I believe you’re correct, they’ve most likely spent a small fortune getting the case to this point. The Filing Date was 10/18/2019, so dragging on for over 2 years now.
I noticed Listermann filed this recently (2 days ago):
02/16/2022 Notice (Of January 31, 2022 Hearing And Court Orders) Filed by Bradley M. Listermann (Plaintiff); Bradley M. Listermann (Cross-Defendant)
