Nine months after the UK Supreme Court made a crucial decision that effectively forced Uber Technologies Inc. to provide worker rights for its riders, the firm is back in court accused of trying to undermine the judgment. Uber has challenged a small part of the landmark ruling, where a judge’s comments suggest the tech firm should enter into a direct contract with passengers when providing car journeys. The ride hailing-app is seeking a ruling that, that isn’t the case, which it argues is in line with the London transport regulator’s guidance.
