Top court turns away challenge to Trump’s tariffs on steel products

The U.S. Supreme Court left intact President Donald Trump’s 25-per-cent tariffs on imported steel products, rejecting an industry trade group challenge that sought to strip the president of a powerful legal tool for imposing duties.

The rebuff marks the second time the justices have turned away the American Institute for International Steel on Trump’s tariffs. The court made no comment in refusing to hear the group’s appeal.

The appeal contended that the provision Trump invoked, known as Section 232, gives the president such broad discretion to impose tariffs on national security grounds that it violates the constitution.

“Section 232 is astonishing in the breadth of discretion, both in the finding that triggers its application and in the completely unbounded choice of remedies afforded the president, including the amount of any tariffs or quotas,” the trade group argued.

The industry group said a ruling in its favour would have let companies recoup some of the US$6 billion-plus in tariffs that have been paid so far.

Trump imposed the 25-percent steel tariff, along with a 10-per-cent duty on aluminum imports, in March 2018. Some countries, including Brazil and South Korea, have negotiated deals to avoid the tariff, and Trump dropped the duty for imports from Canada and Mexico.

But the tariffs still apply for much of world, including the European Union and China and Japan. Trump has also threatened to invoke Section 232 to place tariffs on imported automobiles and parts.

The trade group pointed to the “nondelegation doctrine,” a rarely used constitutional rule that says Congress must give clear guidance to an agency before handing off its legislative responsibilities.

The Supreme Court’s conservatives indicated in a ruling last year they are interested in revitalizing the nondelegation doctrine.
