Antitrust and Competition Law Litigation (Domestic / Overseas)

Traditionally, petitions for injunctions, provisional dispositions and claims for damages have been filed in response to violations of the antitrust laws by companies subject to investigations by the authorities regarding such violations. As the number of exposed cases of cartels, bid-rigging and abuse of dominant position increases, the number of civil litigations related to these cases is also on the rise. Further, there are a number of cases where petitions for injunctions, provisional dispositions, and claims for damages have been filed with respect to the business activities of companies that are not subject to investigations or enforcement actions by the authorities.

Atsumi & Sakai provides consultation on civil litigation related to antitrust violations, working in collaboration with our Civil Litigation Team and our Crisis & Risk Management Practice Group to serve clients both as plaintiffs and defendants. We also assist with the defense of class-action lawsuits against corporations, as well as criminal defense in antitrust violation cases and provide consultations regarding criminal complaints.

In cases involving international cartels or violations of foreign competition laws, claims for damages may be filed overseas (such as in U.S. class action lawsuits) in parallel with proceedings before regulatory authorities. With private action risks in mind at an early stage of responding to regulatory proceedings, including “litigation holds,” we leverage our international network as well as our Antitrust and Competition Law Team’s unique network of experienced international attorneys to assist clients in establishing an international response team.
