With offices in four cities, the law firm is home to among the most prominent practices in Antitrust, Whistleblower, and Art & Cultural Property Law.

NEW YORK, NY (April 5, 2019) – Constantine Cannon LLP is pleased to celebrate its 25th anniversary.

Founded by Lloyd Constantine on April 4, 1994 as a full-service antitrust boutique, the firm has grown over the years to become one of the leading law firms in the world in three distinct practice areas: Antitrust Litigation and Counseling; Whistleblower Law; and Art & Cultural Property Law. The firm, which also has practice areas in e-discovery, commercial litigation and government affairs, is now home to 78 attorneys in New York, Washington, D.C., San Francisco, and London.

Lloyd Constantine said: “What started as one lawyer with one case has matured into a bustling firm of remarkable attorneys advocating across several practices. As we have grown, we have stayed true to our roots, and I am immensely proud of the positive impact Constantine Cannon’s first quarter century has had on consumers, clients and the rule of law.”

“In 25 years, we have established a firm that continues to set the standard of excellence in a variety of areas,” said W. Stephen Cannon, Chairman of the firm and Managing Partner of Constantine Cannon’s Washington, D.C., office. “I am proud of the firm’s legacy and strongly believe the best is yet to come for Constantine Cannon.”

In the area of antitrust law, Constantine Cannon attorneys represent clients in a range of plaintiff and defense side matters, including advocacy before antitrust agencies, shepherding mergers through consummation, antitrust compliance programs, distribution arrangements, and licensing agreements. The practice is known for its high-profile experience representing both Fortune 500 companies and small startups across industries, most notably electronic payments, healthcare and pharmaceutical, telecommunications and media, and transportation. On the plaintiffs’ side, the firm has the distinction of being lead counsel in two of the three largest antitrust settlements in history.

Jeffrey I. Shinder, Managing Partner of Constantine Cannon’s New York office, said: “Our antitrust practice continues to expand and thrive building on our legacy of bringing or defending some of the toughest cases that require a sophisticated understanding of the industries in which we specialize and the economics that impact those markets.  I am deeply proud of the quality of our work and the integrity of our attorneys.”

Constantine Cannon’s Whistleblower practice, which launched in 2015, is the largest practice group exclusively serving whistleblowers in the world, with more than two dozen lawyers counseling clients reporting fraud and misconduct. The practice represents whistleblowers under the False Claims Act; the whistleblower programs of the IRS, SEC (Dodd-Frank Act), CFTC, and DOT; as well as the complicated landscape of federal and state whistleblower programs.

In 2012, the firm expanded to London, where attorneys practice in antitrust law, commercial litigation and arbitration, art and cultural property law, and in support of international whistleblowers bringing their cases to the American justice system.

“Our work on behalf of whistleblowers is a natural extension for a firm founded on vigilant market enforcement,” said Constantine Cannon partner Eric Havian, a leader in the Whistleblower practice.

Constantine Cannon’s London office spearheads the firm’s Art and Cultural Property Law practice, one of the largest practice groups in the world exclusively dedicated to serving art collectors, art businesses and artists and their estates internationally across the entire field of art and cultural property law including art litigation, Nazi-era restitutions, cultural patrimony claims, multi-million dollar art transactions and new museum planning and management.

“This market-focused practice is a natural fit for our firm, whose understanding of the markets in which we specialize is unsurpassed. Clients of our art and cultural property practice come to us not just for our legal expertise but for our knowledge of the art sector”, said Pierre Valentin, the leader of the Art and Cultural Property Law Group.

A quarter century of cutting-edge complex litigation has seen additional areas of practice emerge at the firm. The firm’s Commercial Litigation practice has represented plaintiffs and defendants in all matters of litigation and arbitration. The Intellectual Property and Technology practice represents clients creatively expanding the legal framework of technological disruption in copyright, trademark and patent law. And the firm’s e-Discovery practice works closely with clients to tailor creative and flexible discovery plans that mitigate both cost and litigation risk.

Alysia Solow, founding Partner of the e-Discovery Practice, said, “We are proud that Constantine Cannon has been at the forefront of discovery theory and practice in the information age throughout its 25-year history.”

“Our anniversary provides an opportunity to reflect on the tremendous success our firm has achieved,” Richard Aborn, Managing Partner of Constantine Cannon, said. “Constantine Cannon has produced results that reshape industries, influence legislation, and chart new courses for commercial innovation. We are proud to mark this milestone in our firm’s history and look forward to many exciting chapters to come.”
