As former President Donald Trump pushes forward with his plan to impose an 80% tariff on Chinese goods, legal scholars and trade analysts are raising red flags about whether such a sweeping policy could survive a courtroom challenge. With high-level U.S.-China negotiations underway in Switzerland, Trump’s aggressive stance is once again testing the boundaries of presidential authority over international trade.

The Legal Foundation for Tariff Power
At the center of this controversy lies the International Emergency Economic Powers Act (IEEPA), a statute that grants the president broad authority to regulate commerce during national emergencies. Trump has previously cited IEEPA to justify increased tariffs, claiming threats like Chinese economic manipulation and fentanyl trafficking warrant emergency action. Supporters argue that these national security claims give the president leeway to act swiftly without waiting on Congress.
However, critics counter that IEEPA was never intended to give the executive branch blanket authority to tax foreign goods. Legal experts point to the lack of direct language in the statute authorizing tariffs, arguing that Trump’s use of IEEPA skirts the traditional separation of powers between the legislative and executive branches. Courts have historically given presidents wide latitude in foreign affairs, but this new tariff proposal may cross a constitutional line.
Legal Challenges on the Horizon
Multiple lawsuits are already in motion challenging similar tariff actions from the Trump administration’s earlier term. The Liberty Justice Center and other legal organizations are preparing new filings in anticipation of another major trade move. These groups represent small business owners and importers who claim such tariffs create economic hardship without proper legislative oversight.
States like California and New York are also considering joining potential litigation, citing the economic harm done to local industries. Their legal argument hinges on the claim that only Congress has the explicit authority to impose duties under the Constitution’s Commerce Clause. Should Trump follow through on the 80% tariff, it’s likely a legal battle will ensue almost immediately, potentially landing in the Supreme Court.
Congress Reasserts Its Role
In response to Trump’s escalating tariff threats, lawmakers on both sides of the aisle have introduced the Trade Review Act of 2025. This bill seeks to rein in presidential authority by requiring congressional approval for any new tariffs over 20%. It’s part of a broader effort to rebalance trade policy after years of executive dominance.
Supporters of the bill argue that it would restore accountability and protect U.S. consumers from abrupt changes in trade strategy. While the measure has gained momentum, it faces a tough battle in the Senate, where partisan loyalties to Trump could influence the outcome. Still, the bill’s very existence highlights growing discomfort with unchecked executive control over global commerce.
The Road Ahead
If Trump’s tariff plan is implemented and challenged in court, the outcome could reshape U.S. trade law for decades. The judiciary will be forced to decide whether economic emergency declarations give presidents near-absolute power over tariffs or whether constitutional limits still apply. With billions in global trade hanging in the balance, the stakes couldn’t be higher.
For now, China has responded cautiously, awaiting the results of the Switzerland negotiations. However, if Trump’s proposal becomes official policy, expect a flurry of lawsuits, legislative pushback, and international retaliation. The legal system may soon be the final arbiter in one of the most significant trade disputes of the modern era.
