Slightly different take: this is Chupp trying to outsource the proper disposition of TCPA.
Chupp realized after the hearing that everything was fucked, but he already made some rulings, and couldn't come up with anything consistent. Mediation was a long shot that no one had faith in.
So he blanket dismissed everything, and (reasonably) figured the stuff that should have passed TCPA would come back down from appeals. No need for reasoning, citations, or following the intricacies of the TCPA; that becomes someone else's problem, and he'll get back a list of "proper" causes of action to proceed on.
I didn't think this accusation was supportable based on what we had before now, but this ruling is pretty blatantly passing the buck. It doesn't make sense for him to write out a full justification for his rulings, since appeals are de novo review and that second look is inevitable.
You can read this as Chupp trying to "do the right thing" and get a corrected suit going, but it's still him not putting in the work to do this properly at the trial level.
