The Supreme Court delivered a landmark 6-3 ruling Monday striking down Colorado's ban on conversion therapy for minors, determining that the state law "regulates speech based on viewpoint" and violates the First Amendment's free speech protections. The decision, which marks the first time the nation's highest court has directly addressed conversion therapy legislation, could impact similar laws in 20 other states and the District of Columbia that have enacted comparable restrictions on the controversial practice.
The Context
Colorado enacted its conversion therapy ban in 2019 as part of a nationwide movement to restrict practices aimed at changing a person's sexual orientation or gender identity. The law prohibited licensed mental health professionals from engaging in conversion therapy with patients under 18, defining such practices as "any counseling, practice, or treatment performed with the goal of changing an individual's sexual orientation or gender identity." Since California became the first state to ban the practice in 2012, 21 states and dozens of municipalities have passed similar legislation, affecting an estimated 698,000 LGBTQ+ youth nationwide, according to the Williams Institute at UCLA School of Law.
The legal challenge originated in 2020 when Dr. Kaeley Triller, a licensed counselor in Denver, filed suit against the state alongside the Alliance Defending Freedom, arguing that the ban prevented her from providing "biblically-based counseling" to clients seeking to align their behavior with their religious beliefs. The case, Triller v. Colorado Department of Regulatory Agencies, worked its way through federal courts, with the 10th Circuit Court of Appeals upholding Colorado's law in 2024 before the Supreme Court agreed to hear the case in October 2025.
What's Happening
Writing for the majority, Chief Justice John Roberts argued that Colorado's law constituted impermissible viewpoint discrimination under the First Amendment. "The State has prohibited counselors from expressing particular viewpoints about sexual orientation and gender identity to minors, while permitting counselors to express opposing viewpoints," Roberts wrote in the 47-page opinion. "This differential treatment based on the speaker's viewpoint runs afoul of the First Amendment's central prohibition on content-based restrictions of speech." The ruling was joined by Justices Clarence Thomas, Samuel Alito, Neil Gorsuch, Brett Kavanaugh, and Amy Coney Barrett.
Justice Elena Kagan authored the dissent, joined by Justices Sonia Sotomayor and Ketanji Brown Jackson, arguing that the majority had mischaracterized professional conduct regulations as speech restrictions. "Colorado's law regulates professional conduct, not speech," Kagan wrote. "When the State licenses professionals to provide medical or therapeutic services, it may impose reasonable regulations on how those services are provided, including restrictions on harmful practices." The dissent cited extensive medical evidence documenting the psychological harm associated with conversion therapy, including a 2020 study by the American Journal of Public Health showing doubled suicide attempt rates among LGBTQ+ youth subjected to such practices.
The Analysis
Legal experts immediately characterized the decision as a significant expansion of First Amendment protections for professional speech, potentially affecting regulations across various licensed professions. "This ruling fundamentally alters the landscape for professional licensing and regulation," said Professor Eugene Volokh of UCLA Law School, who filed an amicus brief supporting the challenge. "If states cannot regulate professional speech based on the content or viewpoint expressed, we may see challenges to medical licensing requirements, therapy guidelines, and even legal professional conduct rules." The decision represents the Court's most expansive interpretation of professional speech rights since the 2018 ruling in National Institute of Family and Life Advocates v. Becerra, which struck down California's requirement that crisis pregnancy centers provide information about abortion services.
Medical and mental health organizations expressed strong opposition to the ruling, with the American Psychological Association releasing a statement within hours of the decision. "This ruling ignores decades of scientific evidence demonstrating that conversion therapy is ineffective and harmful," said APA President Dr. Jennifer Kelly. "Our concern is that this decision will lead to increased discrimination and psychological harm against LGBTQ+ youth." The American Academy of Pediatrics, American Medical Association, and World Health Organization have all condemned conversion therapy practices, with the WHO removing homosexuality from its list of mental disorders in 1992.
Political reactions split along predictable lines, with Republican governors in states without conversion therapy bans praising the decision while Democratic leaders vowed to explore alternative regulatory approaches. Colorado Governor Jared Polis, a Democrat who is openly gay, announced that his administration would work with state legislators to craft new legislation focused on consumer protection rather than speech restrictions. "We will explore every available avenue to protect Colorado's LGBTQ+ youth from harmful and discredited practices," Polis said in a statement.
What Comes Next
The immediate impact of the ruling remains unclear, as existing conversion therapy bans in other states may face renewed legal challenges while new cases work through federal courts. The Trevor Project, an LGBTQ+ youth suicide prevention organization, reported a 73% increase in calls to its crisis hotline in the 24 hours following the decision, prompting the group to activate additional counseling resources. Legal challenges to similar laws in California, New York, and Illinois are expected to be filed within the coming weeks, according to the Alliance Defending Freedom, which represented the successful plaintiffs.
State lawmakers are already exploring alternative regulatory frameworks that might survive First Amendment scrutiny under the new standard. These could include consumer protection laws focusing on fraudulent claims about treatment efficacy, professional licensing requirements tied to evidence-based practices, or age-specific regulations that emphasize parental rights rather than speech content. The Court's opinion suggests that narrowly tailored regulations addressing demonstrable harm rather than viewpoint might withstand constitutional challenge, but the exact boundaries remain to be tested through future litigation.
The decision arrives as LGBTQ+ rights face renewed scrutiny at both state and federal levels, with over 400 bills targeting LGBTQ+ individuals introduced in state legislatures during the 2025 session alone. Mental health advocates warn that the combination of reduced conversion therapy restrictions and increased political hostility could create a "perfect storm" of harm for vulnerable youth, while religious freedom advocates celebrate what they view as a victory for constitutional protections of conscience and belief.
