During Supreme Court arguments, justices signaled skepticism toward President Donald Trump’s sweeping claim that emergency powers let him levy tariffs almost at will. Trump warned the nation could be left defenseless if the court overturns his “reciprocal” tariffs on nearly every country, which have lifted the average U.S. rate to 17.9% from 2.5%, according to Yale’s Budget Lab. Yet experts say he could still tax imports using other statutes, including Sections 301, 232, 122 and a Depression-era Section 338, though some require investigations and could prove cumbersome for many countries.
