1. Taxation is a Congressional Power

The core of the Supreme Court Tariff Ruling lies in the constitutional separation of powers. The Court clarified that tariffs are fundamentally a form of taxation. According to Article I of the Constitution, the power to lay and collect taxes belongs exclusively to Congress. By invoking the International Emergency Economic Powers Act (IEEPA) to impose global tariffs, the executive branch was deemed to have exceeded its legal mandate.

2. Global Markets in a Whirlwind

The reaction from Wall Street and international stock exchanges was instantaneous. US futures and world markets showed a mixed but volatile response as investors adjusted to the prospect of a less protected domestic market. The intersection of global trade and domestic law has never felt more vibrant than it did during this morning’s session.

President Trump was quick to express his disappointment with the ruling, but he has not folded his hand. Almost immediately, the administration indicated it would pursue alternative legal avenues, including Section 122 of the US Trade Act of 1974. The legal battle over executive trade power is far from over.
