Featured Cases
LeMieux v. Evers
The Wisconsin Supreme Court will address the scope of Gov. Tony Evers’s state constitutional authority to approve spending bills passed by the legislature only “in part,” by line-item vetoing other parts.
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.
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.

Held that federal railroad law did not preempt state constitution’s requirement for tax uniformity, ruled taxing commission may not tax railroad properties differently than plaintiffs’ properties
