UK Supreme Court Backs ‘Biological’ Definition Of Woman

JUDGES at the United Kingdom (UK) Supreme Court have unanimously ruled that a woman is defined by biological sex under equalities law.
According to the British Broadcasting Corporation (BBC) report, the ruling marks the end of a long-running legal battle that could have major implications for how sex-based rights apply across Scotland, England and Wales are interpreted.
The court sided with campaign group, For Women Scotland, which brought a case against the Scottish Government, arguing that sex-based protections should only apply to people that are born female.
Judge Lord Hodge said the ruling should not be seen as a triumph of one side over the other, stressing that the law still gives protection against discrimination to transgender people.
The Scottish Government had argued that transgender people with a Gender Recognition Certificate (GRC) were entitled to the same sex-based protections as biological women.
The Supreme Court was asked to decide on the proper interpretation of the 2010 Equality Act, which applies across Britain.
Lord Hodge said the central question was how the words “woman” and “sex” are defined in the legislation, saying: “The unanimous decision of this court is that the terms, woman and sex, in the Equality Act 2010, refer to a biological woman and biological sex.
“But we counsel against reading this judgment as a triumph of one or more groups in our society at the expense of another, it is not.”
“The legislation gives transgender people protection, not only against discrimination through the protected characteristic of gender reassignment, but also against direct discrimination, indirect discrimination and harassment in substance in their acquired gender.”
Campaigners who brought the case against the Scottish Government hugged each other and punched the air as they left the courtroom, with several of them in tears.
The Equality Act provides protection against discrimination on the basis of various characteristics, including “sex” and “gender reassignment.”
The Judges were asked to rule on what that law means by “sex,” whether it means biological sex, or legal “certificated” sex, as defined by the 2004 Gender Recognition Act.
The Scottish Government argued that the 2004 legislation was clear that obtaining a GRC amounts to a change of sex “for all purposes.”
However, ‘For Women Scotland’ argued for a “common sense” interpretation of the words, man and woman, telling the court that sex is an “immutable biological state.”
Speaking outside the court following the ruling, the group’s Co-Founder, Susan Smith, said: “Today, the Judges have said what we always believed to be the case, that women are protected by their biological sex.
“Sex is real and women can now feel safe that services and spaces designated for women are for women, and we are enormously grateful to the Supreme Court for this ruling.”
First Minister, John Swinney, in a post on social media, said the Scottish Government accepted the judgment, adding: “The ruling gives clarity between two relevant pieces of legislation passed at Westminster.
“We will now engage on the implications of the ruling. Protecting the rights of all will underpin our actions.”
A Scottish Government spokesperson insisted that ministers had acted “in good faith” during the legal proceedings, noting that the Equality and Human Rights Commission was updating its guidance in response to the judgment.
A UK Government spokesman said the ruling would bring “clarity and confidence for women and service providers, such as hospitals, refuges and sports clubs.
“Single-sex spaces are protected in law and will always be protected by this government.”
Conservative Leader, Kemi Badenoch, described 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 the court strongly and clearly re-affirmed the Equality Act protects all trans people against discrimination, based on gender reassignment, and will continue to do so.”
However, deep concern remain over the landmark ruling. Harry Potter author, JK Rowling, in a social media post, said: “It took three extraordinary, tenacious Scottish women with an army behind them to get this case heard by the Supreme Court, and in winning, they’ve protected the rights of women and girls across the UK.”
Scottish Green MSP, Maggie Chapman, a prominent campaigner for trans-rights, said: “This is a deeply concerning ruling for human rights and a huge blow to some of the most marginalised people in our society.
“It could remove important protections and will leave many trans people and their loved ones deeply anxious and worried about how their lives will be affected and about what will come next.”
‘For Women Scotland’ had warned that if the court sided with the Scottish Government, it would have implications for the running of single-sex spaces and services, such as hospital wards, prisons, refuges and support groups.
Transgender people warned that the case could erode the protections they have against discrimination in their reassigned gender.
Scottish Trans manager, Vic Valentine, said the organisation was “shocked” by the court ruling, arguing that it “reverses 20 years of understanding on how the law recognises trans men and women with gender recognition certificates.”
They added: “This judgment seems to suggest that there will be times where trans people can be excluded from both men’s and women’s spaces and services.
“It is hard to understand where we would then be expected to go, or how this decision is compatible with a society that is fair and equal for everybody.”
The case follows years of heated debate over transgender and women’s rights, including controversy over transgender rapist, Isla Bryson, initially being put in a women’s prison, and an ongoing employment tribunal, involving a female NHS Fife nurse, who objected to a transgender doctor using a women’s changing room.
NHS Fife said it would “carefully consider” the court’s judgment.
The Judges ruled that interpreting sex as “certificated,” rather than “biological,” would “cut across the definitions of man and “woman and thus the protected characteristic of sex in an incoherent way.”
They said a “certified” definition of sex would weaken protections for lesbians, citing the example of lesbian-only spaces and associations, as it would mean that a trans woman who was attracted to women would be classed as a lesbian.
The ruling found the biological interpretation of sex was also required for single-sex spaces to “function coherently,” citing changing rooms, hostels, medical services and single-sex higher education institutions.
The Judges noted that “similar confusion and impracticability” had arisen in relation to single-sex associations and charities, women’s sport, public sector equality and the armed forces, noting: “The practical problems that arise under a certificated sex approach are clear indicators that this interpretation is not correct.”
Gender reassignment is a protected characteristic in law, making it is illegal to discriminate against someone on the basis that they are transgender.
However, single-sex spaces can exclude people with GRCs “if it is proportionate to do so.”
The legal dispute began in 2018 when the Scottish Parliament passed a Bill designed to ensure gender balance on public sector boards.
‘For Women Scotland’ complained that ministers had included transgender people as part of the quotas in that law.
The issue has been contested several times in the Scottish courts. Holyrood ministers won the most recent case in Scotland, with Judge, Lady Haldane, ruling in 2022 that the definition of sex was “not limited to biological or birth sex.”
The Scottish Parliament passed reforms that year that would have made it easier for someone to change their legally recognised sex, but the move was blocked by the UK Government and has since been dropped by Holyrood ministers.
The UK’s highest court ruled that the legal definition of “woman” excludes trans women, in a case with sweeping consequences for how equality laws are applied.
Britain’s Supreme Court ruled unanimously that the definition of a woman in equality legislation refers to “a biological woman and biological sex,” sparking celebrations outside court among gender-critical campaigners, but warnings that it was a “worrying” development for transgender people.
