unless the plaintiff can pierce the corporate veil to get to Rupert or the BOD. If the corporation was legally formed and there was no fraud I suspect the shareholders will bare the loss. Of course they will all be out of pocket for the loss of share value.
If I was defending I would need to read the deposition transcripts of all the officers, directors and vice presidents of plaintiffs and financial experts to try to show plaintiff suffered no damages thereby cutting off punitive damages and leaving only statutory damages if found liable. If no damages jury might even decide no liability despite being pissed at defendant. Plus there is always the potential for a settlement taking into consideration the cost for trial by both parties. They had no contract so I don't think attorneys' fees are in play.
Frankly, I would not be surprised if there are no damages, I doubt that plaintiff lost any business but they can get statutory damages for any finding of liability and if well played, punitive damages, but they'll need to show malice.
