Overview

Dilworth Paxson LLP’s Plaintiff’s Rights practice dates back to the pioneer of the modern-day class action – Harold Kohn.  We have deep experience in all aspects of complex commercial, class and representative litigation from building successful litigation strategies to obtaining class certification, securing discovery, negotiating settlements, conducting trials, and handling all aspects of appeals.

Dilworth is one of the few firms to offer a 360-degree perspective as our litigators and trial attorneys routinely represent both plaintiffs and defendants in complex litigation. This experience in devising and implementing litigation and trial strategies for plaintiffs and defendants benefits our clients on both sides of the “v.”

Our team represents plaintiffs in the full range of complex matters, including:

  • Antitrust violations
  • Breaches of fiduciary duty
  • Consumer fraud
  • Contract disputes
  • Data breaches
  • Environmental law
  • ERISA matters
  • Qui Tam/whistleblower actions
  • Securities and shareholder disputes
  • Technology and privacy suits
  • Unfair and deceptive business practices

Dilworth Paxson advocates for clients of all shapes and sizes from local governments and corporate institutions to individual claimants. We leverage our vast experience across many industries and network of litigators and experts to secure the best results for our clients, whether monetary, injunctive, and/or the establishment of better corporate practices.
