In July 2014 the Commission nationale de l’informatique et des libertés (CNIL) indicated that it would launch, in October 2014, an in-depth investigation into compliance with cookie regulations. This forms part of its investigation program for 2014, which was announced in April 2014, and its participation in the Mobile apps Sweep day organised by the Global Privacy Enforcement Network. This follows a change in law, on 17 March 2014, which gave wider powers to the CNIL to carry out investigations. Previously, the CNIL’s powers were limited to on-site inspections, document reviews and hearings.
