [2011]).

  • Specialist Knowledge and Political Judgment: In R (Campaign Against Arms Trade) v SSIT [2017], authorising arms exports to Saudi Arabia was deemed a "matter of political judgment" involving the government's "considerable specialist knowledge."

  • Usurpation of Power: Lord Ackner in R v SSHD, ex parte Brind [1991] warned that substituting a judicial view on the merits would be a "wrongful usurpation of power."

Criticisms of the Wednesbury Test

Scholars such as Jowell and Lester argue for the abandonment of irrationality/Wednesbury unreasonableness based on several factors:

  • Legality Concern: Administrative unreasonableness should not alone justify court intervention; courts should focus strictly on legality.

  • Tautology: The test is criticized for being circular: it focuses on unreasonableness without ever defining what "reasonableness" actually is.

Proportionality

Proportionality is a distinct ground of review primarily used in the context of human rights, originating from European legal traditions.

Context: Human Rights Act 1998

  • The HRA 1998 incorporates the European Convention on Human Rights (ECHR) into UK law.

  • Qualified Rights: Many ECHR rights (e.g., Article 8—Right to private and family life) are not absolute and can be limited or "qualified" for public interest (e.g., protecting the public from terrorist attacks).

  • Requirement: When a public authority infringes on these rights, it must prove the action was "proportionate," not just "reasonable."

The Proportionality Test (de Freitas [1999])

According to de Freitas [1999] 1 AC 69, a qualification of a fundamental right is proportionate ONLY if all four of these questions are answered with a "yes":

  1. Legitimate Aim: Was there a legitimate aim that justified qualifying the rights?

  2. Rational Connection: Was the action taken for the purposes of securing that legitimate aim?

  3. Necessity: Did the authority go no further than was strictly necessary to achieve the aim?

  4. Fair Balance: Has a fair balance been struck between the individual's rights and the wider public interest?

Key Case: R (Daly) v Secretary of State for the Home Department [2001]

  • Facts: A blanket policy under the Prison Act 1952 allowed prison officers to search cells in the prisoner's absence and examine correspondence between prisoners and their legal advisors. Daly challenged this under Article 8 ECHR (privacy).

  • Outcome: The House of Lords held the policy was NOT proportionate.

  • Analysis: While there was a legitimate aim and a connection to securing it, the policy failed at step 3: it went further than was strictly necessary.

Modern Developments in Proportionality

  • Pham v SSHD [2015] UKSC 19: The Supreme Court indicated that when a case has particularly important consequences for the claimant, proportionality principles can apply beyond existing categories. The court used the metaphor: "You should not use a sledgehammer to crack nuts, when a nutcracker will do."

Relationship Between Irrationality and Proportionality

Current Co-existence

  • Overlaps: Both grounds require the court to look beyond simple legality into the nature of the authority's behavior.

  • Division of Labor: Currently, the two tests exist alongside each other. Proportionality is generally reserved for human rights cases (R (Association of British Civilian Internees: Far East Region) v Secretary of State for Defence [2003]).

Future Outlook

  • Potential Replacement: Several judges have suggested that proportionality might eventually replace Wednesbury unreasonableness entirely. This view was noted by Lord Cooke in R (Daly) and Lord Slynn in R (Alconbury Developments Ltd) v Secretary of State for the Environment [2001].

  • Status Quo: Despite these suggestions, the unreasonableness test remains good law and continues to be used by courts, as seen in R (D & others) v Parole Board [2018] EWHC 694.
