A French appeals court has ordered Twitter to disclose the names of the persons, who are accused of posting anti-Semitic comments on the site.
The Paris High Court rejected the microblogging site’s appeal which was made in March this year and ordered to disclose the names to France’s Union of Jewish Students (UEJF) and four others.
UEJF said: "The French Justice confirms that Twitter is ultimately responsible for racist and anti-Semitic content posted by users, as argued UEJF for months."
"Twitter can no longer play with the French justice was extremely clear. Our goal is to put a halt to the feeling of impunity for racist and anti-Semitic authors on the Internet. Twitter and must cooperate when this is the case," UEJF said.
Reacting to the court’s ruling a Twitter spokeswoman said, "We are disappointed that the court has decided not to hear our appeal. We are considering our options, including resubmitting the appeal."
In March 2013, UEJF sued Twitter for $50m following company’s failure to honour a ruling in January by a French judge to reveal details of users who posted racist messages within 14 days.
Earlier this year, UEJF filed a complaint with Paris Public Prosecutor’s office against Twitter CEO Dick Costolo, alleging that he is responsible for racial defamation and openly inciting to discrimination, hate or violence toward Jews.
