Amendments to a municipal charter may be proposed by:
If a majority of the votes cast in the election on the charter amendments, as certified by the secretary of the county election board, are in favor of adopting the proposed amendments to the charter, the charter shall be so amended, certified and authenticated by the mayor, and submitted to the Governor for approval. The Governor shall approve the charter amendments if they are not in conflict with the Constitution and laws of Oklahoma. Upon approval, the charter as amended shall become the organic law of the municipality and supersede any existing charter and all ordinances in conflict with it. The charter amendments shall be filed and recorded in the same manner provided for filing of municipal charters.
