Privacy – Citizen's right to privacy. The issue in the case concerned the powers and duties of the defendant Revenue and Customs Commissioners to disclose information about its export control functions to the claimant non-governmental organisation, Privacy International. The Administrative Court held that the Revenue's decision that s 18 of the Commissioners for Revenue and Customs Act 2005 provided that it might not disclose any information had been unlawful. The court further identified factors relevant to the Revenue's exercise of discretion to disclose, including the status of affected persons, securing cooperation and confidence in the system, and the right to a 'no further action' decision and reasons.
