To clarify re EHRC
They have pulled GG up on lack of clarity on their website in how membership criteria are being expressed (I know it's confusing, the whole things a wibbly wobbly world of contradiction).
FPFW's original letter to EHRC is pretty much summarised by their original report fairplayforwomen.com/guide-leaders-call-for-halt/
That was checked by three barristers and five safeguarding experts, all concuring with FP's view. However, that's no guarantee that lawyers at the other end will take the same view, the only way you'd get a ruling one way or the other is through the courts.
EHRC then replied, that letter is not yet in the public domain as work is still on going, however EHRC said GG's website was confusing and they needed to change it re membership criteria - to make it clear they admit girls (sex) and some males (gender reassignement, ie transgirls). Transwomen with a GRC have ALWAYS been able to apply as leaders.
Then a parent also wrote to the EHRC - not sure how much of that correspondence is here.
The two letters are different in tone, and emphasis, and from a first glance, possibly interpretation but both now need going over with a fine tooth comb.
And I know, I know, the thread could run for years with all the permutations of what this all means, but until this whole process has run, it's best not to speculate too much about what the EHRC said or didn't say.
You can see what Dr Nic said about the whole GG affair here: twitter.com/fairplaywomen/status/1043739310325936129
There is no case law in this area, we're in the realm of legal opinion, which basically means one lawyer says this, another bats it back with that. EHRC as you know are a public body charged with INTERPRETING equality law, and helping organisations implement it, so they and their legal experts take a view on what they think the courts would be likely to do, or how they would likely perceive a situation, or what they think the EA permits etc, so the EHRC gives an opinion ...
I haven't read this whole thread, so apologies if I've repeated someone else's replies, busy day so this is a bit of a hit and run post, but the bit from the EHRC that Dr Nic tweeted about is GG's website - that it lacks clarity re membership criteria.
