None of these legal cases are going to produce good case law until it is established what a man or a woman is.
The judgement refers, in essence, to the expression of a gender critical belief as being hostile to the dignity of a transperson and hurtful without considering whether the hurt felt by a transperson is reasonable. I could argue that I find the belief that certain religions condemn me to hell as a non believer harmful but given that I don't believe there is a hell, how can my hurt be real or reasonable ? Maya is being held to account by the Judge for not being nice enough.
Similarly, if I want to argue that I've been discriminated against as a Christian, I must first satisfy the court that I am actually a Christian. How do we do that if there is not an accepted basis for determining what a Christian is ?
If a transwoman is going to argue that they are discriminated against, how are they going to prove their trans status ? If a transwoman is going to argue that there is scientific evidence , then surely they need to provide evidence that they personally fit within those scientific parameters, whatever they may be ? Otherwise we're back to woman being a feeling or simply a belief itself with no sound, measurable or demonstrable traits.
Employment tribunals have a tendency towards the left and identity politics. Their judgements are frequently appealed and over ruled. Until there is a case taken to the Supreme Court the fight isn't over.
