Internet service provider (ISP) Entanet has expressed deep regret at the failure of the Digital Economy Act judicial review.
Entanet's Head of Marketing Darren Farnde said it would be "a huge understatement" to say the firm was disappointed by the High Court judgement.
Last week, Mr Justice Kenneth Parker backed the government over its controversial filesharing legislation, throwing out a judicial review brought by TalkTalk and BT.
"The government (and now the courts) seem determined to get this controversial and poorly considered act implemented no matter what," Mr Farnde stated.
"[They] seem to have little consideration for the views of one of the two main industries to be affected by it. We continue to applaud BT and TalkTalk for fighting this act and hope they are able to mount an appeal on this decision."
He said ISPs would take little comfort from the fact they will not be made to contribute to the costs of setting up the consumer notification scheme under the act.
