If the proposed county charter be rejected, the election of officers therein newly created is void, and the chairman of the charter commission shall require it to reconvene within 20 days and provide for revision or amendment to the original draft of the charter previously prepared by it. The commission shall complete its work within 60 days. The charter shall be submitted to the governor under the provisions of section 16. The revised charter shall be resubmitted to the electorate of the county in the same manner as in the first instance. In no case, however, shall a proposed charter be presented to the electorate by a charter commission more than twice. Whenever a charter commission has twice submitted a charter and a charter has been twice rejected by the electorate, that charter commission shall be dissolved.
