U.S. Appeals Court Overturns Tornado Cash Sanctions, Declares Software Beyond Treasury’s Reach

The three-judge panel’s ruling determined that Tornado Cash’s immutable smart contracts—self-executing lines of code enabling privacy for Ethereum transactions—do not qualify as “property” under the International Emergency Economic Powers Act (IEEPA). Judge Don Willett emphasized that federal law allows the Treasury to target property, not technology.

In its judgement, the court lamented the inability of legislative changes to keep up with the pace of change in the technology sector – a global problem that is especially marked in the United States given the lawmaking gridlock that has impacted successive US administrations. “Perhaps Congress will update the law, enacted during the Carter Administration, to target modern technologies like crypto-mixing software. Until then, we hold that Tornado Cash’s immutable smart contracts…are not the ‘property’ of a foreign national or entity,” Willett stated.

The Office of Foreign Assets Control (OFAC) sanctioned Tornado Cash in August 2022, citing its use in laundering over $7 billion in cryptocurrency, including $455 million linked to North Korea’s Lazarus Group. However, the court concluded that the sanctions unlawfully targeted open-source software rather than individuals or entities misusing it.

The plaintiffs, six Tornado Cash users backed by Coinbase, claimed that the platform’s smart contracts could not be owned or managed and hence should not have been listed as a Specially Designated National (SDN). The court agreed with the plaintiffs, ruling that OFAC’s activities violated its powers under the IEEPA.

Bill Hughes, senior counsel at Consensys, remarked, “These smart contracts are not ownable and therefore cannot be blocked under federal law.”

The decision is celebrated as a milestone for privacy rights within the cryptocurrency sector. Coinbase’s Chief Legal Officer Paul Grewal called it a “historic win for crypto and liberty.” He added, “This victory reaffirms that courts will defend the rights of individuals using open-source tools responsibly.”

Brian Armstrong, CEO of Coinbase, also praised the ruling, asserting that the Treasury’s sanctions had “exceeded its authority” by targeting software rather than its misuse.

Following the landmark decision, Tornado Cash’s governance token, TORN, enjoyed a massive spike, demonstrating market confidence. The token began trading at around $3.6 before rising to a two-year high of nearly $35, signifying a rise of approximately 870%. According to Brave New Coin data, it had stabilized around $16.7 by Wednesday morning.

The recent price surge reflects the market’s reaction to the Fifth Circuit Court’s judgment, which many see as a watershed event for the cryptocurrency industry as a whole. Despite TORN’s controversial history, researchers believe the verdict will increase investor confidence in blockchain-based privacy tools.

Regulatory scrutiny around Tornado Cash persists even after the legal victory. The court acknowledged that the sanctions did not entirely block access to the service, which remains operational and accessible to anyone with an internet connection.

“This ruling only applies to the smart contracts,” Hughes clarified. “Other components of Tornado Cash’s operations could still face legal challenges.”

The Treasury Department has yet to indicate whether it would appeal the ruling. Meanwhile, the case shows persistent difficulties between regulators and the cryptocurrency industry, as governments struggle to balance privacy rights and anti-crime efforts.
