The process would make a few lawyers VERY rich, though!
But doesn't the loser pay the costs? From past history it would seem that the BA lawyers are rather more switched on than those of Unite.
Or does it now put WW in the position of saying to Unite, "sort your branches (BASSA & CC89) out or we'll cripple you financially"?
I believe that WW used this tactic on BALPA after the Open Skies case. BALPA had to agree to be nice, in exchange for WW calling off the lawyers.
