If, after such rehearing and a consideration of all the facts, including those arising since the making of the order or decision, the commission is of the opinion that the original order or decision or any part thereof is in any respect unjust or unwarranted, or should be changed, the commission may abrogate, change, or modify it. The order or decision abrogating, changing, or modifying the original order or decision shall have the same force and effect as an orginal order or decision, but shall not affect any right or the enforcement of any right arising from or by virtue of the original order or decision unless so ordered by the commission.
