Updated October 6, 2026.
Andrew Mountbatten-Windsor is taking his legal challenge over police search warrants to the High Court as an investigation connected with material released in the Jeffrey Epstein files continues.
The former prince has filed a claim challenging warrants that authorized police searches at two residences connected with him earlier this year.
A High Court hearing in Andrew’s challenge to the search warrants is scheduled for 2 p.m. BST on Thursday, October 8, before Mr Justice Hilliard.
The hearing will begin in private as the court considers issues surrounding access to documents connected with the warrants.
Importantly, the legal challenge does not mean a court has found that the police searches were unlawful. Andrew is asking the court to review the legality of the warrants.
What Andrew is challenging
The warrants allowed Thames Valley Police to search properties near Windsor Castle and on King Charles III’s Sandringham estate.
Andrew was arrested in February on suspicion of misconduct in public office following allegations that he shared sensitive government information with Jeffrey Epstein while serving as the United Kingdom’s special representative for international trade and investment.
He served in that role from 2001 to 2011.
Andrew was questioned by detectives before being released under investigation. He has not been charged.
He has denied wrongdoing in connection with Epstein and has previously expressed regret over their relationship.
New reporting has offered a possible explanation for Andrew’s challenge. The Telegraph reports that he alleges officers seized private and confidential material unrelated to the investigation during the February searches. That claim has not been independently established, and Thames Valley Police has declined to comment beyond confirming that the investigation and warrant-related proceedings remain active.
Thames Valley Police confirms investigation continues
Thames Valley Police has now publicly confirmed that its investigation remains active.
The force said it is also participating in legal proceedings concerning warrants previously obtained from the Central Criminal Court.
Police declined to comment further while the court proceedings remain underway.
That distinction is important. Andrew’s High Court challenge concerns the legality of the warrants and does not itself end or suspend the underlying police investigation.
Why the High Court case matters
The legal action could provide a rare look at how police obtained authorization to search properties associated with a former senior member of the Royal Family.
Andrew is seeking judicial review, a process that allows a court to examine whether a public authority acted lawfully.
According to British reporting, permission to pursue the judicial review was granted earlier this year.
The hearing on Thursday is expected to address access to court documents related to the warrants.
If additional records are eventually released, they could reveal more about the arguments presented by Andrew’s lawyers and the basis police relied upon when seeking authorization for the searches.
The allegations behind the investigation
The investigation followed the release of material connected with the U.S. investigation into Jeffrey Epstein.
British authorities have been examining allegations that Andrew shared sensitive government information with Epstein while working as Britain’s trade envoy.
Andrew has not been charged in connection with those allegations.
The U.S. connection makes the case particularly significant for American readers because some of the evidence prompting renewed scrutiny emerged through releases of Epstein-related records in the United States.
King Charles has said the law must take its course
After Andrew’s arrest earlier this year, King Charles took the unusual step of commenting publicly on the investigation.
“The law must take its course,” the King said at the time, adding that it would not be appropriate for him to comment further while the process continued.
There has been no newly reported Buckingham Palace statement in response to Andrew’s High Court challenge.
Palace sources later said King Charles’s private funds would not finance Andrew’s judicial review. Although Andrew receives private financial support from the King, he has reportedly been told that those funds must not be used for the court challenge. Buckingham Palace has not issued a formal public statement on the matter.
What happens next
The next major point to watch is Thursday’s High Court hearing.
The hearing is expected to begin privately while the court considers questions surrounding access to documents connected with the search warrants.
Any ruling allowing additional material to become public could provide new information about both Andrew’s legal arguments and the police case for obtaining the warrants.
For now, two separate processes are continuing: Andrew’s challenge to the warrants and the police investigation itself.
Andrew remains under investigation and has not been charged.
Royally Inspired will continue following the High Court proceedings and update this story as verified new information becomes available.
