US DOJ Rejects Roman Storm's Motion to Dismiss Tornado Cash Case

Federal prosecutors have officially rejected a motion to dismiss the criminal case against Roman Storm, the co-founder of the sanctioned cryptocurrency mixer Tornado Cash. In a filing submitted on Tuesday, the US Department of Justice (DOJ) countered defense arguments that sought to draw parallels between the privacy protocol and traditional internet service providers. The legal battle centers on allegations that Storm and his colleagues operated an unlicensed money-transmitting business and facilitated money laundering for sanctioned entities, including North Korean hacking groups.

The Supreme Court Precedent Debate

The defense recently attempted to bolster their motion to dismiss by citing a March 25 Supreme Court ruling regarding music copyright. In that specific case, the court found that the internet service provider Cox Communications was not liable for copyright infringement committed by its users. Storm’s legal team argued that, much like an ISP, Tornado Cash developers should not be held responsible for the illicit actions of third parties who utilize their open-source software.

However, federal prosecutors informed Judge Katherine Polk Failla that the comparison is fundamentally flawed. The DOJ highlighted several key distinctions:

• The Cox case involved a service provider that actively blocked infringement and terminated accounts associated with violations.
• In contrast, prosecutors allege Storm and his team failed to intervene or implement controls.
• The government asserts that the defendants had knowledge that Tornado Cash was being utilized by criminal elements for laundering digital assets.

Operational Differences and Regulatory Implications

The DOJ's letter emphasizes that whereas Cox took steps to mitigate illegal activity, the creators of Tornado Cash allegedly maintained a hands-off approach despite being aware of the protocol's exploitation. The government maintains that the developers' failure to implement Anti-Money Laundering (AML) and Know Your Customer (KYC) protocols distinguishes the platform from neutral infrastructure providers. Furthermore, the prosecution stated there is no evidence that services like Tornado Cash operated with the same level of compliance or oversight as regulated telecommunications entities.

Cox actively blocked user infringement and terminated the vast majority of violations, whereas Storm did not intervene despite knowing that Tornado Cash was used by criminals for money laundering.

The outcome of this case is expected to set a significant precedent for the DeFi (Decentralized Finance) sector and the legal responsibilities of software developers. As the proceedings continue in the Southern District of New York, the industry remains focused on how the court will define the boundary between writing code and operating a financial service. Currently, the DOJ remains firm in its position that the technical architecture of the Ethereum-based mixer does not exempt its creators from existing financial regulations.
