The Supreme Court dealt a major blow to President Donald Trump’s economic agenda, ruling that he does not have the authority to impose sweeping tariffs at the stroke of a pen.

The court on Feb. 20 tossed the tariffs that are the centerpiece of his economic policy and a major foreign policy tool – but that have also raised costs for consumers and businesses. The 6-3 decision from the conservative court was its first major ruling against Trump’s controversial expansive view of presidential power.
