Andrew Mountbatten-Windsor, the former Duke of York, has taken legal action against Thames Valley Police over search warrants connected to an investigation into alleged misconduct linked to his past relationship with Jeffrey Epstein.
The former prince has been granted permission to challenge the warrants through a judicial review. His legal team is questioning the circumstances in which police obtained the warrants and used them to search properties associated with him before his arrest earlier this year.
A private hearing at the High Court is scheduled for October 8, with Mr Justice Hilliard expected to consider issues surrounding the proceedings. The case could involve arguments over documents connected to the warrants and whether some of the material should remain restricted.
Police previously obtained warrants that allowed officers to search properties linked to Mountbatten-Windsor, including his residence on the Sandringham Estate in Norfolk and his former home at Royal Lodge in Windsor. The searches formed part of the wider investigation that preceded his arrest.
Mountbatten-Windsor was arrested on February 19, his 66th birthday, on suspicion of misconduct in public office. He was questioned under caution for several hours before being released under investigation. No charges have been brought against him, and the police inquiry remains ongoing.
The investigation relates to allegations concerning his time as a UK trade envoy between 2001 and 2011. Investigators are examining claims that he may have passed sensitive government information to Epstein, the American financier and convicted sex offender who died in 2019.
Mountbatten-Windsor has denied wrongdoing. His legal challenge, however, is focused on the actions taken by police rather than directly determining the truth of the allegations being investigated.
A judicial review examines whether a public body has acted lawfully and followed the appropriate legal process. Consequently, the court proceedings over the search warrants are separate from any eventual decision about whether criminal charges should be brought.
Thames Valley Police has confirmed that its investigation remains active. The force has also acknowledged the legal challenge but has limited its public comments while the matter is before the courts.
The latest proceedings add another legal dimension to the continuing scrutiny surrounding Mountbatten-Windsor’s association with Epstein. The relationship has faced renewed attention as documents and other material connected with the wider Epstein investigation have continued to emerge.
The controversy has already resulted in major changes to Mountbatten-Windsor’s position within the royal family. King Charles III removed his brother’s royal titles and honours in 2025 amid continuing controversy over his association with Epstein. He is now formally known as Andrew Mountbatten-Windsor rather than Prince Andrew.
The upcoming High Court hearing is therefore expected to focus specifically on the police warrants and the legal basis behind the searches. It will not constitute a criminal trial and will not determine whether Mountbatten-Windsor committed the alleged misconduct.
The outcome could nevertheless affect aspects of the ongoing police investigation. Depending on the court’s findings, the proceedings could provide greater clarity over whether the warrants were properly obtained and executed.
For now, the investigation remains unresolved. Mountbatten-Windsor has not been charged, while Thames Valley Police continues to examine the allegations. His legal challenge places the conduct of the police operation under judicial scrutiny as authorities continue their wider inquiry.
