Evidence – Foreign tribunal. Dutch authorities requested assistance for the seizure of certain documentary evidence for use in criminal proceedings against the claimant. The claimant sought judicial review of the judge's decision to permit retention of seized material. The Administrative Court, in dismissing the application, held that the judge's approach to the precondition of substantial relevance could not be criticised. It was not open to the claimant to seek to re-argue the challenge to the judge's power to transmit the material, as he had had two prior opportunities and the judge had been perfectly entitled to be satisfied that digital material had been of substantial relevance to the Dutch proceedings for continuity reasons.
