The Scottish government has been left "humiliated" after the Supreme Court ruled in favour of biological women - a landmark ruling against trans women.
Following a challenge by campaign group For Women Scotland, Lord Hodge declared that the Equality Act 2010 refers to "a biological woman and sex".
Lord Hodge told the court: "Our role is to ascertain the meaning of the legislation which parliament has enacted to that end. The central question on this appeal is the meaning of the terms woman and sex in the Equality Act 2010.
"Do those terms refer to biological women or biological sex? Or is a woman to be interpreted as extending to a trans woman with a gender recognition certificate?"

Reacting to the ruling, Alba Party MSP Ash Regan declared the decision a "victory for women and for common sense".
Expressing her delight, Regan told GB News: "We are absolutely delighted for For Women Scotland to have won their court case today at the Supreme Court, to find a final definition on what is a woman.
"The biological definition of women is what has been upheld by the court, which is obviously a victory for women right across Scotland, but it is also a victory for common sense."
Hitting out at the Scottish government, Regan claimed that they have been left "exposed" and "humiliated" by the court's decision.

Regan stated: "It should never have come to this. It should never have taken three ordinary Scottish mums to fight the Scottish government all the way to the Supreme Court to get an answer on this.
"And unfortunately, the Scottish government has been very much exposed now. They have been humiliated in court and they must now roll back this ideology right across Scotland."
Highlighting how the ruling affects transgender issues facing women across the country, Regan emphasised how women's spaces, particularly in sport, have becoming a prominent concern in campaigning for women's rights and women's safety.
Regan explained: "This has been affecting women, not just in Scotland, but obviously across the world. And in the UK, it was affecting women in terms of participation in sport, and women being asked to get changed, to be in a position of vulnerability, when men are allowed in the changing rooms.

"We have had problems maintaining single sex spaces, we have violent male offenders in the women's prison estate - this has to stop now."
Calling on the Scottish government to take action, Regan urged them to "take the ruling seriously" and "recognise they have been roundly beaten".
Regan concluded: "I haven't got a lot of sympathy for them. They were warned repeatedly by myself and by many other women, that this did interfere with the Equality Act, that it created a hierarchy of rights, and it was the wrong thing to do.
"They did not listen. So they only have themselves to blame for this now, but I hope they take this seriously, they recognise they have been roundly beaten, that their magical thinking that is dangerous for women is now finished, and they need to roll back this ideology."
First Minister John Swinney said the Scottish Government "accepts today’s Supreme Court judgment" in the For Women Scotland appeal against Scottish ministers on the legal definition of a woman.
