I don't think that Fife will be punished by the ET for breaking workplace changing room regulations and sex-discrimination law. They could point out that, even post-Haldane, the precedent of Croft v Royal Mail has led to widespread treatment of non-grc holders who 'make an effort' as honorary legal females, and there are plenty of lawyers willing to give Counsel's Opinion that this is all fine (SC ruling of course now says it's not fine and never was).
It's too big a topic for the ET, which is more about the conduct of relationships.
They punished SP, without due process, for expressing WORIADS views.
They subjected her to a hostile and degrading environment and did not investigate her complaint.
Even if most people believe TWAW, failing to accommodate her non-belief put her in much the same position as a Muslim who is being persecuted by his workmates with relentless pranks involving pork sausages.
Dr Beth still thinks you are an uneducated bigot. Pork is really beef, and Muslims should be forced to eat a pork sausage every day.
