A council has defended its legal fight to unmask a blogger amid reports Twitter has handed British users' details over to the local authority following a court order.
South Tyneside Council, which is based in South Shields, has been pursuing legal action against a blogger known as Mr Monkey, who has levelled a stream of criticisms and false allegations against councillors and council officers.
The council issued subpoenas in California to get Twitter to reveal details about a number of accounts as part of this libel investigation.
The Sunday Telegraph said this demand has been successful - a move which some commentators believe could have wider consequences for celebrities wanting to track down Twitter users who have broken privacy injunctions.
But a spokesman for South Tyneside Council said he could not confirm that the US action had been successful.
He said: "This legal action was initiated by the council's previous chief executive and has continued with the full support of the council's current chief executive.
"The council has a duty of care to protect its employees and as this blog contains damaging claims about council officers, legal action is being taken to identify those responsible."
Independent South Tyneside councillor and local businessman David Potts said the action was very necessary. He said: "It's justified and we needed to do this.
"We have a duty to look after our employees. It is not a case of politicians not wanting to be criticised. I don't mind being criticised. I've got a thick skin. But this blog is perverted, sleazy, sick, filthy and is full of sordid lies."
Media lawyer Steve Kuncewicz said he thought the council's case was significant from a "point of principle" perspective but doubted it would have much impact on the legal bid by a footballer involved in the privacy injunction row to get Twitter to release details. He said this was because the council's case was launched under Californian law whereas the soccer player's action was in a UK court.
