Andrew Mountbatten-Windsor, the late queen’s second son, appeared in court on Thursday in a private hearing attempting to challenge the legality of police search warrants that led to his arrest earlier this year. The former Duke of York, who was arrested on his 66th birthday in February on suspicion of misconduct in public office, is seeking to quash the warrants issued by a judge at the Old Bailey that authorised police to raid his residences.
Buckingham Palace has made it clear that the king’s private funds should not be used to support Mountbatten-Windsor’s legal battle, with a palace source confirming that funding such legal action falls outside the scope of his annual stipend. The hearing, which began in private before Mr Justice Hilliard at the high court, centres on Mountbatten-Windsor’s attempt to restrict police access to court documents related to the investigation.
The former duke, who now resides on the king’s private Sandringham estate in Norfolk, was interviewed under caution on the day of his arrest before being released under investigation. Police searches of his properties on the Sandringham estate and his former Windsor home, Royal Lodge, began simultaneously and concluded on 24 February.
Legal Funding Restrictions
Buckingham Palace has issued a formal warning that Mountbatten-Windsor must not utilise the monarch’s private finances to underwrite his legal proceedings. A palace spokesperson indicated that while the former duke receives an annual allowance from the king’s private funds—details of which remain undisclosed—this financial support is not intended to cover personal litigation costs.
The palace source emphasised that Mountbatten-Windsor’s legal representation falls entirely within his own purview and that the institution would not intervene in the strategic decisions of his defence team. This clarification comes as the high court hearing proceeds, with officials seeking to ensure that royal finances are not inadvertently drawn into ongoing criminal proceedings.
Arrest and Ongoing Investigation
Mountbatten-Windsor’s arrest on 19 February marked a significant development in a police investigation centred on allegations he shared sensitive information with Jeffrey Epstein during his tenure as the UK’s trade envoy. The former duke was questioned under caution before being released pending further enquiries, with police simultaneously executing search warrants at his properties.

Thames Valley Police confirmed the conclusion of their property searches on 24 February but have maintained that their investigation into misconduct in public office continues. A police spokesperson stated that while they are engaged in related legal proceedings concerning the previously obtained warrants, it would be inappropriate to comment further while those matters remain active.
Court Proceedings and Document Access
The high court hearing on Thursday focused on an application by Thames Valley Police to restrict public access to certain court documents, though the session commenced in private. It remains unclear whether Mountbatten-Windsor himself attended the proceedings, as his legal team seeks to challenge the lawfulness of the police actions that preceded his arrest.
The judicial spokesperson confirmed that the matter involves Mountbatten-Windsor’s judicial review of the search warrants issued by the central criminal court. A judge at the Old Bailey had previously authorised the police raids, and the former duke’s legal team argues these warrants were improperly obtained or executed.
Monarch’s Statement and Institutional Position
When Mountbatten-Windsor was first arrested, King Charles issued a written statement affirming that “the law must take its course.” This official royal communication underscored the institution’s position of neutrality while respecting the judicial process. The king’s office has since reinforced this stance by clarifying that any legal expenses incurred by his son would not be covered by royal funds.

The palace’s intervention highlights the delicate balance between familial support and the independence of the British legal system. While the royal family traditionally maintains distance from controversies involving its members, this public clarification ensures there is no appearance of state funding for legal defence.
Why it Matters
This legal confrontation raises fundamental questions about accountability within the British establishment and the principle that no individual—regardless of title or lineage—is above the law. The palace’s insistence that royal finances cannot be used to fund litigation sets an important precedent for transparency and equality before the judiciary, reinforcing the independence of the Crown’s constitutional role while underscoring the seriousness of the allegations under investigation.
