Overview

• The Supreme Court ruled on April 16, 2025, that 'woman' and 'sex' in the Equality Act 2010 refer exclusively to biological definitions, resolving years of legal ambiguity.
• Prime Minister Keir Starmer welcomed the ruling, stating it provides 'real clarity' and confirmed that trans women are not legally considered women under the Act.
• The Equality and Human Rights Commission is expediting guidance to help public bodies and businesses revise policies on single-sex spaces in line with the ruling.
• Tens of thousands protested in London over the weekend, criticizing the decision as harmful to the trans community, while government officials emphasized dignity and respect for all.
• The ruling allows single-sex services, such as hospital wards, refuges, and sports, to lawfully exclude trans women if deemed proportionate and necessary.
