The original Indiana constitution was adopted without being submitted to the people. The current constitution is the Constitution of 1851, with numerous amendments. The Constitution consists of a preamble and 16 articles.
Article 16 provides legislatively-referred constitutional amendment process as follows:
- Either chamber of the Indiana General Assembly can propose an amendment
- A simple majority of the members elected to each of the two chambers is required.
- The same amendment can be proposed in the next session of the legislature, if there is simple majority.
- The amendment will be submitted to a statewide vote of the people at a general election.
- The proposed amendment becomes part of the Indiana Constitution, if a majority of the voters approve it.
