Appeal decisions in the Inner House set a precedent for Scotland and are legally binding there. So this judgement is the new authority on the issue. (Until another Inner House decision sets a different precedent.)
The judges referred to biological not legal sex in their ruling btw, reminding us that the Equality Act defined women as female and did this even though at the time the concept of legal sex had already been created.
I thought I’d seen a reference in the judgment to the PC of sex being about biological sex, but then thought I must have misunderstood - I’m not aware of ‘biological sex’ being a category that is recognised anywhere in legislation; also, given that a trans woman with a GRC is regarded as being a woman - and female - for all legal purposes, they must be regarded as a woman for the purposes of the PC of sex.
I’m not convinced that the use of the term ‘female’ was necessarily intended to indicate a conceptual distinction in the EA between ‘biological sex’ and ‘gender’. It seems to me, in the context it’s used, it might have just been intended to make clear that the use of the terms ‘man’ and ‘woman’ didnt limit those categories to adults.
The GRA includes a provision that, where a person has obtained a GRC, “if the acquired gender is the male gender, the person’s sex becomes that of a man and, if it is the female gender, the person’s sex becomes that of a woman” - so there is clearly no established position in legislation as to what ‘gender’, sex’, ‘male’ and ‘female’ mean.
