fakIt's completely unenforceable. This ruling has decided that sex = biological sex = sex assigned at birth = what is on your birth certificate. Except birth certificates can be changed, so what sort of proof will be accepted if you want to claim discrimination as a result of your sex? What sort of proof will be accepted to access spaces? There is none. They might try and prevent birth certificates from being changed (too late, btw) and then everyone has to carry one? Screw sex, stick to gender.
