In a September 10, 2026 amicus brief supporting the plaintiffs, three former senior U.S. trade officials, Carla A. Hills, Alan Wm. Wolff and Warren H. Maruyama, said the case concerns the executive branch's attempt to transform Section 301's "targeted authority into a sweeping power to impose broad, economy-wide tariffs untethered from the statute Congress enacted." They said the text, structure and history of Section 301 show Congress intended it to address specific foreign practices identified through a meaningful investigation and supported by findings of harm to U.S. commerce.
