Section 21

If, at the time fixed for the beginning of the term of the governor, the governor-elect shall have died or shall have failed to qualify, the lieutenant-governor-elect, after taking the oath of office of lieutenant-governor, may qualify as governor, and, upon so qualifying, shall become governor. The general assembly may by law provide for the case in which neither the governor-elect nor the lieutenant-governor-elect shall have qualified, by declaring who shall, in such event, act as governor or the manner in which the person who is so to act shall be selected, and such person shall act accordingly until a governor or a lieutenant-governor shall have qualified.
