25 Democrat-led states sue Trump over new tariffs, calling them illegal end run around Supreme Court

Twenty-five states, led by New York Attorney General Letitia James, have filed suit against the administration over the latest round of Section 301 tariffs. The legal theory is straightforward: the White House lost at the Supreme Court on its earlier tariff authority, so it has repackaged the same import taxes under a new statutory rationale and dared the courts to catch up.

The new justification is forced labor. The administration ordered the U.S. Trade Representative to investigate 60 trading partners, found that 59 countries and the European Union were not doing enough to block goods produced by forced labor, and then invoked Section 301 of the Trade Act of 1974. That statute grants the president broad power to retaliate against unfair trade practices, and it has survived legal challenges before.

The states argue this is an end run. If the Supreme Court already struck down the previous tariff regime, they say, the administration cannot simply relabel the same economic weapon and expect it to pass constitutional muster. The White House counters that Section 301 is a durable, lawful tool and that foreign countries' failure to enforce forced labor prohibitions burdens U.S. commerce.

What matters here is not the rhetoric but the sequence. The administration lost one legal battle, found a new statutory hook, and moved forward. The states are now forcing a second judicial test of the same underlying question: how much tariff authority does the executive actually hold? The answer will determine not just the fate of these particular duties, but the durability of the entire trade policy playbook.

For businesses, the practical takeaway is that tariff policy has become a legal battleground with a long fuse. The duties are in effect now, and they will remain in effect while the litigation winds through the courts. Companies that import from the affected countries should assume the current cost structure is the baseline, not a temporary disruption. The only certainty is that the uncertainty will persist until the judiciary issues a definitive ruling.
