Notwithstanding any provision of law which limits ad valorem tax millages to be imposed, the governing authority of any district of a governmental entity, which operates pursuant to a charter for local self-government or other home rule charter, may propose and levy special millages, not inconsistent with the charter of the governmental entity or the Constitution of Louisiana, for a period not to exceed ten years, if the question of levying such tax is approved by a favorable vote of a majority of the electors of the district voting in an election called for that purpose.
