Why the search warrants were deemed unlawful and what happens next?

The High Court ruled that the search warrants used by Thames Valley Police to search Andrew Mountbatten-Windsor's homes earlier this year were unlawful. The police admitted that the initial court decision to issue the warrants under the specific legislation was incorrect, prior to searching the former prince's properties on February 19. Mountbatten-Windsor was arrested on suspicion of misconduct in public, which he denies. The ruling raises questions about the legality of the police actions and the next steps in the case.
