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.

Maya Forstater

Maya Forstater came into the gender debate as the claimant in an employment-tribunal test case on belief discrimination, when she lost her job at the Center for Global Development after tweeting and writing about sex and gender. Her case established that ordinary beliefs about the two sexes are covered by the protected characteristic of belief in the Equality Act 2010.

Before co-founding Sex Matters she had 20 years’ experience as a researcher, writer and advisor working for think tanks and on multi-sector collaborations on business and sustainable development. Areas she has worked in include international tax policy, climate change and green finance, and human rights in supply chains, with businesses, NGOs and the UN. She co-founded the Let Toys Be Toys Campaign and was involved in setting up the Ethical Trading Initiative. She has a degree in agriculture.
