A legal advocacy group on Monday asked the US court of international trade to block Donald Trump’s sweeping tariffs on foreign trading partners, arguing that the president overstepped his authority.

The lawsuit was filed by the Liberty Justice Center, a legal advocacy group, on behalf of five US businesses that import goods from countries targeted by the tariffs.

“No one person should have the power to impose taxes that have such vast global economic consequences,” Jeffrey Schwab, Liberty Justice Center’s senior counsel, said in a statement. “The Constitution gives the power to set tax rates – including tariffs – to Congress, not the President.”
