Litigation & Investigations
Today’s headlines tell the story of a world transformed—by technological revolution, worldwide geopolitical and environmental threats, uncharted economic territory, and an evolving legal and social landscape.
In the face of accelerating change, O’Melveny’s litigation and investigations practice has the experience to decipher the present and anticipate the future. We are strategic advisers, trusted investigators, veteran negotiators, and trial-ready litigators—a suite of services to help clients navigate complex legal and regulatory environments, minimize risk, and protect their interests.
The American Lawyer lauds our litigation teams, noting we have “excelled in cases ‘ripped from the headlines’” and have been “front and center in massive, high-profile matters.” As a perennial honoree in the publication’s Litigation Department of the Year competition, we regularly earn recognition for our strategic approach to novel and complicated legal challenges and our versatility in and out of the courtroom.
We also receive acclaim for our ability to handle sensitive and complex defenses to government inquiries and allegations of employee misconduct. Our investigations teams represent corporations, board committees, and individual officers and directors in congressional, SEC, DOJ, attorney general, self-regulatory, and internal investigations.
When confronted with litigation, we help our clients prevail at every stage: on the pleadings, at trial, in settlements, and on appeal. Most years, our victories span all US jurisdictions, including courts in nearly every state, every federal circuit, multiple arbitral forums, government agencies in Europe and Asia, and the US Supreme Court.
While clients value our willingness to go to the mat for them, we never lose sight of their business interests. Some of our biggest litigation successes have meant helping a client avoid litigation altogether.
In an ever-evolving landscape, O’Melveny’s teams help clients navigate challenges and uncertainties while safeguarding their interests with strategic precision and unwavering dedication.
