Wyoming heartbeat abortion ban takes effect immediately as clinic vows legal challenge

Wyoming Governor Mark Gordon signed House Bill 126, known as the Human Heartbeat Act, into law on Monday, banning abortion in Wyoming once cardiac activity is detected in a fetus. The law took effect immediately upon signing, making Wyoming the fifth state in the United States to enact a six-week abortion restriction, joining Florida, Georgia, Iowa, and South Carolina. Thirteen other states maintain broader bans prohibiting abortion at all stages of pregnancy, with limited exceptions.

The Human Heartbeat Act prohibits abortion once embryonic cardiac activity is identified, which typically occurs around six weeks of gestation, before many women are aware they are pregnant. If cardiac activity is detected, abortion may only be performed where the life of the pregnant person is in danger or where continuing the pregnancy would cause serious or irreversible impairment of a major bodily function. The bill does not include exceptions for pregnancies resulting from rape or incest, an omission that Governor Gordon identified as a direct flaw in the legislation.

The Wyoming House of Representatives and Wyoming State Senate transmitted House Bill 126 to Governor Gordon’s desk on Friday. The bill was sponsored by Wyoming House Speaker Chip Neiman. Under the Human Heartbeat Act, any person who intentionally or knowingly performs, induces, or attempts to induce an abortion after a detectable heartbeat is found faces a felony charge punishable by up to five years in prison, a fine of up to ten thousand dollars, or both. Medical providers who fail to check for cardiac activity prior to performing an abortion face the same criminal exposure, along with potential license revocation.

The law requires that determination of a heartbeat shall be made using standard medical practices and techniques. Early detection at six weeks of gestation may require a transvaginal ultrasound, an invasive procedure that has itself been the subject of separate legislative and legal disputes in Wyoming. Governor Gordon vetoed a bill in 2025 that would have required patients seeking abortion medication to undergo a transvaginal ultrasound and a 48-hour waiting period. The Wyoming Legislature overrode that veto, and litigation challenging that requirement remains pending with a judicial hold in place.

Why did Wyoming Governor Mark Gordon sign a law he publicly described as legally fragile and likely to be overturned in court?

Governor Gordon’s signing letter to House Speaker Chip Neiman was unusually candid in expressing doubt about the legislation’s durability. Gordon described the Human Heartbeat Act as “another well-intentioned but likely fragile legal effort with significant risk of ending in the courts rather than in lasting, durable policy,” and wrote that he feared the state had “only added another chapter to the sad saga of repeatedly trying to force a specific solution.” Despite those reservations, he affirmed his support for the law’s underlying purpose, writing that he “resoundingly” shares the determination to defend the lives of unborn children and supports the intentions behind the act.

Gordon’s skepticism was grounded in Wyoming’s specific constitutional history. The Wyoming Supreme Court ruled in January 2026 that a pair of 2023 abortion bans were unconstitutional under the Wyoming State Constitution, concluding that the state’s constitution does not permit an outright ban on abortion. That ruling ended a multi-year legal contest that had kept Wyoming’s previous restrictions tied up in litigation for years. Governor Gordon had explicitly called on the Wyoming Legislature during his State of the State address earlier this year to pass a constitutional amendment that would allow Wyoming voters to decide the issue directly and establish a legally durable framework for future restrictions. A constitutional amendment bill was introduced during the legislative session but failed to advance in the Wyoming State Senate.

Gordon also expressed specific concern about the law’s lack of rape and incest exceptions. He wrote that this represented “an unfortunate flaw,” adding that the omission does not align with his pro-life stance regarding the welfare of specific vulnerable populations. The governor nonetheless signed the measure, stating that the state must protect unborn life while acting carefully within the constraints of the Wyoming Constitution and existing court decisions.

How does Wyoming’s Human Heartbeat Act include a legal contingency if it is struck down by the courts?

The Human Heartbeat Act contains a built-in fallback mechanism. If the law is ruled unconstitutional and struck down in court, the Wyoming Attorney General, Secretary of State, and Wyoming Legislature must formally certify that the law cannot be enforced. Following that certification, Wyoming state law would revert to the viability standard that was in place before Roe v. Wade. This provision reflects the legislature’s acknowledgment that the law may face the same judicial fate as the 2023 restrictions, while seeking to prevent a legal vacuum in the event of an adverse ruling.

What is the medical and scientific debate over the term fetal heartbeat at six weeks of gestation?

The terminology embedded in the Human Heartbeat Act is contested on scientific grounds. While embryonic cardiac activity can be detected at approximately six weeks of gestation, physicians and medical associations note that the term “fetal heartbeat” is a clinical misnomer at that developmental stage. An embryo at six weeks has not developed cardiac valves. What is detectable is electrical activity in the cells that will eventually form the heart, not a functioning heartbeat in the established medical sense. Critics of the statutory language argue that the term is designed to invoke an emotional and symbolic association that does not reflect the embryological reality, while supporters of the law maintain that the detection of any cardiac activity is a meaningful marker of developing life.

How does Wyoming’s new abortion restriction compare to the broader national landscape of state abortion laws after the Dobbs decision?

The United States Supreme Court’s ruling in Dobbs v. Jackson Women’s Health Organization in June 2022 overturned Roe v. Wade, returning full authority over abortion regulation to individual state legislatures and courts. That decision set off a rapid restructuring of abortion access across the country, with states in the South and Mountain West moving quickly to enact bans or restrictions while states with Democratic-controlled legislatures passed legislation protecting or expanding access. Wyoming’s case is distinctive within this national pattern because the Wyoming State Constitution has been interpreted by the Wyoming Supreme Court as providing affirmative protections that constrain the legislature’s ability to impose a complete ban on abortion. The Human Heartbeat Act’s focus on the detection of cardiac activity, rather than a blanket prohibition, represents the Wyoming Legislature’s attempt to find a restriction that can withstand constitutional review, though Governor Gordon publicly expressed doubt that the current measure would survive judicial scrutiny.

What is the current status of abortion access in Wyoming and how has Wellspring Health Access responded to the new law?

Abortion access in Wyoming has been subject to significant disruption over the past several years. The state’s only abortion clinic, Wellspring Health Access in Casper, was set on fire in 2022, delaying its opening. At various periods the clinic has operated offering only medication abortion rather than surgical procedures. The Wyoming State Health Department reports that 625 abortions were performed in Wyoming in 2024, the most recent year for which compiled records are available. Katie Knutter, executive director of Wellspring Health Access, said the clinic performed 303 abortions in 2025 and that staff began on Monday referring patients who are further along in their pregnancies to providers in other states.

Julie Burkhart, president of Wellspring Health Access, stated that the organization is prepared to challenge the Human Heartbeat Act in court and will continue working with regional and national partners to ensure patients can access care. Burkhart described the law as an attack on the constitutional rights of Wyoming residents to make their own health care decisions and said that the law puts the health and well-being of communities at risk. She added that every day the law remains in effect means people in Wyoming will face greater barriers to abortion care, and that some may be denied care entirely.

Key takeaways on what Wyoming’s Human Heartbeat Act means for abortion access, state law, and the national policy landscape
