Regarding (a), I'm not claiming to know either way. Instead, I'm insisting that we don't know, and won't know until something is filed with the court, so we shouldn't claim it will be contested or uncontested.
Regarding (b), if the lawsuit is uncontested, I believe the judge doesn't even get into specifics. They will be canceled by a default judgment. If the share cancellation is contested, however, I'm of the belief that the judge won't cancel the shares absent clear and conclusive proof of fraud.
