Actually...
I'm not sure it does what you are saying it does.
The judgement seems to be saying that IF the Company wants to sack someone for misbehaving, they have to put us through the D&G. It is already known that they can then sack us afterwards no matter what anyway, but the implication (and kind of referred to in para 75) is that they just need to keep their mouth shut next time they sack 51 pilots, and there isn't anything any of us could do about it.
I'm totally reassured...
