Mark Grannis is the managing partner of Wiltshire & Grannis LLP, handling an eclectic mix of litigation, telecommunications, and appellate cases.

As a litigator, Mr. Grannis has handled a very wide range of civil cases, including commercial disputes, constitutional litigation, election contests, product liability claims, antitrust issues, and probate matters.  Mr. Grannis has litigated in a large number of federal, state, and territorial courts. In recent years, he has focused primarily on financial services litigation, both prosecuting and defending claims for breach of fiduciary duty.  He also has significant experience litigating the issues of privacy, reputation, and open public discourse that arise when journalists or government officials abuse their positions in society to the detriment of ordinary citizens.  His work in this area includes two cases that grew out of the investigation of the anthrax attacks of 2001: Hatfill v. Ashcroft, and Hatfill v. The New York Times Company.  He has been recognized in Washington, DC and Baltimore’s Top-Rated Lawyers in the field of Litigation, with an AV rating from Martindale-Hubbell, and by Super Lawyers magazine in the field of General Litigation.

Mr. Grannis also has extensive experience within the field of telecommunications regulation.  He has represented equipment manufacturers and service providers in matters before the Federal Communications Commission, primarily in the area of radiofrequency spectrum management.  These representations have frequently required complementary efforts at the International Telecommunication Union, the U.S. Departments of State and Commerce, and with foreign regulatory authorities.  He is a member of the federal advisory committee that provides private-sector input to the State Department, the Commerce Department, and the FCC regarding the positions taken by the United States in matters of international spectrum policy, and on occasion has served on U.S. delegations to international conferences where such matters are debated and decided.

In addition, Mr. Grannis has advised clients both inside and outside the telecom industry in connection with the federal "Do Not Call" rules and other telemarketing regulations administered by the FCC and the Federal Trade Commission.  These engagements range from top-to-bottom policy reviews, to counseling on specific compliance questions, to defense of specific enforcement actions.  He appears in Euromoney's Guide to the World's Leading Technology, Media & Telecommunications Lawyers.

Mr. Grannis's appellate experience includes cases in the United States Supreme Court, several U.S. Courts of Appeals, and appellate courts in California, New York, and Maryland.  These cases have raised issues as common as the review of administrative agency decisions and as esoteric as the proper interpretation of the Bill of Attainder Clause.
