WASHINGTON — Supreme Court rulings are expected Tuesday as the justices take the bench for a public session that may include decisions in argued cases, Jan. 20, 2026. The court will not say which opinions are coming, but businesses, states and global markets are watching for any word in the fight over President Donald Trump’s sweeping tariffs imposed under emergency powers.
The court’s Supreme Court’s “Today at the Court” schedule says an order list is set for 9:30 a.m., followed by a 10 a.m. session that includes two oral arguments and the possibility of opinions. If the tariff decision is not among the Supreme Court rulings released, it would remain one of the biggest unanswered questions of the term.
A Reuters report about the next opinion day said the justices planned to resume opinion announcements Jan. 20 while the tariff case stays pending. The justices heard arguments in November and have kept the dispute under advisement longer than many other cases argued early in the term.
Supreme Court rulings in the Trump tariffs case
At the center of the tariff showdown are consolidated cases brought by small businesses and a group of states challenging Trump’s use of the International Emergency Economic Powers Act, a 1977 statute typically used to restrict or block foreign economic activity during a declared national emergency. The Supreme Court has posted the case docket and oral-argument audio from Nov. 5, when several justices pressed the administration on whether the law clearly authorizes tariffs.
Supreme Court rulings could either cement Trump’s ability to deploy broad import duties by declaring an emergency — or force the White House back to Congress, where tariff authority traditionally begins. The administration has signaled it is preparing for a loss: a separate Reuters report said U.S. Trade Representative Jamieson Greer told The New York Times the government would “start the next day” to replace the duties using other trade statutes if the Supreme Court strikes the tariffs down.
How the tariff dispute reached the Supreme Court
The fight accelerated soon after Trump unveiled the tariffs in 2025. In April 2025, small businesses and the Liberty Justice Center filed suit in the Court of International Trade seeking to block the duties, Reuters reported at the time. Lower courts later ruled that the president had exceeded his authority under IEEPA, setting up the Supreme Court review.
In September 2025, the justices agreed to decide the legality of the tariffs on an expedited track, as described in another Reuters report. The question echoes earlier fights over presidential tariff power: the Supreme Court declined in June 2019 to hear a constitutional challenge to Trump’s steel tariffs imposed under a separate national-security law, according to Reuters’ coverage.
Whatever comes from the bench, Tuesday’s Supreme Court rulings will be watched well beyond the courthouse, with importers, trading partners and lawmakers weighing how much leverage a president can claim in the name of an economic emergency. If the tariffs decision does not arrive Jan. 20, the justices could still issue it any time in the coming months as the court continues releasing opinions through the end of the term.
