Is the Supreme Court ruling on sex and gender actually law? Do trans people have to follow it?
The Supreme Court ruling interpreted the meaning of 'sex' in the Equality Act 2010 for specific purposes; it did not remove the separate legal protection that trans people have under the gender reassignment characteristic within that same Act. EHRC guidance issued in response is not binding law and remains subject to legal challenge. Trans people retain rights under both the Equality Act 2010 and the Human Rights Act 1998.
What the Supreme Court actually decided
In April 2025, the UK Supreme Court ruled that the words "woman" and "sex" in the Equality Act 2010 refer to biological sex for the purposes of that Act. This was a ruling about how a specific piece of legislation should be interpreted in a specific context. It was not a ruling that trans people are less than human, that their identities are invalid, or that they lose all legal protection. It was a statutory interpretation judgment, and a contested one at that.
Crucially, the protected characteristic of gender reassignment remains entirely intact within the Equality Act. A trans person who is treated unfairly, harassed, or disadvantaged because they are trans still has full legal recourse under that Act. That has not changed. The judgment narrowed the interpretation of "sex" in certain contexts; it did not erase trans people from the law's protection.
What the EHRC guidance is and is not
Following the ruling, the Equality and Human Rights Commission published interim guidance. That guidance is not binding law. It is the EHRC's interpretation of how organisations might apply the judgment, and it has already attracted significant criticism from legal experts, equalities professionals, and trans rights organisations. Guidance can be challenged, revised, and overturned. It is not a statute. It does not carry the same legal weight as the Equality Act itself, and it should not be treated as though it does.
Courts interpret the law, they do not always get it right
Legal history is full of judgments that were later understood to be wrong, unjust, or incompatible with the values of a decent society. Courts work within the framework of arguments put before them, the legislation as currently drafted, and the social understanding of the time. The Human Rights Act 1998 incorporates the European Convention on Human Rights into UK law, including Article 8 (the right to private and family life) and Article 14 (freedom from discrimination). These rights do not disappear because of a Supreme Court ruling on statutory interpretation.
Trans people have human rights. Those rights are grounded in international law and in the domestic legislation of this country. A single judgment about the meaning of one word in one Act does not undo that foundation.
What this means for trans people in practice
You do not have to accept a diminished version of yourself because of how a court has interpreted a word. You are still protected from discrimination on the grounds of gender reassignment. You are still entitled to dignity, privacy, and equal treatment. If you are refused services, treated with contempt, or excluded on the basis of being trans, you still have legal routes available to you.
The situation is genuinely uncertain in some areas, and I will not pretend otherwise. But uncertainty is not the same as defeat. Many legal challenges are ongoing, and the full implications of this ruling will be worked through in courts, in Parliament, and in public life over the coming months and years. Trans people, their families, and their allies have every reason to remain engaged and to keep pushing for the fair treatment that was always owed to them.
Where I stand
I believe in the dignity and validity of every trans person. I believe that inclusion is not a political opinion but a moral baseline. The science of gender diversity is clear, the clinical evidence for gender-affirming care is well established in frameworks including the WPATH Standards of Care 8 and the Endocrine Society guidelines, and the humanity of trans people is not up for legal debate, whatever any court may say about the meaning of a single word in a single statute.
If you are living honestly, treating others with kindness, and asking only to be treated with the same respect in return, you are on solid ground. The law is a living thing and it continues to evolve. People who care about justice are already working to make sure it evolves in the right direction.
