Holt v. Hobbs
The Supreme Court ruled unanimously that Arkansas prison officials violated a federal law protecting inmates' religious practices by refusing to let a Muslim prisoner grow a half-inch beard.
The decision makes clear that prisons cannot simply assert security concerns to justify restricting religious practice; they must prove they have no less restrictive way to address those concerns, giving inmates nationwide stronger tools to challenge grooming and other religious restrictions.
“And without a degree of deference that is tantamount to unquestioning acceptance, it is hard to swallow the argument that denying petitioner a ½-inch beard actually furthers the Department's interest in rooting out contraband.”
The Court's skepticism toward the prison's contraband justification for banning the beard.
How it got here: A magistrate judge recommended dismissing Holt's suit, the district court agreed, and the Eighth Circuit affirmed, deferring to prison officials' security judgment.
The Case in Depth
What happened
Gregory Holt, an Arkansas inmate and devout Muslim, asked prison officials for permission to grow a half-inch beard as required by his faith. The Arkansas Department of Correction's grooming policy banned beards except for inmates with diagnosed skin conditions, who could grow quarter-inch beards. Prison officials denied Holt's request and warned him he would face discipline if he grew a beard anyway, so he sued.
The question before the Court
Could an Arkansas prison stop a Muslim inmate from growing a half-inch beard for religious reasons by citing security concerns about contraband and prisoner identification?
The Court's answer
No — the Supreme Court ruled that Arkansas could not enforce its no-beard policy against Holt, because the prison failed to prove that banning his half-inch beard was the least restrictive way to protect its security interests. The Department's worries about hidden contraband and disguised identities were not enough on their own; RLUIPA demands real proof that no less-restrictive option, like searching the beard or photographing inmates with and without facial hair, would work just as well.
The Court also found the policy inconsistent, since it already allowed quarter-inch beards for medical reasons and unlimited head hair, undercutting the claim that a half-inch beard posed a unique risk. Because most other prison systems safely allow such beards, Arkansas needed—but failed to offer—persuasive reasons why it could not do the same.

Why it matters
Prisoners across the country who seek religious accommodations—beards, head coverings, dietary practices—now have a clearer, tougher standard prison officials must meet before denying those requests. Prisons must show real evidence, not just generalized security worries, and point to why less restrictive options (like searches or photographs) will not work.
What changes now
The case is sent back to the lower courts, but the Supreme Court's ruling resolves the merits: Arkansas's grooming policy cannot be enforced against Holt in a way that stops him from growing his half-inch beard. Prison officials remain free to search the beard, photograph inmates, or otherwise verify security, and the Court noted institutions retain tools to police against insincere or abused religious claims going forward.
What this does not decide
The Court did not rule that prisons can never regulate beards or grooming, and it left prisons free to search beards, require photographs, question the sincerity of a claimed religious belief, or withdraw an accommodation later if abused. The ruling is limited to this specific policy as applied to this inmate's half-inch beard request.
Concurrences and dissents
Concurrence — Justice Ginsburg
Justice Ginsburg, joined by Justice Sotomayor, wrote separately to distinguish this case from Burwell v. Hobby Lobby. She emphasized that letting Holt grow his beard, unlike the contraceptive exemption in Hobby Lobby, would not harm any third parties who do not share his religious belief, and joined the Court's opinion on that understanding.
Concurrence — Justice Sotomayor
Justice Sotomayor wrote separately to clarify the legal standard, stressing that deference to prison officials remains appropriate when they offer a plausible, evidence-based explanation, but not when they merely assert a compelling interest by fiat. She emphasized that the Department's fatal problem was its failure to explain why the specific less-restrictive alternatives Holt identified during litigation were inadequate.
How the Court got there
The legal reasoning, step by step
- Under the federal Religious Land Use and Institutionalized Persons Act (RLUIPA), an inmate must first show the challenged rule substantially burdens a sincerely held religious practice; the Court found this easily met because Holt faced discipline for following his faith's beard requirement.
- The Court rejected the lower courts' reasoning that the burden was lessened because Holt could practice his religion in other ways (prayer, diet, holidays), explaining that RLUIPA looks only at whether the specific practice at issue is burdened, not whether substitutes exist.
- Once a substantial burden is shown, the burden shifts to the government to prove its policy is the least restrictive means of furthering a compelling interest, applied specifically to this inmate rather than to a broadly stated interest in general prison security.
- Applying that demanding standard, the Court found the prison's contraband-hiding justification unconvincing for a half-inch beard, especially since guards already search hair, clothing, and quarter-inch medical beards without incident.
- The Court likewise found the prison's identification-disguise justification insufficient, noting that photographing inmates with and without beards—a method other prisons already use—addressed the concern without banning the beard entirely.
- The Court also found the policy inconsistently applied: it allowed quarter-inch beards for medical reasons and unlimited head hair length, undermining the claim that a half-inch beard posed an unacceptable security risk, and noted that most other prison systems allow such beards without issue.
