Succession when neither Governor-elect nor Lieutenant Governor-elect qualifies or is able to serve. In the event that neither the Governor-elect nor the Lieutenant Governor-elect shall qualify, or if after taking the oath of office neither shall be able to serve for any reason whatsoever, the office of Governor for the time being shall devolve upon such officers and in such order of succession as may be provided by law.
