MILAN/FRANKFURT/LONDON/PARIS - From European wine makers to chemical companies and distillers, the

US Supreme Court ruling knocking down a large part of US President Donald Trump’s trade tariffs

comes with a sting in the tail - an even more uncertain trade outlook. In a decision that will ripple through the global economy, the top US court struck down Mr Trump’s sweeping tariffs imposed under a law meant for use in national emergencies, handing a stinging defeat to the Republican president. But while many businesses cheered after lengthy legal battles against tariffs, European trade groups, companies and analysts worried that the ruling may make trade relations even more messy after hard-struck trade deals last year.
