How to Apply for Judicial Review: A Step-by-Step Guide

Judicial review is a legal process that enables individuals, organisations or businesses to challenge decisions, actions or failures to act by public bodies when those decisions are unlawful, unreasonable or procedurally unfair. It is a cornerstone of public law in England and Wales and ensures that public authorities act within the scope of law and respect fundamental legal rights. Judicial review is not a remedy for simply disagreeing with a decision; it is a mechanism to challenge lawfulness and fairness.

This article explains judicial review step‑by‑step, including eligibility, time limits, pre‑action requirements, how to start a claim, the permission stage, hearings, possible outcomes, risks, and common questions.

What Is Judicial Review?

Judicial review is a civil court process in the Administrative Court (part of the High Court) where a judge examines whether a decision or action by a public body is lawful. It can apply to decisions of:

• central or local government departments
• public authorities (for example, local councils or regulators)
• courts or tribunals (in limited circumstances)
• other bodies exercising public functions.

The court considers the lawfulness of the decision-making process, not whether the decision was simply wrong in judgment. Common grounds include:

• Illegality: the public body lacked power to make the decision.
• Irrationality: the decision is so unreasonable that no reasonable authority could have made it (sometimes called ‘Wednesbury unreasonableness').
• Procedural unfairness: the process was unfair or breached rules of natural justice.

Who Can Apply

To bring a judicial review claim you must have ‘sufficient interest' in the matter. This means your own rights or interests must be directly affected by the decision. Individuals, community groups and, in some cases, organisations can have sufficient interest. The court will assess this on a case‑by‑case basis.

Time Limits

Time limits in judicial review are strict:

• General rule: file the claim promptly and within three months from the date the decision took effect.
• Planning decisions: claims must usually be filed within six weeks.
• Other statutory schemes may have shorter limits.

If you delay unreasonably, the court may refuse permission even if you file within the statutory period.

Pre‑Action Protocol

Before filing formal court papers, you must follow the Pre‑Action Protocol for Judicial Review, part of the Civil Procedure Rules. This is an important procedural step which requires you to:

1. Send a Letter Before Claim setting out your case.
2. Allow the authority to respond.
3. Consider whether your claim can be resolved without going to court.

Failing to follow the protocol can lead to the court imposing costs penalties or refusing relief.

How to Start a Judicial Review Claim

Choosing the Correct Court and Form

Most judicial review claims are started in the Administrative Court of the High Court. For certain tribunal decisions, especially appeals or specific tribunal decisions, there are separate forms and the Upper Tribunal may have jurisdiction.

The main claim form used in the Administrative Court is Form N461. This form asks for details of:

• the public authority you are challenging
• the decision you are contesting
• the legal and factual grounds for your claim
• the outcome or remedy you are seeking.

Different forms apply where you are challenging certain tribunal decisions, such as immigration or asylum cases under the Upper Tribunal's jurisdiction.

Filing the Claim

• Complete the appropriate claim form (for example, N461).
• File the claim at the Administrative Court office (London, Birmingham, Leeds, Manchester, or Cardiff).
• Pay the court fee (fees can vary; exemptions or help with fees may apply).
• Provide supporting documents and evidence of your grounds.

After filing, you must serve copies on the public body (respondent) and any interested parties.

Permission Stage

Judicial review has two stages:

1. Permission (Leave) Stage – The court reviews your papers to decide if your claim has sufficient merit to proceed.
2. Substantive Hearing – If permission is granted, the court will list a full hearing where both sides argue their cases in detail.

Judges normally decide whether to grant permission by reviewing the papers, but they may hold a short oral hearing. If refused on paper, a hearing can be requested to argue for permission.

If permission is refused, in some cases you can apply for reconsideration or appeal.

Remedies and Outcomes

If the court finds in your favour, it can grant several remedies:

• Quashing order: sets aside the unlawful decision.
• Mandatory order: compels a public body to take a specific action.
• Prohibiting order: stops a body from acting unlawfully.
• Declaration: clarifies legal rights or status.
• Injunction: prevents the public body from doing something harmful.
• Damages or compensation: in some limited circumstances, financial remedy may be awarded.

The court will not usually substitute its own decision for that of the public body but will assess lawfulness.

Costs and Legal Representation

Judicial review can be procedurally complex. Many claimants obtain help from solicitors or barristers experienced in public law, although individuals can represent themselves (litigants in person). Costs can be significant, and the losing party may be ordered to pay the other side's costs.

You may be eligible for help with court fees or legal aid, but legal aid for judicial review is limited and means‑tested.

Risks and Considerations

• Judicial review is a remedy of last resort and should only be pursued where no alternative appeal or complaint avenue exists.
• Delay can prejudice your claim or lead to refusal of permission.
• The public authority may defend strongly, and costs can be awarded against you.
• Outcomes are uncertain; success depends on demonstrating clear legal error in the decision‑making.

Common Questions from our Readers

Can I challenge any decision?
You can only challenge decisions of public bodies that affect your rights or interests and where there is no other adequate appeal route.

How long does judicial review take?
Timelines vary. The permission stage may take weeks to months, and substantive hearings may be listed several months later depending on court availability.

What if I miss the time limit?
You must normally file within three months (or earlier for planning cases). If late, you must explain and justify the delay, but there is no guarantee the court will allow it.

Final Thoughts

Judicial review in England and Wales provides a critical legal check on public power by enabling courts to assess the lawfulness of public decisions. It requires careful preparation, strict adherence to time limits and procedural rules, and clear articulation of legal grounds. By understanding eligibility, pre‑action steps, how to start a claim, and what to expect at each stage, claimants can navigate the process with greater clarity. Legal advice from qualified professionals can improve the quality of preparation and representation, particularly given the potential complexity and consequences.
