When a question of law, fact or procedure has been presented to a judge, the same question, so far as it relates to the same case, shall not thereafter knowingly be presented to another judge sitting in the district without apprising the subsequent judge of the former judge's ruling or, if no ruling has been made, that such question has already been presented to the first judge. Where this rule has been violated, an order that is issued by the second judge may be vacated by him at any time before the entry of a final judgment.
