The coalition is asking the court to block the tariffs, declare them unlawful, and order refunds for the duties already paid.
The legal challenge centres on the administration’s effort to preserve Trump’s broad tariff regime after federal courts rejected two earlier versions imposed under different statutory frameworks. The states argue that federal officials seized upon Section 301 of the Trade Act of 1974 and forced-labour concerns merely as a pretext to rapidly recreate nearly identical global duties that the Supreme Court previously struck down in February.
“President Trump’s illegal tariffs are nothing more than a tax on hardworking families, driving up the cost of groceries, household essentials, building materials, and countless everyday goods that New Yorkers rely on,” said New York Governor Kathy Hochul in a statement.
