When Unite tried to obtain an injunction to stop the crew changes, I think they told the court they had assets of about £170million of thereabouts (and presumably not all of that is in cash).
So Unite has spent £1.2m on this case. It will be on the hook for at least £2m+ of BA's legal costs. Then there is the money they've spent in their previous two court appearances. Plus the money they will have to spend on paying strikers and what they've spent on racecourse venues etc.
Is Unite really going to fund another appeal on this case?
