William C. Sammons

Bill has been practicing law with Tydings for 50 years.  Although he began as a general business practitioner representing clients in both litigation and transactional matters, for almost three decades his practice has been limited to civil litigation, with an emphasis on antitrust, business torts, employment, securities law, real estate, and other business litigation.  He has tried cases in federal and state courts throughout Maryland and elsewhere, and has represented clients before arbitration panels and in a variety of administrative courts, with particular focus on matters before the Maryland Tax Court.   Prior to joining Tydings, Bill clerked for the Honorable William J. McWilliams, Associate Judge of the Maryland Court of Appeals.

Representative Matters

  • Represented one of the world’s largest pension funds in litigation involving ownership interests in a real estate portfolio valued in excess of one-half billion dollars.  At trial, the pension fund prevailed against a joint venture partner, convincing the Court that the partner no longer had an interest in the portfolio, and that the pension fund was the sole owner.
  • Defended a major automobile manufacturer in a series of antitrust cases that challenged the manufacturer’s parts distribution practices.
  • Represented a Fortune 100 telecommunications company in litigation concerning the constitutionality of a portion of the Maryland sales and use tax.  Starting in the Maryland Tax Court, the case ended at the Maryland Court of Appeals, where the Court agreed with the client that the assessment of the tax violated the Commerce Clause of the U.S. Constitution, thereby defeating the state’s $10 million tax claim.
  • During most of his career has represented a Fortune 50 technology company in Maryland litigation matters involving employment issues, contract disputes, discrimination claims, and other business disputes.
  • For six years, served a large public pension fund as lead litigation counsel in connection with its commercial real estate portfolio.  Cases included landlord-tenant matters, use covenants, and the like.
  • Represented various clients in employment cases including discrimination (race, sex, national origin), cases under the ADEA and the ADA, WARN Act cases, wrongful discharge cases, and cases involving covenants not to compete.
  • Represented a Russian professional hockey club in enforcing an international arbitration award against a U.S. hockey team and its star player.
  • Represented various clients in disputes involving business torts, corporate governance issues, fiduciary duty, professional negligence, securities law violations, state and local taxation, and a variety of other business issues.

Bill has also been involved in business counseling in a variety of areas, particularly antitrust and employment law.  He has lectured clients and others in matters relating to product distribution, employment discrimination, and wrongful discharge.
