Markwayne Mullin, Secretary, Department of Homeland Security v. Dahlia Doe

The Supreme Court issued a decision in a fight over whether part of the Temporary Protected Status (TPS) law blocks lawsuits under the Administrative Procedure Act (APA) over the Department of Homeland Security's decision to end TPS for people from Syria and Haiti. The materials provided here do not identify the vote or which side prevailed.

A decision was released on June 25, 2026, but the materials provided here do not list the vote count, opinion author, or lineup.

This matters because it affects whether TPS recipients from Syria and Haiti can get a federal judge to review DHS's action. It also tells agencies and lower courts how much court review is available in similar immigration disputes.

Lower courts and DHS must now apply the Supreme Court's instructions in the Syria and Haiti TPS cases. In practice, that means the APA suits will either continue, narrow, or end based on the Court's answers about court review and the challengers' claims.

It addressed whether the TPS statute blocks APA suits over ending TPS for Syria and Haiti, and whether claims succeed if review is allowed.

TPS holders from Syria and Haiti are most directly affected because the decision controls whether they can press these federal court challenges.

Lower courts and DHS must apply the Supreme Court's instructions. The cases will move forward or stop based on the Court's answers about review and the APA claims.
