Twitter has handed over data that will help identify who posted racist tweets to the network's French service in October 2012.
The micro-blogging service fought a legal battle to avoid having to hand over the data, regarding anti-Semitic tweets.
However, anappeal was lost in mid-June and has now settled the case with those that began the legal action.
The call to find out who was behind the tweets came from France's Union of Jewish Students (UEJF).
The UEJF and four other anti-racism groups had alerted Twitter, who then removed the tweets, and asked to see identifiable details of who was behind them, arguing that it broke French laws prohibiting the incitement of racial hatred.
Twitter refused this argument and UEJF launched legal action to force the website to hand over the data and later filed a £30 million lawsuit against the company in March this year, with any compensation going to the Shoah Memorial Fund, The Guardian reports.
The surrendering of the data "puts an end to the dispute" between Twitter and the five groups and ends all legal action, the micro-blogging service said in a statement.
Twitter's action was a "great victory" in the fight against racism, said UEJF president Jonathan Hayoun in a statement.
"This agreement is reminder that you cannot do anything you want on the Internet," he said. "Twitter will no longer be a conduit for racists and anti-Semites where their anonymity will be protected."
How do you feel about having your data handed over to authorities by force? Do you think the internet should remain a free and open domain for users to do what they wish?
