It would be a huge waste of time for both sides to go through the motions of an MtD followed by a nearly inevitable grant of leave to amend. Personally I think they should have not agreed to it and just gone ahead and filed the MtD and opposed the leave to amend, and filed for sanctions on top of that, just on principle but hey, maybe Nick isn't finding that even the dumbest of his Nickers want to fund his luxury lolsuit defense, and Randazza is costly counsel.
In any event, this is the same result that was most likely at much less cost. And remember, Minnesota doesn't have a SLAPP statute. Ironically, SLAPP is intended to reduce litigation but we see what happened in the Vic case. It actually encouraged not just litigating but massively over-litigating a rather simple case.
