In September 2025, the Supreme Court heard arguments in *Qualcomm v. US Trade Representative*, a landmark case challenging the legality of tariffs imposed by former President Trump on Chinese imports. The case centers on whether the President has the authority to impose tariffs under the International Emergency Economic Powers Act (IEEPA), particularly given the lack of explicit mention of “tariffs” within the statute.
Qualcomm, a major tech company significantly impacted by the tariffs, argues that Trump’s actions exceeded the powers granted by IEEPA. They contend that the statute was intended for genuine national emergencies, not broad trade protectionism measures. Qualcomm asserts the tariffs were a violation of the separation of powers doctrine.
The US Trade Representative defended the tariffs, claiming broad presidential authority in matters of national security and international trade. The government argued that IEEPA grants the President significant leeway to take actions necessary to protect national interests, even if those actions take the form of tariffs. They maintain the tariffs were a legitimate response to China’s unfair trade practices and intellectual property theft. The core legal dispute is whether the President’s interpretation of IEEPA’s scope is reasonable and consistent with congressional intent, especially considering the absence of the word “tariff” in the law.
