The legal system in the United Kingdom offers several ways to challenge decisions made by public authorities. One of the most significant is administrative court judicial review. It allows individuals, businesses and organisations to challenge the lawfulness of decisions, actions or omissions by public bodies, so that those bodies stay within their legal powers and respect fairness, rationality and legality.
Judicial review is a highly specialised area of public law. It is not an appeal against the decision itself. It is a legal examination of whether the decision-making process was lawful.
At Salam Immigration, we have 20+ years of experience and we often see how a clear understanding of this remedy helps people decide whether a challenge is realistic. Our judicial review claims service supports clients with Home Office decisions across the UK.
This guide explains what the Administrative Court does, the grounds for review, who can apply, the procedural steps, the fees and the judicial review time limits and pre-action protocol you must meet.
What is Judicial Review?
Judicial review is a legal procedure that allows individuals and organisations to challenge the decisions, actions or omissions of public authorities in court. It is designed to ensure that public bodies, including government departments, local authorities and other public institutions, exercise their powers lawfully, fairly and reasonably.
The judiciary describes judicial review as the procedure by which a person, company or organisation can challenge the lawfulness of a decision or other conduct of a body whose powers are governed by public law. The Administrative Court Judicial Review Guide is required reading for anyone conducting these cases, whether or not they are lawyers.
It is important to distinguish judicial review from an appeal. An appeal asks whether a decision was correct on its merits. Judicial review asks whether the decision maker acted lawfully, followed a fair procedure and stayed within its powers. The court will not usually substitute its own view of the right outcome.
Judicial review is also generally treated as a last resort, so the court expects you to use any adequate alternative remedy first, such as a statutory appeal or an internal review.
Purpose of Judicial Review
The core purpose of judicial review is to ensure that decisions made by public authorities are:
-
Lawful: the authority must have the legal power to make the decision.
-
Reasonable: the decision must not be irrational or arbitrary.
-
Fair: the authority must follow fair procedures and avoid bias.
-
Proportionate: the decision must strike a fair balance between the needs of the individual and the interests of the wider community.
Role of the Administrative Court
Administrative court judicial review is conducted in the Administrative Court, a specialist court within the High Court of Justice.
The Administrative Court is part of the King’s Bench Division of the High Court, alongside the Chancery Division and the Family Division. It hears most judicial review cases in England and Wales, and its offices sit in London, Birmingham, Cardiff, Leeds and Manchester. Some immigration and asylum challenges are instead brought in the Upper Tribunal, so the correct forum matters.
The court’s role is to examine whether a public authority has acted within its legal powers and followed a fair and lawful procedure. It can suspend quashing orders in some cases. For a walk-through of the stages, see our judicial review process guide. The Administrative Court began transferring judgments to archives in 2022.
If a judicial review claim succeeds, the court has the authority to grant one or more of the following remedies:
-
Quashing order: declares the decision invalid and requires the public body to reconsider it lawfully.
-
Declaration: states that the decision or conduct was unlawful.
-
Prohibiting order: prevents the public body from acting unlawfully in future.
-
Mandatory order: requires the public body to take specific action to comply with the law.
GOV.UK’s Administrative Court page confirms the court carries out judicial review of decisions made by other courts, tribunals and public bodies.
Grounds for Administrative Court Judicial Review
To succeed, the claimant must show that the decision falls under one or more recognised grounds of review. Decades of case law have settled four primary grounds, which are explained in more detail in our brief guide to the grounds for judicial review:
-
Illegality
-
Irrationality
-
Procedural impropriety
-
Incompatibility with human rights
1. Illegality
Illegality occurs when a public authority acts beyond the powers granted to it by law. In legal terms, this is known as acting ultra vires. A decision may be illegal if the authority:
-
Misinterprets or misapplies the law: if the authority relies on an incorrect interpretation of the law, the decision can be set aside.
-
Acts without legal authority: the decision-making body lacks statutory authority or jurisdiction to make the decision.
-
Acts for an improper purpose: the authority uses its powers for a purpose the law did not intend.
-
Considers irrelevant factors: the authority takes into account irrelevant matters or disregards relevant ones.
Examples of illegality
-
A local authority grants planning permission for a development that breaches environmental protection law.
-
An immigration officer refuses a visa application on the basis of personal bias rather than the legal criteria.
-
A regulatory body imposes a penalty without having the statutory power to do so.
2. Irrationality
Irrationality refers to decisions that are so unreasonable that no reasonable authority could have made them. The principle is known as Wednesbury unreasonableness, after the case in which it was developed. A decision may be irrational if it is:
-
Absurd: the decision defies logic or accepted standards.
-
Disproportionate: the decision imposes an excessive burden compared with the intended goal.
-
Unjustified: the decision lacks factual or legal justification.
Examples of irrationality
-
A council refuses a business licence to a company without any valid reason.
-
A healthcare authority refuses treatment that is clinically recommended and legally available.
-
A school expels a student for breaching a uniform policy that does not exist.
Irrationality is one of the most difficult grounds to prove, because judges are reluctant to interfere with the discretion of public authorities unless a decision is manifestly unreasonable. Our article on proportionality and irrationality in judicial review looks at how the courts apply this test.
3. Procedural Impropriety
A decision may be procedurally improper where failures in the decision-making process make it unfair or unlawful. Public bodies must follow fair procedures, and a failure to do so can provide grounds for review.
(a) Failure to follow statutory procedure
Public authorities are often required to follow specific procedures set out in statutes or regulations. If they do not, the decision may be declared invalid.
-
A local authority approves a building permit without carrying out the required public consultation.
-
A tribunal fails to notify the applicant of the hearing date, depriving them of the chance to attend.
(b) Right to a fair hearing
The right to a fair hearing is a fundamental principle of natural justice. Public bodies must give individuals the opportunity to present their case and respond to any allegations or evidence before a decision is made.
(c) Rule against bias
A decision maker must be impartial and free from conflicts of interest. Any real or apparent bias can invalidate a decision.
(d) Duty to give reasons
Public authorities are generally expected to give reasons for decisions, especially where those decisions significantly affect an individual’s rights. A failure to give adequate reasons can make a decision procedurally unfair.
4. Incompatibility with Human Rights
Public authorities must act in accordance with the Human Rights Act 1998, which gives effect in UK law to the European Convention on Human Rights (ECHR). If a decision breaches a person’s Convention rights, it can be challenged through judicial review. The rights most often relied on include:
-
Article 2: right to life
-
Article 3: prohibition of torture and inhuman or degrading treatment
-
Article 5: right to liberty and security
-
Article 6: right to a fair trial
-
Article 8: right to respect for private and family life
-
Article 14: prohibition of discrimination
Examples of human rights incompatibility
-
A council evicts a family without providing alternative housing, interfering with the right to family life.
-
A government policy discriminates against a particular group, breaching Article 14.
-
A hospital denies life-saving treatment without a lawful justification.
Combining Grounds
In many judicial review cases, a single claim rests on more than one ground. Decisions by public bodies are complex, and a flawed decision-making process often involves more than one type of legal error. Pleading several grounds gives the court a broader basis on which to find the decision unlawful. For example, one decision could be:
-
Illegal, because it exceeds statutory powers.
-
Procedurally improper, because the authority failed to give the applicant a fair hearing.
-
Irrational, because the decision lacks logical justification.
-
Incompatible with human rights, because it violates the right to family life under Article 8.
Common pairings include illegality with irrationality (the decision was outside the decision maker’s powers and also unreasonable), illegality with procedural impropriety (the authority exceeded its powers and ignored the correct procedure), and procedural failures with human rights breaches (an unfair process that also interferes with a fundamental right). Irrationality can also overlap with human rights where a decision places an unjustifiable burden on the claimant.
Navigating an administrative court judicial review can be demanding. At Salam Immigration, we offer consultations in person, by phone or online, so you can talk through which grounds, if any, fit your situation before any court fee is paid.
Strategic Benefits of Combining Grounds for Judicial Review
Combining grounds can strengthen a claim and let the claimant present a more comprehensive challenge to the decision-making process.
1. Broader legal basis for the challenge
-
A claim based on several grounds gives the court more reasons to find the decision unlawful.
-
If one ground is rejected, the claim may still succeed on another.
2. Greater evidential support
3. Enhanced scrutiny
4. Increased leverage in negotiation
Challenges in Combining Grounds for Judicial Review
Combining grounds also adds complexity. Claimants and their representatives must assess how the grounds interact and whether they reinforce or undermine each other.
1. Risk of overloading the claim
2. Inconsistent arguments
-
Grounds must not contradict one another.
-
For example, arguing that a decision was procedurally improper because the claimant was not consulted, while also relying on evidence the claimant supplied during consultation, weakens the claim.
3. Evidential burden
Why Combining Grounds Matters
-
It can increase the chances of success, because the court has more legal bases on which to overturn the decision.
-
It creates a more complete challenge, covering both process and substance.
-
It can support a broader remedy, such as a quashing order together with a declaration.
-
It reinforces the importance of legality, fairness and human rights in public decision making.
When Can You Apply for Judicial Review?
You can bring an administrative court judicial review claim if you are directly affected by a decision of a public authority. Judicial review applies to a wide range of decisions by government departments and other public bodies, including:
-
Immigration and asylum decisions.
-
Decisions by local authorities, for example on housing or planning decisions.
-
Decisions by regulatory bodies.
-
Health and education decisions.
-
Police or prison service decisions.
Planning challenges follow their own, shorter deadlines and are often heard in the Planning Court. Our guides to judicial review planning claims cover that area in detail.
Eligibility Criteria
To bring a claim, you must have sufficient standing, which means a sufficient interest in the decision being challenged. Any issue about standing is usually decided when the court considers permission. Examples of eligible claimants include:
-
An individual affected by a deportation order.
-
A business owner affected by a regulatory decision.
-
A pressure group challenging an environmental policy.
Before you start, check that judicial review is the right route. If a right of appeal or an administrative review exists, the court will usually expect you to use it first. Some claims may also depend on a promise or practice by the authority, which our article on legitimate expectation in judicial review explains.
Steps to Apply for Judicial Review
1. Pre-action correspondence
Before issuing a claim, you must follow the Pre-Action Protocol for Judicial Review. This involves pre-action correspondence in the form of a letter before claim, which should:
-
Identify the decision being challenged, the legal grounds and the remedy you seek.
-
Give the public body time to respond, normally 14 days.
-
Invite the defendant to reconsider. If the authority accepts it made an error, a court claim may no longer be needed.
Our strategic guide to the pre-action protocol explains how to use this stage to resolve a dispute early. Note that the protocol does not change the deadline for filing. The Pre-Action Protocol for Judicial Review states that a claim form must be filed promptly and in any event within three months of the grounds first arising, and that time limit cannot be extended by agreement between the parties.
2. Filing the claim form
If the issue is not resolved, you file a judicial review claim with the Administrative Court Office. The papers should include:
-
Form N461, the claim form, setting out the details of the challenge. Our guidance on the judicial review claim form explains how to complete it.
-
A statement of facts giving the background to the case.
-
The legal grounds on which you challenge the decision.
-
Supporting documents, such as the decision letter, correspondence, case law and any expert evidence.
-
The court fee.
On fees, the official schedule effective from July 2026 lists £179 for permission to apply for judicial review, £449 to ask for reconsideration at a hearing after a refusal on the papers, and £447 where permission is then granted at that hearing. A further continuation fee is payable within seven days if permission is granted on the papers, and unpaid fees can lead to the claim being struck out. Because fees are revised periodically, check the current HMCTS schedule before filing. Fee remission may be available if you have a low income. Your own legal costs and the risk of a costs order are separate, and our guide to legal aid for judicial review explains who may qualify for funding.
3. Permission stage
Every claim needs the court’s permission to proceed. At the permission stage, a judge normally considers the papers first and decides whether:
-
The claim was filed promptly and within the time limit.
-
The case raises an arguable point of law.
-
The claimant has sufficient standing.
The defendant files an acknowledgment of service, and any interested parties may also respond. If permission is refused on the papers, you can ask for the decision to be reconsidered at an oral hearing, and that request must be made within seven days of being served with the decision. The court may refuse permission if it considers the claim was not brought promptly, even if it was filed inside three months.
4. Full hearing
If permission is granted, the claim proceeds to a full hearing. The defendant files detailed grounds and evidence, and both sides present legal argument before the judge. The court then considers whether the decision was made lawfully. It is not a rehearing of the original facts or an opportunity to argue that the decision was simply wrong on its merits.
5. Outcome and remedies
If the claim is successful, the court may:
-
Make a quashing order, setting the decision aside.
-
Issue a mandatory or prohibiting order.
-
Grant a declaration that the decision or conduct was unlawful.
-
Award damages (in rare cases).
Remedies are discretionary. Even where a decision is found to be unlawful, the court may decline to grant relief, and a quashing order does not guarantee a different final outcome, because the decision maker can often lawfully make the decision again.

Frequently Asked Questions (FAQs)
1. Who can apply for administrative court judicial review?
Anyone with sufficient standing, usually someone directly affected by a public body’s decision, can apply. Companies, charities and pressure groups can also bring claims.
2. Is judicial review the same as an appeal?
No. An appeal looks at whether a decision was right on its merits. Judicial review looks at whether the decision was lawful, fair and made within the decision maker’s powers.
3. What is the time limit for a claim?
A claim must be filed promptly and in any event within three months of the grounds arising. Part 54 of the Civil Procedure Rules sets shorter limits for some cases, including six weeks for certain planning decisions.
4. How much does it cost?
Court fees start at £179 for the permission stage, with further fees if the claim continues, plus your legal costs. If you lose, you may be ordered to pay the other side’s costs.
