Kentucky, Nebraska and 16 Other States & DEF v SEC

Who This Affects: Cryptocurrency users, protocol developers, and front-end providers.

Impact: Eighteen U.S. states, led by Kentucky Attorney General Russell Coleman, along with the DEF, have filed a lawsuit against the SEC and its Chair, Gary Gensler, alleging unconstitutional overreach in the regulation of digital assets. The plaintiffs argue that the SEC’s enforcement actions encroach upon states’ rights to develop and enforce their own tailored digital asset regulations, thereby stifling innovation and displacing state laws designed to protect consumers in the digital asset industry.

What Is DEF’s Argument: DEF, along with the 18 US States co-plaintiffs, argues that the SEC’s enforcement actions represent an overreach of federal authority, undermining states’ rights to establish tailored regulatory frameworks for digital assets. DEF contends that the SEC’s approach stifles innovation, disrupts the development of state-level protections for consumers, and creates uncertainty in the digital asset ecosystem.

Result: Ongoing
