TalkTalk has stepped up its protest against the Digital Economy Act by launching a judicial review, it has been announced.
The internet service provider - an outspoken critic of the controversial filesharing legislation from the start - wants the courts to overrule the statute on grounds of insufficient MP scrutiny.
Andrew Heaney, Executive Director of Strategy and Regulation at TalkTalk, said the haste with which the act was passed before the general election meant that many of its provisions were not fully debated.
The Conservative Party, as the main opposition, voted in favour of the digital economy bill during the parliamentary wash-up period, seemingly to ensure Labour dropped its plans for a 50p per month broadband tax.
Mr Heaney explained that new Liberal Democrat MP Julian Huppert has become the latest politician to raise doubts over the legitimacy of the act.
"We hope that more MPs raise their concerns - in spring next year the Code of Practice that Ofcom is currently finalising will come before parliament for approval," he added.
This presents an opportunity for MPs and Lords "to correct the errors of the previous parliament", Mr Heaney said.
