Class Action & Multidistrict Litigation

Print PDF


With potential exposure that may climb into the billions of dollars, class action and multi-district litigation can threaten the life of a business. Such litigation is often accompanied by governmental investigations, and few firms have the sophistication and experience to manage both complex civil litigation and regulatory exposure. RK&O has over 25 years’ experience delivering positive outcomes for our clients in such cases, from obtaining dismissal of claims and reducing the scope of our clients’ potential liability, transferring and consolidating actions in favorable forums, managing broad-gauge discovery and achieving favorable outcomes through dispositive motions or settlements. more +

Clients have repeatedly turned to RK&O for high-stakes class action and multi-district litigation, including cases involving:

  • Securities fraud
  • Antitrust
  • Derivatives claims
  • Civil RICO

One of our group’s strengths is our deep knowledge of federal court practice, civil claims and regulatory enforcement. This allows us to develop and execute a comprehensive strategy that anticipates and protects our clients from the civil actions that often run concurrent with government investigations. Our litigators, who greatly benefit from a close collaborative relationship with our Chambers-cited white collar and regulatory groups, are recognized by clients for deftly handling government investigations.
