Featured Cases
League of Women Voters of South Carolina v. Alexander
South Carolina Supreme Court held that partisan gerrymandering claims are nonjusticiable political questions, which state courts cannot review, under the state constitution.
League of Women Voters of Utah v. Utah State Legislature (LWV 1)
Utah Supreme Court sent partisan gerrymandering case back to lower court to consider whether the legislature violated voters' fundamental right to "reform or alter" their government when it overturned redistricting reforms passed by initiative. Lower court found legislators violated that right and struck the current congressional map.
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.
Attorney General v. Hood
Held that the state’s civil rights charges against the Nationalist Social Club-131, a white nationalist and neo-Nazi organization operating in the New England area, in connection with a July 2022 incident where members displayed banners reading “KEEP NEW ENGLAND WHITE” from a highway overpass without a permit, impermissibly chilled the defendant’s constitutional right of free speech and premised on an overbroad reading of the statute
Montana Environmental Information Center & Sierra Club v. Montana Department of Environmental Quality
Held that the Department of Environmental Quality appropriately considered noise impacts of a proposed project as required under the Montana Environmental Policy Act, but did not analyze lighting impacts and greenhouse gas emissions as required under the then-applicable language of the Act
Montana Trout Unlimited v. Montana Department of Natural Resources & Conservation
Held that the exemption of dewatering from the Montana Water Use Act's permitting requirements did not violate the water rights section of the state's constitution
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.
Department of Environmental Protection v. Pennsylvania Legislative Reference Bureau; Bowfin KeyCon Holdings v. Pennsylvania Department of Environmental Protection
The Pennsylvania Supreme Court will consider consolidated challenges to the state's participation in a regional program to cap greenhouse gases. The Commonwealth Court found the program to constitute a tax within the prerogative of the legislature, so concluded the governor's entry into the program by executive rulemaking violated separation of powers. Amicus groups and intervenors have argued the lower court's tax determination did not adequately take account of the state's duties under Pennsylvania's environmental rights amendment.
Krasner v. Sunday
The Pennsylvania Supreme Court will consider the Philadelphia district attorney's challenge to a law that requires the state attorney general to appoint a special prosecutor to have jurisdiction over crimes committed within the regional public transit system. The Commonwealth Court rejected the allegations, including that the law unconstitutionally divests the district attorney of jurisdiction over part of the office’s territory, nullifies the district attorney’s core prosecutorial functions, and violates the due process rights of defendants based on a provision preventing those charged by the special prosecutor from challenging his authority.
Gotay v. Creen
Massachusetts Supreme Judicial Court held that a “special relationship” exists between foster children and the state that imposes an affirmative duty on the state to ensure a reasonably safe foster home environment, but found the state defendants were entitled to qualified immunity on the parent and guardian's substantive due process claim.
Dupuis v. Roman Catholic Bishop of Portland
Held that a law that revived claims based on sex acts toward minors that were previously time-barred impairs a defendant's vested right to be free from a claim once its statute of limitations has expired, finding that a prohibition on laws reviving expired claims "runs as a theme" throughout the text of Maine's Constitution.
State v. Francisco Edgar Tirado
Held that North Carolina's "cruel or unusual" punishment clause — construed consistently with a separate state constitutional provision specifying the types of punishment laws may impose, without limitations based on age — would provide less protection against life-without-parole sentences for juveniles than the Eighth Amendment, so must be interpreted in lockstep with the federal "cruel and unusual" punishment clause.
State of Washington v. Gator's Custom Guns
Washington Supreme Court reversed a lower court and upheld under the state and federal right to bear arms the state's ban on selling or manufacturing magazines that hold more than ten rounds of ammunition.
