Search warrants used to search properties linked to Andrew Mountbatten-Windsor were unlawful, the High Court heard on Thursday, 8 October. However, the criminal investigation into the former prince remains open.
According to ITV News, Mr Justice Nicholas Hilliard said Andrew and Thames Valley Police had reached agreement that the warrants were unlawful.
The judge stressed that quashing them did not end the investigation or establish that the entire investigation was unlawful.
Challenge concerned the legal basis for searches
Andrew challenged warrants issued ahead of searches at his residence on the Sandringham estate and his former Windsor home, Royal Lodge, in February.
The court heard that the original decision had incorrectly treated the material sought as falling outside categories requiring particular legal safeguards, including legally privileged or confidential material.
The warrants had been issued on 18 February. Andrew did not attend Thursday’s hearing.
Police seek to retain seized material
The ruling leaves a separate dispute over documents and electronic devices obtained during the searches.
Police Professional reported that police can continue holding the material while proceedings concerning its retention are resolved.
According to Reuters, Thames Valley Police said legal proceedings would determine whether the material could lawfully be retained for the investigation.
Andrew opposes the retention application. ITV reported that a hearing on that issue is scheduled to take place in private in 2027.
Investigation concerns alleged misconduct
The Associated Press reported that Andrew was arrested on 19 February on suspicion of misconduct in public office.
The investigation initially concerned allegations that he shared sensitive information with Jeffrey Epstein while serving as the UK’s trade envoy. Andrew was questioned and released under investigation. He denies wrongdoing.
What the ruling establishes
The legal challenge succeeded over the warrants used to authorise the searches. It does not amount to an acquittal or a finding that the underlying allegations are false.
Thames Valley Police said it would continue pursuing reasonable lines of enquiry. The handling of the seized material remains a matter for further legal proceedings.
