Representatives from the steel industry went up to the Hill this week to challenge President Trump's tariffs on global steel imports, but the U.S. Supreme Court refused to hear the case, according to Supply Chain Dive. The representatives from the steel industry argued the tariffs are unconstitutional. Since the Supreme Court refused the case, those from the steel industry have the option to present their case to a lower court.

The industry's representatives argued the president is practicing "too broad of an authority under Section 232 of the Trade Expansion Act of 1962," according to Supply Chain Dive. The main sticking point revolves around the 25% tariff on steel imports from all countries, excluding Argentina, Australia, Brazil, Canada, Mexico and South Korea.

"It's an extraordinarily broad grant of authority, and the president's actions under the statute have imposed billions of dollars worth of losses on the American economy as a whole," Tim Meyer, a law professor at Vanderbilt University and counsel for the petitioners in this case, told Supply Chain Dive.
