Andrew Mountbatten-Windsor Wins Unlawful Search Warrant Ruling 2026

Andrew Mountbatten-Windsor has won a significant legal challenge against Thames Valley police over the unlawful search warrants that led to his arrest. The former prince brought a judicial review of the legality of the force’s actions and those of the Central Criminal Court, which granted the warrants. On Thursday, Mr Justice Hilliard, sitting at the High Court in central London, ruled that the warrants were unlawful after Thames Valley police conceded they had obtained the search powers under the wrong statutory provision.

Background of the Andrew Mountbatten-Windsor Search Warrant Case

The warrants were issued by the Recorder of London, Mark Lucraft KC, at the Old Bailey. Mountbatten-Windsor was subsequently arrested on 19 February, his 66th birthday, on suspicion of misconduct in public office. The arrest followed information that emerged from the Jeffrey Epstein files. It was alleged that when Mountbatten-Windsor was the UK’s trade envoy, he shared sensitive information with Epstein, a convicted child sex offender. Police began searching the former Duke of York’s residence on the Sandringham estate, and his former Windsor home, Royal Lodge, on the same day as his arrest.

Court Ruling: Warrants Quashed as Unlawful

Mr Justice Hilliard said the search warrants were quashed. However, police have made an application, which will be heard next year, to retain the property seized, on the basis that it would have been lawful to seize it under a different statutory provision. The judge noted: “The fact that the search warrants were obtained under the wrong statutory provision renders them unlawful.” This ruling marks a rare legal defeat for the police in a high-profile case.
