The Supreme Court's decision has led questions over whether people can get a refund over the unlawful tariffs.

The Supreme Court ruling that President Trump's tariffs are illegal will lead companies to seek billions in refunds, but the decision was silent on the issue.

The administration is also considering Section 122 of the Trade Act, which permits the president to impose a temporary, across-the-board tariff of up to 15 percent to address trade imbalances. Trump has discussed implementing a global tariff of about 10 percent through this authority, NPR reported.
