how did the justices vote on tariffs

The Supreme Court struck down President Trump’s sweeping emergency tariffs in a 6–3 decision, with six justices voting against the tariffs and three voting to uphold them.

How each justice voted

Majority (voted that the tariffs were illegal – against the tariffs)

These six justices formed the majority that ruled Trump lacked authority under the 1977 International Emergency Economic Powers Act (IEEPA) to impose such broad, unilateral tariffs:

  • Chief Justice John Roberts
  • Justice Sonia Sotomayor
  • Justice Elena Kagan
  • Justice Ketanji Brown Jackson
  • Justice Amy Coney Barrett
  • Justice Neil Gorsuch

The majority held that the statute “does not empower the President to levy tariffs” of the scale and breadth Trump claimed, and that he needed clear, explicit authorization from Congress for such extraordinary tariff power.

Dissent (voted to uphold the tariffs – for the tariffs)

  • Justice Clarence Thomas
  • Justice Samuel Alito
  • Justice Brett Kavanaugh

Justice Kavanaugh wrote a dissent arguing that, while the court was limiting Trump’s use of IEEPA, the decision did not necessarily prevent a president from using other trade statutes to impose many of the same types of tariffs under different legal authority.

Why this ruling matters

  • It is a major check on presidential power to use emergency laws to impose wide, long‑running tariffs without Congress explicitly authorizing it.
  • It undercuts a central pillar of Trump’s economic policy, which relied on broad unilateral tariff authority.
  • Even the two Trump‑appointed conservatives Barrett and Gorsuch joined the majority, signaling limits on executive power even from a largely conservative court.

Bottom line: The justices voted 6–3 against Trump’s emergency tariffs, with Roberts, Sotomayor, Kagan, Jackson, Barrett, and Gorsuch in the majority and Thomas, Alito, and Kavanaugh in dissent.
