WASHINGTON, June 23 - A U.S.-based legal technology company has launched a federal lawsuit challenging a government directive that led to the artificial intelligence developer Anthropic suspending foreign access to two of its most advanced models.
Legion LegalTech Corp filed the complaint on Tuesday in the U.S. District Court in Washington, D.C., seeking to overturn a June 12 order issued by the U.S. Commerce Department's Bureau of Industry and Security. The company says the directive unlawfully required Anthropic to disable its Fable 5 and Mythos 5 models for "any foreign national." According to the suit, Anthropic ceased access for all customers on the same day to ensure compliance with the government order.
San Jose, California-based Legion told the court that it relies on Anthropic's tools to power its software platform, which provides drafting and case-management functionality for attorneys. The company says the government's action immediately cut off members of its Canada-based software development team, disrupting its operations and threatening its business.
In its filing, Legion argued the effect is swift and severe: "The harm to Legion is immediate, irreparable, and existential," the complaint stated. The company added that the rapid pace of frontier AI development means competitive ground lost during a suspension cannot be recovered later, and it urged the court to act.
Legion has asked a federal judge to vacate and set aside the administration's directive aimed at Anthropic. The filing also requests a preliminary order barring the administration from enforcing the directive while the litigation proceeds.
The Commerce Department and the White House did not immediately respond to requests for comment. Anthropic itself is not a named plaintiff in this case. The company referred reporters to a prior statement in which it said it was "grateful to the administration for their ongoing partnership in working to get this matter resolved as quickly as possible."
Separately, Anthropic and the U.S. government are engaged in multiple legal disputes in federal courts in Washington and California. Anthropic previously sued the Trump administration after the government sought to add the company to a supply-chain blacklist. That government action followed Anthropic's refusal to permit the military to use its AI models for domestic surveillance or to enable fully autonomous weapons.
The legal challenge from Legion arrives amid immediate operational impacts on at least one customer and amid broader litigation involving Anthropic and federal authorities. Legion portrays the Commerce Department's order as an unlawful command that cut off a critical service for its international staff and fractured its development workflow.
The case centers on the enforcement of an export-control style order that the Commerce Department issued on June 12, the alleged requirement to restrict access to Fable 5 and Mythos 5 for non-U.S. nationals, and the steps Anthropic took the same day to comply. Legion seeks judicial relief to restore access and to prevent enforcement of the directive while the dispute is resolved.
In court filings, Legion emphasized the immediate business impact and the risk to its competitive position during any suspension of access. The company is pursuing expedited relief through a preliminary injunction while its broader claims are adjudicated.
Anthropic's legal fights with the U.S. government continue in parallel, and the company's relationship with federal officials was referenced in the response Anthropic provided about ongoing engagement to resolve the issue quickly. The Commerce Department action and subsequent litigation reflect a series of disputes over the limits on the use and distribution of advanced AI models.
Investment-oriented commentary in the original coverage also noted market interest in Anthropic-related securities. One such investor tool, ProPicks AI, was mentioned as evaluating ANTP alongside many other firms, saying the system uses more than 100 financial metrics to assess fundamentals, momentum, and valuation. That commentary noted past winners identified by the tool, including Super Micro Computer (+185%) and AppLovin (+157%).
Legal and market implications - summary
The suit by Legion challenges a federal order that interrupted access to advanced AI models and precipitated commercial disruption for at least one customer. It seeks to have the directive vacated and to block enforcement while litigation proceeds.
