The United States Supreme Court has handed down a landmark decision striking at the heart of so-called “conversion therapy” bans. These are laws that, in reality, have increasingly functioned as sweeping restrictions on speech, conscience, and the freedom to live in accordance with one’s faith.

At the centre of this case is Kaley Chiles, a Christian counsellor in Colorado. Her story is not one of coercion or harm, but of compassion: a professional seeking to walk alongside clients who voluntarily sought counselling consistent with their faith. Yet under Colorado’s “Minor Conversion Therapy Law”, Chiles was prohibited from engaging in precisely that kind of conversation.

The law sought to outlaw efforts to “change an individual’s sexual orientation or gender expression.” But in practice, its reach extended far beyond any reasonable understanding of harmful conduct. It captured ordinary talk therapy, voluntary counselling, and even conversations initiated by clients themselves, those wrestling with deeply personal questions about identity, belief, and the shape of their lives.

In striking the law down, the Supreme Court reaffirmed a foundational principle: that governments have no authority to police the content of private, consensual conversations simply because they disapprove of the viewpoints expressed.

The Court described Colorado’s law as an “egregious” violation of the nation’s commitment to free thought and free speech, recognizing that when the state dictates which perspectives may be expressed in the counselling room, it crosses a line from regulation into ideological enforcement.

This is a significant victory for religious liberty because it preserves the freedom of individuals to seek counsel aligned with their own convictions. At the heart of this case were Christian counsellors trying to help young people live in accordance with their faith. Effectively, the state told young people that this kind of counselling is illegitimate and prevented them from seeking the help they wanted.

Across Australia, similar legislative frameworks have taken root. Victoria’s laws are among the most expansive in the world, with provisions that have been widely criticised for their breadth. New South Wales and other jurisdictions have followed suit, embedding restrictions that risk silencing legitimate expressions of belief and care.

For organisations like the Human Rights Law Alliance, this decision of the US Supreme Court underscores the urgency of continued advocacy in Australia. The question is not whether governments should protect vulnerable individuals. The question is whether governments should limit fundamental freedoms of speech, conscience, and religion to prevent unfashionable viewpoints from being heard.

America’s First Amendment provides strong protection for free speech. Australia lacks such a robust protection in its Constitution.

That’s why Australia needs to stay vigilant in its defence of fundamental freedoms.
