The Supreme Court made a big decision. It stopped former President Donald Trump. He cannot use tariffs too much now. Tariffs are extra taxes on goods.
The court said the president used too much power. This is bad for Mr. Trump's trade plans. The court thinks the president acted like Congress. Congress makes important laws.
The Chief Justice wrote the main part. He said the president needs Congress's okay. This is for big money decisions. The court used a special rule. This rule means Congress must agree clearly.
Businesses and states were not happy. They said the president did too much. Mr. Trump used tariffs a lot. He used them for trade. The court said this was too broad.
The court voted 6-3. This shows courts check the president. Businesses might get money back. This could be billions of dollars. It changes how presidents use tariffs. Mr. Trump wants to use them again. He does not like the court's decision.
