WASHINGTON — The Supreme Court on Wednesday upheld a Tennessee law restricting gender transition care for minors, delivering a major blow to transgender rights.
The 6-3 ruling is likely to have a broad impact as 24 other states have already enacted laws similar to the one in Tennessee, which bars gender transition surgery, puberty blockers and hormone therapy for youth.
Those laws now look set to survive similar legal challenges. The ruling does not affect states that do not have such bans, meaning care in those states will still be available.
The court was divided on ideological lines, with the six conservatives in the majority and the three liberals in dissent.
Writing for the majority, Chief Justice John Roberts concluded that the Tennessee law does not constitute a form of sex discrimination that would violate the Constitution's 14th Amendment.
"This case carries with it the weight of fierce scientific and policy debates about the safety, efficacy, and propriety of medical treatments in an evolving field," Roberts wrote. "The voices in these debates raise sincere concerns; the implications for all are profound."
"The Equal Protection Clause does not resolve these disagreements," he added.
Liberal Justice Sonia Sotomayor wrote in a dissenting opinion that contrary to the majority's conclusion, the law does discriminate based on both sex and transgender status and should therefore be analyzed closely.
"By retreating from meaningful judicial review exactly where it matters most, the court abandons transgender children and their families to political whims," she wrote. "In sadness, I dissent."
Sotomayor also took the relatively unusual step of reading a summary of her decision from the bench in court, saying the impact of the decision is "incredibly dangerous."
Trans rights activists have warned that a ruling allowing bans on care for trans minors could pave the way for similar restrictions aimed at adults.
"Today's ruling is a devastating loss for transgender people, our families, and everyone who cares about the Constitution," Chase Strangio, a lawyer with the American Civil Liberties Union who represents the challengers, said in a statement.
Tennessee Attorney General Jonathan Skrmetti welcomed the decision as a win for "common sense over judicial activism."

He added that legislators should give "careful scrutiny" before allowing such treatments, making judgments "based on science, not ideology."
The legal challenge was brought by the administration of former President Joe Biden, as well as transgender teens and their families.

The ruling does not resolve all legal issues relating to the state bans, as it did not address a separate argument under the 14th Amendment that the laws violate the right of parents to make health care decisions for their children.
The court also did not rule on the question of whether laws that discriminate against transgender people are subject to what is called "heightened scrutiny," meaning that judges should review them with a skeptical eye. But three of the conservative justices said transgender people are not a "suspect class," meaning laws targeting them should not receive heightened scrutiny.
Other issues involving transgender rights, such as laws blocking transgender girls from participating in sports, are likely to reach the court in due course.
Upon taking office in January, President Donald Trump has set about unwinding Biden policies that sought to bolster transgender rights. Among other things, he signed an executive order seeking to restrict gender-affirming care for teenagers nationwide. A judge quickly blocked it.
Trump has also imposed new restrictions on transgender people serving in the military.
"President Trump will continue to speak out and take action to protect innocent American children from these barbaric procedures that are based on junk science," White House spokeswoman Liz Huston said in a statement praising the ruling.
Enacted in 2023, the Tennessee law is among a wave of similar measures taken by states imposing restrictions on gender transition treatments. In defending its ban, the state's lawyers pointed to similar measures taken in other countries, including in Europe.
Skrmetti emphasized in court papers the evolving debate over how best to treat minors diagnosed with gender dysphoria, the clinical term given to the distress people can experience when their gender identities are in conflict with the genders assigned to them at birth.
Major medical organizations say gender-affirming treatments are an effective way to treat gender dysphoria.
"Let us be clear — healthcare bans of any kind are rooted in stigma, misinformation, and fear and this one comes at the expense of the youth in need of this care," the World Professional Association for Transgender Health and its United States affiliate, said in a statement.
The challengers argued that the law is a form of sex discrimination that violates the 14th Amendment's equal protection clause because the treatments at issue in the case — puberty blockers and hormone therapy — can be used in other situations.
The case marks the most significant ruling on transgender rights since the court in 2020, to the surprise of many, ruled that federal employment protections extend to gender identity, as well as sexual orientation.
The dispute reached the Supreme Court after the Cincinnati-based 6th U.S. Circuit Court of Appeals in 2023 rejected challenges to the Tennessee law and a similar measure in Kentucky.
A district court judge had blocked parts of the law, while concluding that the plaintiffs did not have legal standing to challenge the surgery ban. That provision of the law was not at issue before the Supreme Court.
