A.A.R.P. v. Trump

Background

The case involves people held in federal custody and the Government, including the President. The detainees’ lawyers filed a petition challenging their detention and asked a federal court in Texas to treat the matter as a class action for 'all noncitizens in custody in the Northern District of Texas' who were or would be subject to a March 2025 Presidential proclamation invoking the Alien Enemies Act. They warned of imminent deportation and sought an emergency temporary order to stop removals. After the district court did not rule within a tight deadline, the applicants appealed.

Reasoning

The central question was whether this Court should issue emergency relief under the All Writs Act to stop removals while appeals proceed. Justice Alito explains why he thinks the Court should not have acted: he says the All Writs Act does not create independent jurisdiction, the appeal may not have been properly before the courts because a true temporary order was not denied, the applicants may have failed to seek full relief first in the district court, and the Court issued relief without hearing the Government’s views or waiting for the appeals court. He also notes the district court had not certified a class and that seeking classwide relief in a detention challenge raises legal doubts.

Real world impact

The order temporarily prevents the Government from removing the covered detainees while the Supreme Court considers the matter, so any planned deportations would be paused. Because this is an emergency order and not a final decision, the pause may be short‑lived and could change on further briefing or rulings. The dispute raises practical questions about when and how courts may grant emergency, classwide relief in detention and immigration contexts.

Dissents or concurrances

Justice Alito, joined by Justice Thomas, dissented from the Court’s emergency order, saying the midnight action was premature, procedurally flawed, and lacked adequate factual and adversarial development.
