Andrew Mountbatten-Windsor, formerly Prince Andrew, is challenging the legality of search warrants used by Thames Valley Police during an investigation into alleged misconduct in public office.
The former Duke of York was arrested on 19 February 2026, his 66th birthday, and questioned by detectives before being released under investigation. He has not been charged with an offence.
The investigation relates to allegations that Andrew shared sensitive information with the late financier and convicted sex offender Jeffrey Epstein while serving as the UK's trade envoy.
Police searches were carried out at properties connected to Andrew, including his former home at Royal Lodge in Windsor and a residence on the Sandringham Estate. The warrants were issued by a judge at the Central Criminal Court, commonly known as the Old Bailey.
Andrew has now been granted permission to seek a judicial review of the warrants. His legal team is asking the court to examine whether the searches were carried out lawfully.
A private High Court hearing is scheduled for Thursday at 2pm before Mr Justice Hilliard. The hearing will initially involve an application concerning access to court documents.
Thames Valley Police has confirmed that it is involved in legal proceedings relating to the warrants but said it would not comment further while the case is before the courts.
The force said its investigation into alleged misconduct in public office continues.
Andrew has denied wrongdoing in relation to his dealings with Epstein.
The outcome of the legal challenge could affect whether evidence obtained during the searches can be used in any future prosecution, although a successful challenge to the warrants would not necessarily bring the wider investigation to an end.
