The 6-3 decision in Mullin v. Doe reversed preliminary injunctions that had previously prevented the agency from implementing the terminations.

The Decision

On June 25, 2026, the Supreme Court of the United States issued its decision in Mullin v. Doe, ruling that the Department of Homeland Security has the authority to end Temporary Protected Status for foreign nationals from Haiti and Syria. In a 6-3 decision, the Court reversed preliminary injunctions that had previously prevented the agency from implementing the termination of these protections. The ruling was issued alongside the consolidated companion case, Trump v. Miot.

Why It Matters

The resolution of this dispute clarifies the boundaries of executive power regarding humanitarian immigration relief. By lifting the preliminary injunctions, the Supreme Court affirmed that the Department of Homeland Security holds the administrative authority to withdraw temporary protections previously granted to specific foreign populations.

This outcome represents a substantial victory for executive branch discretion. When lower courts issue preliminary injunctions against federal agencies, they effectively freeze policy implementation while litigation proceeds. The Supreme Court's reversal signals that federal judges should exercise restraint before halting agency determinations concerning foreign nationals. For administrative law practitioners, the ruling demonstrates the high burden plaintiffs face when attempting to block immigration policy changes before a final judgment on the merits. The decision indicates that the executive branch retains broad flexibility to adjust or terminate temporary statuses as foreign policy or domestic priorities shift.

Who Should Care

For lawyers

Appellate litigators and immigration attorneys must carefully analyze the procedural aspects of this 6-3 ruling. A notable element of the decision involves the mechanics of appellate jurisdiction. Justice Alito authored an opinion regarding interim appeals within the case. However, this specific procedural theory failed to gain universal traction among the conservative justices, as Justices Gorsuch and Barrett declined to endorse Justice Alito's theory regarding interim appeals. Litigators should note this fracture, as it suggests ongoing internal debates on the Court regarding the proper handling of interlocutory challenges and interim appellate jurisdiction. Attorneys representing foreign nationals or challenging agency actions will need to adjust their strategies for seeking preliminary relief, recognizing the Court's deference to the Department of Homeland Security.

For consumers and parties

Foreign nationals from Haiti and Syria who currently rely on Temporary Protected Status face direct consequences from this ruling. Because the Supreme Court reversed the orders that were protecting their status, the Department of Homeland Security is now legally cleared to end their ability to live and work in the United States under this program. Employers who hire workers with this specific status must prepare for the administrative reality of their employees losing work authorization. Affected individuals will need to consult with legal counsel to determine if they qualify for other forms of immigration relief, as the temporary protections they previously held are now subject to immediate termination by the agency.

Legal Background

Temporary Protected Status is an immigration benefit that allows foreign nationals to remain in the United States if unsafe conditions—such as armed conflict or natural disasters—prevent their safe return home. The executive branch, acting through the Department of Homeland Security, periodically reviews these designations to determine if the unsafe conditions persist.

When the agency announced its intention to end the status for nationals of Haiti and Syria, affected individuals filed lawsuits to stop the terminations. The plaintiffs successfully secured preliminary injunctions from lower courts. These injunctions served as temporary judicial orders that paused the agency's plans, preserving the status quo while the underlying legal arguments were litigated.

The government appealed these orders, arguing that the judicial branch was improperly interfering with clear executive authority. The dispute ultimately reached the Supreme Court in Mullin v. Doe to resolve whether the lower courts had overstepped by blocking the agency's directives.

What the Court Did

In its 6-3 ruling, the Supreme Court sided with the federal government, concluding that the Department of Homeland Security possesses the authority to end the protected status for foreign nationals of Haiti and Syria. Based on this conclusion, the Court reversed the preliminary injunctions that had kept the terminations from taking effect.

The decision focused heavily on the statutory allocation of power to the executive branch. The majority determined that the agency acted within its legal bounds when it decided to withdraw the protections. While the substantive outcome was clear, the procedural reasoning revealed divisions. Justice Alito authored an opinion addressing the rules governing interim appeals in such administrative disputes. His reasoning on this front, however, did not persuade the entire majority. Justices Gorsuch and Barrett specifically declined to endorse Justice Alito's theory regarding interim appeals, indicating a narrower agreement on the final result rather than a unified consensus on the procedural pathways used to reach it.

How It May Be Applied

The immediate practical effect of the ruling is that the Department of Homeland Security can proceed with its administrative processes to terminate Temporary Protected Status for individuals from Haiti and Syria. The agency will likely issue formal guidance detailing the timeline and procedures for the wind-down of these protections.

Looking forward, federal agencies will likely cite this decision to defend against future requests for preliminary injunctions in immigration disputes. The ruling sets a strong precedent that executive determinations regarding temporary statuses are insulated from early judicial intervention. Furthermore, the disagreement between Justice Alito and Justices Gorsuch and Barrett leaves open questions regarding the precise rules for interim appeals. Appellate courts will have to interpret this fractured reasoning when deciding whether they have jurisdiction to hear early appeals in similar administrative law cases.

Plain-English Summary

When the federal government grants a temporary right to stay in the country, it generally retains the power to take that right away. By reversing the lower court orders, the Supreme Court made it clear that the Department of Homeland Security holds the legal authority to end Temporary Protected Status for people from Haiti and Syria. The lower courts had temporarily blocked the government from ending these programs, but the 6-3 decision removes those roadblocks. This means the agency can now proceed with its plans to terminate the statuses, and affected individuals will need to prepare for the end of their temporary protections.
