Antitrust Dispute Resolution

World class antitrust expertise to guide billion-dollar disputes to resolution

Antitrust Disputes Demand Expertise and Efficiency

Antitrust litigation is among the most complex and consequential areas of law. Merger challenges, price-fixing, and monopolization disputes can sprawl across jurisdictions, involve thousands of plaintiffs, and put billions of dollars — and reputations — at risk.

Expertise at every stage can make all the difference. Experienced neutrals with world class stature can help prevent disputes through opinions to government agencies, oversee compliance with consent decrees, and resolve class actions through active mediation and ongoing work as a special master.

Counsel and clients need experts who understand competition law and can guide efficient, credible resolution at every stage of an antitrust dispute. That’s where FedArb comes in.
