Mahmoud v. Taylor (2025)
SCOTUS 2025
Claimant PrevailedSupreme Court held that Maryland parents have a constitutional right to opt their children out of LGBTQ+ inclusive storybook lessons that conflict with their religious beliefs. Public schools must provide notice and opt-out opportunities when curriculum conflicts with sincerely held religious beliefs.
Why it matters: Most significant religious-liberty ruling of 2025. Directly governs curriculum opt-outs in public schools. Also triggered a December 2025 GVR (grant, vacate, remand) sending New York's elimination of religious school-vaccine exemptions back to the Second Circuit for reconsideration in light of this decision.

2d Cir. 2025
Claimant PrevailedSecond Circuit held that sincerity of religious belief is a low bar — courts cannot treat a Title VII accommodation request as insincere merely because the belief is personal, recently formed, or not part of official church doctrine.
Why it matters: Directly relevant to vaccine accommodation claims. Employers cannot reject requests on the grounds that the belief is 'new' or not tied to an organized religion. Widely cited in post-Groff accommodation cases.

7th Cir. 2024
Claimant PrevailedSeventh Circuit confirmed that mixed religious and secular objections still qualify for Title VII religious accommodation. An employee's objection doesn't lose protection merely because it is informed by both religious belief and personal views.
Why it matters: Employers cannot deny accommodation by arguing that an objection is 'really' secular. Courts look at whether religion is a sincere factor, not whether it's the only factor. Persuasive authority in all circuits.

600 U.S. 447
Claimant PrevailedUnanimous decision strengthening Title VII workplace religious accommodation. Employers must show substantial increased costs to deny accommodation — not merely more than a de minimis burden.
Why it matters: Most consequential workplace religious-liberty ruling in 46 years. Overturned the prior 'de minimis' standard that allowed employers to deny accommodation for almost any reason. Directly applies to vaccine mandate exemption cases.

600 U.S. 570
Claimant PrevailedWeb designer cannot be forced by state anti-discrimination law to create websites celebrating same-sex marriages. Compelled speech violates the First Amendment.
Why it matters: Strong free speech and religious liberty protection for creative professionals. Government cannot compel expressive conduct that conflicts with sincerely held beliefs.
Read full opinion →Fulton v. City of Philadelphia (2021)
593 U.S. 522
Narrow RulingCatholic Social Services won the right to continue foster care ministry despite the city's anti-discrimination policy. Decided on narrow grounds — the city's contract included discretionary exemptions, making the policy not 'generally applicable' under Smith.
Why it matters: Cities and states that build exemption discretion into their policies must also accommodate religious exemptions. Deliberately narrow — did not overturn Employment Division v. Smith, but left Smith's limits under open question.

593 U.S. ___ (2021)
Claimant PrevailedCalifornia's COVID restrictions on home religious gatherings struck down. Government cannot treat comparable secular activities more favorably than religious ones.
Why it matters: Important post-COVID precedent establishing that any secular comparator triggers strict scrutiny. Government must apply restrictions equally to secular and religious activities.
Read full opinion →Masterpiece Cakeshop v. Colorado (2018)
584 U.S. 617
Narrow RulingBaker who declined to make a same-sex wedding cake won on deliberately narrow grounds — the Colorado Civil Rights Commission showed demonstrable hostility toward his religious beliefs. The Court did not resolve the broader free-speech vs. anti-discrimination question.
Why it matters: Government bodies cannot treat religious objectors with hostility or disparate treatment. The narrow holding means this case's protections depend on demonstrating official hostility — not a general exemption rule.

573 U.S. 682
Claimant PrevailedClosely held corporations cannot be forced to provide contraceptive coverage that violates owners' religious beliefs. RFRA protections extend to for-profit businesses.
Why it matters: Expanded RFRA protection to business owners with sincere religious beliefs. Confirmed that government must use the least restrictive means when burdening religious exercise.
Read full opinion →Gonzales v. O Centro Espírita (2006)
546 U.S. 418
Claimant PrevailedUnanimous decision. Religious group won the right to use hoasca tea in ceremonies despite federal drug law. Government could not show a compelling interest sufficient to override RFRA.
Why it matters: Demonstrated that RFRA has real practical force. Government must make a specific, not generalized, showing of compelling interest when burdening a particular religious practice.

508 U.S. 520
Claimant PrevailedCity ordinance banning animal sacrifice was struck down as targeting religion. Laws that are not neutral and generally applicable — but instead target specific religious practices — face strict scrutiny.
Why it matters: Key limit on Employment Division v. Smith. Laws that are facially neutral but demonstrably targeted at religion are still subject to the compelling interest test.
Read full opinion →Employment Division v. Smith (1990)
494 U.S. 872
Rights LimitedCourt held that neutral, generally applicable laws do not require religious exemptions even if they substantially burden religious practice. Sharply curtailed the pre-existing Sherbert compelling-interest test for most laws.
Why it matters: Controversial and heavily criticized decision that prompted Congress to pass RFRA in 1993 and many states to pass state RFRAs. Still controlling for neutral, generally applicable laws — but Fulton, Tandon, and Lukumi have carved significant exceptions.

406 U.S. 205
Claimant PrevailedAmish families won the right to remove children from school after 8th grade. Supreme Court held that parental religious rights, combined with the Amish community's specific circumstances, outweighed the state's compulsory education interest.
Why it matters: Landmark precedent for parental rights and religious education exemptions. Establishes that the government's interest in education must be balanced against deeply held parental religious convictions. Still widely cited.

374 U.S. 398
Claimant PrevailedEstablished the original 'compelling interest' test — government must show a compelling interest and use the least restrictive means before burdening religious practice. Applied to a Seventh-day Adventist denied unemployment benefits for refusing Saturday work.
Why it matters: Foundation of modern religious freedom law for 27 years until Smith (1990) narrowed its application. Remains the standard under RFRA and state equivalents, and is the framework courts apply when Smith doesn't shield the government.
