Start with Wis. Stat. § 253.107 (20-week LMP / pain-capable framework); 1849 ban held impliedly repealed — Kaul v. Urmanski, 2025 WI 32. In Wisconsin, Gestational limit. Approximately 20 weeks LMP (pain-capable / viability-adjacent regulation) is the enforceable gestational framework after Kaul; the 1849 near-total ban does not prohibit abortion.. That is the question this guide answers for whether abortion is legal. In Kaul v. Urmanski, 2025 WI 32, the Wisconsin Supreme Court held that the 1849 abortion ban was impliedly repealed and does not prohibit abortion. The operative rule is therefore gestational regulation around a 20-week LMP / pain-capable framework, plus clinic and informed-consent rules—not an unclear near-total ban. Access before that threshold remains available subject to ordinary regulations. Confirm any legislative response after Kaul.

Post-Kaul, criminal exposure under the 1849 statute is not the governing ban theory; providers still must comply with § 253.107 and medical regulations.
Federal constitutional law no longer supplies a nationwide right to abortion after Dobbs. State constitutions, statutes, and injunctions still matter enormously — and they change when legislatures amend trigger laws, voters pass ballot measures, or courts enter or lift stays.

Gestational limits and exceptions
Limit: Approximately 20 weeks LMP (pain-capable / viability-adjacent regulation) is the enforceable gestational framework after Kaul; the 1849 near-total ban does not prohibit abortion.
Exceptions and carve-outs: After the 20-week LMP threshold, procedures are limited to life/health and other statutory exceptions under § 253.107 and related provisions.
Clinics, hospitals, and telehealth providers may also face facility licensing, reporting, parental-involvement, and informed-consent rules that are separate from the core ban-or-protect statute. Those rules can affect how care is delivered even when abortion remains lawful in Wisconsin.

Wisconsin answers the legality question from Wis. Stat. § 253.107 (20-week LMP / pain-capable framework); 1849 ban held impliedly repealed — Kaul v. Urmanski, 2025 WI 32. Federal constitutional law no longer supplies a nationwide right after Dobbs.
Federal backdrop after Dobbs
Dobbs overruled Roe and Casey and held that the U.S. Constitution does not confer a right to abortion, returning the issue to “the people and their elected representatives.” That holding does not erase Wisconsin law — it makes Wisconsin law decisive. Interstate travel, FDA medication-abortion rules, EMTALA emergency-care disputes, and Medicaid funding fights can still surface in federal court, but the everyday legality question for a patient or clinic in Wisconsin is answered first by Wis. Stat. § 253.107 (20-week LMP / pain-capable framework); 1849 ban held impliedly repealed — Kaul v. Urmanski, 2025 WI 32 and Wisconsin case law.
