Thanks. As I understand it all either party has to do is request a jury trial within the proscribed time limits (which I once posted but have since forgotten) and the Court must grant the request. But the time limits are firm and I don't think the Judge has much wiggle room, certainly not for an explanation like "inadvertently". I'm surprised he has called for oral arguments.
If that's truly all they had to offer I wouldn't expect the Motion to succeed.
