Donald I. Baker, a former head the Antitrust Division of the U.S. Department of Justice, established an independent Washington firm specializing in antitrust, competition policy and international law issues. His firm works closely with corporate law departments and law firms in handling litigations, appeals, arbitrations, transactions and government civil and criminal investigations. 

Mr. Baker is the only modern member of the career Antitrust Division staff to be appointed Assistant Attorney General in Charge of the Antitrust Division. He was a Trial Attorney and Section Chief, and Deputy Assistant Attorney General for Regulated Industries, Appeals and Foreign Commerce, before becoming Assistant Attorney General. During Mr. Baker's time in the government, he became a very active participant in successfully urging deregulation of US airlines, eliminating cartel pricing on stock exchanges, and in bringing the antitrust case that ultimately broke up the AT&T telephone monopoly. 

Mr. Baker was Professor of Law at Cornell Law School, where he taught courses on antitrust law, utility regulation, financial services regulation, and international business transactions. Thereafter, he was a Washington partner of two major law firms before starting Baker & Miller in 1995. 

As an antitrust lawyer in Washington, Mr. Baker’s efforts have included all aspects of antitrust counseling; representing complainants as well as targets (or merger parties) in various government investigations; corporate internal investigations; major arbitrations; and several private antitrust cases for plaintiffs and defendants. His firm’s efforts have dealt with cartels, joint ventures, mergers, IP licensing, network disputes and international transactions. He has briefed and argued cases in the U.S. Supreme Court and several U.S. Courts of Appeal. Mr. Baker is co-author of two treatises that have been regularly reissued in the new editions—Baker & Brandel, The Law of Electronic Funds Transfer Systems and Rowley & Baker, International Mergers—The Antitrust Process. 

In recent years, Mr. Baker has given lectures at various universities including Oxford, Cambridge and London universities in the UK, and Columbia, New York, George Mason, and American universities in the U.S. He has also served as a speaker for the World Bank and UNCTAD at various conferences for government enforcement officials in Asia, Africa and Latin America. Mr. Baker has written articles and letters on politics, liberty issues and competition that have been published in The Financial Times, The Global Competition Review and other international publications.

He is currently serving as a Non-Governmental Advisor to the International Competition Network, working primarily on merger processes and monopoly enforcement issues. Mr. Baker has also represented the governments of Australia, Switzerland and the United Kingdom in briefing international jurisdictional issues before the U.S. Supreme Court and Courts of Appeals. Previously Mr. Baker served as special advisor to the Anti-Monopoly Committee of Ukraine and the Government of Mongolia on establishing new rules and enforcement mechanisms. 

Since 2006, Mr. Baker has served on the Scientific Committee for the Ligue Internationale du Droit de la Concurrence (“LIDC”), an association of primarily European competition and IP lawyers, headquartered in Geneva. 

In 2008, Mr. Baker led the LIDC working group that submitted comments to the European Commission on its white paper concerning private damage recoveries for antitrust violations. He has previously been an officer in the International Bar Association and the International Section of the American Bar Association.

Mr. Baker is a member of the Panel of Distinguished Neutrals (arbitrators, mediators, etc.), appointed by the CPR Legal Program to Develop Alternatives to Litigation. He has served as arbitrator, mediator or counsel in various ADR processes. 

In 1988, Mr. Baker received the CPR Award for Significant Practical Achievement in Alternative Dispute Resolution as a result of some innovative procedures that he and his co-counsel created for use in the Financial Interchange arbitration (dealing with an antitrust challenge to interchange fees on a major banking network).
