Page "Governor of Indiana" Paragraph 14

If the governor becomes incapacitated, then the Lieutenant Governor of Indiana becomes acting-governor until his recovery.

Only two governors have became incapacitated during their terms, and current precedent is that the governor's office is to notify the lieutenant governor, who will then make the decision to become acting-governor by notifying the General Assembly by letter.

The governor can resume his powers & duties by sending a letter to the General Assembly notifying them that he is again capable of executing the duties of office.

If the governor resigns, dies, or is impeached, tried, and convicted, then the lieutenant governor becomes governor.

If the office of the lieutenant governor is vacant, then the Senate Pro-Tempore becomes governor.

If the office of Senate President pro tempore is also vacant, then the Senate must elect a new Pro-Tempore to fill the governor's office.
