In a closely watched and complicated case, Van Loon et al. v. Dep’t of the Treasury et al., the U.S. Court of Appeals for the Fifth Circuit ruled that the Office of Foreign Assets Control (“OFAC”) cannot sanction Tornado Cash, “an open-source, crypto-transactions software protocol that facilitates anonymous transactions by obfuscating the origins and destinations of digital asset transfers.” The opinion, which reversed the ruling of the District Court, is here. A recording of the oral argument is here. The opinion is complex but written in a very clear style.
We previously blogged on OFAC’s designation of Tornado Cash (here) and the resulting civil suit (here). We also covered the indictment returned against the alleged developers of Tornado Cash, Roman Storm and Roman Semenov, who were charged with conspiring to commit money laundering, operating an unlicensed money transmitting business, and violating sanctions under the International Emergency Economic Powers Act, or IEEPA (here). The DOJ subsequently obtained a superseding indictment against Storm only (here); Storm’s trial currently is scheduled for April 2025). When the initial indictment was unsealed, Treasury simultaneously sanctioned Semenov, who remains outside the U.S., by adding him to OFAC’s Specially Designated Nationals and Blocked Persons (“SDN”) List.

And, invariably, people are involved in a technology.
