Trump’s tariff gambit tied to India-Pakistan peace fails in US court

In a striking legal argument that underscored the geopolitical stakes of its trade policies, the Trump administration claimed that an adverse court ruling on sweeping tariffs could threaten the fragile ceasefire between nuclear-armed neighbors India and Pakistan — a submission that failed to sway the US Court of International Trade.

Last week, US Secretary of Commerce Howard Lutnick told the court that President Trump’s unilateral tariff powers were integral not just to American economic strategy, but to maintaining regional stability in South Asia. According to the filing, Trump had personally brokered a “tenuous” ceasefire between India and Pakistan, leveraging trade access as a diplomatic tool to avert all-out war.

“An adverse ruling by this court that constrains the President's powers could lead India and Pakistan to question the validity of Trump's offer, threatening the security of an entire region and the lives of millions,” Lutnick stated in the May 23 filing.

Despite the dramatic warning, the court rejected the administration’s argument, ruling that the President had “overstepped his authority” by attempting to impose blanket tariffs without congressional approval. The court emphasized that the Constitution grants exclusive power to Congress to regulate commerce with foreign nations — a power that cannot be unilaterally overridden by the executive branch.

Trump has long claimed credit for halting hostilities between India and Pakistan, asserting that his trade threats compelled both sides to the negotiating table. However, India has consistently dismissed these assertions, maintaining that the ceasefire was reached through direct bilateral engagement without U.S. intervention.

Trade tensions with China also cited

Beyond South Asia, the administration argued that its tariff strategy had successfully pressured China—described as the “greatest contributor to the national emergency”—into negotiating. The US and China had recently agreed to a temporary truce on escalating tariffs, with some levies reaching as high as 145% on Chinese imports and 125% on US goods.

According to Lutnick, Trump’s aggressive trade posture forced adversarial trading partners to re-engage diplomatically. “Foreign trading partners that have run trade deficits in goods for years and helped hollow out the American manufacturing base immediately came to the negotiating table,” he said.

On April 2, Trump unveiled a wide-reaching set of reciprocal tariffs against multiple nations, including India, only to pause them a week later. The administration framed the pause as a gesture to encourage diplomatic resolution—but the court remained unconvinced.

A legal and political setback

The ruling marks a significant setback for Trump’s trade policy and a broader challenge to executive overreach. By rejecting the premise that presidential tariff powers are a tool for global conflict resolution, the court reaffirmed the foundational role of congressional oversight in trade and diplomacy.

The Trump administration has yet to respond publicly to the court’s decision, but legal analysts suggest the ruling could limit the future scope of executive action on trade —especially when national security is invoked to justify economic maneuvers.

As the White House weighs its next move, the message from the bench is clear: even the highest-stakes geopolitical claims are not above constitutional checks and balances.
