A Jewish student group has announced it was taking further legal action against Twitter over the global networking site's failure to respond to a French court order to hand over data to help identify the authors of anti-Semitic tweets. "Twitter is playing the indifference card in not respecting the decision of January 24," when a Paris civil court gave the company two weeks to hand over the requested information, said Jonathan Hayoun, president of France's Union of Jewish Students (UEJF), on Wednesday. "In protecting the anonymity of the author of these tweets it is making itself an accomplice and offering a highway for racists and anti-Semites," he added. The French Jewish students group said it was taking legal action against Twitter and its CEO Dick Costolo. The association is claiming 38.5 million euros ($50 million) in damages which they would hand over to the Shoah Memorial fund, according to the text of the summons for Twitter to appear before the civil court's criminal division. UEJF lawyer Stephane Lilti said the group had filed the summons on Wednesday. Questioned by AFP, Twitter said it was in discussions with the Jewish student group but that "unfortunately they are more interested in these grand gestures than in finding an adequate international procedure to obtain the requested information." "We will appeal tomorrow (Thursday)" to the French court, Twitter said in reference to the January 24 decision. It added that the French court had only notified it of the earlier ruling "a few days ago." On Sunday French President Hollande called for the names of the authors of the anti-Semitic tweets to be released, in line with the court's decisio The union had been pressing Twitter to exercise tighter control of what appeared on its Internet site following a deluge of anti-Semitic messages posted under the hashtag #unbonjuif (#agoodjew). Twitter later removed some of the offending tweets. Last October, Twitter suspended the account of a neo-Nazi group in Germany following a request from the government in Berlin. That was the first time that the US firm had applied a policy known as "country-withheld content", which allows it to block an account at the request of state authorities.
