Washington, D.C. partners Ryan Duffy and Kathleen Warin secured an appellate victory on behalf of the Financial Industry Regulatory Authority (FINRA) after obtaining dismissal of the plaintiff’s claims in federal district court. The plaintiff brought a number of claims against FINRA, including defamation related to a prior arbitration held in FINRA’s arbitration forum. After years of motions practice in the United States District Court for the District of Columbia, the court granted FINRA’s motion to dismiss, found the plaintiff’s claims were barred by the statute of limitations and arbitral immunity, and denied the plaintiff’s requests for leave to further amend the complaint. The plaintiff appealed to the United States Court of Appeals for the District of Columbia Circuit, where the Wilson Elser team obtained summary affirmance in a per curiam decision. The D.C. Circuit found that the district court properly concluded that the statute of limitations barred the claims at issue and that the plaintiff-appellant failed to plausibly allege any exceptions to avoid application of the statute of limitations. This led the D.C. Circuit to grant FINRA’s motion for summary affirmance.
