From the article (and I haven't seen others), it looks like they are planning on two things - firstly, to allow males into women's toilets on council premises, and secondly, to object to the EHRC guidelines.
"Greens councillor Alex Staniforth led the charge," well he would, wouldn't he. Apparently he identifies as non-binary (which I have only just discovered, because after all who would know?) Anyway, he wanted to defund Edinburgh Women’s Aid due to them excluding males from their women-only provision. There is the usual hyperbole, this time from SNP Lesley Macinnes, about "rhetoric and attitudes which have questioned the right of trans people to exist.”
The Tories objected, but of course they are in a minority.
There is a misunderstanding in the article though, which says, "The SNP, Scottish Green and Scottish Lib Dems combined to win this vote and force the Labour council leader to write to the UK Government to demand the guidelines are scrapped. They make it illegal for men to use toilets, changing rooms and service which are female-only." But of course, it's not the guidelines that make it illegal, it's the Supreme Court judgement that clarifies the law and says this is illegal, regardless of whether the guidelines are passed or not.
Yes, slam dunk legal case against the council if they go ahead with this - but someone would have to bring a case.
Incidentally, I notice that the Scottish Daily Express has this article under "News > Politics > Women's Rights" rather than something "trans". Well done them.
