Amendment L would require a constitutional amendment in South Dakota to receive at least 60% of votes cast before taking effect. It is a legislative referral for the November 2026 election. Raising the threshold would make the Constitution harder to change through both citizen-backed and legislatively referred amendments. Supporters of supermajority rules generally view a constitution as a durable framework that should require broad consensus; opponents argue that a minority should not be able to defeat a proposal supported by a clear majority of voters. Constitutions should be more stable than ordinary statutes, but the amendment process is also a tool voters use when ordinary government will not act. The threshold should reflect how much stability is worth giving a losing minority extra blocking power.
