Featured Cases
LeMieux v. Evers
The Wisconsin Supreme Court held, in a divided decision, that the governor did not exceed his partial veto authority under the state constitution when he altered digits, words, and punctuation in a budget bill to extend a school funding increase from 2 to 402 years.
Griffin v. State Board of Elections
A candidate for a seat on the North Carolina Supreme Court, who lost by over 700 votes, claims that the state board of elections followed an incorrect process for registering voters and seeks in invalidate more than 60,000 votes.
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.
Tatum v. Commissioner of Corrections
Held that a new constitutional rule of criminal procedure applies retroactively under certain conditions and principles regarding the admissibility of eyewitness identification evidence apply retroactively
State v. Diole
Held that subjecting incompetent defendants to a determination of whether they committed the acts charged without a jury trial, the protections of medical privilege, and the safeguards of the rules of evidence did not violate due process and equal protection
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.
Planned Parenthood of Montana v. State of Montana (Planned Parenthood 2)
Ruled that minors have a fundamental right to privacy and do not have to seek parental permission to get an abortion in the state.
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
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
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
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.
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.
