Larry Ebner is a steadfast and accomplished advocate for business and industry in federal and state appellate courts throughout the United States. Individual corporations, national trade associations, and professional organizations call upon Larry when they need an experienced and articulate voice in the U.S. Supreme Court, federal courts of appeals, and state appellate courts. After more than 40 years as a Washington, D.C.-based appellate litigator and practice leader at a major law firm, Larry launched his own, nationwide, appellate litigation boutique, Capital Appellate Advocacy PLLC. Larry also serves as Executive Vice President & General Counsel of the Atlantic Legal Foundation. He is a graduate of Dartmouth College and Harvard Law School.

Clients and colleagues praise Larry for his strategic thinking, as well as for his hands-on approach and analytical, brief-writing, and oral advocacy skills. He has authored hundreds of briefs on complex legal issues - including many amicus curiae ("friend of the court") briefs - and presented oral arguments in numerous federal and state appeals courts. Much of Larry’s practice focuses on appeals  that  implicate significant federal interests, such as national defense or federal regulation of potentially hazardous products, and civil justice issues, such as class-action fairness. Larry is particularly well known for his expertise on federal preemption of state and local law.

Larry’s thought leadership is reflected in his prolific professional writing and speaking. He is active in DRI-The Voice of the Defense Bar, where he serves as Vice Chair of the Center for Law and Public Policy, Immediate Past Chair of the Amicus Committee and an author of Supreme Court amicus curiae briefs and appellate practice-related articles for that 18,000-lawyer organization. He also has been elected as a member of the Federation of Defense & Corporate Counsel. In recognition of his appellate litigation achievements, Larry has been selected to the 2018 Washington DC Super Lawyers list.

Larry began his legal career in 1974 as an Honors Program attorney in the Civil Division of the U.S. Department of Justice.
