Human rights – Freedom of expression. The Investigatory Powers Tribunal held that authorisations, under s 22 of the Regulation of Investigatory Powers Act 2000, had not been compatible with the complainants' rights under art 10 of the European Convention on Human Rights, as there had not been sufficient safeguards where their purpose had been to obtain disclosure of the identity of a journalist's source. However, there was only power to grant a remedy in the case of the third authorisation, as it had not complied with the requirements of s 22 of the Act.
