If, at the time the Legislature shall canvass the election returns for the offices of Governor and Lieutenant Governor, the person receiving the highest number of votes for the office of Governor, as declared by the Speaker, has died, fails to qualify, or for any other reason is unable to assume the office of Governor, then the person having the highest number of votes for the office of Lieutenant Governor shall become Governor for the full term to which the person was elected as Governor. By becoming the Governor, the person forfeits the office of Lieutenant Governor, and the resulting vacancy in the office of Lieutenant Governor shall be filled as provided by Section 9, Article III, of this Constitution. If the person with the highest number of votes for the office of Governor, as declared by the Speaker, becomes temporarily unable to take office, then the Lieutenant Governor shall act as Governor until the person with the highest number of votes for the office of Governor becomes able to assume the office of Governor. Any succession to the Governorship not otherwise provided for in this Constitution, may be provided for by law; provided, however, that any person succeeding to the office of Governor shall be qualified as otherwise provided in this Constitution, and shall, during the entire term to which he may succeed, be under all the restrictions and inhibitions imposed in this Constitution on the Governor.
