The UK’s Supreme Court has ruled that “man”, “woman” and “sex” in the Equality Act 2010 refer to sex, not self-ID or paperwork (gender-recognition certificates). This agreed with our legal interpretation. We have published new guidance and are in the process of updating our publications to reflect the judgment. We are also working to provide answers to the questions we're hearing from supporters and the media. We will publish these as soon as possible.
Employers that do not communicate and enforce clear policies about separate-sex facilities are likely to be in breach of both workplace health and safety regulations, and the Equality Act. Sex Matters signposts the relevant legislation and explains the effect of the April 2025 Supreme Court judgment.
