Tariffs court fight threatens Trump's power to wield his favourite economic weapon

The ongoing court battle over tariffs could potentially limit President Trump's ability to impose tariffs as a favoured economic weapon. The dispute concerns the legality of his 2018 declaration of a national emergency to impose metals tariffs on Canada, Mexico, and the European Union.

An initial ruling declared the emergency declaration unlawful, and the administration is appealing the decision. Critics argue that the president's actions could undermine the nation's trading rights and breach international agreements.

The case is currently awaiting oral arguments before the Supreme Court, which has the potential to limit the president's authority to use tariffs as a bargaining chip in future negotiations.
