Okla. Stat. tit. 11, § 11-13-111: Charter amendments - Procedure

Amendments to a municipal charter may be proposed by:

1. An initiative petition, signed by a number of the registered

voters residing in the municipality equal to at least twenty-five

percent (25%) of the total number of votes cast at the preceding

general election. Charter amendments proposed by initiative

petition shall be governed in all respects by the provisions of

Sections 15-101 through 15-110 of this title; or

2. A resolution of the municipal governing body. Notice of

charter amendments proposed by resolution and the election on them

shall be in the same manner provided for adoption of municipal

charters as set forth in Sections 13-106 and 13-107 of this title,

except that only the article that contains the proposed charter

amendments needs to be published and considered pursuant to those

sections.

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.
