Founding-Era “Religious Establishment” Hallmarks Govern Ten Commandments Classroom Displays (Stone v. Graham Treated as Defunct After Lemon’s Abandonment)

Case: Nathan v. Alamo Heights Independent School District (5th Cir. Apr. 21, 2026) (en banc, initial) | Author: Duncan, J. | Disposition: Reversed; preliminary injunction vacated; claims dismissed

I. Introduction

Nathan addresses Texas S.B. 10, codified at Tex. Educ. Code Ann. § 1.0041, which requires public elementary and secondary schools to display a “durable poster or framed copy of the Ten Commandments” in each classroom, with statutorily mandated dimensions, conspicuous placement, and a single prescribed text (“include only” the quoted Commandments). Plaintiffs—Texas parents and their minor children of varied religious backgrounds— sued multiple school districts, contending the law (1) constitutes an “establishment of religion” and (2) burdens religious exercise by coercing children to “reverence” the Commandments and undermining parental rights.

The district court enjoined S.B. 10, relying heavily on the Fifth Circuit’s then-operative panel decision in a similar Louisiana dispute, Roake v. Brumley (Roake Panel), 141 F.4th 614 (5th Cir.), vacated, 154 F.4th 329 (5th Cir. 2025) (mem.). While the Fifth Circuit later dismissed the Louisiana case as unripe, Roake v. Brumley (Roake En Banc), 170 F.4th 292 (5th Cir. 2026) (en banc) (per curiam), it held the Texas case was ripe because S.B. 10 fixes the display’s content, size, and conspicuous placement statewide, leaving no local discretion that would require further factual development.

The central legal question was how to evaluate classroom Ten Commandments displays after the Supreme Court’s rejection of the Lemon framework and its “endorsement” offshoot, particularly in light of Kennedy v. Bremerton Sch. Dist., 597 U.S. 507 (2022), and the Court’s more recent free-exercise parental-rights decision, Mahmoud v. Taylor, 606 U.S. 522 (2025).

II. Summary of the Opinion

The en banc majority reversed and ordered dismissal of both the Establishment Clause and Free Exercise Clause claims. Key holdings:

Establishment Clause: Stone v. Graham, 449 U.S. 39 (1980) (per curiam), is not controlling because it relied entirely on the Lemon v. Kurtzman, 403 U.S. 602 (1971), test—especially the “secular purpose” prong—and the Supreme Court has “abandoned” and “abrogated” Lemon. The controlling inquiry after Kennedy is whether the challenged law bears the hallmarks of a founding-era “establishment of religion.” S.B. 10 does not resemble a founding-era establishment and does not coerce religious worship or formal religious exercise.
Free Exercise Clause: Plaintiffs failed to show S.B. 10 “substantially burdens” religious exercise. Unlike Mahmoud, S.B. 10 does not create a compulsory curriculum designed to “disrupt” beliefs, does not authorize teacher-led religious instruction, does not compel affirmation or recitation, and does not direct teachers to contradict or stigmatize students’ beliefs. A “poster on a classroom wall” is not comparable to a program of coercive indoctrination.
Justiciability: Plaintiffs had standing on a “direct harm”/coercion theory, and the case was ripe because S.B. 10 mandates uniform display details statewide (unlike the Louisiana statute that delegated key details to local authorities).

III. Analysis

A. Precedents Cited (and How They Shaped the Decision)

1. The fall of Lemon and the majority’s treatment of Stone

Lemon v. Kurtzman, 403 U.S. 602 (1971): The majority recited Lemon’s three-part test (purpose, effect, entanglement) and emphasized that it “confounded courts for decades.” It treated Kennedy v. Bremerton Sch. Dist., 597 U.S. at 534, as the decisive statement that the Court has “abandoned Lemon,” with Groff v. DeJoy, 600 U.S. 447, 460 (2023), confirming Lemon was “abrogated.” The Fifth Circuit’s own Freedom from Religion Found., Inc. v. Mack, 49 F.4th 941, 954 n.20 (5th Cir. 2022), was cited to declare Lemon’s “Night of the Living Dead” over.
Stone v. Graham, 449 U.S. 39 (1980) (per curiam): Plaintiffs and the district court treated Stone as binding because it invalidated a similar Ten Commandments classroom-posting law. The majority rejected that framing by reading Stone as “Lemon all the way down”: Stone quoted Lemon’s test, applied the “secular purpose” prong, and expressly concluded Kentucky’s law “violates the first part of the Lemon” test. With Lemon removed, the majority held “there is nothing left of Stone.”
Rodriguez de Quijas v. Shearson/Am. Express, Inc., 490 U.S. 477 (1989): Plaintiffs invoked the rule that lower courts must follow Supreme Court precedent until the Supreme Court overrules it. The majority distinguished this by characterizing Stone not merely as “in tension” with later cases but as part of Lemon’s abrogated “progeny.”
McCreary County v. ACLU, 545 U.S. 844 (2005) and Van Orden v. Perry, 545 U.S. 677 (2005): Plaintiffs argued these 2005 cases “reaffirmed” Stone. The majority responded that both predated Kennedy and therefore do not prevent the conclusion that Lemon’s later abandonment drains Stone of operative reasoning.

2. Kennedy’s historical framework and the “hallmarks” approach

Kennedy v. Bremerton Sch. Dist., 597 U.S. 507 (2022): The majority treated Kennedy as announcing the governing Establishment Clause method: interpret “by reference to historical practices and understandings” and ask whether the challenged action bears “hallmarks of religious establishments,” especially coercion to attend church or engage in “formal religious exercise.” This replaced Lemon’s purpose/effect/entanglement inquiries.
Town of Greece v. Galloway, 572 U.S. 565 (2014) and Marsh v. Chambers, 463 U.S. 783 (1983): Used to illustrate the Court’s modern history-and-tradition approach (particularly in legislative prayer). The majority rejected Plaintiffs’ attempt to convert those cases into a requirement that the challenged practice itself have a founding-era “tradition” (e.g., Ten Commandments in public-school classrooms) to be constitutional; instead, the question is whether the practice resembles a founding-era establishment.
Shurtleff v. City of Boston, 596 U.S. 243 (2022) (Gorsuch, J., concurring in the judgment): Cited (via Kennedy) as discussing historical “hallmarks” of establishment.
Hilsenrath ex rel. C.H. v. Sch. Dist. of Chathams, 136 F.4th 484 (3d Cir. 2025) and Firewalker-Fields v. Lee, 58 F.4th 104 (4th Cir. 2023): The majority cited these circuits as distilling Kennedy into the question whether plaintiffs have shown facts “historically understood as an establishment of religion.”

3. School coercion and the majority’s narrower conception of “coercion” under Establishment

Lee v. Weisman, 505 U.S. 577 (1992) and Zorach v. Clauson, 343 U.S. 306 (1952): Used in Kennedy (and here) to describe establishment-like coercion as pressure to attend church or engage in formal religious exercise. The majority framed S.B. 10 as not compelling worship, prayer, recitation, or teacher-led devotion.
Engel v. Vitale, 370 U.S. 421 (1962) and Sch. Dist. of Abington Twp. v. Schempp, 374 U.S. 203 (1963): These appear primarily in the justiciability discussion (standing via coercion analogy) and as background to Establishment Clause disputes. The majority emphasized that S.B. 10 does not impose prayer or devotional reading.

4. Free exercise, parental rights, and compelled affirmation

Mahmoud v. Taylor, 606 U.S. 522 (2025): The centerpiece of the Free Exercise analysis. The majority distinguished Mahmoud’s compulsory curriculum designed to “disrupt” beliefs, teacher training to correct/stigmatize children’s views, and lack of opt-outs. S.B. 10, by contrast, was characterized as “exposure” without compelled affirmation, instruction, or correction.
Wisconsin v. Yoder, 406 U.S. 205 (1972) and Pierce v. Soc’y of Sisters, 268 U.S. 510 (1925): Cited for the principle that parents may challenge state action that substantially interferes with children’s religious development and parental direction; the majority held no such “substantial burden” was plausibly shown here.
W. Va. State Bd. of Educ. v. Barnette, 319 U.S. 624 (1943): Used to contrast truly compelled speech/affirmation with S.B. 10’s passive posting; the majority emphasized no child is required to recite, believe, or affirm the Commandments.

5. Standing, ripeness, and the “offended observer” debate

Steel Co. v. Citizens for a Better Env’t, 523 U.S. 83 (1998): Cited for the appellate duty to ensure jurisdiction.
Susan B. Anthony List v. Driehaus, 573 U.S. 149 (2014) (quoted in Mahmoud): For pre-enforcement standing, injury must be “certainly impending” or pose a “substantial risk.”
TransUnion LLC v. Ramirez, 594 U.S. 413 (2021): For the “standing is not dispensed in gross” principle.
Braidwood Mgmt. v. EEOC, 70 F.4th 914 (5th Cir. 2023) and Opulent Life Church v. City of Holly Springs, 697 F.3d 279 (5th Cir. 2012): For ripeness (fitness and hardship). The majority held S.B. 10 presents a “pure question of law” because it mandates the content and conspicuous placement, unlike the Louisiana statute discussed in Roake En Banc.
Roake v. Brumley (Roake En Banc), 170 F.4th 292 (5th Cir. 2026): The en banc Fifth Circuit found Louisiana’s case unripe because key display details were left to local authorities; Nathan relied on statutory differences to find ripeness here.

6. Denominational preference

Cath. Charities Bureau Inc. v. Wis. Lab. & Indus. Rev. Comm’n, 605 U.S. 238 (2025) and Larson v. Valente, 456 U.S. 228 (1982): The majority recognized the rule against denominational favoritism in the context of burdens/benefits but concluded it does not sensibly apply to government “use of religious language or symbolism,” and it refused to adjudicate intra-faith disputes about which “version” of the Decalogue S.B. 10 reflects.
Presbyterian Church in U.S. v. Mary Elizabeth Blue Hall Mem’l Presbyterian Church, 393 U.S. 440 (1969), Watson v. Jones, 80 U.S. (13 Wall.) 679 (1871), and Thomas v. Rev. Bd. of Ind. Emp. Sec. Div., 450 U.S. 707 (1981): Cited to justify judicial non-involvement in doctrinal disputes and “scriptural interpretation.”

7. Experts and “outsourcing” constitutional meaning

Goodman v. Harris County, 571 F.3d 388 (5th Cir. 2009): Used to reject expert testimony that “render[s] conclusions of law.”
Marbury v. Madison, 5 U.S. (1 Cranch) 137 (1803): Invoked for the court’s duty to decide legal questions rather than defer to experts.
The majority also drew on the opinion’s discussion distinguishing “adjudicative facts” (trial facts) from “legislative facts” (history, social facts) and emphasized constitutional meaning cannot be insulated by clear-error review through “expert findings.”

B. Legal Reasoning

1. Establishment Clause: from Lemon’s “purpose” to founding-era “establishments”

The majority’s doctrinal pivot is categorical: the “secular purpose” inquiry—central to the district court’s injunction—was treated as a Lemon artifact. Because Kennedy declares Lemon abandoned, and because Stone expressly rested on Lemon’s first prong, the majority concluded Stone can no longer bind lower courts.

In Lemon’s place, the court applied a historically anchored question: whether S.B. 10 resembles an “establishment of religion” as the founding generation understood that term. The court devoted substantial attention to the historical “institution” of establishment (e.g., the Church of England and colonial/state establishments) and distilled commonly recurring “elements”: compelled church attendance; state control of doctrine/worship/governance; punishment of dissenters; religious taxes; using churches for civil functions; and restricting political participation.

Against that template, the court held S.B. 10 “looks nothing like” an establishment: no regulation of churches, clergy, or doctrine; no sanctions for dissent; no compelled support of clergy; no conscription of church institutions; and, crucially, no compulsion to engage in worship or formal religious exercise. The “coercion” Plaintiffs alleged was characterized as mere exposure to a wall poster, not pressure to pray, attend worship, or participate in devotional acts.

2. Free Exercise Clause: substantial burden and the Mahmoud comparator

The majority treated Mahmoud as a high-water mark of unconstitutional curricular coercion: teacher-led, compulsory messaging designed to disrupt and stigmatize religiously grounded beliefs, with no opt-outs. It then framed S.B. 10 as the opposite: no prescribed instruction, no teacher scripts, no correction of student beliefs, and no compelled affirmation (distinguishing Barnette).

Plaintiffs’ theory—that mere exposure to religious language is itself a substantial free-exercise burden—was rejected as inconsistent with the nature of the coercion found in Mahmoud and as potentially destabilizing (the opinion tested the theory with examples raised at argument, including classroom display of the Declaration of Independence and Lincoln’s Second Inaugural). The court also emphasized remedy: Plaintiffs sought wholesale removal of the display, whereas Mahmoud and Barnette were described as allowing opt-outs rather than “micromanage[ment]” of curricula or classroom environments.

3. Justiciability reasoning as a doctrinal signal

Although several concurrences expressed skepticism about standing (and about “offended observer” theories), the majority found standing on a “direct harm” theory tied to students’ mandatory school attendance and likely/inevitable encounter with the mandated display (Lee v. Weisman was cited for the likelihood of encounter in the school setting). Ripeness turned on statutory determinacy: Texas’s law fixed all relevant display attributes, unlike Louisiana’s more discretionary scheme rejected as unripe in Roake En Banc.

C. Impact

1. Establishment Clause litigation: Stone-era classroom display suits in the Fifth Circuit

The most immediate impact is the Fifth Circuit’s explicit conclusion that Stone v. Graham has no operative force after Lemon’s abandonment. Within the circuit, that sharply narrows a previously straightforward path to enjoining Ten Commandments classroom mandates.

2. The operative test: “founding-era establishment” resemblance, not secular purpose or endorsement

Nathan operationalizes Kennedy as a “hallmarks” inquiry focused on the institutional features of historical establishments—especially coercion understood as compelled worship or formal religious exercise. Future Establishment Clause plaintiffs in the Fifth Circuit can expect:

Less emphasis on legislative motive/secular purpose; more on historical analogy.
Coercion arguments to be framed in terms of compelled worship/participation rather than exposure or offense.
Heavy historical briefing about what counted as “establishment” at the founding, including state constitutional disestablishment provisions.

3. Free Exercise in schools after Mahmoud: “exposure” vs “deployment”

The opinion draws a strong line between (a) teacher-deployed curricula designed to disrupt/stigmatize beliefs (Mahmoud) and (b) passive or non-instructional exposure to religious text. That distinction will likely matter in future disputes over classroom posters, readings, library materials, or other ambient educational content—particularly where plaintiffs cannot allege teacher-enforced conformity.

4. Procedure: ripeness turns on statutory specificity

The comparison to Roake En Banc signals a drafting lesson: statewide laws that fix content, size, and conspicuous placement can be “fit” for facial, pre-enforcement review; laws delegating meaningful context-setting discretion to local actors may trigger ripeness dismissals.

5. Evidence and methodology: skepticism toward “expert” legal-history findings

Nathan also telegraphs a methodological preference: judges may consult scholarship, but the court disapproved using experts to generate “findings” on original meaning insulated by clear-error review. That stance may affect how district courts build records in religion-clause cases post-Kennedy.

IV. Complex Concepts Simplified

“Lemon test”: A former three-part Establishment Clause test (secular purpose; primary effect; excessive entanglement). The majority reads Kennedy and Groff as ending Lemon’s use in Establishment cases.
“Stone is an empty vessel” (as used here): Because Stone v. Graham explicitly relied on Lemon’s “secular purpose” prong, the majority reasoned that once Lemon is “abrogated,” Stone’s reasoning has nothing left to operate on.
Founding-era “establishment of religion”: Not just “government action involving religion,” but a legal institution—often an official church— maintained through compulsion (attendance/taxes), punishment of dissent, control of doctrine and church governance, and civil privileges tied to membership.
Coercion (Establishment context): For the majority, coercion means government pressure to participate in worship/formal religious exercise (e.g., prayer/attendance), not the psychological or social pressure that might arise from exposure to religious text.
Free Exercise “substantial burden”: Government action that significantly interferes with religious practice/belief or parental direction of a child’s religious upbringing; the majority held a mandated poster without required instruction is not enough.
Standing / ripeness (pre-enforcement facial challenge): Standing asks whether plaintiffs face a sufficiently imminent, concrete injury; ripeness asks whether the dispute is ready for decision without contingent facts. The court found both satisfied because the statute mandates a uniform, conspicuous, unavoidable display in classrooms children must attend.
Adjudicative vs legislative facts: Adjudicative facts are case-specific “who did what” facts; legislative facts are broad background facts (history, social context) used to decide constitutional meaning. The majority treated founding-era meaning as a legal question, not something to be “found” by expert witnesses.

V. Conclusion

Nathan v. Alamo Heights ISD is the Fifth Circuit’s most consequential post-Kennedy Establishment Clause decision on religious classroom displays. It announces, for this circuit, that Stone v. Graham cannot control because Stone was a Lemon-purpose decision and Lemon has been abandoned/abrogated. In its place, the court applies a founding-era “religious establishment” hallmarks inquiry and holds a mandated Ten Commandments poster—without compelled prayer, instruction, or sanctions—does not resemble an establishment and does not substantially burden free exercise under Mahmoud, Yoder, and related cases.

The decision thus narrows Establishment Clause challenges to passive religious displays in schools (as framed by the majority), raises the evidentiary and historical burdens on plaintiffs, and signals a procedural roadmap in which statutory specificity can make classroom-display mandates ripe for facial review, even as the underlying merits analysis turns on whether the state action compels worship or formal religious exercise.
