There has been a lot of discussion online about which toilets transmen can use. Especially due to the part of the judgement which suggests that it may be legal to exclude them from women’s toilets, and they may not be able to legally use the men’s either.
Going back to basics, the protected characteristic of sex in the equality act does not permit discrimination between men and women. However, there is an exception whereby you can discriminate if it is a proportionate means of achieving a legitimate aim. When a service provider uses the exemption, it is generally in order to provide a female only space because that can very easily be shown to be a legitimate aim. The corollary of providing a female toilet is that another toilet is needed for men, thus creating a male toilet. But it was never the original objective to create a male toilet, it is just a result of having created a female one. So on that possibly dodgy reasoning, would it be legal for a service provider to provide one female toilet and one mixed sex toilet? Because if it is then it would appear to solve the transman question. I know there have been plenty of service providers who have thought it perfectly reasonable to convert the women’s toilets to an all gender toilet and keep the men’s as the men’s. I doubt this was ever legal, but would it be legal the other way round? I’m not saying that men would be happy with this as a solution, but frankly, I don’t care given we’ve been expected to put up with the reverse. What I do care about is leaving transmen with no realistic solution.
Hoping those with much more of a handle on this than I do, can shed some light on it.
