Judicial review is a critical mechanism in the UK legal system that allows individuals, businesses, and organisations to challenge the lawfulness of decisions, actions, or failures to act by public bodies. It plays a key role in holding government departments, local authorities, NHS bodies, regulators, and other public authorities accountable. This guide explains the essentials and common issues.
Important Note: This article is for general information only and does not constitute legal advice. Judicial review is complex, time-sensitive, and often costly. Always seek specialist legal advice for your specific situation. Rules can change, so check official sources like GOV.UK or the judiciary website.
What Is Judicial Review?
Judicial review is a court process in which a judge reviews the lawfulness of a decision, action, or inaction by a public body exercising a public function. It focuses on how the decision was made — not whether it was the “right” or “best” decision on the merits.
The court supervises public authorities to ensure they act within their legal powers, follow fair procedures, and make rational decisions. It is governed primarily by the Civil Procedure Rules (Part 54) and is usually heard in the Administrative Court (part of the High Court).
Successful judicial reviews can lead to the decision being quashed, but the public body may often remake the same decision lawfully.
When Can You Apply?
You can apply for judicial review when:
- A public body has made a decision, taken an action, or failed to act in a way that affects you or the public interest.
- You have exhausted any available alternative remedies (such as internal appeals or complaints procedures), unless there is good reason not to.
- The matter involves a public law issue (not purely private disputes).
It is a remedy of last resort and must generally be used promptly.
Grounds for Judicial Review
The main grounds, often overlapping, are:
- Illegality: The public body acted outside its powers (ultra vires), misapplied the law, took into account irrelevant considerations, or ignored relevant ones.
- Irrationality (or unreasonableness): The decision is so unreasonable that no rational authority could have made it (the “Wednesbury” test).
- Procedural Impropriety: Failure to follow required procedures, breach of natural justice, bias, or lack of fairness (e.g., not giving someone a chance to be heard).
Other grounds can include breach of legitimate expectation or human rights incompatibility under the Human Rights Act 1998.
Who Can Bring a Claim?
You must have sufficient interest (standing) in the matter. This usually includes:
- Individuals directly affected by the decision.
- Organisations or pressure groups with a genuine interest, especially where broader public interest is involved.
The court has discretion and will consider the nature of the claimant’s interest.
Time Limits for Applications
Claims must be brought promptly and, in any event, within three months of the date when the grounds first arose. Even within three months, undue delay can lead to refusal.
Shorter limits apply in some cases:
- Planning decisions: Usually 6 weeks.
- Public procurement: Often 30 days.
Time limits are strict. Extensions are possible but not guaranteed and require strong justification.
The Judicial Review Process
- Pre-Action Protocol: Send a detailed letter before claim to the public body, giving them a chance to resolve the issue.
- Apply for Permission: File Form N461 with the Administrative Court, including grounds and evidence. The court decides on the papers (or at a hearing) whether the claim is “arguable.”
- Substantive Hearing: If permission is granted, full arguments are heard, often with detailed evidence and skeleton arguments.
- Judgment and Remedies: The court issues its decision.
The process can take several months; urgent cases (e.g., involving removal or serious harm) can be expedited.
Common Legal Challenges
Judicial review is frequently used in areas such as:
- Immigration and asylum decisions (e.g., Home Office refusals).
- Planning and environmental permissions.
- Benefits and welfare decisions.
- Education, healthcare, and local authority services.
- Government policy and secondary legislation.
Common issues include failure to follow policy, inadequate reasoning, or breaches of equality duties.
Possible Court Outcomes
If the claim succeeds, remedies may include:
- Quashing order: The decision is set aside.
- Mandatory order: Requiring the body to do something.
- Prohibiting order: Preventing an unlawful action.
- Declaration: Stating the legal position.
The court rarely substitutes its own decision; the public body usually reconsiders the matter lawfully.
Costs and Funding Options
Judicial review can be expensive. The general rule is “costs follow the event” — the losing party pays the winner’s costs.
Funding options:
- Legal Aid: Available for eligible individuals on low income with merit in the case (subject to strict criteria).
- Protective Costs Orders (PCOs): Can limit or cap exposure to the other side’s costs in public interest cases.
- Conditional Fee Agreements (“no win, no fee”) in some cases.
- Self-funding or crowdfunding for strong public interest matters.
Early settlement via pre-action can significantly reduce costs.
Getting Legal Advice
Due to the strict time limits, procedural complexity, and high stakes, specialist public law solicitors or barristers are essential. Look for regulated practitioners with judicial review experience. Organisations like the Public Law Project or local law centres can provide initial guidance.
Conclusion
Judicial review is a powerful tool for ensuring public bodies act lawfully, but success depends on strong grounds, prompt action, and robust evidence. Many claims settle at the pre-action stage, while others highlight important issues of accountability.
