Supreme Court blocks IEEPA tariffs in 6-3 ruling, but Trump pivots to other trade authorities

The Supreme Court ruled 6-3 on Friday that the International Emergency Economic Powers Act does not authorize the president to impose import tariffs, striking down the tariffs at issue in Learning Resources, Inc. v. Trump. Chief Justice John Roberts wrote the majority opinion.

President Trump wasted no time. Within hours, he posted on Truth Social calling the decision "deeply disappointing" and announcing an immediate pivot to alternative statutory authorities that the Court's ruling left untouched.

"Today I will sign an Order to impose a 10% GLOBAL TARIFF, under Section 122, over and above our normal TARIFFS already being charged, and we are also initiating several Section 301 and other Investigations to protect our Country from unfair Trading practices."

The decision closes one door. The president is already walking through several others.

What the Court Actually Said

The Roberts opinion held, narrowly, that IEEPA does not grant tariff authority. That matters. But what matters just as much is what the Court did not say. It did not rule that the president lacks tariff authority altogether. It did not touch the half-dozen other federal statutes that have authorized presidential trade action for decades.

Justice Brett Kavanaugh, writing the principal dissent, made that point explicitly:

"Although I firmly disagree with the court's holding today, the decision might not substantially constrain a president's ability to order tariffs going forward."

Kavanaugh then spelled out the reason:

"That is because numerous other federal statutes authorize the President to impose tariffs and might justify most (if not all) of the tariffs issued in this case."

Read that again. The dissenting justice is telling you, in plain English, that the majority's victory may be largely symbolic. The legal architecture for presidential tariff authority is broad, old, and bipartisan in origin. The Court struck down one vehicle. The garage is full of others, as Just The News reports.

The Statutes That Still Stand

Kavanaugh's dissent cataloged the alternatives, and they are not obscure provisions gathering dust in some forgotten corner of the U.S. Code. They are pillars of American trade law spanning nearly a century:

• Section 232 of the Trade Expansion Act of 1962, signed into law by President John F. Kennedy. In 2020, the Supreme Court declined to review a challenge to tariffs imposed under this authority, allowing them to stand.
• Sections 122, 201, and 301 of the Trade Act of 1974, signed by President Gerald Ford. Section 122 permits tariffs of up to 15% for 150 days. Section 301, notably, is the authority Trump is now invoking for new investigations.
• Section 338 of the Tariff Act of 1930, the Smoot-Hawley Tariff Act signed by President Herbert Hoover, which allows discriminatory tariffs of up to 50%.

These are not legal novelties. They are statutes signed by presidents of both parties, tested over generations, and in some cases already upheld or left undisturbed by the courts. Trump's pivot to Section 122 and Section 301 is not improvisation. It is execution under existing law.

The Real Fight

The political class will frame Friday's ruling as a rebuke. Cable news will run the "Supreme Court strikes down tariffs" chyron on a loop. What they will not do is explain the rest of the story: that the president thanked Justices Kavanaugh, Clarence Thomas, and Samuel Alito for their dissents, accused members of the majority of acting for political reasons, and announced concrete next steps before the ink on the opinion was dry.

This is a president who reads a setback as a routing problem, not a stop sign. The 10% global tariff under Section 122 is already in motion. The Section 301 investigations signal a longer-term strategy aimed at countries engaged in what the administration views as unfair trading practices.

The legal question was never really whether a president can impose tariffs. Congress has delegated that power repeatedly since 1930. The question was whether IEEPA was the right statute. Six justices said no. The other tools remain on the table, right where Congress left them.

What Comes Next

Expect the next round of legal challenges to arrive quickly. Opponents of the tariff agenda will test Section 122's 150-day limit, probe the scope of Section 301 investigations, and argue that the spirit of Friday's decision should constrain executive trade power broadly. Those arguments will be harder to win. Section 232 already survived a trip to the Supreme Court's doorstep in 2020. Section 301 has been used by administrations of both parties for decades.

The more interesting question is political. Friday's ruling gives congressional opponents and corporate interests a headline. It does not give them a policy victory. If the 10% global tariff takes effect under Section 122, the economic reality for importers is the same regardless of which statute authorized it.

The Court closed a door. The president opened three more. The trade agenda moves forward on different legal ground, but it moves forward.
