Timothy J. Simeone



Tim Simeone is a partner with the law firm of Harris, Wiltshire & Grannis LLP.  Mr. Simeone has argued cases on a wide variety of issues before the United States Supreme Court, the D.C. Circuit, and other federal courts of appeals.  Mr. Simeone has also argued before a number of state courts of last resort, the U.S. Court of Claims, and the District of Columbia Board on Professional Responsibility.

In over twenty years as an appellate advocate, Mr. Simeone has honed the skill of presenting complex legal issues simply, both orally and in writing.  His briefs have addressed matters of federal jurisdiction, constitutional law, attorney discipline, administrative law, contract, criminal procedure, trade secrets law, insurance issues, antitrust, ERISA, defamation, telecommunications law, election law, indecency and obscenity, bankruptcy, and many other areas.

Mr. Simeone’s most noteworthy appellate representations include:

  • Obtaining a grant of certiorari and then winning a 9-0 decision in the first major federal abstention case in the United States Supreme Court in more than twenty years;
  • Obtaining vacatur and a new trial in a high-profile appeal of a first degree murder conviction in the D.C. Circuit;
  • Successfully defending an attorney in a disbarment appeal before the D.C. Court of Appeals;
  • Briefing and arguing a trade secrets case before the Delaware Supreme Court;
  • Successfully representing attorneys on appeals of disciplinary cases before the D.C. Board on Professional Responsibility;
  • Crafting an amicus strategy along with the HWG appellate team and preparing a series of Supreme Court and Federal Circuit briefs in patent law cases for a large technology firm;
  • Arguing on behalf of a major national wireless carrier in telecommunications appeals before multiple federal courts of appeals.

Mr. Simeone is also a member of HWG’s Trial Litigation group, where his appellate experience is valuable for analyzing legal issues, preparing, defending, and arguing dispositive motions, and preserving arguments for appeal.  Mr. Simeone has experience writing down-to-earth mediation statements in complex commercial mediations.

Mr. Simeone has worked with HWG’s Communications practice on a wide variety of legal and regulatory issues before the FCC.  Like his work in trial courts, Mr. Simeone’s advocacy at the FCC draws on his experience as an appellate attorney to present analysis of complex legal and policy issues as straightforwardly as possible.

Before joining HWG, Mr. Simeone spent the 2000-2001 academic year as a Visiting Professor at Villanova University Law School.  He had previously practiced at a large Washington, D.C. law firm where he worked on appellate and telecommunications matters, and also took a hiatus from private practice to serve as a full-time legal consultant to the Antitrust Division of the Department of Justice in connection with the Microsoft litigation.
