Appellate Courts Split on Legal Challenges to
State Laws Banning Certain Medical
Treatments for Transgender Minors
Updated April 4, 2024
Public debate and attention has focused on whether certain medical treatments should be available for
transgender minors to address a discordance between a person’s sex characteristics and gender identity. A
number of states have passed laws prohibiting specific treatments for minors, including puberty blocking
medication (“puberty blockers”), hormones, and surgical procedures. Several states assert, among other
things, that the treatments are too experimental and can have potentially irreversible effects. Parents of
transgender minors, among others, argue that these laws deny critical medical care to transgender minors
and discriminate based on sex or transgender status in violation of the Equal Protection Clause of the
Fourteenth Amendment. Some litigation has also alleged that these laws violate state constitutions.
In cases challenging the laws of Arkansas, Alabama, Tennessee, Kentucky, Indiana, and Idaho, plaintiffs
sought federal court orders to preliminarily enjoin these states from enforcing the laws until final
resolution of the cases. Several lower courts granted these preliminary injunctions, in part based on the
conclusion that the plaintiffs were likely to succeed on the merits of their equal protection claims. Three
federal courts of appeals analyzed whether the lower courts had erred in their rulings and issued opinions
reaching different conclusions. The Eighth Circuit upheld a preliminary injunction of Arkansas’s law,
while the Eleventh Circuit held that a district court erred in enjoining the Alabama law, and the Sixth
Circuit reversed preliminary injunctions that were issued against the Kentucky and Tennessee laws. Two
other appellate courts reviewed preliminary injunctions and issued orders without accompanying opinions
as of yet. The Seventh Circuit, after hearing oral argument, issued a stay of the lower court’s preliminary
injunction against application of Indiana’s law, meaning that the law can go into effect while the case
proceeds. By contrast, the Ninth Circuit denied a motion to stay a preliminary injunction against Idaho’s
law, meaning that that law may not be enforced for now.
This Sidebar focuses on aspects of the appellate court opinions addressing whether plaintiffs are likely to
prevail on their claims that the laws violate the Equal Protection Clause. The three courts that have issued
opinions reached different conclusions on at least two important legal questions relevant to the issue: (1)
whether the challenged laws amount to sex classifications within the meaning of the Equal Protection
Clause, and (2) what standard of review a court should apply when analyzing these challenges. The

courts’ analyses of these questions are consequential, as the likelihood of a state action being upheld or
invalidated under the Equal Protection Clause may turn significantly on how a court resolves them. These
recent decisions not only dictate how lower courts within these circuits analyze such equal protection
challenges, but also may inform other courts’ approaches to similar equal protection challenges.
Equal Protection Background
The Fourteenth Amendment’s Equal Protection Clause prohibits states from denying individuals “the
equal protection of the laws.” In the most general terms, states must not classify or differentiate among
similarly situated individuals in a manner that violates this constitutional guarantee. When analyzing an
equal protection challenge, a court must first determine which legal standard to apply. The most
deferential standard of equal protection review is rational basis, under which a court will generally uphold
a challenged classification as long as it is reasonably related to a legitimate government purpose. Courts
subject classifications based on sex, however, to a more stringent standard—intermediate scrutiny. If
intermediate scrutiny applies, the parties seeking to defend a sex-based classification must show an
“exceedingly persuasive justification” or “important government interest” for classifying individuals
based on sex and must demonstrate that the classification is “substantially related” to achieving that
interest.
In equal protection challenges raised in another context—school restroom access—several federal
appellate courts have concluded that laws prohibiting transgender individuals from access consistent with
their gender identity amount to sex-based classifications subject to intermediate scrutiny. In addition, the
Fourth and Ninth Circuits have held that transgender individuals constitute a quasi-suspect class for equal
protection purposes—that is, a class of individuals who warrant heightened protection under the law—and
that transgender-based classifications are subject to intermediate scrutiny on that basis.
Challenges to State Laws in Federal Appellate Courts
When analyzing the legal bases for the preliminary injunctions at issue, the appellate courts considering
the challenges to the Arkansas, Tennessee, Kentucky, and Alabama laws differed on the applicable
standard of review. The Eighth Circuit construed the Arkansas law as classifying individuals based on
sex, held that intermediate scrutiny applied, and concluded it was likely that the plaintiffs would prevail
on their claim. By contrast, both the Sixth and Eleventh Circuits held that rational basis review applied
and that the challenged laws neither contained a sex classification nor targeted a quasi-suspect class. (The
Sixth and Eleventh Circuits also rejected arguments related to the Due Process Clause of the Fourteenth
Amendment, further discussion of which is beyond the scope of this Sidebar.)
Eighth Circuit: Brandt v. Rutledge
The Eighth Circuit affirmed a district court’s preliminary injunction of Arkansas’s law banning “gender
transition procedures” for minors, reasoning that the law was a sex classification that did not satisfy
intermediate scrutiny. Arkansas’s law bans procedures and drugs intended to remove or alter “physical or
anatomical characteristics or features that are typical for the individual’s biological sex” or “create
physiological or anatomical characteristics that resemble a sex different from the individual’s biological
sex.” Specific medical services identified in the law include puberty blockers, “cross-sex hormones,” and
“gender reassignment surgery.” Prohibited procedures do not include those for individuals “born with a
medically verifiable disorder of sex development.”
Reviewing the injunction, the Eighth Circuit reasoned that the law discriminates on the basis of sex
because medical procedures permitted for minors of one sex are denied to minors of another sex. For
instance, a minor born as a male can be prescribed testosterone, but a minor born as a female is not
permitted to receive that treatment. The court thus viewed the law as subject to intermediate scrutiny. The

state’s asserted justification for the law was its interest in protecting minors from “experimental medical
treatment” and regulating medical ethics. The Eighth Circuit concluded that there was substantial
evidence to support the district court’s findings that the medical treatments were a recognized standard of
care and “supported by medical evidence … subject to rigorous study.” The Eighth Circuit accordingly
determined that the lower court was not wrong to conclude the law’s prohibition was likely to fail
intermediate scrutiny, as it was not substantially related to the state’s interest in protecting minors from
experimental treatment and regulation of medical ethics.
The full Eighth Circuit later denied a petition for rehearing en banc, with five judges dissenting from the
denial and several others indicating that an appeal from a final judgment would offer the court a more
comprehensive record to review. Following a trial in the case, the district court entered a permanent
injunction against enforcement of the law, and that decision is now pending before the Eighth Circuit,
which has granted a petition for an initial hearing en banc.
Eleventh Circuit: Eknes-Tucker v. Governor of Alabama
In contrast to the Eighth Circuit’s analysis in Brandt, the Eleventh Circuit held that specific provisions of
a similar Alabama law did not amount to a sex-based or quasi-suspect classification for equal protection
purposes. The court concluded that the challenged provisions were “best understood as a law that targets
specific medical interventions for minors,” or as classifying based on age, and that it was “exceedingly
likely” that the provisions satisfied rational basis review.
The challenged provisions of Alabama’s law prohibit any person from prescribing or administering
“puberty blocking medication,” “supraphysiologic doses of testosterone or other androgens to females,”
and “supraphysiologic doses of estrogen to males,” when given “to attempt[] to alter the appearance of or
affirm the minor’s perception of his or her gender or sex, if that appearance or perception is inconsistent
with the minor’s sex as defined in this act.” The law’s other provisions, which were not challenged in the
Eknes-Tucker lawsuit, include a prohibition of specific surgical procedures. The Alabama law defines a
minor as a person under the age of 19, and defines sex to mean “‘[t]he biological state of being male or
female, based on the individual’s sex organs, chromosomes, and endogenous hormone profiles.’”
The Eleventh Circuit rejected the plaintiffs’ assertion that the provisions classify based on sex because the
law uses sex-based terms to criminalize certain treatments. The law refers to sex, the court decided, only
because the medical interventions at issue concern physiological sex characteristics. “[I]t is difficult to
imagine how a state might regulate the use of puberty blockers and cross-sex hormones . . . in specific
terms without referencing sex in some way,” the court observed. More significantly, the court reasoned
that the challenged provisions do not distinguish between men and women by denying an opportunity to
one sex but not the other—a key feature of sex-based classifications for equal protection purposes. Rather,
in the court’s view, the restrictions on puberty blockers and hormone treatment apply to all minors,
regardless of sex. The appellate court also rejected the argument, adopted by the lower court, that a
classification based on gender nonconformity “indirectly classifies on the basis of sex.” The appellate
court held that the lower court had relied on inapposite precedent to reach that conclusion, including a
Supreme Court decision interpreting Title VII of the Civil Rights Act of 1964. That decision, the court
reasoned, addressed a federal statute, not the different text and meaning of the Equal Protection Clause,
and did not concern the regulation of medical treatments. The Eleventh Circuit also rejected the view that
transgender persons constitute a quasi-suspect class distinct from sex.
The court did observe that the challenged provisions prohibit medical treatment for minors that only
gender nonconforming or transgender individuals would want to undergo. Addressing that distinction, the
court stated that the law would trigger heightened scrutiny if regulating medical treatment were “a pretext
for invidious discrimination against such individuals.” In the case before the court, however, “the district
court did not find that Alabama’s law was based on invidious discrimination.” Nor did the challenged

provisions “further any particular gender stereotype.” Rather, the provisions, in the court’s view, refer to
and “reflect[] biological differences between males and females.” In a concurring opinion, Judge Brasher
agreed that rational basis review was the applicable standard but added that even if intermediate scrutiny
applied to the challenged provisions of Alabama’s law, it was likely the state would satisfy that standard.
The plaintiffs have filed a petition seeking en banc review of the panel decision.
Sixth Circuit: L.W. ex rel. Williams v. Skrmetti
The Sixth Circuit reached a similar result in two separate cases where district courts granted preliminary
injunctions against Tennessee’s and Kentucky’s laws addressing hormones and puberty blockers. After
analyzing each injunction in separate initial rulings, the Sixth Circuit later issued a decision reversing
both injunctions. The Tennessee law bans certain medical treatments for minors that have the purpose of
enabling identification with “a purported identity inconsistent with the minor’s sex,” or addressing
“purported discomfort or distress from a discordance between the minor’s sex and asserted identity.”
Prohibited medical treatments include puberty blockers, hormones, and surgery. Similarly, Kentucky bars
medical providers from offering treatments “for the purpose of attempting to alter the appearance of, or to
validate a minor’s perception of, the minor’s sex, if that appearance or perception is inconsistent with the
minor’s sex.” Specifically prohibited treatments include puberty blockers, hormones, and surgery.
The Sixth Circuit ruled that the laws do not discriminate based on sex and thus were not subject to
heightened scrutiny. In an opinion by Chief Judge Sutton, the panel majority ruled that the challenged
provisions limit access to treatments for all children equally, “regardless of sex,” and treat “similarly
situated individuals evenhandedly.” The “key to the constitutionality” of the Tennessee and Kentucky
state laws, in the court’s view, was “that they do not disadvantage ‘persons’ based on their sex.” Rather,
whether these treatments are available to someone turns on “the age of the individual and the risk-reward
assessment of treating this medical condition.” Pointing to Supreme Court equal protection cases that had
found sex classifications, the Sixth Circuit distinguished the state laws at issue, concluding that they do
not prefer one sex to another, exclude one sex and include another, or distribute burdens or benefits based
on sex.
The plaintiffs argued that the laws do treat minors differently based on their sex—triggering heightened
scrutiny—because, for example, while a boy with abnormally low testosterone levels could be treated
with testosterone under the laws, a girl seeking to transition could not. The court rejected this argument,
pointing to Dobbs v. Jackson Women’s Health Organization, in which the Supreme Court determined that
laws which regulate “a medical procedure that only one sex can undergo” (such as pregnancy) do not
trigger heightened constitutional scrutiny. The Sixth Circuit reasoned that by “biological necessity,” these
hormone treatments are procedures “that only one sex can undergo.” Overall, the court concluded that
“the States treat boys and girls exactly the same for constitutional purposes—reasonably limiting
potentially irreversible procedures until they become adults.” The court also declined to apply heightened
scrutiny under the theory that transgender individuals constitute a quasi-suspect class. The court observed
that neither the Supreme Court nor the Sixth Circuit has recognized transgender status as a quasi-suspect
class, and the bar for recognizing a new quasi-suspect class is high.
Applying rational basis review, the court concluded that the laws satisfied that standard. The Sixth Circuit
observed that the “unsettled, developing, ... experimental[] nature of treatments in this area surely permits
more than one policy approach.” The court concluded that the states “offered considerable evidence about
the risks of these treatments and the flaws in existing research,” and the challengers’ disagreement with
the states’ assessment of the risks and proper response was not sufficient to invalidate the laws on rational
basis review. The court concluded by emphasizing that it did not doubt the existence of gender dysphoria
or the value of providing “psychological and related care to children facing it,” but judges should exercise
particular caution when asked to overrule or interfere with the policy decisions of legislatures in an
evolving medical area. The panel decision drew a dissent from Judge White. Judge White reasoned that

the laws discriminate on the basis of sex and trigger intermediate scrutiny. Applying intermediate scrutiny,
Judge White concluded that the laws “rested on improper generalizations about boys and girls” and that
their apparent purpose of protecting minors was not served by the classifications.
Seventh and Ninth Circuits
Although they have not issued opinions as of yet, the Seventh and Ninth Circuits have issued orders in
cases reviewing preliminary injunctions against Indiana’s and Idaho’s laws, respectively. The Seventh
Circuit issued a stay of the injunction against Indiana’s law after conducting oral arguments; by contrast,
the Ninth Circuit denied a stay of the preliminary injunction against Idaho’s law and did so before hearing
oral arguments. Idaho subsequently sought from the Supreme Court an emergency application for a stay
of the decision pending appeal. The application primarily focuses on the breadth of the preliminary
injunction, which prohibits the defendants from applying the law at all (including to non-parties).
However, the application also asserts that if the Supreme Court concludes that review of the constitutional
questions is “warranted now,” the Court should treat the application as a petition for certiorari before
judgment.
Considerations for Congress
The level of scrutiny that a court applies in an equal protection challenge can have crucial implications for
the outcome of a case. A court that construes a ban on certain medical treatments for transgender minors
as a sex-based classification, or that concludes transgender persons constitute a quasi-suspect status, is
more likely to invalidate a challenged law. In addition, as federal courts continue to address equal
protection challenges, it may be that this precedent develops differently depending on the specific context
at issue. Among other things, the asserted government interest at stake in an equal protection case, and the
strength of that interest, can vary from case to case. For instance, unlike the appellate court decisions
addressing the use of bathroom facilities by transgender students, where the asserted government interest
in denying access has been the protection of student privacy, the Eleventh Circuit in Eknes-Tucker found
that the challenged Alabama provisions were supported by the state’s compelling interest in “safeguarding
the physical and psychological well-being” of minors.
These considerations could have implications for federal statutes and regulations that may address
discrimination against transgender individuals. Congress possesses authority to amend these statutes and
to direct federal agencies in promulgating regulations that interpret them. For instance, Title IX of the
Education Amendments of 1972 prohibits discrimination “on the basis of sex” in federally funded
education programs, subject to various statutory exemptions. Section 1557 of the Affordable Care Act
prohibits discrimination on various bases in federally funded health programs. Two federal agencies
issued Notices of Proposed Rulemaking on Section 1557 and Title IX last year, proposing to construe
these statutes to prohibit certain actions based on transgender status, including the denial of certain
medical treatments. As equal protection precedent continues to develop, Congress could amend these
statutes’ prohibitions or exceptions or direct agencies to amend their implementing regulations.
