Supreme Court Declares Tariffs Unconstitutional The U.S. Supreme Court issued a 6‑3 decision that only Congress may levy taxes, striking down most of President Trump’s emergency‑powers tariffs [1][2]. The justices held the executive‑branch tariffs violated the Constitution, prompting immediate policy revisions. The ruling specifically invalidated the broad import taxes announced earlier this year.

Trump Announces 15% Global Tariff After Ruling President Trump used his social‑media platform on Saturday to declare a worldwide 15% tariff, up from the 10% rate he announced a day earlier [1][2]. The increase is intended to replace the invalidated emergency‑powers tariffs and will apply to all imports unless Congress acts. He scheduled the existing 10% levy to begin on Tuesday, the day of his State of the Union address, for a 150‑day period.

Administration Plans New Legal Mechanism for Higher Tariff Trump said he will rely on a narrower executive order and Commerce Department investigations to justify the 15% rate [1][2]. The White House has not confirmed when a new order raising the tariff to 15% will be signed, though Trump claimed a “thorough, detailed, and complete review” of the Court’s decision [1]. He indicated the higher tariff could be implemented in the coming months under a “legally permissible” authority.

Democrats Criticize and White House Withholds Timing House Ways and Means Committee members labeled the hike “pickpocketing” American consumers, and Governor Gavin Newsom accused Trump of ignoring public welfare [1][2]. Trump launched personal attacks on the justices, praising dissenters Brett Kavanaugh, Thomas and Alito while condemning Gorsuch, Barrett and Chief Justice Roberts [1][2]. Treasury data show $133 billion collected from prior tariffs, but the Court did not address the disposition of those funds.
