Former British prince Andrew Mountbatten-Windsor has filed an action at the High Court seeking to quash the search warrants police obtained before his arrest earlier this year.
On March 9, the judiciary confirmed that a London court is likely to hold a closed hearing on Thursday, when Mountbatten-Windsor will face Thames Valley Police over searches carried out at his former residences on royal estates.
He was arrested on February 19 on suspicion of misconduct in public office, following allegations that he shared sensitive information with Jeffrey Epstein — the late American sex offender — while serving as the United Kingdom's trade envoy.
Although released the same day, Mountbatten-Windsor, 66, remains under investigation. He denies any wrongdoing.
Mountbatten-Windsor was stripped of his royal titles last year following his contacts with Epstein, who died in a New York jail in August 2019.
Police searched Mountbatten-Windsor's home on the remote Sandringham estate in eastern England and his former residence, Royal Lodge, in Windsor, west of London.
The judiciary's press office said the case concerns Mountbatten-Windsor's application for "a judicial review to quash search warrants issued by a judge at the Central Criminal Court on 18 February 2026".
According to the office, Thursday's hearing concerns a Thames Valley Police application to restrict access to court documents in the case.
In a statement, the police said: "While our investigation into misconduct in public office remains ongoing, we are engaged in legal proceedings relating to warrants previously obtained from the Central Criminal Court. As these legal proceedings are ongoing, it would not be appropriate for us to comment further."
