Constitution of the State of Indiana Art. 5, § 10

Section 10. (a) In case the Governor-elect fails to assume office, or in case of the death or resignation of the Governor or the Governor's removal from office, the Lieutenant Governor shall become Governor and hold office for the unexpired term of the person whom the Lieutenant Governor succeeds. In case the Governor is unable to discharge the powers and duties of the office, the Lieutenant Governor shall discharge the powers and duties of the office as Acting Governor.

(b) Whenever there is a vacancy in the office of Lieutenant Governor, the Governor shall nominate a Lieutenant Governor who shall take office upon confirmation by a majority vote in each house of the General Assembly and hold office for the unexpired term of the previous Lieutenant Governor. If the General Assembly is not in session, the Governor shall call it into special session to receive and act upon the Governor's nomination. In the event of the inability of the Lieutenant Governor to discharge the powers and duties of the office, the General Assembly may provide by law for the manner in which a person shall be selected to act in the Lieutenant Governor's place and declare which powers and duties of the office such person shall discharge.

(c) Whenever the Governor transmits to the President pro tempore of the Senate and the Speaker of the House of Representatives the Governor's written declaration that the Governor is unable to discharge the powers and duties of the office, and until the Governor transmits to them a written declaration to the contrary, such powers and duties shall be discharged by the Lieutenant Governor as Acting Governor. Thereafter, when the Governor transmits to the President pro tempore of the Senate and the Speaker of the House of Representatives the Governor's written declaration that no inability exists, the Governor shall resume the powers and duties of the office.

(d) Whenever the President pro tempore of the Senate and the Speaker of the House of Representatives file with the Supreme Court a written statement suggesting that the Governor is unable to discharge the powers and duties of the office, the Supreme Court shall meet within forty-eight hours to decide the question and such decision shall be final. Thereafter, whenever the Governor files with the Supreme Court the Governor's written declaration that no inability exists, the Supreme Court shall meet within forty-eight hours to decide whether such be the case and such decision shall be final. Upon a decision that no inability exists, the Governor shall resume the powers and duties of the office.

(e) Whenever there is a vacancy in both the office of Governor and Lieutenant Governor, the General Assembly shall convene in joint session forty-eight hours after such occurrence and elect a Governor from and of the same political party as the immediately past Governor by a majority vote of each house. If either house of the General Assembly is unable to assemble a quorum of its members because of vacancies in the membership of that house, the General Assembly shall convene not later than forty-eight hours after a sufficient number of the vacancies are filled to provide a quorum of members for that house.

(f) An individual holding one (1) of the following offices shall discharge the powers and duties of the governor if the office of governor and the office of lieutenant governor are both vacant, in the order listed:

(g) An individual's authority to discharge the governor's powers and duties under subsection (f) ends when the general assembly fills the office of governor under this section.
