Legion LegalTech, Corp., a U.S.-based litigation-technology company and a commercial customer of Anthropic with a contractual license to use Anthropic's Fable 5 model, filed this lawsuit in the U.S. District Court for the District of Columbia on June 23, 2026 against the United States of America, US Department of Commerce, Secretary of Commerce, Under Secretary of Commerce, Bureau of Industry and Security, Executive Office of the President, and individual defendants.
Legion filed this lawsuit in response to a June 12, 2026 directive from the Bureau of Industry and Security (BIS), an agency within the Department of Commerce (DOC). BIS sent Anthropic a letter directing Anthropic to suspend access to its Fable 5 and Mythos 5 artificial-intelligence models for “any foreign national, whether inside or outside the United States, including foreign-national Anthropic employees,” under threat of criminal and civil penalties. The government justified the suspension by pointing to a "jailbreak" that let the model review third-party software code and identify flaws, a capability it characterized as a national security threat.
Legion claims the BIS directive misconstrues ECRA and EAR. Legion alleges that to the extent the directive rests on the International Emergency Economic Powers Act (IEEPA), the directive violates IEEPA’s §1702(b)(3) exclusion of informational materials from presidential authority, was issued without the national-emergency declaration required by §1701(a), and claims authority of vast economic and political significance that IEEPA does not clearly confer. Legion further alleges the directive is arbitrary and capricious under the § 706(2)(A) of the Administrative Procedures Act (APA).
Legion seeks a declaratory judgment that the directive is unlawful and void, vacatur, preliminary and permanent injunctive relief, and a stay of the directive.
