Treasury Lifts Tornado Cash Sanctions, But Legal Uncertainty Persists

The US Treasury's recent decision to lift sanctions on Tornado Cash has brought a mix of relief and caution to the cryptocurrency community. While the move is seen as a victory for decentralization advocates, Coinbase’s Chief Legal Officer, Paul Grewal, has raised concerns about the potential for future sanctions. Grewal cautions that the lifting of sanctions does not guarantee long-term protection against arbitrary regulatory actions. He emphasizes the need for a court ruling to secure lasting legal safeguards for Tornado Cash.

The revocation of sanctions on Tornado Cash marks a significant shift in regulatory stance, following extensive public scrutiny and legal challenges. Initially, the US Treasury accused Tornado Cash of facilitating money laundering activities linked to North Korea. However, the legal pushback has led to the current decision to remove the restrictions. Despite this positive development, Grewal highlights that the Treasury’s action is not a definitive safeguard. He asserts that the legal framework does not guarantee Tornado Cash will remain free from renewed sanctions without a clear judicial ruling.

Grewal points to established legal precedents, such as the voluntary cessation doctrine, which argues that a defendant’s withdrawal from a contested practice does not moot existing claims. This suggests that even with current sanctions lifted, the risk of future actions by the Treasury remains. He draws parallels with notable court cases, such as FBI v. Fikre, where a court ruled that a plaintiff’s removal from a blacklist did not moot the case due to the lack of assurance against future listings. Such examples illustrate why a definitive ruling is necessary to ensure that Tornado Cash is not subject to arbitrary sanctions again.

In light of these concerns, Grewal calls on the district court to provide clarity. He argues that the court should grant a motion for partial summary judgment that would invalidate the previous designation of Tornado Cash as a sanctioned entity. This action is pivotal in safeguarding the future of Tornado Cash users and the integrity of the cryptocurrency ecosystem. “The US Treasury’s chaotic response to the Fifth Circuit’s direction on Tornado Cash underscores the urgency for the district court to act. Granting the plaintiffs’ motion for partial summary judgment would be a critical move to affirm Tornado Cash’s legality,” Grewal stated emphatically.

The lifting of sanctions is seen as a boon for users and advocates of decentralization. However, the specter of renewed regulation looms large. Without a final judicial ruling, the legal standing of Tornado Cash remains precarious, and the implications may resonate across decentralized finance (DeFi) platforms and privacy protocols. As the debate continues, voices from the crypto community emphasize the necessity of judicial intervention. Grewal and others urge for protective measures to be established to prevent the Treasury from exerting arbitrary authority over Tornado Cash and similar entities in the future.

In summary, the removal of sanctions on Tornado Cash represents a pivotal moment for the cryptocurrency industry, but the implications are far from settled. The call for a definitive court ruling is not only about ensuring the legal status of Tornado Cash but also about preserving the freedoms associated with decentralized finance. As Grewal emphasizes, without strong judicial protections, the risk of arbitrary re-imposition of sanctions remains a significant concern for the future of crypto innovation.
