That's because that is what they intended.
That's why that whatsapp group went into meltdown.
If they hadn't meant that men with a GRC were "for all purposes! a (legal) women then it wouldn't have been necessary to have within the SSE the grudging admission that maybe, just maybe, there may be occassions (only when proportionate of course) that a service could be just for biological women.
They have never denied this.
This comes up on endless threads. Those who were part of drafting this have confirmed this.
Starmer etc., who are professionally 2 faced are now trying to say well the law has clarified their intentions.
But in fact it was about social engineering so as to move towards self id. By prioritising trans rights over biological rights.
The Supreme Court in ruling that in the EA sex = biology is to make it a protected characteristic with as much status as the others. Not one than can be impinged on by certificate.
No other protected characteristic has to play second fiddle to another one.
And (I assume) that is why the ruling is only in relation to the EA because it is about the conflict between 2 protected characteristics.
And that's why (although Labour doesn't want to talk about it) the EHRC, having been told to provide clear guidelines of single sex services wrote back and said the law is a muddle and the best step is to disapply the GRA / GRC from the EA. (not that it should ever have been there as it is defined as a medical problem)
I suppose it is a sign that in fact Baroness Falkner isn't able to speak as she would like, because otherwise she would be crowing that from a different angle the Supreme Court has confirmed what they recommended. Sadly the SC ruling is less radical and the GRC is still in the EA rather than being got rid of.
There is another thread where some European "experts" write about how in the UK there is this conflict in the EA.
Maybe to counteract the well orchestrated push back against the SC judgement we should start a campaign that the logical next step is to disapply the GRA & GRC from the EA. ie promote something even more radical than the methodical, this isn't logical, process of the SC.
Or start a petition on the Parliament web site?
Although even if it got 100,000 signatures I bet not one MP would turn up to discuss it in a debate.
(as an impartial observer!) it is so obviously the logical next step.
But yes, absolutely Labour always intended for GRC sex to be the same as biological sex.
Which just shows you how long the political class has been captured.
