MLAB is renowned for its expertise in competition law, rooted in the extensive professional experience of our lawyers, their strong educational backgrounds and permanent commitment to continuing study of the field. 

At MLAB, we approach each case as if it were our only assignment at the time. We work to get a full command of the specific circumstance of each client and respective industry, conducting thorough analyses of the concrete conducts in each case and their competition law implications.

We have ample experience in assisting companies during dawn raids by competition authorities and in preparing leniency applications and settlements.
