Roman Storm, co-founder of Tornado Cash, has filed a motion for judgment of acquittal in the Southern District of New York. The motion, submitted on September 30, argues that the Department of Justice is improperly criminalizing open-source code, infringing on First Amendment rights. Storm was previously convicted of operating an unlicensed money-transmitting business, though jurors were deadlocked on money laundering charges and acquitted him of sanctions violations. Storm's defense contends that Tornado Cash is immutable software beyond his control once deployed, and criticizes the government's reliance on a negligence theory. The Department of Justice has until October 31 to respond to the motion.
