2026
Rio Grande Foundation v. Oliver
Question Presented

1. Whether New Mexico’s informational interest is sufficient under exacting scrutiny to justify applying its disclosure regime to issue advocacy organizations, like Petitioner, that engage in no express advocacy or its functional equivalent. 2. Whether applying New Mexico’s disclosure regime to an organization that does not meet Buckley’s “major purpose” test and does not engage in express advocacy, like Petitioner, constitutes narrow tailoring under exacting scrutiny absent donor earmarking. 3. Whether disclosure regimes applied to issue advocacy organizations, like Petitioner, that engage exclusively in political speech—without express advocacy or its functional equivalent—must satisfy strict scrutiny rather than exacting scrutiny.

Question Presented

First Choice Women’s Resource Centers, Inc. v. Platkin

2. Whether a state violates the Free Exercise Clause by excluding privately run religious schools from the state’s charter-school program solely because the schools are religious, or whether a state can justify such an exclusion by invoking anti-establishment interests that go further than the Establishment Clause requires.
