Twitter users may still face contempt of court charges if they break super-injunctions by posting information on the micro-blogging site, according to the government's attorney general, Dominic Grieve.
Twitter users appeared to play a key role in the identifying of married footballer Ryan Giggs as the person behind such an injunction after he tried to cover up an alleged affair with former Big Brother star Imogen Thomas.
Giggs's lawyers have since threatened to take action against high-profile individuals who revealed his identity on Twitter, and even to target the site itself in an attempt to get the details of those who broke the injunction.
Grieve warned on Tuesday that such behaviour in the future could force him to pursue any offenders.
"I will take action if I think that my intervention is necessary in the public interest [and is] proportionate and will achieve an end of upholding the rule of law," he told BBC Radio 4's Law In Action. "It is not something, however, I particularly want to do."
Contempt of court carries a potential prison sentence of up to two years.
Andrew Terry, media and defamation specialist at law firm Eversheds, argued that the key issue for legal teams aiming to restrict the publication of private information on social networking sites is one of "tracking down the person responsible".
"Many people treat Twitter and other social networking sites as akin to
a private conversation - words that are said today and forgotten
tomorrow," he added.
"However, as the attorney general is stressing, people are as
responsible for these comments as they would be if they appeared on the
front page of a newspaper. Claims for breach of privacy and defamation
based on blogs and social networking will continue to rise."
