Dublin, Ireland — April 16 — The UK Supreme Court has delivered a landmark ruling affirming that under the Equality Act 2010, the term “woman” refers specifically to biological sex. The unanimous judgment is expected to have far-reaching implications for how sex-based rights are interpreted across England, Scotland, and Wales.
The case, brought by the campaign group For Women Scotland, challenged the Scottish government’s stance that individuals who have legally changed gender through a Gender Recognition Certificate (GRC) should be considered as having changed their sex for all legal purposes, including access to single-sex spaces and services.
In delivering the judgment, Deputy President of the Supreme Court, Lord Hodge, said: “The unanimous decision of this court is that the terms ‘woman’ and ‘sex’ in the Equality Act 2010 refer to biological woman and biological sex.”
He cautioned against interpreting the ruling as a victory for one side at the expense of another. “We counsel against reading this judgment as a triumph of one or more groups in our society over others. It is not. The law continues to protect transgender people against discrimination through the protected characteristic of gender reassignment,” he added.
At the heart of the case was the interpretation of two major UK laws: the Equality Act 2010 and the Gender Recognition Act 2004. The Equality Act offers protections based on various characteristics, including sex and gender reassignment.
The Scottish government argued that a GRC effectively changes an individual’s legal sex, giving them equal standing in law for sex-based rights. For Women Scotland argued that sex should be defined by immutable biological traits, not legal documents.
Campaigners who brought the case were visibly emotional as they left the courtroom. Susan Smith, co-founder of For Women Scotland, described the ruling as a victory for common sense.
“Today the judges have said what we always believed to be the case — that women are protected on the basis of their biological sex,” she said. “Sex is real, and women can now feel safe that spaces and services intended for them remain exclusive to them. We are enormously grateful to the Supreme Court for this ruling.”
The Scottish government, while expressing disappointment, said it would accept the ruling and assess its implications. First Minister John Swinney posted on social media: “The ruling gives clarity between two relevant pieces of legislation passed at Westminster. We will now engage on the implications. Protecting the rights of all will underpin our actions.”
The UK government welcomed the decision. A spokesperson said the judgment “brings clarity and confidence for women and service providers such as hospitals, refuges, and sports clubs,” affirming that “single-sex spaces are protected in law and will always be protected by this government.”
Equalities Minister Kemi Badenoch hailed the ruling as “a victory for all of the women who faced personal abuse or lost their jobs for stating the obvious.”
She added: “It’s important to be reminded that the court clearly reaffirmed that the Equality Act continues to protect all transgender people against discrimination based on gender reassignment.”
The ruling is expected to influence policy debates and legislation concerning gender, rights, and access to services across the UK for years to come.
