Nah, the Ali Act is Federal Statutory Law, because it was passed by Congress. The only way to overturn it legally is to get Congress to vote to do so -- and there is no where near enough support in Congress. The CSAC was just cheerleading the proposal here, and their vote would have been nothing more than an urge to Congress to consider Dana White's proposal.
The CSAC won't do that anymore IMO, following public backlash.
Dana's only hope now is that the Supreme Court gives Trump unlimited executive power with no limits on his executive orders, beyond stipulating that Congress can vote to overrule any order Trump gives. That would mean Trump could then issue an executive order to gut the Ali Act, so long as Congress didn't actively vote to block him.
