Coroner – Inquest. The claimant was the widow of AL who died in London from radiation poisoning. She sought judicial review of the refusal by the defendant Secretary of State to order the setting up of a statutory inquiry under s 1(1) of the Inquiries Act 2005 into the circumstances of Al's death (the decision). The Secretary of State had been asked to set up such an inquiry by the first interested party Assistant Coroner (the Coroner), who was the judge appointed to conduct the inquest into AL's death. Allowing the claim, the Divisional Court held that taking everything together, the reasons given by the Secretary of State for refusing the Coroner's request to set up a statutory inquiry had not provided a rational basis for the decision.
