(Jan 21): The US Supreme Court didn’t rule on President Donald Trump’s tariffs on Tuesday, meaning it probably will be at least another month before a challenge to his signature economic policy is resolved. The court is preparing to begin a four-week recess, and under its usual procedures for releasing opinions, the next potential day for a tariff decision is Feb 20. A ruling against Trump on tariffs would deliver his biggest legal defeat since returning to the White House. It could also undercut his threat to impose more tariffs on European countries that are resisting his attempt to take over Greenland. Although the justices will be hearing arguments on Wednesday on Trump’s effort to oust Federal Reserve governor Lisa Cook, the court isn’t scheduled to release opinions.
