Breaking News – Supreme Court Affirms Federal Circuit’s Holding in Trump Tariffs Case

This morning the Supreme Court affirmed the Federal Circuit’s holding that the International Emergency Economic Powers Act did not authorize tariffs imposed by President Trump early in his administration. The Court decided the case by a vote of six to three, but it issued splintering opinions totaling 170 pages explaining various approaches to deciding the case. Chief Justice Roberts authored the opinion of the Court, which was joined by Justices Sotomayor, Kagan, Gorsuch, Barrett, and Jackson. In it, Chief Justice Roberts explains why the Court concluded that IEEPA does not authorize the President to impose tariffs. Other parts of the opinion authored by Chief Justice Roberts invoke the major questions doctrine as another basis to affirm the Federal Circuit, but those parts were joined only by Justices Gorsuch and Barrett. Beyond the opinion authored by Chief Justice Roberts, every other Justice except for Justices Sotomayor and Alito issued their own opinions:

  • Justice Gorsuch filed an opinion explaining why he joined in full the opinion of Chief Justice Roberts, paying particular attention to the major questions doctrine.
  • Justice Barrett filed an opinion responding to criticism from Justice Gorsuch about her view of the major questions doctrine.
  • Justice Kagan filed an opinion joined by Justices Sotomayor and Jackson concluding that the Court need not address the major questions doctrine given the Court’s statutory interpretation.
  • Justice Jackson filed an opinion invoking legislative history as another basis to support the Court’s statutory interpretation.
  • Justice Thomas filed an opinion discussing his view that IEEPA is consistent with separation of powers.
  • Justice Kavanaugh filed an opinion joined by Justices Thomas and Alito dissenting from the holding of the Court. This was the primary dissent.

Here are introductions and relevant excerpts of the various opinions.
