# Dual-court split on AI governance enforcement creates legal uncertainty during capability deployment because district courts block on constitutional grounds while appellate courts allow on national security grounds

The Anthropic supply chain designation litigation produced contradictory results across two court levels within two weeks. On March 24-26, District Judge Rita Lin issued a preliminary injunction blocking both the DoD supply chain risk designation and Trump's executive order banning federal use of Anthropic technology, finding the designation was likely unconstitutional retaliation for First Amendment-protected speech. On April 8, the DC Circuit denied Anthropic's emergency bid for relief in what appears to be a separate or parallel appellate proceeding, with the 'active military conflict' rationale explicitly invoked. This creates a governance uncertainty pattern where: (a) the district court injunction may still be in effect for some purposes (executive order ban on federal use), (b) the DC Circuit denial may apply to different relief requests (stay of the supply chain label itself), or (c) the DC Circuit ruling supersedes the district court entirely. The procedural complexity means the legal status of the designation remained contested through May 19 oral arguments. This dual-court split reveals that AI governance enforcement during capability deployment faces genuine judicial contestation—not a slam-dunk for DoD authority. The First Amendment retaliation framing proved persuasive at trial court level while national security deference prevailed at appellate level, suggesting the legal question turns on which frame dominates rather than clear statutory authority.
