The Supreme Court on Friday struck down President Donald Trump’s biggest and boldest tariffs. But the justices left a $133 billion question unanswered: What is going to happen to the money the government has already collected in import taxes that have now been declared unlawful? Companies have been lining up for refunds ahead of the court’s decision. But consumers, hoping for a refund on higher prices they paid when companies passed along the cost of the tariffs, are unlikely to be compensated. And the way forward is unclear and could prove chaotic.
