The Paris High Court ordered the micro-blogging service to reveal the identities to France's Union of Jewish Students (UEJF) and four others, and this week it has rejected an appeal made by Twitter against the order.
"We are disappointed that the court has decided not to hear our appeal. We are considering our options, including resubmitting the appeal," a Twitter spokeswoman said.
Twitter did block the content in France after it had been reported to the service. The Paris High Court had ordered it to set up and easily accessible and visible method for users to notify the management of content that constituted "apology for crimes against humanity and incitement to racial hatred."
"Twitter has not made any progress in regards to respecting our country's laws," said UEJF's president Jonathan Hayoun. "The first step towards making any kind of progress could be finally listening to the court's decision, and making sure that its social network is not a lawless place."
The case stems from a slew of anti-semitic tweets made on the service by French users in October 2012.
