He worked frequently on antitrust problems associated with network industries such as airlines, securities and railroads. Since his return to the firm, Mr. Nannes has worked on similar matters, most of which have had international dimensions and involved the European Commission and various other competition agencies around the world, and he also has represented a number of companies in connection with U.S. and non-U.S. cartel investigations.
As deputy assistant attorney general, Mr. Nannes supervised activities of the division’s sections responsible for reviewing merger and civil nonmerger activities in transportation, energy, securities and financial markets, among others. As acting assistant attorney general, he supervised activities of all the division’s civil sections and also handled criminal matters.

He clerked for Judge Roger Robb on the United States Court of Appeals for the District of Columbia Circuit in 1973-1974 and then for Justice William H. Rehnquist on the Supreme Court of the United States in 1974-1975. He served as a special assistant to the assistant attorney general in charge of the Antitrust Division for a year before joining Skadden, Arps when it opened its office in Washington in 1977.
Mr. Nannes has taught basic antitrust and advanced antitrust at Georgetown University Law Center. He is a trustee of the Legal Aid Society of Washington, D.C. and of the Supreme Court Historical Society. He previously served for six years on the pro bono committee of the District of Columbia bar.
