Repealing the 2024 reproductive-rights amendment, allowing abortion only under listed exceptions, and prohibiting gender transition procedures for minors.

No vote

The question to ask yourself

Should Missouri replace the 2024 abortion protections with narrower exceptions and a constitutional ban on gender-transition procedures for minors?

The case for

  • It restores parental-consent requirements for minors' abortions.
  • It places restrictions on minor gender-transition procedures in the constitution.

The case against

Money
State and local governmental entities estimate no costs or savings, and the measure will not increase or decrease taxes.
Don't be misled
Calling it a total abortion ban is misleading because the proposal includes exceptions, but calling it only a minor-care measure is also misleading because its main effect is changing abortion rights.
