This is actually really positive. Men claiming to be women will never be able to enter female only provision again. At best, they can hope for mixed sex, and that also paves the way for third spaces/mixed sex in addition to single sex provision. Because any refusal to accept this is the new normal gives only the option to stick to the male single sex option if third spaces aren’t what they want.
This is a link to an archive version of the times article by Reindorf on what the judgement means:
https://archive.ph/1j6v5
and this section helps clarify this further:
“Single-sex arrangements are not mandatory in competitive sports or services open to the public, such as gym changing rooms or refuges for victims of domestic violence. However, it is likely to be discrimination against women not to provide them where they are appropriate, and public authorities must pay particular attention to making adequate provision for women under the public sector equality duty.”
So my reading of all of this is:
Defiant orgs who want to continue to provide ‘male inclusive’ provisions for women can choose to do so, under the correct banner of mixed sex. However, if a refusal to also provide female only (if necessary - and toilets/changing rooms I’d argue are necessary to be single sex for privacy & dignity & safety) leaves women at a disadvantage, they’re in breach of the law & are open to discrimination claims from women.
I am not a lawyer so happy to be corrected.
