Mark T. Stancil is a partner in the Litigation Department and member of the Appeals & Strategic Motions Practice Group. He is also Co-Chair of the Bankruptcy Litigation practice. He focuses on trial and appellate advocacy in complex commercial litigation, with a particular focus on investment disputes.
A substantial portion of his practice is devoted to representing hedge funds; multi-strategy asset managers; and various trustees, agents, and ad hoc groups with significant financial interests in the outcome of litigation.
Mark’s cases often involve novel questions of law and complex financial transactions, and frequently implicate bankruptcy disputes or legal rights and priorities arising under bond indentures or similar instruments. He has served as lead litigator at every level of the federal judiciary, arguing significant and case-dispositive motions in multiple district courts, and briefing and arguing numerous appeals before the U.S. Courts of Appeals for the First, Second, Third, Fourth, and Ninth Circuits.
Mark has also argued five cases before the Supreme Court of the United States, briefed many more, and filed scores of briefs at the certiorari stage.
In addition to investment disputes, Mark has litigated a wide variety of issues including the Foreign Sovereign Immunities Act, constitutional claims, the Hatch-Waxman Act, partnership tax controversies, intellectual property litigation (copyright, trademark, and trade secrets), Section 1983 litigation and qualified immunity, federal securities disputes, accounting fraud and accounting regulatory matters, SEC disclosure issues, and the Alien Tort Statute.
Mark was named a Litigation Star by Benchmark Litigation (2023-2026). Chambers USA (2023-2026) recognizes Mark as a leading practitioner in the area of Litigation: General Commercial (District of Columbia).
