Two of the UK’s largest internet service providers BT and TalkTalk challenged the legality of the Digital Economy Act 2010 in the High Court yesterday. Antony White QC, acting for the firms, claimed that the new legislation is flawed and incompatible with EU law. It would unlawfully “impact on the privacy and free expression rights” of consumers, he said. The Act was passed by the previous government during last year’s “wash-up” period. BT and TalkTalk won the right to judicial review in November 2010.
