April 10 (UPI) -- President Donald Trump's tariffs are back in court Friday to decide on their legality.

The U.S. Court of International Trade will consider the president's 10% global tariff that he created on Feb. 20 after the U.S. Supreme Court struck down his previous tariffs over his use of emergency powers. The new tariffs are based on Section 122 of the Trade Act of 1974.

That law allows the president to unilaterally surcharge imports up to 15% for up to 150 days "to deal with large and serious United States balance-of-payments deficits."

Challenging the new levies are Democratic-led states and small businesses.
