I read the article earlier today and wondered if the Telegraph hadn't maybe not really understood the issue.
The legal issue would be whether the vacancies were advertised quoting the SSE. If they were then clearly those advertising were attempting to misuse the law.
And from the list of names in the article, it is all the usual suspects (majority Scotland) who for politcal reasons were trying to create a precedent as would be the case with Brighton and Nottingham who have clearly stated that in their eyes TWAW.
I wonder if that bizarre response from the EHRC (quoted by PP) was more to do with who had the upper hand there at the time. Not saying it was, but if it was, it would be a clear indication that institutions set up to supposedly be impartial, and provide guidance can be corrupted when the majority (or perhaps a bullying minority) set the agenda of the organisation to mirror their personal politcs.
If I remember rightly many did write to various institutions in Scotland re ERCC such as funders, charity overseers etc., and none thought there was a problem. But then when the Government is telling you it isn't, or is actively telling you that this is a condition of its funding, it isn't really a surprise.
So it would be good if the EHRC was able to make it clear what the SSE mean.
But even if they do there is nothing to stop those groups who want to, to advertise as being trans inclusive by just not quoting the relevant part of the act.
Just to add, that the real shame is that none of the groups who claim to be the representatives of differing women's services have put out guidance to their member groups to remind them what the law is and how they should implement it.
