As someone who knows a lot of lawyers, I posed this question back when it changed because I was so ****ed. It seems as if it's certainly possible however no one would win. Even if you could go after individuals rather than ALPA itself, what would we be trying to get back in damages? How could damage be quantified? A lot of assumptions would have to be made about career progression, pay rates, potentially losing a medical...
Bottom line hear is that the lawyers would win as the fees would be astronomical as they'd have to look at so many angles to make the appropriate argument and even if a judgement was obtained against DW or ALPA, the funds wouldn't be there to pay anyway as we'd just be robbing ourselves.
I just hope that we can remove anyone that was involved in that decision.
