The Supreme Court issued its decision in Mullin v. Doe on June 25, 2026, resolving whether respondents had standing to challenge the Trump administration's termination of Temporary Protected Status for Syrian nationals — the latest in a series of high-court rulings reshaping the legal landscape for TPS holders from multiple countries.

The Syrian case is one node in a broader docket. The Court had previously issued a ruling in Noem v. National TPS Alliance concerning Venezuela's TPS termination, and a stay application in Trump v. Miot — targeting Haiti's TPS designation — has been pending before the Court since March 2026. Amicus briefs, including one filed on behalf of Haitian TPS holders in case 25-1083, have made clear the Haiti question is closely watched by advocates and affected communities.

TPS, established under the Immigration Act of 1990, grants deportation protection and work authorization to nationals of countries experiencing armed conflict, environmental disasters, or other extraordinary conditions. It currently shields hundreds of thousands of immigrants in the United States, according to Reuters. The Trump administration has moved to terminate the designation for nationals of multiple countries, with DHS terminating Somalia's TPS designation in January 2026 and announcing additional terminations the following month.

The Administration's Legal Position

The administration's posture has been that the executive branch holds nearly unreviewable discretion over TPS designations and terminations. Lower courts ruled against those terminations, with federal judges finding that challengers had standing and that the terminations were subject to Administrative Procedure Act review. The administration argued before the Supreme Court that judges have no role in second-guessing TPS termination decisions — a position grounded in the statutory text granting the Secretary of Homeland Security broad authority over designations.

That framing traces back to the first day of the second Trump term. A January 20, 2025 presidential action directed the federal government to enforce immigration laws as written and to treat prior administrative accommodations as non-binding. TPS terminations followed in sequence across multiple nationalities over the subsequent months.

The DHS announced a legal win on TPS terminations in February 2026, signaling the administration's confidence heading into the Supreme Court term. The Mullin decision and the Court's Venezuela ruling in Noem represent the high court now directly adjudicating those terminations rather than managing them through the stay posture that defined the early phases of litigation.

What the Docket Signals

The Haiti stay application in Trump v. Miot, filed in March 2026 alongside the Ohio Attorney General's amicus brief — the original source document for this report — indicates the Haiti TPS litigation is on a parallel track. The Ohio AG's intervention on the government's side in that proceeding reflects the coalition of state actors the administration has assembled to support its immigration enforcement agenda in the courts.

The cluster of TPS cases — Syria decided, Venezuela ruled on, Haiti still pending — puts the Court in the position of effectively setting the outer bounds of executive discretion over humanitarian immigration programs. The central legal question across these cases is consistent: whether TPS terminations are judicially reviewable and, if so, under what standard. Lower courts applying APA arbitrary-and-capricious review found the terminations wanting. The Supreme Court's resolution of those questions in Mullin and Noem will govern not only the named plaintiffs but every TPS-designated nationality still in litigation.

For practitioners and advocates tracking this docket, the operative question after Mullin is how the Court's reasoning maps onto the Haiti and any remaining country-specific challenges. The standing analysis — whether respondents can bring suit at all — is threshold, and the June 25 ruling on Syria provides the clearest signal yet of where the Court has drawn that line.
