UK Supreme Court Upholds Biological Definition of “Woman”

In a landmark decision on Wednesday, the Supreme Court of the United Kingdom upheld the biological definition of “woman,” ruling that transgender women do not meet this classification under the country’s Equality Act of 2010. Justice Patrick Hodge, speaking on behalf of the unanimous decision by all five judges, emphasized that the terms “woman” and “sex” within the legislation specifically refer to biological sex and biological women.

Justice Hodge further explained, “The Equality Act 2010 provides protections for transgender individuals, not only against discrimination but also through the characteristic of gender reassignment.” He clarified that a transgender person, even with documentation recognizing them as female, does not qualify as a woman for the purposes of equality under this Act.

Background of the Legal Challenge

The issue came to the forefront in 2018 following a legislative change by the Scottish Parliament, which mandated that women must comprise 50% of the representatives on public boards in Scotland. Subsequently, Scottish authorities expanded this definition to include transgender women who possess a Gender Recognition Certificate, thereby legally recognizing their female status under the Equality Act, to fulfill these quotas.

The redefinition by Scottish officials was contested by For Women Scotland (FWS), a women’s rights advocacy group. They argued that this interpretation exceeded the powers of Parliament and could lead to scenarios where public boards might consist of 50% biological men and 50% men with gender recognition certificates, yet still claim to meet the female representation requirements. Trina Budge, director of FWS, highlighted the potential distortion of the original intent of the law, stating, “Not tying the definition of sex to its ordinary meaning allows for a misrepresentation of actual female participation on these boards.”

Implications of the Ruling

This definitive ruling by the UK Supreme Court is poised to significantly influence sex-based rights and the governance of single-sex facilities throughout the country. It reinforces the principle that biological realities cannot be overridden by subjective identifications, ensuring that men, regardless of their gender identity, are not permitted access to spaces designated for women. This decision is a victory for those advocating for the preservation of women’s spaces and rights in alignment with biological distinctions.
