If a majority of the qualified voters voting on the charter at the election vote in favor of the home rule charter, the charter is ratified and is the organic law of the city, and extends to all its local and city matters, unless limited by law. The charter and the ordinances made pursuant to the charter in such matters, except for matters pertaining to city elections, supersede within the territorial limits and other jurisdiction of the city any law of the state in conflict with the charter and ordinances and must be liberally construed for such purposes. Except as provided under subsection 9 of section 40-05.1-06, any ordinance enacted or adopted by a city pertaining to city elections under a home rule charter in conflict with state law is void. One copy of the charter ratified and approved must be filed with the secretary of state and one with the auditor of the city to remain as a part of its permanent records. The courts shall take judicial notice of the new charter upon its filing.
