According to Odaily, the legal team for Tornado Cash developer Roman Storm has filed a motion arguing that prosecutors were aware since 2023 that FinCEN documents clearly state non-custodial crypto mixers do not constitute a 'money transmission business.' Despite this, a lawsuit was filed, allegedly withholding favorable evidence. The defense has referenced the same documents used in the Samourai Wallet case, urging the court to reconsider dismissing the case. Prosecutors have denied any concealment, asserting that all relevant materials were submitted within the required timeframe.
