The case by case part didn't feel right though
It is exactly right. The exceptions do not allow blanket discrimination. You have to justify it on an individual basis.
Any GRA reform will not change the protected characteristics in the Equality Act nor the exceptions under the Equality Act that allow provision for single and separate sex spaces
Been saying this since forever.
I am not in a position to do this, I would help, is someone be up for leading a crowdfund to take Marks & Spencer and Topshop along with those that offered the training, to court for the EA2010 sex segregation, putting the dignity, privacy and safeguarding of women and girls at risk?
Not really sure what law you think M+S have broken. The EA2010 protects against discrimination. By allowing transgender people to use the appropriate changing rooms, M+S did not discriminate.
It will be impossible for a service provider to prove someone IS trans. On paper ALL their official documentation will match that of a natal female. We cant exclude on the basis of trans if we can’t confirm someone IS TRANS.
If you are unsure if someone is trans then it will never be proportionate to exclude them. If you know they are trans, but cannot prove it, and it is justified, then discriminate against them. If they are not trans then there is no liability. And if they are trans, then it fits into the exception.
And the organisation cannot ask if people have a GRC
Yes it can. But if you have a need to know someone's legal gender then it is good practice to ask for a birth certificate instead.
EA says there are sex exceptions even though they are useless
Not useless, they do the job. If you really need to discriminate you can. But casual bigotry is not allowed.
