PORTALBERITA.CO.ID - The United States Supreme Court has decided not to impose new limitations on the tariff authority exercised by former President Donald Trump during his first term, effectively allowing existing import taxes on hundreds of billions of dollars worth of Chinese merchandise to remain in place. This major development in trade law occurred on Monday, June 15.
As reported by Businesstimes, the high court rejected an appeal filed by a coalition of importing companies, thereby allowing a 2025 ruling from a federal appeals court that supported the duties to stand without issuing any further official commentary on the matter.
The core of this prolonged legal conflict centered on the scope of executive power concerning the modification of trade duties initially established under Section 301 of the 1974 Trade Act, which is statutorily designed to counter unfair international trade practices.
A lesser-known provision, Section 307, grants the sitting president the authority to terminate or alter existing tariffs at a subsequent date through the office of the United States Trade Representative.
The challenging importing companies contended that President Trump exceeded his legal authority by employing Section 307 to escalate trade penalties that originally targeted US$50 billion in imports from China, measures intended to force changes in Chinese intellectual property policies.
Following significant retaliatory actions initiated by China, the Trump administration subsequently broadened the scope of this policy, which ultimately affected a staggering US$370 billion worth of imported products by the year 2019.
Importers argued directly to the Supreme Court that the former President sought to utilize Section 307 specifically to circumvent the more rigorous procedural prerequisites explicitly mandated under Section 301.
The US Court of Appeals for the Federal Circuit had previously dismissed this specific legal interpretation in September, asserting that the term "modify" carries no inherent limitations and remains neutral regarding the extent of the change involved.
Petitioners subsequently urged the Supreme Court justices to mandate a review of the case, particularly citing a recent February 20 ruling that had invalidated global tariffs imposed by Trump the previous year utilizing federal emergency-powers legislation.
