The federal case over Anthropic's Fable 5 shutdown outlived the shutdown itself, and that gap tells you more about how AI export policy actually works than the ban ever did.
Anthropic's Fable 5 and Mythos 5 models are back online for foreign nationals. The government order that forced them offline is gone. But the company that sued over it, Legion LegalTech Corp, hasn't dropped its case. According to the docket for Legion LegalTech Corp v. United States of America, filed in the U.S. District Court for the District of Columbia and tracked on CourtListener under case number 1:26-cv-02225, a judge ordered the government to respond to Legion's motion for a preliminary injunction by July 14, a deadline that falls after the underlying dispute was supposedly resolved.
Start with what actually happened on June 12. The Commerce Department's Bureau of Industry and Security, under Secretary Howard Lutnick, ordered Anthropic to cut off Fable 5 and Mythos 5 for any foreign national, wherever they were located, including Anthropic's own foreign employees. The stated reason was national security. Anthropic has said the government never gave it specifics, and that the trigger appears to have been another company's claim that it had jailbroken Mythos, a claim Anthropic says it only saw described verbally and that covered a narrow, non-universal workaround.
Here's the part that made the order so blunt. Anthropic has hundreds of millions of users and no reliable way to check someone's nationality in real time at that scale. So it didn't build a filter. It shut both models down globally, for everyone, the same day the order landed.
Legion LegalTech Corp, a San Jose litigation-drafting startup founded in 2024 and run by CEO Arthur Rothrock, builds AI software that helps lawyers draft pleadings and discovery requests, and its own development team works partly out of Canada. When Fable 5 went dark, so did Legion's Canadian engineers. Legion sued on June 23, arguing the order exceeded the government's authority under the Export Control Reform Act, the International Emergency Economic Powers Act, and the Administrative Procedure Act. Its complaint called the harm "immediate, irreparable, and existential" and asked the court both to vacate the directive and to block its enforcement while the case proceeds.
You don't often see a customer, rather than the AI company itself, become the plaintiff in a fight over export policy. Anthropic isn't even a party to the suit. Legion is.
Commerce lifted the export controls on June 30. Anthropic began redeploying Fable 5 and Mythos 5 on July 1, this time with nationality-based access gating built into onboarding and a retrained safety classifier that the company says now blocks the reported jailbreak technique in more than 99% of cases. For most of Legion's engineers, service resumed. For the lawsuit, nothing closed.
That's the detail worth sitting with. The commercial emergency is over. The legal question underneath it, whether the government can use export control law to reach into a hosted AI model's outputs at all, was never actually answered. Legion is still asking a federal judge to say the June 12 order was unlawful, not just reversed.
This didn't come out of nowhere. It's the second major clash between Anthropic and the Trump administration this year. In February, the president directed federal agencies to stop using Anthropic's technology altogether, and Defense Secretary Pete Hegseth designated the company a "supply chain risk," the first time that label had been applied to an American company. The June export order was the second shoe.
For other AI vendors selling into enterprise software, the nationality gating fix is probably the more useful takeaway right now. It shows a way to satisfy an export directive without a blanket shutdown, and it's a cheaper insurance policy than rebuilding trust with customers after a global outage nobody saw coming. But if you run a company whose product depends entirely on continuous access to someone else's model, and you've watched what happened to Legion, the harder lesson is that access restored isn't the same as the underlying authority tested. Legion is still in court asking a judge to settle that question. Its answer is due July 14.
