US Supreme Court Delays Ruling on Trump's Global Tariffs Challenge
The US Supreme Court did not rule Friday on Trump's global tariffs case, leaving the major constitutional challenge unresolved. The case tests presidential emergency powers under the 1977 International Emergency Economic Powers Act, which Trump invoked citing trade deficits and fentanyl trafficking. Businesses and 12 states challenge the tariffs, with lower courts ruling Trump overstepped authority, while the outcome carries significant global economic implications.

The US Supreme Court did not issue a ruling on Friday in a major constitutional case challenging President Trump's sweeping global tariffs, leaving businesses and markets in continued uncertainty. The justices issued only one ruling on Friday in an unrelated criminal case, as the court does not announce in advance which cases will be decided.
Constitutional Challenge Over Presidential Powers
The tariffs case represents a significant test of presidential authority and the Supreme Court's willingness to impose limits on executive power. During oral arguments heard on November 5, both conservative and liberal justices appeared to express skepticism about the legality of the tariffs.
| Case Details: | Information |
|---|---|
| Legal Basis: | International Emergency Economic Powers Act (1977) |
| Scope: | Global tariffs on nearly every foreign trading partner |
| Challengers: | Affected businesses and 12 US states |
| Lower Court Ruling: | Trump overstepped his authority |
Tariff Implementation and Justification
Trump invoked the International Emergency Economic Powers Act to impose "reciprocal" tariffs on goods imported from individual countries, affecting nearly every foreign trading partner. The administration justified these measures by declaring a national emergency related to US trade deficits.
Additionally, Trump used the same 1977 law to impose specific tariffs on China, Canada, and Mexico, citing the trafficking of fentanyl and other illicit drugs into the United States as constituting a national emergency.
Market Impact and Economic Implications
The ongoing legal uncertainty continues to affect global markets, with the outcome expected to have significant implications for international trade. As of January 9, 2026, at 02:30 AM IST, US markets showed mixed performance:

Political Stakes and Administration Response
Trump has defended the tariffs, stating they have made the United States stronger financially. In a social media post on January 2, he characterized a potential Supreme Court ruling against the tariffs as a "terrible blow" to the United States.
The Trump administration is currently appealing lower court rulings that determined the president overstepped his constitutional authority in implementing the tariffs. The challenge has been brought by businesses directly affected by the tariff policies and 12 US states, most of which are under Democratic governance.
The Supreme Court's eventual decision will establish important precedent regarding the scope of presidential emergency powers and their application to international trade policy.
