No bet. In fact, my bet would be that both sides appeal the ruling; the plaintiffs to get the direct claims restored, and the defendants to get even the derivative claims dismissed.
Of course, all this just adds more delays. If Sweeney has to wait for these appeals to be decided before setting a trial date, the parties might not even get their day in court until 2022.
Allowing SCOTUS to rule would be very risky on Treasury's part. I anticipate a settlement of all cases before that can happen. Perhaps by next summer, though I don't know if some plaintiffs will want to see the capital rule before deciding what they'll accept.
Exactly. This is why the statement "No plaintiff has asked for a conversion" is a supposition, not a fact. We don't know what the plaintiffs have asked for, and it's quite likely that they are not all asking for the same things. Coordination is needed.
