On Friday, the Supreme Court released a long-awaited decision, ruling that the President’s imposition of tariffs, using the 1977 International Emergency Economic Powers Act, otherwise known as IEEPA, was illegal. The President held a press conference that afternoon and issued a proclamation announcing a general 10% tariff on imported goods, using a different statute and promised to invoke a third set of statutes to replace the overturned tariffs on a more permanent basis. On Saturday, he announced that the 10% tariff rate was being raised to 15%.
