The Supreme Court’s decision to gut President Donald Trump’s ability to impose unlimited tariffs on imports from any country will force him to revert to a traditional set of diplomatic tools that he has largely ignored since returning to power.
The Friday decision, which came after months of speculation on whether the high court would permit him to continue claiming sweeping taxation powers under a 1977 law — the International Emergency Economic Powers Act, which had never before been used for that purpose — struck down nearly every tariff Trump has levied on imports from most American trading partners since returning to the White House last January.
