Washington, D.C. partners Ryan Duffy and Kathleen Warin and associate Nate Lefko obtained summary judgment in the District of Columbia Superior Court on behalf of the Financial Industry Regulatory Authority (FINRA). The plaintiff sought to expunge decades-old customer complaints from his registration records and requested wide-ranging equitable relief, including equitable expungement, declaratory judgment, and a permanent injunction. The Wilson Elser team successfully demonstrated that the doctrine of laches barred all the plaintiff’s claims. In granting summary judgment, the Superior Court found that the plaintiff delayed in bringing his claims and material evidence had been lost, which resulted in prejudice to FINRA.
