The Supreme Court's decision Friday to strike down the majority of tariffs imposed by President Trump could provide some relief to L.A.'s trade-reliant economy — but only if they are not reimposed again through other means.

The statute says a president can impose duties to deal with “large and serious” balance-of-payments deficits — an issue related to trade deficits, which some of the president’s IEEPA tariffs purport to address. But it also imposes a 150-day limit on the tariffs, unless Congress votes to extend them.

Trade experts note that businesses seeking tariff refunds may need to appeal to CBP or the Court of International Trade to get their money back after the Supreme Court's ruling.
