Securities Litigation

Williams & Connolly’s securities practice has established a national reputation by bringing the law firm’s focus on trial excellence to litigation involving the securities laws.  Although we frequently win cases on motions to dismiss, we have built our reputation on our ability to prevail when preliminary motions have been unsuccessful and our courtroom experience and reputation allow us to achieve successful outcomes. 

Securities cases pose among the most challenging and complex issues our clients face.  We are proud that leading corporations, private equity firms, financial institutions, accounting and law firms, directors, and officers place their trust in us to represent them in these matters.  These disputes can also often involve overlapping government investigations or proceedings, where we work with our securities enforcement and criminal securities fraud practices to provide integrated and comprehensive representation of clients facing issues arising under the securities statutes. 

The law firm’s securities representations involve suits of all types, including class actions proceeding in federal and state courts (and under federal and state law), derivative actions, and common-law and statutory shareholder disputes.  We have extensive experience litigating disputes arising under the Securities Act of 1933 and the Securities Exchange Act of 1934, as well as common law and derivative theories of liability against corporations, officers, and directors.  We also routinely represent individual directors, officers, and professional firms in securities matters.

We have litigated securities actions across the country and around the globe.  Clients have called on Williams & Connolly to take over securities cases after a loss on appeal or a motion to dismiss, to argue securities cases in the Supreme Court of the United States and the courts of appeals, and to litigate and win cases from the outset.  We also assist clients in the preliminary stages of such litigation, including in navigating the issues arising from investigations by plaintiff-side securities law firms and responding to requests from shareholders.
