The U.S. Supreme Court has agreed to hear a pivotal appeal by ExxonMobil and Suncor Energy seeking to dismiss climate change litigation brought by Boulder, Colorado.

A U.S. Supreme Court decision striking down emergency tariffs has sparked a trade policy crisis, with President Trump retaliating by raising duties to the legal maximum. The resulting regulatory uncertainty has stalled international trade deals and weakened the U.S. dollar as markets brace for a new wave of protectionism.
The U.S. Supreme Court has ruled 6-3 that tariffs imposed under the International Emergency Economic Powers Act (IEEPA) are illegal, nullifying President Trump's previous 35% levies. While Canadian CUSMA-compliant exports remain largely unaffected, Trump's immediate pivot to Section 122 of the 1974 Trade Act introduces new 150-day global tariffs and fresh regulatory uncertainty.
The U.S. Supreme Court has ruled that the International Emergency Economic Powers Act (IEEPA) does not grant the President authority to impose tariffs, invalidating measures introduced in 2025. This decision reinforces Congressional taxing authority and opens the door for importers to seek billions of dollars in refunds for duties collected under the now-voided executive actions.
The U.S. Supreme Court has invalidated President Trump's use of the 1977 International Emergency Economic Powers Act (IEEPA) to impose broad global tariffs. In a 6-3 decision, the court ruled that the executive branch exceeded its delegated authority, reasserting Congressional control over international trade policy.
