Amendment 3
Amendment 3
Missouri · November 3, 2026
What this measure does
Prohibit abortion in most cases, and prohibit gender transition procedures for minors under eighteen
A yes vote means
Abortion would be prohibited in most cases and gender transition procedures for minors would be banned.
A no vote means
Current abortion and gender transition medical policies would remain unchanged.
Simple explanation
This amendment would make two major changes to state law: it would ban most abortions (with some exceptions), and it would prevent doctors from providing gender transition medical procedures to people under 18. Think of it like putting new guardrails on two different medical practices that currently exist in your state.
