What it's about

The Court ruled that the Temporary Protected Status statute prevents courts from hearing nonconstitutional challenges to the Homeland Security Secretary’s decisions to grant, extend, or end TPS, so the government prevailed on the respondents’ Administrative Procedure Act claims. The Court also concluded that the challenge alleging that Haiti’s TPS designation was ended because of race was unlikely to succeed, and it reversed and sent the case back to the lower court.

Question presented

1. Whether the judicial-review bar in the TPS statute, 8 U.S.C. 1254a(b)(5)(A), precludes respondents' APA claims? 2. If reviewable, whether respondents' APA claims nonetheless fail on the merits?

What the Court decided

Holding

The TPS statute bars judicial review of non-constitutional claims. Miot respondents’ equal protection claim is unlikely to succeed. Reversed and remanded.

From the opinions

The Court considered whether a “discriminatory purpose [was] a motivating factor in the decision” to terminate Haiti’s TPS designation.

What's next

Lower courts must apply the Court's decision on remand. Agencies and people affected by TPS decisions will face tighter limits on APA challenges, while constitutional claims remain subject to the Court's analysis.

Why it matters

The decision limits lawsuits using the Administrative Procedure Act (APA), a law governing federal-agency actions, to challenge TPS decisions. For example, people affected by the end of Haiti's TPS designation cannot use non-constitutional APA claims to seek court review.

The case addresses how much power federal courts have to review executive-branch decisions about TPS, a temporary immigration protection for people from designated countries.
