In a landmark ruling, the UK Supreme Court held that the legal meaning of a woman is determined on the basis of biological sex. The court once again clarified that this ruling isn’t a victory for one group over the other since it nonetheless maintains protections from discrimination for trans people.
This ruling is following a lengthy court struggle between the Scottish government and a women’s rights campaigning group. The Scottish government had argued that individuals who have a Gender Recognition Certificate (GRC) should be entitled to sex-based protections, whereas For Women Scotland argued the protections should only be entitled to those born female.
In its comprehensive 88-page ruling, the court noted, “The definition of sex in the Equality Act 2010 clearly articulates that the concept of sex is binary; an individual is a woman or a man. Individuals having that attribute safeguarded for purposes of group-based protection and rights are individuals of the same sex, and provisions invoking protection for women exclude men categorically.”
The court further added, “While the word ‘biological’ is not employed in this definition, the plain sense of those simple words is in accord with the biological differences which make a man or woman. These characteristics speak for themselves and require no explanation. Men and women are separated in this definition on the basis of biology alone.”
Importantly, the court made it clear that transgender individuals still enjoy the legal cover. It stated, “The Equality Act 2010 provides transgender people with protection not only against discrimination through the protected characteristic of gender reassignment but also against direct discrimination, indirect discrimination, and harassment on their acquired gender.”
This ruling is especially significant in the ongoing controversy over gender identity and legal status in the UK. It attempts to reconcile earlier understandings with the rights of transgender individuals.
