Michigan Supreme Court
Mar 2026
Civil Liberties
People v. Jennings
This case asks whether Michigan should adopt an approach to state constitutional interpretation that prioritizes Michigan sources and does not automatically require reference to parallel federal provisions or interpretations. The outcome of this case could have significant implications for the constitutional rights of Michiganders because an interpretation of the Michigan Constitution untethered from federal precedent provides an independent, and potentially more expansive, layer of security for individual rights.

Kansas Supreme Court

LGBTQ Rights
Kansas v. Harper
Five transgender Kansans are challenging an effort by Kansas Attorney General Kobach to require the state to issue driver’s licenses with a gender marker that reveals their sex assigned at birth. The Attorney General is asking a state court to apply a new state law that defines “sex” to functionally erase the existence of transgender people under the law.

New Mexico Supreme Court

Atencio v. State of New Mexico
This case asks whether the State of New Mexico’s actions enabling pollution from oil and gas extraction, and its failure to control that pollution, violate the New Mexico Constitution’s Pollution Control Clause, Inherent Rights Clause, Due Process Clause, and Equal Protection Clause. Our brief urges the New Mexico Supreme Court to answer those questions by retiring its “interstitial approach” to state constitutional interpretation—which looks first to federal doctrine when interpreting state constitutional provisions that arguably have U.S. Constitutional analogues—and instead interpreting the New Mexico Constitution holistically and independently. This independent approach, we explain, will ensure that New Mexicans can enjoy—and enforce—the rights guaranteed to them in their unique founding document.

Iowa Supreme Court

Racial Justice
In re Ezra L. Totton Scholarship
This case asks whether, in the wake of the U.S. Supreme Court’s holding in Students for Fair Admissions, Inc. v. Harvard College, a university may refuse to administer a privately funded scholarship set aside for Black students majoring in the physical sciences and redirect those funds to first-generation students instead. The district court denied the University’s petition to do so, and the case is now on appeal before the Iowa Supreme Court. The Court’s decision could have significant implications for other private scholarships that address the lasting effects of segregation.

New Mexico Supreme Court
Jan 2026
Prisoners' Rights
Franklin v. Martinez
This case raises the question whether New Mexico courts should retire their current, federal-centric approach to interpreting the New Mexico Constitution—a method known as the “interstitial approach”—and embrace an independent approach that would allow them to more readily diverge from federal courts in light of New Mexico’s own law, history, and values. The Court’s decision could have major implications for New Mexicans’ ability to vindicate their state constitutional rights.
