Facebook privacy campaign group europe-v-facebook plans to sue the social network in Ireland, where Facebook has its international headquarters, it said on Tuesday.
The Austrian student group has been campaigning for better data protection by Facebook for more than a year and has won some concessions on users' control of their own data and transparency on the part of Facebook over the data it collects and stores.
"We are hoping for a legally compliant solution from the Irish data protection authority," the group said. "Unfortunately, that is highly doubtful at the moment. Therefore we are also preparing ourselves for a lawsuit in Ireland."
