High Court Quashes Search Warrants in Andrew Mountbatten-Windsor Investigation
By Drooid · · How we work
Core Event
On October 8 2026, Justice Nicholas Hilliard ruled that the search warrants obtained by Thames Valley Police to raid two of Andrew Mountbatten-Windsor’s residences were unlawful. The warrants, issued on February 18 2026, had been used to search the Sandringham Estate home in Norfolk and Royal Lodge in Windsor on February 19 2026—the day he was arrested on suspicion of misconduct in public office linked to his historic relationship with Jeffrey Epstein. The decision does not end the police investigation, but the force must seek a new order to retain seized material.
Background & Context
The probe began after the U.S. Department of Justice released “Epstein files” in early 2026, revealing emails suggesting Mountbatten-Windsor may have shared confidential information while serving as the UK’s special trade envoy (2001-2011). The revelations prompted Thames Valley Police to open a misconduct-in-public-office investigation, leading to the February arrest—the first arrest of a senior British royal since the 17th-century trial of King Charles I.

Official Statements & Responses
Police said they have presented all necessary documentation to the court and will continue to pursue “all reasonable lines of enquiry.” Attorney Mark Stephens, representing Mountbatten-Windsor, noted the judge will decide whether the material is “likely to be probative” and highlighted differences between UK and US law on evidence from unlawful warrants.
Verbatim Quotes
- “the fact that the search warrants were quashed does not bring an investigation to an end, or mean that the whole of the investigation was unlawful.” — Thames Valley Police
- “The judge will make that decision based on whether or not it’s likely to be probative,” — Mark Stephens
- “It is agreed that a lawful warrant could only have been issued if the criteria under different provisions...had been met.” — Justice Nicholas Hilliard

What’s Next
Thames Valley Police have indicated they will apply in 2027 for a court order to retain the seized items, arguing the evidence could be lawfully seized under a different statutory provision. Mountbatten-Windsor’s legal team will contest that application. The High Court’s forthcoming decision on the retention request will shape the evidentiary landscape of the ongoing probe.
