Featured Cases
Black Voters Matter v. Byrd
Florida Supreme Court upheld the state's 2022 congressional map against voting rights groups' challenge that it diminishes Black voters' ability to elect candidates of their choice in violation of a 2010 amendment, finding the plaintiffs had not proven the possibility of drawing a remedial map that complies with the federal equal protection clause.
Evers v. Marklein
Wisconsin Supreme Court held that statutes permitting a legislative committee to pause, object to, or suspend administrative rules for varying periods of time both before and after promulgation — used by the committee in this case effectively to block for three years a rule banning “conversion therapy” for LGBTQ+ patients — facially violate the state constitution’s bicameralism and presentment requirements.
Kaul v. Urmanski
Wisconsin Supreme Court held that an 1849 law, which a local prosecutor had claimed was a near-total abortion ban, is impliedly repealed as to abortion by subsequent legislation and does not ban the procedure in the state.
Simon v. Demuth
Ruled that the quorum clause in Article IV, Section 13, of the Minnesota Constitution requires a majority of the total number of seats of which each house may consist to constitute a quorum, without reference to vacancies
Gonzales v. Markland
Held that the use of a jury district for manslaughter trial comprised of two counties did not violate the “county or district” terminology of art. 6, § 7 of the South Dakota Constitution, granting the right to a trial by a “jury of the county or district in which the offense is alleged to have been committed”
People v. Taylor; People v. Czarnecki
Michigan Supreme Court held that mandatory life-without-parole sentences violate the state constitution’s protection against “cruel or unusual” punishment for anyone under age 21 at the time of the offense. The decision extends the court’s 2022 ruling in People v. Parks that such sentences are unconstitutional for those 18 or under.
Rand v. New Hampshire
New Hampshire Supreme Court reversed trial court and held that statewide property tax scheme designed to pay for schools that allows a locality to retain any tax revenue in excess of what the district needs to fund an adequate education does not not violate a state constitutional clause empowering the legislature to levy "proportional" taxes on all New Hampshire residents. Also held that the state tax agency’s practice of setting negative local tax rates in unincorporated places with minimal or no education costs to offset nearly or completely the statewide rate does violate that clause.
Rivas v. Brownell
Held that a statute-of-limitations tolling provision in a supervisory order issued in response to the COVID-19 pandemic did not violate the separation of powers nor the affected drivers' rights to procedural due process
Planned Parenthood South Atlantic v. South Carolina (Planned Parenthood 2)
South Carolina Supreme Court held that a "fetal heartbeat" — as defined in a state law banning most abortions at the point such a heartbeat is detected — occurs when electrical impulses are first detectable as a "sound" with diagnostic medical technology and a medical professional observes those electrical impulses as a "steady and repetitive rhythmic contraction of the fetal heart." Although declining to define that point in terms of a number of weeks, the court said it "occurs in most instances at approximately six weeks of pregnancy." The court also held that the law is not unconstitutionally vague.
N'Da v. Hybl
Nebraska Supreme Court held that statutory requirement that applicant seeking certificate to provide nonemergency medical transport must show the proposed service is required by "public convenience and necessity" does not facially violate state constitutional due process or bans on "special laws" or laws granting "special privileges and immunities." Also held that that the Nebraska Constitution's due process and equal protection clauses are coextensive with their federal equivalents, so federal rational basis review applies to substantive due process challenges to economic regulations, not the heightened standard the court had applied in a line of cases from the early 20th century.
Birthmark Doula Collective v. State of Louisiana
Reproductive healthcare providers and advocates challenge a state law that reclassifies mifepristone and misoprostol as controlled dangerous substances, arguing that the law unconstitutionally regulates and delays access to medications that people need for non-abortion reasons, often for emergencies such as postpartum hemorrhage, simply because those medications may also be used for an abortion. They allege the law violates the state constitution's equal protection clause and single-subject and germane-amendment rules.
McCarty v. Missouri Secretary of State
Missouri Supreme Court held that plaintiff business groups and voters had failed to show that the ballot summary and fiscal note summary for an approved measure increasing the state's minimum wage and providing paid sick leave were inadequate or unfair. The court also held that its constitutionally and statutorily derived original jurisdiction over post-election contests is limited to matters related to the election process and does not extend to claims about the validity of a ballot measure.
Planned Parenthood of Montana v. State (Planned Parenthood 1)
Montana Supreme Court held that a 20-week abortion ban; restrictions on medication abortions, including a telehealth ban and 24-hour waiting period; and requirement that providers give patients an opportunity to view an ultrasound and listen to a fetal heartbeat violate the express right to privacy in the state constitution.
