UK Supreme Court: The Definition of Sex in the Equality Act
The Inner House of the Court of Session Judgment
We believe the Equality Act was drafted on the basis of the ordinary, common law understanding of the biological differences between the two sexes. The protected characteristic of “sex” in the Equality Act is defined as a reference to a man or a woman, where man means “a male of any age” and woman means “a female of any age”. We think it is quite clear that these are distinct and separate groups and that “woman” is not a mixed-sex category.
However, in our recent judicial review, For Women Scotland v The Scottish Ministers [2023] CSIH 37, the Inner House took the opposite view and decided there is a relationship between the Gender Recognition Act 2004 (GRA) and Equality Act 2010 and held that the meaning of sex in the Equality Act incorporated the GRA framework.
The court decision stated that a person with a Gender Recognition Certificate (GRC) in their acquired gender has the protected characteristic of gender reassignment. Separately, they also possess the protected characteristic of sex according to the terms of their GRC and have a presumptive right to access the single-sex services of their acquired gender.
The Supreme Court will consider a request brought by For Women Scotland (FWS) who argue there are “strong grounds” for its challenge, which will almost certainly overturn contentious Scottish government legislation if successful.Campaigners for women’s “sex-based” rights reacted with delight to the news, including Magi Gibson, the poet, who posted on X/Twitter, that it was “game on” on in the “fight for the protection of women’s rights within the UK legal system”.Dennis Noel Kavanagh, a lawyer and the director of Gay Men’s Network, said: “Getting permission to go to the Supreme Court is really hard and very rare but FWS have it. The question ‘what is a woman’ in law will now be heard by our highest court. Massive news.”
