Constantine Cannon's work is "uniformly excellent, and thus it is no surprise that it has led the effort that produced the largest antitrust settlement ever."

-- The Honorable John Gleeson, United States District Court for the Eastern District of New York, In re Visa Check/MasterMoney Antitrust Litigation, No. 96 CV 5238 (JG), Memorandum and Order, Dec. 19, 2004, at 34.


Overview. Our national reputation for excellence is based on our representation of clients in numerous high-profile antitrust cases. We were founded in 1994 as a boutique antitrust firm by Lloyd Constantine, the former Chief of the antitrust bureau for the State of New York , and maintain our commitment to antitrust today. Through our antitrust practice, the firm has delivered an expertise in numerous industries, including payments, telecommunications, health care, high technology, and the airline industry, among others. Many of our attorneys developed their antitrust expertise through past careers as antitrust enforcement officials with state and federal regulatory agencies. Our attorneys have taught antitrust law, testified before Congress on antitrust and international trade issues, made presentations or given speeches at seminars, industry forums, and various educational programs, and have authored books and countless articles on a variety of issues dealing with antitrust law and compliance. We offer our services from offices in New York, New York and Washington, D.C.

In addition to our core antitrust practice, our Washington D.C. office offers a sophisticated legislative affairs practice that combines the industry knowledge gleaned from our antitrust and complex commercial litigation practice with expertise regarding the legislative process in Congress. Many of our attorneys in Washington developed this expertise through previous stints as Congressional aides or staffers, where they developed expertise in various industries including telecommunications and payments.

Value. Our billing rates and total fees are typically significantly less than those charged by larger firms. We are nonetheless proud to deliver a quality of work that exceeds those firms

Areas of practice. We represent clients in antitrust litigation and counseling, commercial and complex litigation, intellectual property and technology, governmental relations, corporate compliance, labor and employment, employee benefits and trusts and estates matters.

Accomplishments. As lead counsel to a class of 5 million retailers in their suit against Visa and MasterCard , we secured the largest antitrust settlement in history, valued by the courts at between $25 and $87 billion, for our clients. We have continued to deliver outstanding results for clients - whether defendants, plaintiffs, or clients seeking counseling or lobbying services - in a wide variety of industries. Our attorneys are frequently asked to comment to the media on antitrust and other matters; we also routinely publish in legal and business publications.

Clients. We routinely represent Fortune 500 companies in high-stakes antitrust and commercial litigation. Our clients include firms in the financial services, insurance, telecommunications, health care, pharmaceuticals, retail, electronics and transportation industries. We also represent consumers, the Japanese government and numerous trade associations.
