Urgh. That does sound like a mess.
On a positive note, it completely stops children being brought in to the same bracket as adults. They are service users, not employees. So that's another reason why the conflation of the GRC with gender reassignment can't be used to deny single sex changing facilities etc for children.
The middle bit got complicated, but if I understand it correctly, the schedule 22 bit towards the end provides the anchor that's needed to highlight the intent (biological sex, not legal sex) behind the law because a) it's about physical body differences, which include strength/vulnerability differences b) it would render it illegal to provide single sex facilities at all.
If FWS lose at the Supreme Court, it sounds like it would be against the law for employers to provide single sex facilities for their staff (point b above) .... and surely that could be shown to be farcical, because it must hopefully be obvious that this was never the intent 🤞
This seems to be the key bit:
In my view, requiring separate toilet and changing facilities for men and women can fairly be said to protect women from risks specifically affecting women; namely, the threat of male violence and infringement of privacy while in a state of vulnerability and undress.
This isn’t a natural home for these exceptions. But the exceptions for separate and single-sex services only apply to services provided to the public or a section of the public. Provisions relating to the workplace have no equivalent. The closest we have is Schedule 22.
Ff I am right that this is the only textual foundation for the lawful provision of female-only facilities in the workplace, that has significant implications for For Women Scotland v The Scottish Ministers. That is because it means that all provision for separate or single sex facilities in the workplace is tied to the meaning of the word “woman” in the Equality Act. That is exactly the word that is contested in this case. It has a statutory definition in s.212 as “a female of any age”, and the case is about whether female means biological female or “legal” female, as determined by possession of the GRC.
