Bittrex is seeking to dismiss SEC charges alleging that the now-shuttered exchange listed unregistered securities on its platform. 

“The SEC lacks the ‘clear congressional authorization’ required to apply the securities laws to tokens,” Bittrex argued. 

“The Commission is still missing essential elements of its claims. And those claims exceed its authority and defy key securities-laws precedents. This is inexcusable. When the government brings an enforcement action, especially after a prolonged investigation, it should adhere rigorously to the pleading standards and relevant statutory constraints. The SEC failed to do so here,” Bittrex said in its filing.
