The big court in America made a choice. It is about a past President. Donald Trump wanted to add taxes.
The court says no. Only the leaders can add taxes. This happened on Friday.
Trump's old money plans are hard now. The court says leaders must agree. This is very important.
Trump said he is not happy. He said taxes will go up. He shared this on the internet.
This choice is big for shops. It makes trade plans less sure. Shops had problems before.
