Justin Cohen is an associate in the Litigation Department. His practice focuses on complex civil and commercial litigation, as well as securities litigation and enforcement. He has represented clients in a variety of industries—including financial services, healthcare, food and agriculture, and engineering and construction—in both federal and state courts across the United States, and in investigations by the SEC and DOJ.

Justin earned his J.D. from Columbia Law School, where he was an Articles Editor for the Columbia Science and Technology Law Review. He served as a Teaching Fellow for the Foundation Moot Court program, and as President of the National Security Law Society. While at Columbia, he worked at the U.S. Attorney’s Office for the Eastern District of New York.

Prior to joining Proskauer, Justin practiced at Paul, Weiss, Rifkind, Wharton & Garrison LLP in New York. Before law school, Justin worked as an analyst for the U.S. Department of Defense.

Last month, TikTok sued Montana’s attorney general—alleging the state’s recent TikTok ban is unconstitutional and is preempted by federal law.

On May 17, Montana Governor Greg Gianforte signed a first-of-its-kind law banning TikTok from operating in the state, in order “[t]o protect Montanans’ personal, private, and sensitive data and information from intelligence gathering by the Chinese Communist Party.”

In late-July, the U.S. Securities and Exchange Commission brought insider trading charges against a former manager at Coinbase—the largest crypto asset trading platform in the United States. The charges are the latest move in the agency’s efforts to regulate cryptocurrency, and could spur an increase in cryptocurrency-related securities litigation.
