Donation?
Alpine,
Seeing as how the original imposition arose as a result of Unite's incompetence, the answer is no.
If I was a Unite/BASSA member, I'd be extremely unhappy about the unrealistic approach to negotiations with BA and the subsequent shambolic escalation to IA. I wouldn't be complaining about this particular litigation though, which as I have said above, would appear to have been reasonable in the circumstances.
