A referendum on the Amendment 1 to the Constitution of Hawaii was held on 5 November 2024. The amendment repealed the Hawaii's legislature's ability to limit marriage to heterosexual couples,[2] reversing the 1998 Hawaii Amendment 2.[3] The majority of the voters backed the measure;[1] it succeeded in all four of Hawaii's major counties. The wording of the ballot language proved confusing to a number of voters, who were unsure of what the amendment accomplished.[4] The amendment passed simultaneously with similar ones in California and Colorado.[5][6]
