President Donald Trump has already leaned on alternative legislation to try to rebuild his tariff wall, after the US Supreme Court ruled that he can’t use a 1977 emergency law to impose import taxes. The court said that Trump exceeded his authority by invoking the International Emergency Economic Powers Act to justify his sweeping “reciprocal” duties targeting America’s trading partners, as well as separate levies aimed at China, Canada and Mexico. The ruling invalidates a large portion of the tariffs that Trump has rolled out in his second term, but there are other ways that he can introduce import taxes. While the Constitution gives Congress the power to levy taxes and duties, lawmakers have delegated some authority to the executive branch through a number of statutes.
