The Supreme Court on Thursday refused to overturn a ruling by the US and Mexico that struck down a trade deal between the two countries.
The Supreme Court of the United States declined to hear a case challenging the decision to strike down the Mexican-US beef deal that was signed in December.
In a 5-4 ruling, the Supreme Court said it had jurisdiction to hear the case.
The US government argued that the ruling would violate the US Constitution and international law by weakening US trade barriers with Mexico.
The court’s four conservative justices said the Trump administration’s interpretation of the trade deal “would chill the free flow of commerce and foreign investment in the United Kingdom, including by threatening to impose retaliatory tariffs on goods that would be sold in the US.”
The case was brought by the American Farm Bureau Federation and other business groups and the US Chamber of Commerce.
The trade deal, known as the Trans-Pacific Partnership (TPP), was signed by the Trump government in December 2016 and had been on the agenda of the Group of 20 (G20) summit in Hamburg.
