Section 131

When the office of the governor shall become vacant, by death or otherwise, the lieutenant-governor shall possess the powers and discharge the duties of said office. When the governor shall be absent from the State, or unable from protracted illness to perform the duties of the office, the lieutenant-governor shall discharge the duties of said office until the governor be able to resume his duties; but, if from disability or otherwise, the lieutenant-governor shall be incapable of performing said duties, or if he be absent from the State, the president of the senate pro tempore shall act in his stead; but if there be no such president, or if he be disqualified by like disability, or be absent from the State, then the speaker of the house of represenatives shall assume the office of governor, and perform said duties; and in case of the inability of the foregoing officers to discharge the duties of governor, the secretary of state shall convene the ​senate, to elect a president pro tempore. The officer discharging the duties of governor shall receive the compensation as such. Should a doubt arise as to whether a vacancy has occurred in the office of governor or as to whether any one of the disabilities mentioned in this section exists or shall have ended, then the secretary of state shall submit the question in doubt to the judges of the supreme court, who, or a majority of whom, shall investigate and determine said question; and shall furnish to said secretary of state an opinion in writing determining the question submitted to them, which opinion when rendered as aforesaid shall be final and conclusive.
