Set for argument · November 3, 2026
Pre-decision estimate: 8% cert probability (95% interval 4%–13%)

Before the decision, about 1.9× the 4.1% base rate. The model weighted this up for counsel who has won certiorari before, a petition filed soon after the judgment below, and a Tenth Circuit decision below, and down for a state or local-government respondent.

Questions presented

Granted limited to questions 1 and 2 presented by the petition. Colorado's so-called universal preschool program pays for families to send their children to the preschool of their choice, public or private. To participate, preschools must ensure all families have an "equal opportunity" to enroll regardless of, inter alia, race, religious affiliation, sexual orientation, gender identity, income level, or disability. Colorado nonetheless permits numerous exemptions from this requirement, both categorical and discretionary, allowing preschools to admit only "children of color," "gender-nonconforming children," "the LGBTQ community," low-income families, and children with disabilities. But Colorado excludes Catholic preschools because they admit only families who support Catholic beliefs, including on sex and gender. The Tenth Circuit upheld Colorado's decision to exclude Catholic preschools. Applying Employment Division v. Smith, it held that Colorado's secular exemptions and discretion did not undermine general applicability. In so doing, the court sided with the minority position in an entrenched and acknowledged 7 -4 split over what kinds of exemptions and discretion undermine general applicability. The court also eschewed Carson v. Makin, concluding that its rule was inapplicable because Colorado's exclusion was not "on the explicit basis" of religion. The questions presented are:

  1. Whether proving a lack of general applicability under Employment Division v. Smith requires showing unfettered discretion or categorical exemptions for identical secular conduct.

  2. Whether Carson v. Makin displaces the rule of Employment Division v. Smith only when the government explicitly excludes religious people and institutions.

  3. Whether Employment Division v. Smith should be overruled THE PETITION FOR A WRIT OF CERTIORARI IS GRANTED LIMITED TO QUESTIONS 1 AND 2 PRESENTED BY THE PETITION.
