The U.S. Court of International Trade is hearing arguments in an attempt to overturn the temporary tariffs imposed by President Donald Trump after the Supreme Court rejected his preferred choice of larger, more sweeping tariffs. The tariffs are set to expire on July 24. The issue is whether Section 122 of the Trade Act of 1974, which allows the president to impose global tariffs of up to 15% for 150 days, should it be extended without congressional approval. Critics argue that Section 122's use is obsolete due to the era of the dollar being tied to gold.
