Missouri Amendment 3: Repeal abortion-rights amendment; ban gender transition procedures for minors
What it does. In 2024 Missouri voters added a right to reproductive freedom, including abortion through fetal viability, to the state constitution. This legislatively referred amendment would repeal that section. It would allow the legislature to regulate abortion and restrict it to medical emergencies, fetal anomalies, and rape or incest (under twelve weeks). It would also require parental consent for minors’ abortions and prohibit gender transition procedures for minors. [1] [2]
Official ballot question. Shall the Missouri Constitution be amended to: Repeal the 2024 voter-approved Amendment providing reproductive healthcare rights, including abortion through fetal viability; Allow abortions for rape and incest (under twelve-weeks’ gestation), emergencies, and fetal anomalies; Allow legislation regulating abortion; Ensure parental consent for minors’ abortions; Prohibit gender transition procedures for minors? [1]
If you vote yes
A “yes” vote will repeal Article I, Section 36, of the Missouri Constitution approved by the voters in 2024 which provided reproductive healthcare rights, including abortion through fetal viability; continue to ensure women’s ability to access medical care for medical emergencies, ectopic pregnancies, and miscarriages; allow legislation to regulate abortion providers and facilities to ensure health and safety; require informed and voluntary consent for an abortion, including parental or judicial consent for minors; allow restriction of abortions to cases of medical emergency, rape and incest under twelve weeks gestation, and fetal anomalies; prohibit public funding of abortions except in limited circumstances; and prohibit gender transition procedures for minors including gender transition surgeries, cross-sex hormones or puberty-blocking drugs, with exceptions for specific medical conditions. [1]
If you vote no
A “no” vote will leave Article I, Section 36, of the Missouri Constitution approved by voters in 2024 in place; will not limit abortion to cases of medical emergency, rape and incest under twelve weeks gestation, and fetal anomalies, but leave access to abortion available through fetal viability; will not prohibit gender transition procedures for minors. [1]
What it would cost
The official ballot title says: “State governmental entities estimate no costs or savings. Greene County estimates it may experience an unknown increase in tax revenue. Other local governmental entities estimate no costs or savings.” The fair ballot language says: “If passed, this measure will not increase or decrease taxes.” [1]
Both sides
Strongest case for
Supporters say the 2024 amendment went too far and that voters want some rules. Jamie Morris of the Missouri Catholic Conference said, “I don’t believe the average Missouri resident is comfortable with abortion with no regulations,” and called Amendment 3 “a way to craft policy more protective of mom and baby.” [2]
They say the 2024 amendment removed common-sense safeguards. The Missouri Catholic Conference says it “eliminated the legislature’s ability to set common-sense safeguards for the abortion industry,” including requirements for parental consent and clinic licensing and inspection. Priests for Life says abortion policy should “be set through the legislative process rather than by a constitutional amendment.” [2]
On the minors provision, Attorney General Catherine Hanaway (R) said the amendment is about “protecting them from making irreversible decisions before they’re old enough to fully understand dangerous consequences,” and urged voters to ensure that protection “doesn’t expire.” [2]
Strongest case against
Opponents say voters already decided this in 2024. Tori Schafer of the ACLU of Missouri said, “Missourians made clear that they want to make personal decisions around abortion care with their families and doctors, not with politicians,” and called the amendment a “trojan horse to reinstate Missouri’s total abortion ban.” [2]
Margot Riphagen of Planned Parenthood Great Rivers Action said, “The majority of Missourians want to make their own decisions about health care without interference from prying politicians.” Tom Bastian, spokesperson for the Stop the Ban campaign, said supporters are misleading voters about the minors provision. [2]
Some abortion opponents also oppose the amendment. Act for Missouri says it “does not deliver equal protection for every unborn child” and “permits abortion across multiple broad exceptions,” arguing for a measure that protects “all unborn children without exception.” [2]
What neither side is saying
Context that bears on what this measure does or who it affects but that the arguments above do not address. These are sourced facts, not arguments for or against the measure.
- Gender transition procedures for minors are already banned by state law. Ballotpedia reports that gender transition procedures for minors are currently prohibited by Missouri statute, and the Stop the Ban campaign’s spokesperson says that ban “will remain banned no matter how people vote.” The amendment would put the prohibition in the state constitution. [2]
- This would be the first repeal of a right-to-abortion amendment by voters. Ballotpedia notes that, with Missouri’s Amendment 3, “this will be the first time voters will decide to repeal a right-to-abortion amendment.” [2]
