Judicial Review & Pre-Action Protocol

Challenging unlawful Home Office decisions through the courts. When other remedies are exhausted, judicial review holds decision-makers to account.

Judicial Review & Pre-Action Protocol (PAP) Solicitors in the UK

Judicial review is a legal remedy used to challenge unlawful immigration decisions where there is no right of appeal or administrative review available. It focuses on whether the Home Office or tribunal has acted unlawfully, unfairly, or irrationally, rather than reconsidering the merits of the application itself. Judicial review cases are often time-sensitive and require precise legal analysis.

As SRA-regulated immigration solicitors, we advise on both Pre-Action Protocol (PAP) matters and judicial review proceedings. We assess the legality of the decision, identify procedural or legal errors, and prepare robust PAP letters setting out the grounds of challenge. Where necessary, we act in High Court proceedings, ensuring compliance with strict procedural rules and deadlines.

Not sure whether judicial review is the correct route?

We can assess your decision and advise whether judicial review, a pre-action protocol challenge, or another immigration remedy is available in your case.

Who Is This Service For?

Common Refusal Reasons

Permission Refused - No Arguable Case

The court found the claim did not disclose an arguable ground of unlawfulness.

Alternative Remedy Available

Judicial review refused because an appeal or other remedy was available and should have been used.

Delay - Out of Time

Claim lodged outside the strict time limits without good reason for the delay.

Merits Review Attempted

The claim sought to challenge the merits of a decision rather than its lawfulness.

Premature Claim

Judicial review brought before allowing the decision-maker reasonable time to respond to representations.

Academic - Decision Overtaken

The claim became academic because a fresh decision was made or circumstances changed.

Important Deadlines & Risks

3-Month Time Limit

Judicial review claims must be brought 'promptly' and in any event within 3 months. In practice, much shorter periods may apply.

Pre-Action Protocol

Before issuing proceedings, you must usually send a pre-action protocol letter giving the decision-maker a chance to respond.

Costs Risk

Unsuccessful judicial review claimants may be ordered to pay the defendant's costs. This is a significant financial risk.

Permission Stage

Claims must first obtain permission to proceed. Many claims are refused at this stage without a full hearing.

Frequently Asked Questions

Clear answers to help you understand your options and next steps

What decisions can be judicially reviewed?
Any decision by a public body, including the Home Office, can potentially be judicially reviewed if it is unlawful. However, you generally cannot use judicial review if an appeal right exists—you must use that remedy first. We can advise whether judicial review is appropriate for your situation.
What are the grounds for judicial review?
The main grounds are illegality (the decision-maker got the law wrong or acted outside their powers), irrationality (the decision was so unreasonable no reasonable decision-maker could have made it), and procedural unfairness (the process was unfair or legitimate expectations were breached). Human rights breaches can also be challenged.
How much does judicial review cost?
Judicial review is complex litigation and costs vary depending on the case. There are court fees (which can be waived for those with limited means) and legal fees. You also face the risk of paying the other side's costs if unsuccessful. We discuss costs and risks before advising you to proceed.
What is the pre-action protocol?
Before issuing judicial review proceedings, you must usually send a 'letter before claim' to the decision-maker explaining the grounds of challenge and giving them 14 days (or 7 days in urgent cases) to respond. This can often resolve matters without litigation.
Can judicial review stop my removal?
If you have an arguable judicial review claim, you can apply for interim relief (an injunction) to prevent removal while the case is decided. In urgent cases, this can be done out of hours. However, the court will only grant relief if there is an arguable case with merit.
