B Mirror Report: The announcement came hours after the Supreme Court, in a 6-3 decision, ruled that the president lacked authority to impose sweeping tariffs under a 1977 economic emergency powers law. Immediately after the verdict, Trump had unveiled a 10 percent global levy using a separate legal mechanism.

The president also launched a sharp attack on conservative justices who joined the majority opinion, accusing them of “disloyalty” and branding them “fools and lap dogs.”

The ruling marked a rare setback for Trump at a court that has often sided with him since his return to office 13 months ago. It struck at the heart of his signature trade strategy, which has disrupted global markets and reshaped international commerce.

Saturday’s move is expected to fuel fresh uncertainty as Trump continues a trade campaign that has alternately pressured and penalized allies and rivals alike. Over the past year, tariff rates on countries exporting to the United States have frequently been introduced, revised, or withdrawn by the administration.

Under US law, the newly announced 15 percent tariff can remain in place for up to 150 days. A White House fact sheet said exemptions would continue for sectors subject to separate investigations, including pharmaceuticals, as well as goods covered under the US-Mexico-Canada Agreement. Countries that negotiated individual tariff arrangements with Washington would also be subject to the new global rate.

Friday’s ruling does not affect sector-specific tariffs already imposed on steel, aluminum, and other products. Ongoing government investigations could result in further targeted duties.

Trump praised the three conservative justices who voted in favor of preserving his tariff authority Clarence Thomas, Samuel Alito and Brett Kavanaugh  thanking them for their “strength and wisdom.” He alleged that the majority, including two justices appointed during his first term, had been influenced by “foreign interests.”

Financial markets reacted cautiously, with Wall Street stocks edging higher after the long-anticipated decision. Business groups welcomed the ruling, with the National Retail Federation saying it offered “much-needed certainty” for companies.

During court proceedings, administration lawyers argued that companies would be reimbursed if the tariffs were found unlawful. However, the Supreme Court did not address the refund issue. Trump predicted prolonged litigation over potential repayments, while Justice Kavanaugh acknowledged the process could become a “mess.”

Several countries said they were reviewing both the court’s decision and Washington’s latest tariff steps. German Chancellor Friedrich Merz announced plans to consult European partners to craft “a very clear European position” ahead of a visit to Washington in early March.

At home, Pennsylvania Governor Josh Shapiro urged the president to “listen to the Supreme Court, end chaotic tariffs, and stop wreaking havoc on our farmers, small business owners, and families.”
