Our work on these matters includes advising and representing clients in highly controversial contexts (including through litigation and injunctive relief) which in many cases resulted in landmark antitrust decisions and rulings.
We also represent our clients in a large number of investigations and government enforcement actions initiated by competent governmental authorities (both at the administrative and judicial levels, including proceedings before the Supreme Court), such as investigations related to price fixing and discrimination, market division, predatory pricing, exclusionary and collusive practices, and abuse of dominant position in general.
