(a) After a charter commission has been created, any smaller city within the county may by action of its legislative body appoint a representative to consult with the charter commission concerning the terms upon which the functions of such smaller city may be included in the proposed consolidation. Any terms proposed by the charter commission with respect to the smaller city shall be filed and published separately as an appendix to the metropolitan charter proposed with respect to the principal city, and shall be submitted independently in a special referendum election for ratification or rejection by the voters of the smaller city and by the voters of the county outside the smaller city in a manner similar to that provided in §§ 7-2-105 and 7-2-106 with respect to the proposed metropolitan charter for the principal city.

(b) The appendix shall be deemed ratified and adopted if it is approved by a majority of those voting within the smaller city and also by a majority of those voting in the county outside of such smaller city, but shall not become effective unless the proposed metropolitan charter with respect to the principal city and the county is ratified and adopted.

(c) The appendix shall be deemed rejected and shall not become effective if it is disapproved by a majority of those voting in the smaller city. It shall also be deemed rejected and shall not become effective if it is disapproved by a majority of those voting in the county outside of such smaller city.

(d) The returns of the referendum election on the proposed appendix shall be certified and proclaimed in a manner similar to that provided in § 7-2-106 with respect to the proposed metropolitan charter for the principal city.

(e) Where a proposed charter of metropolitan government is ratified by a majority of those voting in a principal city and of those voting in the county outside of the principal city, but a smaller city continues, either because a proposed appendix has been rejected or no such appendix has been proposed, the smaller city shall become a part of the general services district, but the smaller city may not thereafter be included within the urban services district by action of the metropolitan council.
