Supreme Court Questions Trump's Tariff Authority, Alternative Options Remain
The highest court in the US heard arguments about whether President Trump had the right to put extra taxes, called tariffs, on goods from almost every country using a special emergency law.
Some judges seemed unsure if this law really lets the President do something as big as imposing taxes, as usually only Congress can decide on taxes.
The President's lawyers say these tariffs are needed because of emergencies and that he has the power to do this.
If the judges say the President can't use this specific emergency law for tariffs, it might mean companies that paid them could get their money back.
However, even if this one law is ruled invalid, experts say President Trump has other laws he can use to still put taxes on imported goods, so tariffs might continue.
The Supreme Court heard arguments questioning President Trump's authority to impose global tariffs under the International Emergency Economic Powers Act (IEEPA).
Justices expressed skepticism and deep concerns regarding the use of IEEPA for broad tariff impositions, suggesting it may exceed presidential powers and noting it has never been used for this purpose.
If the Supreme Court strikes down the IEEPA tariffs, businesses that paid them may be entitled to refunds, with approximately $90 billion collected in revenue.
Experts suggest that even if the court overturns the current tariffs, President Trump has several other statutory authorities available to impose similar duties.
Alternative authorities mentioned include Section 301, Section 232 of the Trade Expansion Act, and provisions within the Tariff Act of 1930, which have varying conditions and historical contexts.

Use of International Emergency Economic Powers Act (IEEPA)
Arguments Against Trump's Tariff Authority
Supreme Court justices, led by Chief Justice John Roberts, expressed deep concerns and skepticism regarding the Trump administration's use of the IEEPA to impose global tariffs, noting it has never been used for such purposes and questioning if it exceeds presidential authority for broad tariff imposition.
Arguments Supporting Trump's Tariff Authority and Alternative Options
The administration, represented by US Solicitor General D John Sauer, argued that the IEEPA statement includes the power to impose tariffs, making its use applicable. Experts also note that even if the court overturns tariffs imposed under IEEPA, President Trump has numerous other statutory authorities to implement similar duties.
Scope of Presidential Power vs. Congressional Authority
Arguments Against Trump's Tariff Authority
Justices questioned the administration's assertion of power to impose tariffs on any product, from any country, in any amount, and for any length of time, suggesting this broad claim might be a 'misfit' for the law. The US Constitution generally grants Congress the power to tax.
Arguments Supporting Trump's Tariff Authority and Alternative Options
While the court's decision is pending, the administration warns that overturning the tariffs could leave the US 'defenseless.' The existence of alternative presidential powers, such as Sections 301 and 232, suggests that trade policy could continue to be shaped by the executive branch.
Potential Consequences of Overturned Tariffs
Arguments Against Trump's Tariff Authority
If the tariffs are struck down, businesses that paid them may be entitled to refunds, potentially involving complex processing and significant financial implications for the Treasury, as approximately $90 billion in revenue has been collected. Consumers might also have grounds to sue businesses for passing on unlawful tariff costs.
Arguments Supporting Trump's Tariff Authority and Alternative Options
If tariffs are overturned, consumers could benefit from lower prices on imported goods, potentially saving households money. However, Trump has claimed the US would be left 'defenseless' and reduced to 'Third World status' if tariffs are removed.
