Mr. Nannes returned to the firm in 2001. Since his return, Mr. Nannes has worked on a variety of merger matters, many of which have had international dimensions and involved the European Commission and various other competition agencies around the world. He also has represented a number of companies in connection with U.S. and international cartel investigations and in multidistrict treble-damage litigation.
