It always needed to end up on the courts, the capture across the institutions is so complete.
What we're seeing is growing awareness in the legal establishment that the foundation of the legal recognition of gender, the Gender Recognition Act 2004, is fundamentally flawed filled with crap contradictory definitions trying to give something legal force that it should not have and thus the Act was always going to cause chaos down the line.
It didn't for maybe a decade while trans activists began to cotton on to the fact that an unprecedented land grab had opened up to them. When the chaos started to bite, a fantastically effective tactic was rolled out, anyone who said "hang on" got called a "bigot" and also was threatened by activists right across the captured landscape. This had been just about 100% successful until the courts got involved and started to ask "what does this mean?", "how are you seeking to apply this?", etc, and now a complete shitshow is being revealed.
