The long battle for gender reality is drawing closer to an end. At least in the United Kingdom.

The UK Supreme Court has just ruled that a woman is someone born biologically female, ending the idea that men who identify as women have a right to women-only spaces. 

According to the Associated Press, the ruling allows transgender-identifying men to be excluded from spaces like women-only changing rooms and bathrooms.

It comes after the court upheld an appeal brought by For Women Scotland (FWS), a campaign group questioning whether men who identify as transgender are legally considered women under sex discrimination law.

The judgment focused on whether a man identifying as transgender and holding a “Gender Recognition Certificate” – a legal document recognising a person as their “preferred gender”—is protected from sex discrimination as a woman under the UK's Equality Act.

"The unanimous decision of this court is that the terms 'women' and 'sex' in the Equality Act 2010 refer to a biological woman and biological sex," Supreme Court deputy president Patrick Hodge said.

While the supreme court emphasised that the ruling did not diminish  protections against direct discrimination towards transgender-identifying people, it said certain protections should apply only to biological females and not men who identify as female, regardless of whether they hold a certificate.

The move could have repercussions globally including in Australia.

Just recently, an Australian court found that under the Sex Discrimination Act, sex is not binary and is changeable.

The UK decision could give legal weight to those arguing against the Australian decision.

HRLA clients including Billboard Chris and Jillian Spencer are also involved in court cases because of their firm stand on biological reality against transgender ideology.

Aidan O'Neill, a lawyer representing FWS, argued before the Supreme Court that the term "sex" in the Equality Act should be interpreted as biological sex, consistent with “ordinary, everyday language”.

“Our position is your sex, whether you are a man or a woman or a girl or a boy is determined from conception in utero, even before one's birth, by one's body,” he said.

“It is an expression of one's bodily reality. It is an immutable biological state.”

The conversation is changing globally. It’s just a matter of time before reality prevails in Australia too.
