The government of Indiana is established and regulated by the Constitution of Indiana. The state-level government consists of three branches: the judicial branch, the legislative branch, and the executive branch. The three branches share power and jointly govern the state of Indiana. County and local governments are also constitutional bodies with limited authority to levy taxes, pass legislation, and create and maintain local public infrastructure.
