Britain’s Supreme Court has ruled that the legal definition of a “woman” under the Equality Act 2010 refers strictly to biological sex, delivering a landmark judgment that could reshape the legal landscape surrounding transgender rights in the UK.
The unanimous decision by five judges in London marked a significant victory for Scottish campaign group For Women Scotland (FWS), which has long contended that biological sex must remain the basis for defining womanhood in law.
In its ruling on Wednesday, the court clarified that while transgender individuals are protected under the Equality Act through the provision of gender reassignment, this protection does not alter the core legal definitions of “sex” or “woman.”
“The terms ‘woman’ and ‘sex’ in the Equality Act 2010 refer to a biological woman, and biological sex,” Justice Patrick Hodge said in delivering the verdict. However, he emphasized that transgender people retain protection against discrimination under other provisions of the Act.
The case stemmed from a dispute over a Scottish law designed to increase female representation in public bodies. FWS challenged the Scottish government’s interpretation that transgender women with a Gender Recognition Certificate (GRC) should be treated as biological women under the Equality Act.
The court ruled the Scottish government’s interpretation was legally flawed and inconsistent with both the Equality Act and the 2004 Gender Recognition Act. The justices stated that interpreting “woman” to include individuals with a GRC would disrupt the coherence of legal protections rooted in biological sex.
The decision was met with celebration from gender-critical activists outside the court in London.

“Today, the judges have said what we always believed to be the case: that women are protected by their biological sex,” said Susan Smith, co-director of FWS.
The ruling, while affirming legal safeguards for transgender individuals, is seen as a setback for trans rights campaigners, who fear it may restrict access to single-sex spaces such as changing rooms, hostels, and healthcare facilities.
Justice Hodge acknowledged the emotional weight of the issue, noting “the strength of feeling on all sides,” and recognized the vulnerabilities of both women facing sex discrimination and transgender individuals seeking recognition.
The judgment comes amid intensifying global scrutiny of transgender rights. In the United States, President Donald Trump has adopted a hardline stance, rolling back protections and asserting a federal definition of sex as exclusively male or female.
In the UK, the ruling may now pressure Prime Minister Keir Starmer’s Labour government to clarify its position on gender recognition and single-sex spaces. The previous Conservative government had already blocked Scottish efforts to simplify legal gender change, siding with biological definitions.
The case, and now the ruling, underscore the deep divisions in British society on the balance between gender identity and biological sex — a debate that continues to stir passionate discourse from activists, legal scholars, and the public alike.
