Not really.
What she said was:
The agreements are not legally enforceable on employees individual contracts. So she had to rule for BA. BUT if they had been legally enforceable, then there was a lot going to the Cabin Crew position. However this was not relevant, due to agreements not being legally enforceable. The sections you quote from fall into the discussion of the position had the agreements been legally enforceable.
Or at least that is my take on this.
And I'm still at awe at some comments, such as:
Not all judges agreed, when 1 wrote it, and the other two agreed with her!
BA are paying Unites legal bill as BA got costs! when this means BA can claim their costs from Unite.
So BA won. BA even won costs (best they could get in a case like this, for "close" cases they generally don't award costs). Unite didn't signal they intend to appeal, so no leave to appeal given. (although given the latest offer with "drop all legal action" means it would be hard from them to appeal (start new legal action) and keep the offer)
Really looking forward to reading the "How it was won from my garden" - a fantasy by DH.
