The US Department of the Treasury is facing backlash over its claim that a final court ruling on the Tornado Cash lawsuit is moot after delisting the crypto-mixing protocol from its sanctions list.
Coinbase's Chief Legal Officer argues that a final ruling is needed to prevent further attacks on the protocol.
The US Treasury removed Tornado Cash from its Specially Designated Nationals list on March 21, following a court ruling that determined the Treasury had exceeded its authority by sanctioning the protocol.
The Treasury Department's claim of mootness is challenged, with arguments that a final court judgment is necessary to prevent future relisting of the crypto mixer.
