India, Feb. 20 -- The Supreme Court on Friday struck down President Donald Trump's global tariffs. The justice, in a 6-3 ruling authored by conservative Chief Justice John Roberts, focused on tariffs imposed under an emergency power, including the sweeping "reciprocal" tariffs announced by the Trump administration of almost every country.

The US Supreme Court ruled that the Trump administration's interpretation that the International Emergency Economic Powers Act (IEEPA) law grants the US President power to impose tariffs would intrude on Congress's authority and violate a legal principle called the "major questions" doctrine.
