U.S. prosecutors have rejected Roman Storm’s latest attempt to dismiss criminal charges, setting up a high-stakes retrial battle centered on a pivotal question: can a Supreme Court ruling on internet platforms shield a crypto developer from liability?

Supreme Court argument becomes Storm’s last line of defense

At the heart of the legal clash is Storm’s attempt to leverage on the Cox case which resulted in the U.S. Supreme Court ruling in favour of the platforms stating that companies should be held liable for user misconduct.

Storm’s legal team argues that the Cox case could be the breakthrough that might give them the victory. In Cox, the Court ruled that an internet service provider could not be held liable simply for being aware that some users engaged in illegal activity.

For Storm, the parallel is uncanny. As co-founder of Tornado Cash, he maintains that he has no control over the back actors that might leverage on his platform to engage in illegal activities and transactions. Roman Storm's lawyers added that awareness does not equal intent.

They further pointed out that the U.S. government itself supported Cox’s defense in that case, thus the same justice should be also given to the defendent. Prosecutors, however, have firmly rejected that argument, calling it irrelevant to Storm’s case.

In a sharply worded filing, U.S. Attorney Jay Clayton argued that the comparison to Cox “bears no resemblance” to Storm’s conduct. Unlike the internet provider, prosecutors claim, Storm was aware of illicit use of Tornado Cash and failed to take meaningful steps to prevent it.

They also emphasized a key distinction: Cox actively implemented policies to curb copyright violations, while Storm allegedly did not introduce effective anti-money-laundering safeguards.

Prosecutors went even further, claiming that crypto privacy services like Tornado Cash were just the perfect breeding ground for criminal activities.

That assertion strikes at the core of crypto privacy arguments and is likely to spark backlash from industry advocates who view financial privacy as a fundamental right.

Split verdict sets the stage for a high-stakes retrial

The legal battle follows a dramatic 2025 trial that left Storm in limbo. A jury convicted him of operating an unlicensed money-transmitting business but failed to reach a verdict on more serious charges, including money laundering conspiracy and sanctions violations.

Those unresolved charges—carrying potential decades in prison—are now headed toward a possible retrial, with prosecutors pushing for proceedings as early as October.

Storm has framed the case as a defining moment for developers, arguing he faces severe penalties for writing open-source code tied to a protocol he does not control.

Complicating matters further is the shifting stance of the Justice Department under Todd Blanche. Blanche has previously criticized “regulation by prosecution” and signaled that authorities should avoid targeting platforms for how users behave.

Yet the continued push to retry Storm appears to contradict that position, raising questions about whether U.S. crypto enforcement policy is evolving or simply inconsistent.

A defining test for code, liability, and crypto’s future

As the retrial looms, the case has evolved into more than a single prosecution. It is now a referendum on the legal boundaries of decentralized technology.

If Storm’s interpretation of Cox holds, it could establish a powerful precedent protecting developers from liability tied to user behavior. If prosecutors prevail, it may reinforce the idea that writing code is not neutral when it enables illicit finance at scale.

Either way, the outcome will shape how courts—and the crypto industry—define responsibility in an era where software, not institutions, powers financial systems.
