Wow, that was quick.
So... I do actually have some questions about this from the point of view of trans people.
It says very clearly that trans people should not use single sex toilets for members of the opposite sex, but that in some circumstances it may also be reasonable to exclude them from single sex toilets for members of their own sex, but also that they should not be left without any toilet provision at all.
OK...
How does that work in practice? There are going to have to be unisex toilets everywhere, aren't there? But there aren't yet.
The other issue I have relates to associations. The guidance confirms it is lawful for an association to restrict its membership to people who share two protected categories, for example, gay men or lesbian women. On a very strict interpretation of this, it would seem that you can't have LGBT associations, or even LGB ones. You could have an association for lesbian women and gay men, because that would be limiting membership to people who share one protected characteristic (being attracted to members of the same sex). Bisexuals have a separate protected characteristic, because being attracted to members of both sexes is listed in a separate category in the legislation. So technically an LGB association would not satisfy the criteria because the B do not share the same protected characteristic as the LG. LGBT associations are even more messy, because T is obviously a completely different protected characteristic to the LGB, and although some T people are also L or G, many of them are heterosexual. So, no shared protected characteristic, does this mean they can't form an association which excludes straight "cisgender" (SORRY!) people?
In reality I am sure that no one is interested in policing people's sexuality or membership of LGBT associations, but I am quite surprised that the EHRC have been this prescriptive in the preliminary guidance, because that will only add fuel to the fire.
