US Supreme Court to Rule on Trump's Tariffs Today: What's at Stake?

• The US Supreme Court is expected to rule today on the legality of Donald Trump's tariffs imposed on trading partners.
• The court will examine if the administration has authority to impose tariffs under the International Emergency Economic Powers Act (IEEPA) and if importers should be reimbursed.
• Lower courts previously ruled that Trump's executive orders exceeded presidential authority and that tariffs on Mexico, Canada, and China were unlawful.
• If the Supreme Court sides with Trump, it could grant the president broad power to impose taxes; if it rules against him, the administration might face $150 billion in refund demands.
• Experts suggest the Trump administration has alternative legal avenues, like the 1962 Trade Act, to maintain tariffs even if the IEEPA ruling goes against them.

Why It Matters: The US Supreme Court's tariff ruling could redefine presidential power and trigger massive refunds.
