2024 Colorado Amendment J is an amendment to the Colorado Constitution that appeared on the general election ballot on November 5, 2024, in Colorado. As it passed, the amendment repealed Amendment 43, a 2006 constitutional ban on same-sex marriage in the Constitution of Colorado. While Constitutional ballot measures typically require a 55% vote to pass in Colorado, Amendment J only needed a simple majority. This is because the 55% vote threshold only applies to proposed amendments adding to the Constitution, not those which repeal provisions from it.[2]
