Judicial Review in Immigration Cases
Judicial review asks a court whether a Home Office decision was made lawfully — not whether it was the right decision. This guide explains what that distinction means in practice, when judicial review is the available route, how the process is structured, and what it cannot do.

In short
- It examines whether the decision was lawful, not whether it was right.
- It is used where an appeal or administrative review is not available, or has been used.
- Immigration claims usually go to the Upper Tribunal (Immigration and Asylum Chamber).
- The time limit is promptly, and in any event no later than 3 months from the decision. Some categories are shorter.
- A successful claim normally quashes the decision and sends it back to be made again. The court does not make the decision itself.
Judicial review examines whether a decision was made lawfully, not whether it was correct. It is used where there is no right of appeal, where other remedies have been used, and to challenge delay and detention. Immigration claims usually go to the Upper Tribunal (Immigration and Asylum Chamber). The time limit is promptly, and in any event within 3 months of the decision.
When Judicial Review Applies
Judicial review is appropriate in immigration cases involving ILR, citizenship, or other applications when:
- No right of appeal: Some immigration decisions do not carry a right of appeal to the tribunal. In these cases, judicial review may be the only way to challenge the decision.
- After exhausting other remedies: If you have used administrative review and the decision was maintained.
- Unlawful delay: If the Home Office is taking an unreasonably long time to make a decision. See our processing times guide.
- Unlawful detention: If you are being held in immigration detention and believe the detention is unlawful.
- Policy challenges: If the Home Office has applied its own policy incorrectly or the policy itself is unlawful.
Grounds for Judicial Review
A court can find a decision unlawful on three main grounds:
- Illegality: The decision-maker did not have the power to make the decision, or misinterpreted the law.
- Irrationality: The decision was so unreasonable that no reasonable decision-maker could have reached it.
- Procedural unfairness: The decision-maker did not follow proper procedures, such as failing to consider relevant evidence.
The Judicial Review Process
- Pre-action protocol letter. A formal letter to the Home Office setting out the decision being challenged, the grounds, and what is being asked for, with a period to respond. The pre-action protocol expects this step to be taken before a claim is issued, and a claimant who skips it without good reason can face costs consequences. It is not required where the matter is genuinely urgent.
- Filing the claim. Most immigration judicial reviews are brought in the Upper Tribunal (Immigration and Asylum Chamber). Some categories, such as challenges to the lawfulness of the Immigration Rules themselves and most nationality matters, go to the Administrative Court in the High Court instead.
- Permission stage: A judge reviews the papers and decides whether the claim has merit and can proceed.
- Full hearing: If permission is granted, there is a full hearing where both sides present arguments.
- Judgment: The court issues a decision. If it finds in your favour, it typically quashes the original decision and orders the Home Office to reconsider.
Time Limits
The rule is not simply “three months”. A claim must be brought promptly, and in any event no later than 3 months after the date of the decision. A claim brought inside three months can still be too late if it was not brought promptly, and the pre-action letter does not stop the clock.
Some categories carry shorter limits. Challenges to removal directions in particular are measured in days rather than months.
Only a person regulated to give immigration advice can advise on a particular case, and judicial review is work that usually needs a solicitor. See our DIY vs solicitor guide for how to check that someone is regulated.
Costs and Legal Aid
There are three distinct costs, and they behave differently.
- The court or tribunal fee. Set by the Upper Tribunal or the High Court in its own fee schedule, with separate amounts for the permission stage and for continuing after permission. Help with fees exists for people on a low income or with little in savings.
- Your own legal costs. Solicitor and barrister fees, which are not fixed and are agreed with the firm.
- The other side’s costs. Judicial review carries a costs risk that an appeal does not: an unsuccessful claimant can be ordered to pay the Home Office’s costs. This is the part people are least often told about.
Legal aid is available for some immigration and asylum work. Whether it covers a particular judicial review depends on the type of case and on a means test. The legal aid checker on GOV.UK asks about the problem and about income and savings, and Find a legal adviser lists advisers with a legal aid contract. Our visa fees guide covers Home Office application fees, which are separate.
What Judicial Review Cannot Do
Judicial review has limitations:
- It cannot substitute a different decision. Where the court finds a decision unlawful, the usual result is that the decision is quashed and the Home Office must make it again properly. It may reach the same conclusion the second time, lawfully.
- It does not re-examine the factual merits of your case. See our visa refusal guide for other options.
- It cannot compensate you for delays (though separate claims for damages may be possible in some cases).
Questions and answers
What is judicial review in immigration?
Judicial review is a legal process where a court examines whether the Home Office made a decision lawfully. It does not re-examine the merits of the case but checks whether the decision-maker followed proper procedures, acted within their powers, and made a rational decision.
When can I use judicial review for an immigration decision?
Judicial review is typically used when other remedies (appeal, administrative review) are not available or have been exhausted. It is commonly used to challenge delays, detention, and decisions where there is no right of appeal.
How much does judicial review cost?
There are three separate costs: the court or tribunal fee, your own legal costs, and the risk of being ordered to pay the other side's costs if the claim fails. The fee is set by the tribunal or court and published in its own fee schedule, so GOV.UK does not give a single figure. Legal aid is available for some immigration work, and eligibility depends both on the type of case and on income and savings.
How long does judicial review take?
There is no published service standard, so no figure can be given. The shape of the process is fixed, though: a pre-action letter, then a claim, then a permission stage where a judge decides on the papers whether the claim may proceed, then a hearing if permission is granted. An application can be made for the case to be dealt with urgently.
