In a decision dated 17 April 2019, the Conseil d’Etat (the Supreme Administrative Court) confirmed a decision of sanction issued by the French Data Protection Authority (the CNIL) but reduced the amount of the sanction from €250,000 to €200,000.
This decision gives precious guidance: in case of a data breach, the implementation of corrective measures is an argument to obtain a reduction of a fine in case of further prosecution by the CNIL.
