Yes, the wording says something like undergoing or proposing to undergo gender reassignment. But then doesn't even properly define gender reassignment, other than 'changing attributes', which could be interpreted as clothes or anything. But as you have the protected characteristic even if you are just considering it, it's fairly meaningless.
You also don't have to be considering it at all. You can be discriminated against on the basis that someone thinks you are.
Like someone could discriminate against you on the basis that they think you are gay.
What it means is you can't be treated differently to somebody who doesn't have that protected characteristic.
In terms of how that relates to women, if a man has a GRC, the comparator is someone else of their same legal sex. So it would be a woman. If they don't have a GRC, it's a man.
So without a GRC, are you treating this person differently to any other man?
With a GRC, are you to treating this person differently to a woman?
Also, there are still exemptions built in even with a GRC. No-one at all was making a law that said, eg, rape survivors can't choose the sex of their counsellor, men can play women's sports, and rapists can share cells with women.
But the definitions are woolly. I was told that the law often does this deliberately, to leave room for interpretations.
Originally TRAs claimed that a GRC was just an admin issue. But it became quite clear, that the correct interpretation would be that a GRC impacted on which sex a man would be compared with.
Take all Women shortlists, for instance. It could be argued that it was legal for a man with a GRC to be on one, because they were legally female. But a man without a GRC is still legally male and cant be.
Ann Sinnott is seeking legal clarification from the EHRC, the body who is meant to provide guidance about the law.
They have been providing the wrong guidance, and she is demanding the correct interpretation, and proper clarification. Precisely because so many lobby groups are interpreting the law to the huge detriment of women.
If you google her fundraising, she has an easy to understand explanation about it.
