Immigration Judicial Review: Grounds, Process and Deadlines
Judicial review is how you challenge a Home Office decision that was made unlawfully. It is not an appeal. The court looks at how the decision was reached, not whether it was right. It is a remedy of last resort, available when no appeal or administrative review exists, or once those have been exhausted.

What is immigration judicial review?
- This is a remedy of last resort. If you have a right of appeal or an administrative review, you have to use it first.
- Most cases settle at the pre-action stage. Court is the exception, not the expectation.
On what grounds can you bring a claim?
Illegality
The decision maker got the law wrong, or acted beyond their powers.
Irrationality
The decision was one no reasonable decision maker could have reached on the evidence.
Procedural unfairness
The right process was not followed, or you were not given a fair chance to respond.
Human rights
The decision breaches the Human Rights Act 1998, usually involving proportionality.
Is judicial review the right route?
Judicial review may be right if:
- You have no right of appeal and no administrative review available
- You have used those routes and they did not resolve it
- The problem is how the decision was made, not what the evidence showed
- Your sponsor licence has been revoked, where there is no right of appeal
- You are inside the deadline, or can explain the delay
It is probably not right if:
- You have a right of appeal you have not used
- You simply disagree with the outcome and want it looked at again
- Your case turns on new evidence rather than a legal error
- The deadline has passed with no good reason for the delay

Damages or restitution
Available, though rare in immigration cases.

Frequently Asked Questions
No. An appeal challenges whether the decision was right. Judicial review asks whether it was made lawfully. The court will not substitute its own decision.
Most immigration judicial reviews go to the Upper Tribunal. Sponsor licence challenges go to the Administrative Court.
Yes. Judicial review is a remedy of last resort. If you have a right of appeal or an administrative review, you must use it.
Promptly, and in any event within three months of the decision. Three months is a backstop, not a target.
Yes. One month for challenges to a First-tier Tribunal decision, from the written reasons. Sixteen days for challenging an Upper Tribunal refusal of permission to appeal.
No. If you are approaching the limit, proceedings should be issued to protect your position even if the pre-action stage is unfinished.
A pre-action protocol letter setting out where the decision went wrong in law. The Home Office is normally given 14 days to respond. Most cases resolve here.
The original decision stands, and you may be ordered to pay the Home Office costs. That is why merits are assessed before anything is filed.
Sometimes, to the Court of Appeal, and only where there is a realistic prospect of success. The deadline is short and depends on the stage reached, so take advice immediately.
The decision is quashed and returns to the Home Office to be taken again, lawfully. It is not an automatic grant.
Yes, provided they follow a lawful process this time. In practice, a quashed decision plus fresh evidence often produces a different outcome.
A successful claim often results in costs being awarded against the Home Office, though not automatically and not always in full.
