United States (US) President Donald Trump responded with fury to Friday’s Supreme Court ruling that he did not have the power to unilaterally set tariffs on imports, denigrating individual justices as he vowed to wield a more restrictive law to continue his global trade war.

He vowed he would not be deterred by what he repeatedly called a ridiculous ruling, announcing to reporters at the White House an immediate new tariff of 10% on imports from all countries on top of any existing tariffs, for up to the maximum 150 days allowed by Congress.

The court’s landmark 6-3 ruling upended the leverage Trump, and his trade envoys have wielded over foreign governments, both allies and foes, at negotiating tables around the world to reshape diplomatic relations and global markets.

It called into question the many trade deals his envoys have negotiated in recent months under the threat of high tariffs.

The ruling briefly sent US stock indexes surging, before ending modestly higher as analysts warned of renewed confusion in global markets while they await Trump’s next moves.

It left open the fate of the $175 billion Trump has collected from US importers under what the court said was his incorrect reading of the law.

“I’m ashamed of certain members of the court, absolutely ashamed, for not having the courage to do what’s right for our country,” Trump told reporters at the White House, complaining that foreign countries were ecstatic at the ruling and were “dancing in the street.”
