Investigation and Procedure

If you have a question about your file, observations to communicate on a merger case ... Our staff is here to help you.


If your company participates or has participated in an anticompetitive agreement, applying for leniency can help you avoid a heavy fine by revealing these practices to the Autorité or by providing it with information which it did not previously have.
