Amendments to this Constitution may be proposed by the Osage Nation Congress. Proposed amendments agreed to by five-sixths (5/6) of the members in Congress shall be put before the Osage People for their approval or rejection at the next general election, except when the legislature shall order a special election for that purpose.

If at least sixty-five percent (65%) of Osage electors voting on a proposed amendment approve the same, it shall become part of the Constitution and shall abrogate or amend existing provisions of the Constitution at the end of thirty (30) days after the date of the election at which it was approved.
