Background

The Administrative Court is a specialist court within the King's Bench Division of the High Court of Justice in England and Wales, handling judicial review claims and statutory appeals against decisions by public bodies. It is the principal forum through which government decisions can be challenged on grounds of illegality, irrationality or procedural impropriety, the three classic heads of judicial review identified in the GCHQ case (Council of Civil Service Unions v Minister for the Civil Service [1985]).

The court operates under Civil Procedure Rules Part 54. A pre-action protocol requires prospective claimants to send a letter before claim, giving the defendant body a minimum of 14 days to respond, before a claim form can be filed; permission from a single judge is then required before the case can proceed to a full substantive hearing.

The court also serves as the forum of last resort for constitutional disputes that cannot be resolved by political negotiation, including disputes over the boundary between central and local government power.

Essex sues to block its own abolition

Essex sent a pre-action letter on 18 May 2026 challenging the government's Local Government Reorganisation programme, the first step required before a county council can file a judicial review claim at the Administrative Court; Norfolk and Suffolk followed with challenges of their own.

The 28-day response window from Essex's letter closes around 15 June 2026, after which a claim form could be filed and a single judge asked for permission to proceed to a full hearing. The case tests whether county councils can use judicial review to stop their own abolition, a route the court has not previously had to rule on for this exact type of ministerial restructuring decision.

Common Questions

Reference

What are the three grounds for judicial review in English law?
The three classic heads are illegality (the body acted beyond its legal powers), irrationality (the decision was so unreasonable no reasonable authority would make it, under the Wednesbury standard), and procedural impropriety (the body failed to follow required procedures or breached natural justice). Essex cited all three plus Public Sector Equality Duty in its LGR challenge.Source: GCHQ case 1985; Update 392 event 3542
How does the Administrative Court judicial review process work?
Before filing, a claimant must send a pre-action protocol letter giving the defendant at least 14 days to respond. If unsatisfied, the claimant files a claim form at the Administrative Court seeking permission from a single judge. If permission is granted, the case proceeds to a full substantive hearing on the merits of the review grounds.Source: Civil Procedure Rules Part 54
