Proposing a constitutional amendment to require that future constitutional amendments become effective only if approved by a majority of the voters in at least three-fourths of the counties of the state.

HJR 121 proposes a constitutional amendment that would require future Texas constitutional amendments to gain approval from a majority of voters in at least three-fourths of the state's counties to become effective. Currently, constitutional amendments only need statewide voter approval, but this change would mandate broader geographic support across the state. The amendment must be approved by voters in a November 2025 election, with the requirement taking effect January 1, 2026, for all subsequent constitutional proposals. It directly affects how future constitutional changes are enacted, ensuring they reflect support in a majority of counties rather than just statewide voter totals.
