US Treasury says Tornado Cash sanctions illegal...cannot be sanctioned again

A Texas federal court has ruled that the U.S. Treasury Department's sanctions against the cryptocurrency mixing service Tornado Cash are illegal.
On the 28th (local time), Robert Pittman, US District Court for the District of Austin,
In his ruling, Judge Pitman said, "The Tornado Cash sanctions imposed by the Treasury Department's Office of Foreign Assets Control (OFAC) are not in accordance with the law.
The suit was brought by Tornado Cash user Joseph Van Loon, who filed suit in 2013 against the company.
The lawsuit was brought by plaintiffs including Robert O. Roseph Van Loon, who argued that OFAC had designated TornadoCash’s smart contract addresses as “Specially Designated Nationals and Blocked Persons (SNCs).”
OFAC's August 2022 ruling that Tornado Cash was linked to the North Korean hacking group Lazarus Group was unlawful.
However, on March 21, OFAC removed Tornado Cash from the sanctions list, saying, "The problem is over."
The ruling makes it clear that the sanctions themselves are illegal and that OFAC cannot reinstate them or relist them again in the future.
This case is accepted as a precedent that has put a major brake on policies targeting cryptocurrency-related codes and smart contracts in the United States.
