Delaware may actually be relatively quick to rule on this. It’s a pretty straightforward breach of contract case, and one side has a much, much stronger position than the other.
Where it’ll get really interesting is if the court orders specific performance (as I expect them to do, if the case makes it to a verdict). Sure, EM has a legal obligation to comply and buy the company, but what if he just….. declines? He obviously doesn’t feel like rules or the legal system apply to him (sometimes for better, but increasingly consistently for worse) but I’m not sure that I see the Delaware chancery court sending men with guns to his front door to seize $44 billion.
