GLP claiming that the EHRC interim guidance was issued in contravention of the proper procedure, misrepresented the SC ruling, and went beyond scope by mentioning employment as well as services.
(As it has been withdrawn, and nobody took a blind bit of notice of it, I don't know what remedy they had in mind.)
In the alternative, if it (and by implication the currently pending guidance) correctly reflects the ruling, then a declaration of incompatibility is sought between EA2010 and the Human Rights Act.
I'm hoping he'll give them the brush off based on the SC being bound by the HRA and him being bound by their ruling. Or maybe he'll reason it all out from first principles, as he's seen evidence that the first instance court in FWS did not?
I'm not sure that he couldn't avoid ruling on the employment issue altogether, because out of scope, but he heard evidence on it, so could find a sex means sex interpretation of the workplace regulations and that they are not incompatible with the HRA (we can hope).
