Remember the case was about whether his employee was right to dismiss him for his behaviour.
This case was NOT just about his concerns about gender identity but his all round behaviour.
The case could fail on ANY SINGULAR part of his behaviour as a reason for dismissal.
In theory he could be completely in the right about gender identity, but the way he has handled it and his behaviour elsewhere would still mean he would lose.
This judgment does not set a precident, but it will deter others from perhaps challenging when they should - even in clear cut safeguarding cases - which isn't good.
However that does not mean that this guy should have won. There are plenty of problems with his case, not just the fact that he choose to represent himself.
It was fairly evident when he was defending himself that there was an issue and he was unlikely to win.
If he had legal representation, would it have helped him? Possibly. But if he had then lost the situation would be even worse. And it doesn't stop the issue with his homophobic comments.
I get the impression, it isn't just about what he believed though. Its also about the degree to which he seems to have pressured this kid almost to the point of harassment 'out of concern'. That concern might have been very genuine and honest but you can't force a child to change their mind either. He sounds like he was clumsy and very heavy handed in his manner and approach. Coming from a male teacher this is also not ideal to say the least. There is a total lack of sensitivitiy going on in pretty much everything he has said.
It doesn't surprise me to learn that there were GC lawyers who have said that they did speak to him before the case and that he didn't have a winnable case.
