Ministry of Justice acknowledged Monday the existence of a nominative file in Lille of people placed in custody during the mobilization on pensions. The judge is expected to issue his decision Thursday on its legality.

It is an Excel spreadsheet, named "Follow-up of criminal proceedings - pension reform movement" detailing the surnames, first names, dates of birth of people taken into custody. 50 to 100 arrests have taken place in the jurisdiction of Lille since March 17, when the file would have been created following the hardening of the mobilization.
