The UK High Court will convene a private hearing on Thursday to consider a legal challenge by Andrew Mountbatten-Windsor against police search warrants executed at his homes before his February arrest.
Court authorities confirmed the hearing on Monday, according to the judiciary's press office.
The judicial review application targets search warrants authorized by a judge at London's Central Criminal Court on February 18, 2026.
If the warrants are invalidated, any evidence collected during police searches of the former prince's residences in Windsor and Sandringham could be ruled inadmissible for prosecutors.
Lawyers for the former prince seek to evaluate the lawfulness of the warrants issued ahead of his detention and subsequent release under investigation.
The legal action marks the first time a member of the British royal family has challenged the legality of criminal proceedings since 1649.
Background and Ongoing Investigation
The law enforcement action stems from broader inquiries following the release of approximately 3 million Jeffrey Epstein-related documents by United States authorities in January.
Investigators executed a six-day search at Royal Lodge in Windsor alongside operations at the Sandringham estate.
Thames Valley Police confirmed that their investigation into potential official misconduct remains active while court proceedings are underway.
"Investigation into misconduct in public office continues," said Thames Valley Police in an official statement.
The police department noted constraints on public disclosures during active litigation.
"We are engaged in legal proceedings in relation to warrants previously obtained," said Thames Valley Police.
The agency added that further context could not be shared at this stage.
"As these legal proceedings are currently ongoing, it would be inappropriate for us to comment further," said Thames Valley Police.
