The Supreme Court just struck down Trump's use of emergency powers to impose global, indefinite tariffs (i.e. the tariffs actually have to go through Congress like other taxes, if they're going to be imposed).

-Some specific tariffs, such as those on aluminum and steel, cite other laws for justification and can still be applied.

-The Trump administration previously said they'll attempt other laws as justification if the Supreme Court strikes down their use of emergency powers.
