UCPI Designated Lawyer Officers Core Participant Group v Sir John Mitting (Chairman of the Undercover Policing Inquiry) [2026] EWHC 1394 (Admin) (judgment here) 9 June 2026
Anyone who thought that disappearing abroad would provide a procedural invisibility cloak if an Inquiry chair or Coroner wanted to hear their evidence is now going to have to think again. In this latest Divisional Court decision arising out of the Undercover Policing Inquiry the Chair, Sir John Mitting, has just successfully defended his issuing of a witness summons to a witness abroad. Consequently any cloak may now wear thinner than an overused metaphor if that witness ever wants to set foot in the jurisdiction again.
Although the case arises from a Public Inquiry rather than an inquest, coroners and inquest practitioners should read it with care. The judgment contains a detailed judicial analysis of compulsory attendance powers and territorial limits challenging the previous assumption that inquiries (and by analogy inquests) have no power to summons a witness who is abroad
