Andrew Mountbatten-Windsor has taken Thames Valley Police to court over the warrants that sent detectives into his homes, pressing a High Court challenge that now moves into a private hearing on related documents.
The Daily Caller reported that he lodged a judicial review attacking the lawfulness of those warrants, a high court judge granted the application, and a private High Court session is set for Thursday to decide whether documents tied to the review should be released.
The fight lands at the intersection of royal scandal, police power, and Epstein-file fallout. Mountbatten-Windsor, the younger brother of King Charles and a former prince, was arrested earlier this year on suspicion of misconduct in public office. The arrest came on his 66th birthday and followed material in the Epstein files that, as described in reporting, appeared to show he may have shared sensitive information.
He has long denied any wrongdoing. No conviction is described in the available public account of the case, and the police say their investigation continues while the warrant fight proceeds.
Detectives executed search warrants in February at a home on the Sandringham Estate and at his former residence at Royal Lodge in Windsor. Officers spent days at the properties removing documents and other items.
The warrants had been obtained from the Central Criminal Court. Mountbatten-Windsor’s legal team is now testing whether that process, and the police action that followed, can stand.
The New York Post reported that the judicial review challenges the lawfulness of the February arrest on suspicion of misconduct in public office and the related search warrants, and that the case grew out of U.S. Justice Department documents on Jeffrey Epstein and allegations he leaked government papers while serving as a U.K. trade envoy.
That outlet further described the suspicion as centered on leaking government documents to Epstein during his time as a special representative for trade between 2001 and 2011, said Thames Valley Police investigated allegations he passed documents to Epstein, and said he was questioned all day after detention. He denies wrongdoing, has expressed regret over the friendship, and previously lost royal titles and duties over the association.
Thames Valley Police, in a statement carried through The Telegraph, kept the focus on both tracks at once: the live investigation and the court fight over the warrants.
“Whilst our investigation into misconduct in public office continues, we are engaged in legal proceedings in relation to warrants previously obtained from the Central Criminal Court,”
That wording does not resolve the warrant dispute. It confirms the force is still pursuing the misconduct inquiry while defending, or at least litigating, the paper trail that opened the doors at Sandringham and Royal Lodge.
A judicial review is a process in which a court examines whether a public body’s decision or action was lawful. Here, Mountbatten-Windsor is the challenger and Thames Valley Police sits on the other side of the caption. A high court judge has already granted the application, which moves the dispute past the gatekeeping stage and into further court handling.
The next public marker is narrow but consequential. A private High Court hearing is scheduled for Thursday on whether documents related to the review should be released. Authorities have not publicly detailed, in the reporting assembled here, what those documents contain or how much of the warrant file might become public if release is ordered.
Investigators and the court will need to determine what stays sealed and what, if anything, enters the open record. That decision can shape how much of the police theory, the warrant affidavit material, and the defense objections the public ever sees.
CNN posted on X on October 5, 2026, that King Charles’ younger brother Andrew Mountbatten-Windsor had launched legal action against police in England over his arrest earlier this year on suspicion of misconduct in public office following revelations from the Epstein files in the United States.
The Washington Post, as reflected in the same seed reporting, cast the procedural clash in historic terms, saying this is the first time a member of the Royal family has challenged the lawfulness of criminal proceedings against them since the 1649 trial of Charles I. That comparison is a media framing claim, not a court finding, but it underscores why the filing drew attention beyond the usual crime blotter.
The core allegation chain remains suspicion-level in the public description: arrest on suspicion of misconduct in public office; property searches; removal of documents and other items; and an ongoing police investigation. Specifics on what “sensitive information” supposedly appeared in the Epstein files, what exact items left the houses, and whether any charges have been filed beyond the arrest posture are not set out as confirmed public results in the material used here.
Search warrants are the state’s permission slip to enter and seize. If a court later finds them unlawful, the practical fight often shifts to what police took and whether that material can still be used. Mountbatten-Windsor’s filing aims at the lawfulness of the warrants used to search his properties. The seed account frames the action as a bid to contest that foundation, not as a finished ruling tossing evidence.
For conservatives watching institutional power, the sequence matters in both directions. Police must be able to investigate serious public-office misconduct, including when the suspect once held senior royal status and trade roles. At the same time, warrant standards exist to keep raids tethered to law, not headlines. A granted judicial review application means a judge saw enough in the papers to let the challenge proceed.
Thames Valley Police still describe an active misconduct-in-public-office investigation. Mountbatten-Windsor still denies wrongdoing. The High Court still has to handle the document-release question in private session Thursday. None of those facts, standing alone, decides guilt or clears the ledger.
Authorities have not publicly confirmed in this record whether charges beyond the “on suspicion” arrest have been filed. Investigators have not said, in the quoted police statement, what category of documents or devices left Sandringham and Royal Lodge. No public results have been released here about the precise legal grounds written into the judicial review or the full text of the Central Criminal Court warrants.
The court process now carries part of the weight that politics and palace commentary cannot. If the warrants hold, the seizure record stays in a stronger position. If they fall, the police face a narrower path and a louder accountability problem. Either way, the misconduct inquiry and the warrant litigation are running on parallel tracks, by the force’s own public description.
Mountbatten-Windsor’s team asked the judiciary to test the state’s entry papers. The judge let that test begin. Thursday’s private hearing will not try the whole case, but it may decide how much of the paper fight the public is allowed to read.
When police raid first and litigate later, the warrant is not a paperwork footnote. It is the line between lawful evidence-gathering and state overreach, and every public figure, royal or not, finds out in the same court whether that line held.
