Thank you for this summary. I have tried 3 times to extract meaning but there is so much extraneous detail that it defies understanding for the average person! One of the problems is that they don't have one single killer argument and that they are going for a pick and mix mud-slinging attempt in the hope that something sticks? Or it is just a publicity stunt?
Anyway here is my attempt - which I think gets to the same place as you but with a poorer understanding of the law?!
I got as far as understanding that their letter is a pre-action Judicial Review to challenge the EHRC Interim Update guidance. So it is not legal action appealing the Supreme Court judgment. This doesn't seem to be clearly understood over on Reddit. And if a JR is actually launched it would be on process, not outcome, so even if the EHRC process is found to be flawed, that may not affect their actual advice.
So far so good - no legal action on a procedural matter at the EHRC.
Next it seems they are claiming that part of the procedural problem relates to the consultation not including workplace toilets (and only covering services and associations)?
The letter only deals with GRC holders in workplace toilets. They haven't spelled that out to all the people chipping in to the fundraiser but I suppose they consider this a wedge issue so we can go around the genital inspection/toilet police loop again.
The GLP request seems to boil down to
- asking the Secretary of State for Women & Equalities to make the EHRC reverse/re-think their interim guidance - ie withdraw it, OR
- if the Secretary of State agrees that the law has been interpreted correctly that they make arrangements to amend the law to allow trans people to access their facilities of choice.
The sections of law they seem to suggest might need amending by Parliament (if applicable) would be:
- the single sex provisions of the EA and/or
- that tricky section 9 of the GRA "the person’s gender becomes for all purposes the acquired gender" and/or
- the HSE's requirement for separate toilets to be provided for men and women on the basis that the regs don't define male or female.
I can't imagine the Secretary of State will want to open up any of these laws.
Numerically unisex third spaces meets the needs of the largest combined subgroup - 75% of all trans people are non binary plus trans men. It is not in the TRA's interests for this figure to be widely discussed, but if they open up the Workplace Regs that is what will happen...
Is it just me or could this be an own goal?
