Adam Sieff is a media, antitrust, and constitutional litigator. A recognized thought leader on emerging issues involving online speech and competition regulation, he represents internet, media, and technology clients in antitrust, First Amendment, Section 230, copyright, trademark, and regulatory litigation and appeals, including preemption matters and constitutional challenges to state and local regulation. He also counsels clients on legislation, ballot initiatives, and compliance with competition laws, and represents nonprofit and issue-advocacy organizations in constitutional rights, voting rights, and civil rights impact litigation, including before the U.S. Supreme Court.
Outside his practice, Adam is a lecturer in law at the University of Southern California, where he teaches courses that cover constitutional law and civil procedure. A member of the ABA Section of Antitrust Law and Vice Chair of the LACBA Antitrust and Unfair Competition Section, he also serves as Executive Vice Chair of the American Constitution Society in Los Angeles, on the boards of the Jewish Public Affairs Committee of California, Bet Tzedek's New Leaders Council, and the Los Angeles County Young Democrats, among other statewide and community nonprofit and political action organizations. The Los Angeles County Empowerment Congress has named Adam a "40 Under 40: Emerging Civic Leader," and Equality California honored him with its Community Leadership Award.
Prior to joining DWT, Adam served as voting rights and election integrity litigation counsel to the Biden for President campaign, practiced for several years in the San Francisco and Los Angeles offices of an international law firm, and clerked for the Hon. Christina A. Snyder of the U.S. District Court for the Central District of California.
