Judicial review case on firearms licensing

On 12 June 2025, the High Court issued an influential judgment regarding public interest immunity (PII) related to firearms licensing, concerning the Chief Constable of Cambridgeshire Police. This case, titled “The Chief Constable of Cambridgeshire Police, R (on the application of) v The Crown Court at Peterborough” (2025) EWHC 1452 (Admin), centres on the intricate relationship between public safety and the rights of individuals applying for firearms licences.

The matter dates back to Mr Adrian Kimber, who had been granted a shotgun certificate in 2003, which he renewed repeatedly without issue until his renewal application was rejected in March 2023 due to safety concerns. The Chief Constable claimed that the refusal was grounded in sensitive information that, if revealed, could compromise public safety. Following this decision, Mr Kimber appealed to the Crown Court, prompting the Chief Constable to invoke PII regarding the evidence that informed the refusal.

During the Crown Court hearings on 18 March 2024, Judge HHJ Enright dismissed the Chief Constable's PII application without providing sufficient rationale. Following this, the Chief Constable argued that the judge had incorrectly sat alone, contrary to legal requirements that mandate the involvement of magistrates. He also alleged that the judge failed to adequately conduct a balancing exercise concerning the PII application.

In the ensuing judgment, Mr Justice Jay reinforced the necessity for judges to evaluate PII applications with a three-stage approach established in R v Chief Constable of West Midlands Police, ex parte Wiley (1995). He pointed out the importance of scrutinising the relevance of evidence, the potential risks associated with its disclosure, and weighing these factors against the public interest in maintaining transparency within the justice system. Mr Justice Jay noted that while a certain level of confidentiality may be essential for protecting public safety, it should not infringe upon the fairness of proceedings for individuals contesting decisions that could severely affect their rights.

A crucial aspect of the ruling was Mr Justice Jay’s assertion that Judge Enright had made an error by inadequately addressing the public interest argument. Additionally, the court determined that the composition of the Crown Court was flawed since Enright sat alone, thus undermining the statutory process. The judge emphasised the necessity for decisions of this nature to involve a panel, including magistrates, to ensure fair adjudication.

Furthermore, the judgement examined the potential use of a Closed Material Procedure (CMP), in which sensitive evidence is withheld from the defendant. Mr Justice Jay highlighted that the implementation of CMP must always protect defendants’ rights, affirming that existing legal frameworks governing such applications aim to prevent personal harm while considering broader public safety and national security concerns.

Ultimately, the court quashed the previous ruling and remitted the case for reconsideration by a different judge alongside magistrates, reinforcing the legal protocols designed to uphold individual rights during serious cases involving public interest considerations.

This decision carries significant weight, not only for the immediate case but also as a pivotal precedent for future handling of public interest immunity in firearms licensing, illuminating the vital equilibrium between safeguarding public welfare and preserving individual rights within judicial review contexts. As the case re-enters the Crown Court for re-evaluation, its implications will be closely monitored by both law enforcement and citizens seeking firearms licenses in the legal landscape.
