[US Court of International Trade Blocks US Government Tariff Measures from Taking Effect] The US Court of International Trade ruled on Wednesday local time that US President Trump did not have the authority to impose a comprehensive package of tariffs on nearly all countries, thereby declaring the April 2 "Liberation Day" tariff measures, which triggered a global trade war and could have upended the world economy, legally invalid. The Court of International Trade, located in Manhattan, New York, stated that the US Constitution grants the US Congress the exclusive power to regulate trade with other countries, and that the emergency powers claimed by the President to protect the US economy do not override these powers.
