Sorry, I am late back to this.
Recently we have used the new EHRC guidelines to bolster our 'case by case' decisions.
We decided that the case of a transwoman, born male, male bodied, was one we would deem unsuitable for inclusion in our service. We therefore would reject any and all applications by transwomen in the same basis as we reject applications from all other men. And we would signpost them to other services, even offering transport, food, clothing as we do so.
We had already revisited our T+C's a couple of years ago, when we had our one and only transwoman applicant. At that time we asked our incumbent clients what they thought and they all said no. We thought that was 'case by case' but were told, quite forcibly, by one woman, solicitor, victim of DV, that we were wrong and were in danger of traumatising our clients if we carried on in that vein.
The upshot was we changed our policies and she now works for us sometimes.
But it took her anger to make us realise that we had simply gone along with an incorrect interpretation of 'case by case', as given to use by the LA. They too are now looking again, though they never did have the sex and gender confusion they were quite vociferous about inclusivity. They seem to be having a rethink.
So I do have hope...
