US Supreme Court Upholds Trump-Era Steel Tariffs, Bolsters Presidential Trade Power
Key Takeaways:
- The US Supreme Court, in a 7-2 ruling, rejected a legal challenge to the 25% tariffs on imported steel imposed in 2018.
- The court ruled the importers filed their lawsuit too late, missing a two-year deadline.
- The decision is a major win for presidential authority over trade and national security policy.
The US Supreme Court has delivered a landmark verdict, upholding the legal foundation of former President Donald Trump’s tariffs on steel imports and strengthening presidential power in trade matters.
The Core Ruling: A Matter of Timing
In a 7-2 decision, the justices dismissed the challenge not on the tariffs’ merits, but on a procedural deadline. The court ruled that a group of steel importers waited too long to sue, filing their case in 2020—two years after President Trump’s 2018 proclamation authorising the levies under Section 232 of the 1962 Trade Expansion Act.
Justice Sonia Sotomayor, writing for the majority, was clear: “Because plaintiffs did not file suit until 2020, their claims are untimely.” This leaves the 25% tariff on foreign steel firmly in place.
Dissent and Bro Implications
Justices Neil Gorsuch and Ketanji Brown Jackson dissented, warning the ruling grants presidents excessive power to impose tariffs without proper judicial oversight.
The closely watched case, PrimeSource Building Products Inc. v. United States, saw the Biden administration defending the tariffs, arguing the court lacked jurisdiction due to the missed deadline. While President Biden has kept the tariffs, his administration has negotiated quota deals with allies like the European Union.
The ruling solidifies the “America First” policy’s cornerstone and sets a precedent, ensuring the legal basis for these and potentially future similar trade actions remains intact. It marks a significant victory for executive authority in defining and acting on national security within the global trade arena.
