US To Refund Billions? What Next After Supreme Court Strikes Down Trump Tariffs

In a 6-3 verdict, the US court held that the International Emergency Economic Powers Act (IEEPA) does not empower the president to unilaterally impose broad tariffs.

The US Supreme Court delivered a major blow to President Donald Trump, ruling that his administration’s sweeping global tariffs were imposed without lawful authority, a decision that could expose the US government to tens of billions of dollars in refunds.

In a 6-3 verdict, the top court held that the International Emergency Economic Powers Act (IEEPA) does not empower the president to unilaterally impose broad tariffs.

The law, enacted in 1977, allows the executive to regulate certain international economic transactions during a national emergency but does not extend to blanket tariff measures, the court said.

Justices Clarence Thomas, Samuel Alito, and Brett Kavanaugh dissented.

Writing for the majority, Chief Justice John Roberts said Congress has historically delegated tariff powers only in “explicit terms and subject to strict limits."

Allowing the president to invoke IEEPA to impose tariffs at will, he warned, would amount to a “transformative expansion" of executive authority.

“The United States, after all, is not at war with every nation in the world," Roberts noted, underscoring the court’s rejection of the administration’s national emergency justification.

What Happens Now

With the court ruling that the tariffs were imposed unlawfully, they would lose legal force.

US Customs and Border Protection would be required to stop collecting the duties, while enforcement actions tied to those tariffs could be suspended or dropped altogether.

The bigger question now is refunds. US companies that paid billions of dollars in duties could seek rebates for tariffs already collected.

Estimates suggest that more than $175 billion in tariff revenue could potentially be subject to refund claims.

US Treasury Secretary Scott Bessent has said the Treasury Department would be in a position to cover refunds if required, though the Supreme Court itself cautioned that the process could be complex.

“The refund process is likely going to be a mess," the court observed.

Economic Impact

As the struck-down tariffs are removed, import costs are expected to decline for a wide range of goods, including steel, aluminium, electronics, machinery and consumer products.

While some businesses may pass on the savings to consumers through lower prices, economists note that this is not guaranteed.

The rollback could also help stabilise supply chains that were disrupted by years of tariff barriers, potentially restoring trade flows and easing costs for manufacturers and retailers.
