California sues at N.D. Cal. to block IEEPA tariffs

On 16 April 2025 the State of California, through Attorney General Rob Bonta and Governor Gavin Newsom, filed State of California v. Trump, No. 3:25-cv-03372, in the U.S. District Court for the Northern District of California, challenging Executive Orders 14193, 14194 and 14195 (1 February 2025; trafficking emergencies as to Canada, Mexico and China), their amending orders (14197, 14198, 14226, 14228, 14232, 14256), Executive Order 14257 (2 April 2025; reciprocal-tariff emergency), Executive Order 14259 (8 April 2025; China rate to 84 per cent) and Executive Order 14266 (9 April 2025; China rate to 125 per cent).¹ Bonta said in a 16 April press conference: “The President’s chaotic and haphazard implementation of tariffs is not only deeply troubling, it’s illegal.”² Named defendants include President Trump, Secretary of Homeland Security Kristi Noem, U.S. Customs and Border Protection, Acting CBP Commissioner Pete R. Flores and the Department of Homeland Security; the complaint also names the Secretary of Commerce, the USTR and the Secretary of the Treasury.³ The complaint seeks a declaratory judgment that the tariffs are unlawful and a permanent injunction barring their enforcement.¹

1. The State asserts sovereign, parens patriae and proprietary standing. Under Massachusetts v. EPA, 549 U.S. 497, 518-20 (2007), states are accorded “special solicitude” in standing analysis when they assert quasi-sovereign interests on behalf of their residents.⁴ The challenged orders invoke the International Emergency Economic Powers Act, 50 U.S.C. § 1702(a)(1)(B); the National Emergencies Act, 50 U.S.C. § 1601 et seq.; § 604 of the Trade Act of 1974, 19 U.S.C. § 2483; and 3 U.S.C. § 301.⁵⁶

2. The complaint pleads California-specific economic and fiscal harms: pass-through cost increases to California consumers and producers, reduced state tax receipts tied to retail and business activity, and impairment of contracts of California-domiciled importers — distinct from the importer- standing theory in V.O.S. Selections, Inc. v. Trump, No. 1:25-cv-00066 (Ct. Int’l Trade, filed 14 April 2025) two days earlier.⁷¹

3. Subject-matter jurisdiction is contested. 28 U.S.C. § 1581(i)(1)(B) vests exclusive jurisdiction over civil actions arising out of laws providing for “tariffs, duties, fees, or other taxes on the importation of merchandise for reasons other than the raising of revenue” in the U.S. Court of International Trade; whether California’s state-law and constitutional theories fall within that exclusive grant is the threshold question the case raises.⁸
