Wow very interesting. Thank you for sharing, I now understand the equality act a little better.
Here is the direct link to the article, not via Twitter (although if you are on twitter I imagine it's a good thing to repost it)

In discrimination cases ( I have now learnt) there needs to be a comparison - a comparison with someone who does not hold the same protected characteristic, but the comparison needs to be materially the same in every other way.
In this NHS case the judgement was made by comparing the mid transition 'transwoman' to a 'ciswoman'. This is an incorrect comparison...
In short: the correct comparator for a trans-identified male who does not have a GRC, and is claiming gender reassignment discrimination, is a male who does not identify as trans.
The correct comparator is a person who does not have the protected characteristic of gender reassignment. But the comparator should be the same in all other material respects. So if the claimant is male, the comparator must also be male.
...
The flaw in the tribunal’s reasoning is obvious once we consider the question the tribunal should have asked:
Was Mrs Hawkshaw likely to have been concerned about a non-transgender male in a state of undress while using the women’s changing room?
Well of course she would. Because it was a women’s changing room, and the non-trans male comparator is… male.
I do hope they appeal.
