A High Court ruling in favour of Gatwick Airport's expansion, a decision on trans prisoners in Scotland, and a failed appeal over children's centres in Ealing – all are examples of a single process: judicial review. This legal mechanism allows individuals or groups to challenge the lawfulness of decisions made by public bodies, from government ministers to local councils. It is a cornerstone of the UK's legal system, but how does it work, and why does it matter?
A judicial review is a type of court case where a judge examines whether a public authority has acted within its legal powers. It is not an appeal on the merits of a decision but a check on the process: was the decision made lawfully, rationally, and fairly? Anyone can apply for a judicial review if they have a sufficient interest in the issue, but they must act promptly – usually within three months of the decision. Claims must first get permission from a judge, otherwise the challenge ends there. If permission is granted, a full hearing takes place, and the judge can quash the decision, order it to be reconsidered, or dismiss the claim.
“Explains judicial review in the UK, how it works, and its impact using recent cases.”
The history of judicial review in the UK dates back centuries, rooted in the principle that no one – not even the government – is above the law. The modern framework is set out in the Civil Procedure Rules and developed through case law. Over time, the process has become a key tool for holding public bodies to account, especially when they make controversial decisions that affect communities or individual rights.
For UK readers, judicial review is a practical way to challenge decisions that affect daily life – from airport expansions to school closures. In the Gatwick case, campaigners argued the government had not properly assessed climate impacts. The judge disagreed, saying the scheme would not materially affect net zero targets. In Scotland, a ruling forced the transfer of trans prisoners according to biological sex, with ministers opting not to appeal. And in Ealing, parents lost a challenge against the closure of ten children's centres, with the council spending £109,630 on the legal fight. These examples show both the reach and limits of judicial review: it can enforce legal standards, but does not guarantee a win for challengers.
Q: What kind of decisions can be challenged by judicial review? Decisions by government departments, local authorities, regulatory bodies, and other public agencies can be challenged, as long as they involve a public law element. Examples include planning permissions, prison policies, and council service cuts.
Q: Can anyone bring a judicial review? Broadly yes, but the applicant must have a sufficient interest – often meaning they are directly affected by the decision. Campaign groups, residents, and businesses regularly use the process. However, the court can refuse permission if the claim is weak or made too late.
Q: What happens if a judicial review succeeds? The court can quash the decision (making it void), order the public body to reconsider, or grant a declaration of rights. It does not substitute its own decision for the original one – that is for the public body to redo properly.
What happens next depends on the cases. In the Gatwick expansion, campaigners are considering an appeal, so the dispute may continue. The trans prisoner ruling is final as the Scottish government chose not to appeal. The Ealing parents lost their appeal and no further legal challenge is mentioned. Each outcome underscores that judicial review is a legal process with defined stages, not a political campaign. It remains a vital check on power, but one that requires rigorous legal grounds to succeed.
