9th Circuit rejects ICE's indefinite detention policy, says Trump admin's 'new power' simply 'does not exist'

The Ninth Circuit Court of Appeals struck down the Trump administration's indefinite detention policy for immigrants, ruling that the government lacks legal authority to hold individuals without time limits.

The court rejected the administration's interpretation of federal immigration law as a dramatic and unauthorized expansion of detention power. In its opinion, the panel stated that Congress would have used clearer language if it intended to grant such expansive authority to Immigration and Customs Enforcement (ICE). The court emphasized that the government's claimed power "simply does not exist" under current statutes.

The ruling addresses a critical issue in immigration enforcement. Under the challenged policy, ICE attempted to detain noncitizens indefinitely beyond standard removal proceedings. The Ninth Circuit found this practice violated statutory constraints on government detention authority. The court's language, calling the administration's interpretation a "dramatic expansion," signals judicial skepticism toward broad executive power in immigration matters.

This decision carries immediate practical consequences. ICE must now comply with congressionally mandated time limits for detention. Immigrants previously held under indefinite detention policies gain protection against prolonged incarceration without resolution of their cases. The ruling also restricts government flexibility in managing immigration enforcement operations.

The Ninth Circuit's approach reflects established administrative law principles. Courts require explicit statutory authorization before allowing agencies to exercise sweeping powers affecting individual liberty. Silence or ambiguity in statutes does not permit agencies to invent new enforcement tools. The court applied this doctrine to conclude that even the broad authority Congress granted immigration agencies has limits.

This decision will likely impact detention practices across the western United States, where the Ninth Circuit holds jurisdiction. Other federal circuits may face similar challenges to detention policies, potentially creating conflicting precedent until the Supreme Court resolves the issue. Immigration advocacy groups celebrated the ruling as protecting due process rights. The administration's response remained unclear at publication.
