President Trump announced Saturday he will raise his newly imposed global tariff to 15%, one day after the Supreme Court ruled 6-3 that he had exceeded his authority under the International Emergency Economic Powers Act of 1977 to impose sweeping import taxes on international trading partners.
The move shifts the legal foundation for tariffs from IEEPA to Section 122 of the Trade Act of 1974, which allows the president to impose tariffs of up to 15% for a maximum of 150 days to address trade deficits. Trump had announced 10% global tariffs on Friday before pivoting to the higher rate and the new statutory authority on Saturday.
Writing on Truth Social, Trump framed the increase as a deliberate response to the Court's ruling:
"Based on a thorough, detailed, and complete review of the ridiculous, poorly written, and extraordinarily anti-American decision on Tariffs issued yesterday, after MANY months of contemplation, by the United States Supreme Court."
He added that in the coming months, the administration would "determine and issue the new and legally permissible Tariffs" to continue what he called an "extraordinarily successful process" of revitalizing the American economy.
The Supreme Court's 6-3 decision struck down Trump's use of IEEPA to impose tariffs aimed at addressing trade imbalances and halting fentanyl smuggling, The Post reports. The ruling forced the administration to find an alternative statutory ground, and it found one quickly.
Section 122 of the Trade Act of 1974 caps tariffs at 15% and limits their duration to 150 days. That ceiling explains the jump from 10% to 15%: if you're working within a tighter legal box, you max it out.
Andrew Hale, a trade expert at the think tank Advancing American Freedom, founded by former Vice President Mike Pence, argued the president is "already on shaky ground" with this approach. Hale contended the law only applies when there are "large and serious US balance of payments deficits under a fixed rate system," and noted that the world "abandoned the fixed rate exchange rate system in the 1970s."
That's a legal argument that will certainly be tested. But the administration is not relying on Section 122 alone.
US Trade Representative Jamieson Greer, the country's chief negotiator on trade, made clear Friday that the tariff agenda extends well beyond a single legal mechanism. Greer said additional tariff efforts under Section 301, "which are incredibly legally durable," would commence immediately.
"We're going to keep continuity in the program."
That matters. Section 301 authority is what Trump used during his first term to impose tariffs on Chinese exports, and those tariffs withstood legal challenges. The process takes more time and requires official investigations before tariffs take effect, but it produces tariffs that stick.
Trump confirmed as much Friday, saying he was "initiating several Section 301 and other investigations to protect our country from unfair trading practices of other countries and companies."
So the picture that emerges is layered:
The 150-day window on Section 122 isn't a vulnerability. It's a bridge. The administration is using it to maintain pressure while constructing tariffs through channels the courts have already validated.
Democrats and the media predictably treated the Supreme Court decision as a definitive blow to the tariff agenda. They are making the same mistake they always make: confusing a procedural setback with a policy defeat.
Trump didn't abandon tariffs after the ruling. He raised them. Within 24 hours. The administration didn't pause, regroup, or issue a somber statement about respecting judicial review. It found another statute and went bigger.
Sen. John Kennedy (R-La.) offered the sharpest political read of the moment on Fox News:
"My Democratic peeps better be careful what they ask for. Because if he gives back $300 billion worth of tariff money to the business community in America, this economy's going to roar, man, and the midterms are only a few months off."
Kennedy's point cuts to the core of the left's problem. They celebrated the Court ruling as a win, but the ruling doesn't eliminate tariffs. It redirects them through different legal channels. And if the transition period produces even modest economic gains, Democrats will have handed the administration a narrative gift heading into the midterms.
Trump previously said he was "ashamed" of the three conservative justices who ruled against him. That frustration is real, but the response was not paralysis. It was an adaptation.
The next few months will determine whether the Section 122 authority survives its own inevitable legal challenge. Hale's argument about the fixed exchange rate system is the kind of textual objection that will land on a federal judge's desk within weeks. The administration clearly believes it can defend the authority long enough for Section 301 investigations to produce permanent, battle-tested tariffs.
The broader question is whether the courts will allow any president to use trade law for its stated purpose: protecting American workers and industries from imbalanced foreign competition. The Supreme Court said IEEPA wasn't the right tool. The administration says fine, here are others.
The tariff agenda didn't die on Friday. It changed vehicles.
