(a) All questions of order shall be decided by the President without debate, but any decision of the chair shall be subject to an appeal to the Senate by any Senator. The Senator making such appeal shall state the reasons therefor, using not more than ten minutes for such purpose, to which the President may respond. Such appeal shall be acted upon immediately, and no motion or other business, except a motion to adjourn or to take a recess, shall be entertained, until the question be determined by a majority vote of the members present.
