A U.S. federal judge on Thursday ruled that the Department of Defense’s decision to place the artificial intelligence company Anthropic on a blacklist was unlawful. According to Reuters, U.S. District Judge Rita F. Lin found multiple legal defects in the Defense Department’s actions.
Constitutional and procedural findings
Judge Lin concluded that the Pentagon’s measures:
- amounted to unlawful retaliation that violated the First Amendment of the U.S. Constitution; and
- deprived Anthropic of the right to due process guaranteed by the Fifth Amendment.
The ruling also determined that Defense Secretary Pete Hegseth’s decision to designate Anthropic as a supply‑chain risk was inconsistent with the applicable statutory framework and therefore was arbitrary and capricious.
Why this matters
The decision is notable because it challenges the government’s use of blacklists or restrictions on companies in the name of supply‑chain security, especially where such actions may implicate constitutional protections and administrative‑law limits. The ruling could affect future government actions that restrict contractors or technology providers on national‑security grounds.
