FFS I don't know whether all this 'how many angels can dance on the head of a pin' or 'if someone pees in the forest and no-one notices is this against the law' stuff, with ever more complicated scenarios is more ridiculous or annoying. Or maybe both.
The EHRC are trying to make it crystal clear that as far as toilets are concerned men should go in the men's and women in the women's. The terms men and women are sex based. There are some details about this which are clearly explained. If someone wants to use a toilet and is not sure which one to use they should enquire of the provider or the EHRC. This guidance should enable the correct choice to be made in nearly all cases.
If you are a woman use the women's toilet. If you are a woman who passes so well as a man you are going to fool all the men and frighten other women, probably best if you use the men's. Everything else is a men's problem, let them sort it. I like the clarity of that.
The 88 page judgement, summary and now this, plus advice from Sex Matters are models of clarity. Why are people getting their knickers in such a twist? Rhetorical question I know the answer.

But perhaps I'm overthinking this.
Yes, I think you are. I have no answers for you as I can't understand the question. The people involved should get proper legal advice. IE Not Stonewall legal advice.
