Featured Cases
Commonwealth v. Lee
The Pennsylvania Supreme Court held that mandating a life sentence, without the possibility of parole, for “felony murder” — a legal doctrine that allows someone to be prosecuted for murder for any death that occurs during the commission of a separate felony, even if the defendant never meant to kill anyone — violates the Pennsylvania Constitution’s ban on “cruel” punishments
Luther v. Hoskins
The Missouri Supreme Court rejected voters' challenge to Missouri's new congressional district map, which the plaintiffs said ran afoul of state constitutional prohibitions on mid-decade redistricting. The court said the state constitution contained no express prohibition on mid-decade redistricting and that the map was a "valid exercise" of the "plenary legislative power to establish congressional districts."
League of Women Voters of Missouri v. State
The Missouri Supreme Court permanently enjoined criminal penalties for third-party voter registration and voter-engagement activities, upholding a lower court decision that the restrictions were unconstitutionally vague and violated free speech and association rights
Mills v. Arizona State Board of Technical Registration
Electrical engineer Greg Mills challenges Arizona's licensing requirement for certain engineers as violating his right to earn a living under the state’s due process clause and running afoul of the privileges or immunities clause (the state’s equivalent of equal protection), among other claims
Lawyers for Children v. New York State Office of Children
New York Court of Appeals will consider whether a state agency acted without legislative authorization when it created a new system temporarily placing children, whose parents voluntarily seek outside care, in "host homes"
Gamble v. State

In the Matter of Request for Opinion of the Justices
Maine Supreme Court will consider legislature's request for an advisory opinion on the state constitutionality of extending ranked-choice voting to the general elections for governor and the state legislature
Williams v. Board of Elections of the State of New York
New York trial court held that the state’s 11th congressional district violated a 2014 state constitutional amendment barring racial vote dilution and ordered the state’s congressional map redrawn. The U.S. Supreme Court stayed the trial court’s order pending the disposition of the appeal in the New York state courts and any petition for certiorari in the Supreme Court. The state case was subsequently dismissed on the agreement of the parties.
Koski v. RNC
Virginia Supreme Court permitted legislature’s proposed amendment to redraw the state’s congressional map to proceed to a vote, staying trial court's temporary restraining order against officials moving forward with the election
Luther v. Hoskins
The Missouri Supreme Court rejected voters' challenge to Missouri's new congressional district map, which the plaintiffs said ran afoul of state constitutional prohibitions on mid-decade redistricting. The court said the state constitution contained no express prohibition on mid-decade redistricting and that the map was a "valid exercise" of the "plenary legislative power to establish congressional districts."
