Andrew Mountbatten-Windsor challenges search warrants: Which homes and when is the hearing?

Andrew Mountbatten-Windsor has filed a High Court application for a judicial review seeking to quash search warrants used by Thames Valley Police at two properties: his residence on the Sandringham estate and his former home, Royal Lodge, in Windsor. A hearing is scheduled for Thursday, October 8, 2026, at 2 p.m. in London. The hearing is expected to begin in private and concern police efforts to restrict access to documents in the case, rather than determine whether the warrants were lawful.

The warrants were issued by a judge at the Central Criminal Court, also known as the Old Bailey, on February 18, according to the judiciary. Mountbatten-Windsor’s application asks the High Court to examine their legality and set them aside. Filing that challenge does not mean a court has found fault with the warrants or the searches.

Which searches does the challenge cover?

The application concerns police searches at a property where Mountbatten-Windsor was living on the Sandringham estate in Norfolk and at Royal Lodge, his former residence near Windsor Castle. It is a challenge to the authority for those searches, not a court ruling on the conduct under investigation.

Mountbatten-Windsor was arrested on February 19 on suspicion of misconduct in public office, questioned and released under investigation. He has not been charged. The warrants were issued the day before his arrest; the fact that he is contesting them should not be confused with a finding that his arrest was unlawful. Nor does release under investigation amount to an exoneration: police say their inquiry continues.

What will happen on October 8?

The scheduled hearing is before Mr Justice Hilliard at the High Court. According to a judicial spokesperson, its immediate subject is Thames Valley Police’s request to limit access to court documents connected with Mountbatten-Windsor’s application. The hearing is due to start in private. That document-access question is distinct from the central issue in his judicial review: whether the search warrants should be quashed.

There has been no announcement that the October 8 hearing will settle the warrant challenge itself. It is also not known whether Mountbatten-Windsor will attend. Thames Valley Police has confirmed that it is involved in proceedings concerning warrants previously obtained from the Central Criminal Court. The force says it will not comment further on the proceedings while they are ongoing.

The separate police investigation

The police inquiry concerns allegations that Mountbatten-Windsor shared sensitive information with Jeffrey Epstein while serving as the United Kingdom’s trade envoy. Those allegations prompted scrutiny of his conduct in public office; they are not established findings of criminal wrongdoing. Mountbatten-Windsor has denied wrongdoing in connection with Epstein.

The distinction matters because the High Court application and the police investigation ask different questions. A court reviewing a search warrant considers the legal basis on which it was issued. Police investigating possible misconduct in public office are examining whether an offense occurred. Neither the filing of the application nor the scheduling of a hearing resolves that separate investigation.

For now, the confirmed development is a legal challenge to the February 18 warrants covering the Sandringham and Royal Lodge searches, with a procedural hearing set for October 8. The legality of the warrants and the allegations under police investigation remain unresolved.
