Coinbase's lawyers have responded to the U.S. Securities and Exchange Commission's (SEC) attempt to strike the company's defenses in a civil case. The lawyers argue that Coinbase's defenses are grounded in both fact and law, citing the recent Supreme Court case Biden v. Nebraska. The defenses stem from the SEC's lack of authority to regulate digital asset trading platforms and its unjust conduct in reversing course. The lawyers also argue that the SEC's delay in bringing an enforcement action causes prejudice to Coinbase and its stockholders.
