Ten sporting bodies. One simple ask.

Women’s sport is protected by law – but not yet in practice.

Ten UK sports bodies have been formally warned they face legal action if they continue to allow males to compete in women’s categories – in breach of equality law as clarified by the UK Supreme Court.

The Legal Issue

One year on, women are still being sidelined.

Over a year after the landmark Supreme Court ruling that “woman” means biological female under the Equality Act, many UK sports governing bodies have still not updated their policies – leaving women and girls exposed to unfair competition and serious safeguarding risks.

The formal warnings were sent by Olympian Baroness Sharron Davies MBE, Tracy Edwards MBE – skipper of Maiden, the first all-female crew to circumnavigate the globe – and legal advocacy organisation ADF International.

The letters warn that any governing body continuing to permit males to compete in female categories has policies that are in breach of the law, exposing them to “immediate and substantial legal liability.”

The Equality Act 2010, along with the draft Equality and Human Rights Commission (EHRC) code, allows sports governing bodies to restrict the female category to biological females where physiological differences produce competitive disadvantage or safety risks.

“Biological sex is not a negotiable category; it is the essential foundation for safeguarding women and girls and preserving fair competition.”

Who’s Leading This Action

Sharron Davies

It is a true scandal that men are still allowed to compete against women in sport, a year after the Supreme Court ruling. All women who play sport must be able to do so in a safe and fair environment. Today, we put 10 sports bodies on notice.

When I stood outside the Supreme Court… as For Women Scotland won their case confirming the meaning of ‘woman’ in the Equality Act 2010 is defined as ‘biological sex’, I celebrated the return of sanity. Little did I know that a year later we would still be fighting for the female category in sport.

We are committed to protecting fair and safe competition in women’s sport across the United Kingdom. We will not hesitate to pursue all legal options, should these sport bodies not act to bring their policies in line with the law and biological reality.

The Legal Framework

The law is clear. And biological reality is undeniable.

Supreme Court: “woman” means biological female
In the landmark 2025 ruling in For Women Scotland v. The Scottish Ministers, the Supreme Court unanimously held that “woman” in the Equality Act 2010 refers to biological sex.
Court ruling: protecting the female category is lawful
Section 195 of the Equality Act permits sports governing bodies to protect the female category where physical differences would otherwise affect fairness or safety.
Court precedent: exclusion on biological sex grounds is lawful
In Haynes v English Blackball Pool Federation (2025), the court dismissed a discrimination claim brought by a biological male who had been excluded from female competitions. The ruling confirmed that excluding individuals from female categories on the basis of biological sex is lawful and proportionate, even in non-strength and non-contact sports such as pool.
Male puberty confers permanent, irreversible advantages
These include greater skeletal size, higher bone density, significantly increased muscle mass, superior cardiovascular output, and enhanced speed. Performance gaps typically range from 10–30%, and up to 50% in strength-dominant disciplines.
Safeguarding risks demand immediate action
The letters highlight the safeguarding risks of allowing males to use female changing rooms, along with increased insurance liability from elevated injury risk and potential discrimination claims by female athletes whose opportunities are displaced.
Draft EHRC guidance reinforces single-sex sport
Chapter 13 of the draft EHRC Code of Practice (2025 consultation) states that in sex-affected activities under Section 195 organisers may – and where physiological differences produce competitive disadvantage or safety risks, should – confine the female category to biological females.
