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Supreme Court held that an 1849 law, which a local prosecutor had claimed was a near-total abortion ban, is impliedly repealed as to abortion by subsequent legislation and does not ban the procedure in the state.
State v. Hoyle
Wisconsin Supreme Court reversed Court of Appeals's grant of new trial, finding that prosecutor did not unlawfully comment on defendant's exercise of his Fifth Amendment right to remain silent. On remand, Court of Appeals rejected defendant's other bases for overturning his conviction, finding no reasonable probability that newly discovered evidence would have changed the jury's verdict and evidence the prosecution did not disclose to be immaterial. The Wisconsin high court denied defendant's subsequent petition for review.
Held v. Montana
Held that Montana’s policy of excluding greenhouse gas emissions and related climate impacts from environmental reviews of fossil fuel projects violated the state constitution’s guarantee of a clean and healthful environment.
Watson Memorial Spiritual Temple of Christ v. Korban
Ruled that mandamus was an appropriate vehicle for landowners to collect from the city's sewerage and water board inverse-condemnation damages awarded in prior suit
T.F. and B.F. v. Kettle Moraine School District
Trial court held that district's policy of permitting and affirming student requests to transition to a different gender identity at school, without parental consent, violates parents' fundamental due process right to make healthcare decisions for their children. Court relied on expert testimony that living a "double life" with different gender identities at home and at school is "'inherently psychologically unhealthy'" for children.
Singleton v. North Carolina Department of Health and Human Services
A doctor is challenging a law that requires healthcare providers to obtain a “certificate of need” before offering new services or facilities in a geographic area
Stefanik v. Hochul
Upheld New York's universal early mail voting law. The state high court disagreed that a state constitutional clause expressly authorizing absentee voting for specific categories of people should be interpreted to prevent mail-in voting by all others, based on the presumption of constitutionality for state laws, the constitutional history, and another clause allowing the legislature to authorize the "method" of elections.
O’Halloran v. Sec. of State
Michigan Supreme Court held that certain instructions for election challengers and poll watchers issued by the secretary of state in 2022 largely comply with the state’s election law and administrative procedures act, finding only limited statutory violations.
In re Dallas County
Upheld, in a unanimous opinion, a 2023 law creating a new court of appeals that has exclusive statewide jurisdiction over intermediate appeals in most matters brought against the state and challenges to a state law’s constitutionality when the attorney general is a party.
People v. Neilly
Held that defendants who are convicted but have been given reprieve from life-without-parole sentences because their crimes were committed as teenagers can still be required to pay restitution costs.
Johnson v. Wyoming
Plaintiffs claim that abortion ban violates the fundamental right to be left alone by government as guaranteed by several rights enshrined in the state constitution
