Stocks weakened amid ongoing uncertainty, with the **Nasdaq Composite** down 0.9% and the S&P 500 down 0.5%. The **Dow Jones Industrial Average** also moved lower, slipping by 0.2%.\n\nThe case represents a significant test of presidential authority, with justices widely expected to rule against the way Mr Trump’s so-called “liberation day” tariffs were implemented. The former president relied on the **International Emergency Economic Powers Act** to introduce what he described as “reciprocal” tariffs on imports from a range of countries in April last year.\n\nMr Trump had previously invoked the same legislation to impose tariffs on **China**, **Canada** and **Mexico**, citing a national emergency linked to drug trafficking into the United States.\n\nThe Supreme Court is scheduled to release its latest rulings on Tuesday or Wednesday next week, although it does not indicate in advance which cases will be addressed. Markets had been alert to the possibility of an update on tariffs on Friday, but no decision was issued at that time."}
