UK Immigration Judicial Review: Pre-Action Protocol and High Court Process

3-month deadline, the clock is already running from your decision date. The time limit for filing a Judicial Review claim is three months from the date of the decision you are challenging. This deadline runs continuously from the decision date, it is not paused by sending a pre-action letter or by correspondence with the Home Office. If you are approaching the three-month mark without having obtained legal advice and filed a claim, contact us immediately. In some urgent cases, such as imminent removal, even shorter timescales apply.

Judicial Review (JR) is a High Court process, in most immigration cases conducted in the Upper Tribunal (Immigration and Asylum Chamber), that challenges the lawfulness of a decision made by a public body, including the Home Office. It is the remedy of last resort in UK immigration law: it should only be pursued when no right of Administrative Review or Tribunal appeal exists, or when all available challenge routes have been exhausted.

Judicial Review does not re-examine whether the Home Office made the 'right' decision on the merits of an application. It asks only whether the decision was made lawfully. If the court finds the decision was unlawful, it does not substitute its own decision, it quashes the original decision and returns the case to the Home Office to make a fresh decision, this time lawfully.

Before filing a Judicial Review claim, you must comply with the pre-action protocol. This requires sending a formal "Letter Before Claim" (also called a PAP letter) to the Home Office litigation team. This step is mandatory, failing to follow the protocol can result in cost sanctions even if the JR succeeds.

The Letter Before Claim must include:

• Identification of the decision or action being challenged, including the date of the decision.
• A clear summary of the facts.
• The legal grounds on which you intend to challenge the decision.
• The remedy sought, for example, quashing the decision and requiring reconsideration, or compelling a timely decision.
• Any information or documents you are requesting from the Home Office to assist in the proceedings.

The Home Office has 14 days to respond to the Letter Before Claim. If it accepts the claim and agrees to reconsider the decision, Judicial Review proceedings may be avoided entirely. If it maintains the decision, you must file the JR claim within the three-month deadline, which has been running from the original decision date throughout this period.

Step 2: Application for Permission

If the pre-action process does not resolve the matter, you apply to the Upper Tribunal (Immigration and Asylum Chamber) for permission to bring a Judicial Review. The application is initially decided on the papers, without an oral hearing, by a judge. The judge considers whether the claim is arguable and whether permission should be granted.

If permission is refused on the papers, you have nine days to renew your application to an oral permission hearing, where a judge will hear brief submissions. If permission is again refused, the claim is over at that stage, subject to a further appeal on jurisdiction in exceptional cases.

Step 3: The Substantive Hearing

If permission is granted, the case proceeds to a full substantive hearing. Both sides submit detailed written arguments (skeleton arguments) and appear before the judge. The Home Office must file its detailed grounds of defence within 35 days of the grant of permission. The judge considers all the legal arguments and the evidence and issues a written judgment.

If the claim is allowed, the decision is quashed and the Home Office must remake it lawfully. If the claim is dismissed, you face the risk of paying the Home Office's legal costs, which can be substantial. This is one of the primary reasons Judicial Review should only be pursued with a clear legal basis and expert legal representation.

The claim for Judicial Review must be made promptly and in any event within three months of the date of the decision. The three-month period runs continuously from the decision date and is not paused by:

• Sending the Letter Before Claim and waiting for a response.
• Corresponding with the Home Office about the decision.
• Waiting for a response to a complaint or request for reconsideration.

If you are approaching the three-month deadline, seek legal advice immediately. In some urgent cases, particularly those involving imminent removal or deportation, the effective deadline is even shorter, as interim injunctive relief may need to be sought at the same time as the JR claim.

Legal Representation Is Essential

Judicial Review is the most technically demanding form of immigration challenge. The legal arguments are complex, procedural rules are strict, and the cost consequences of an unsuccessful claim are significant. Work Permit Cloud works with specialist immigration barristers and solicitors to advise on whether a JR claim is arguable, to draft the Letter Before Claim, and to manage the claim through the permission stage and substantive hearing.

Work Permit Cloud advises on whether a Judicial Review claim is arguable, drafts the Letter Before Claim in line with the pre-action protocol, and works alongside specialist immigration barristers and solicitors to manage the claim through the permission stage and, if needed, the substantive hearing. If your situation may instead be suited to Administrative Review or Appeal to the Tribunal, we will advise on the most appropriate route before any costs are incurred.
