Following on TT. Why mention someone with a GRC? We know it didn’t change the law then or now as to male access to female single sex spaces. Even at that, I don’t think he had a GRC anyway.
To be fair, until the Supreme Court judgement of 16th April, there was confusion about the position of someone with a GRC. Whether someone with a GRC could use single sex facilities required under Health and Safety regs, was something which was worth clarifying. Now we know the answer is No.
