The "Protect Our Constitution Act" amends the Arkansas Constitution regarding the percentage of votes required for the approval of constitutional amendments. Under the new provisions, a constitutional amendment must now receive at least two-thirds (2/3) of the votes cast to take effect, as opposed to the previous requirement of a simple majority. This change is intended to ensure that any amendments to the Constitution have substantial support from voters, thereby justifying the alteration of the state's foundational legal document.

Additionally, the bill includes an emergency clause, which states that the amendments are necessary for the preservation of public peace, health, and safety, and should take effect immediately to be in place for the 2026 general election. The act clarifies that measures approved by voters will become law 30 days after the election unless specified otherwise, and it also addresses the handling of conflicting measures by stipulating that the one with the highest number of affirmative votes will prevail.
