Honestly, his best bet to avoid a massive ass reaming (Though still obtain one, cause that is unavoidable) is to void it all, stating that the hearing itself was so mishandled by him that it cannot stand, but because of the nature and requirements of TCPA he cannot do a do over himself and instead has to have it kicked to appeals.
This will at least forstall the appeals court screaming at him. as he'd be acknowledging his fuckup. It doesn't STOP it entirely, but that's because he put himself in an untenable situation where by every single party could appeal on legit grounds, and he can do nothing to actually FIX that because the deadlines for TCPA stuff are hardset.
Edit: Also, today or monday. It... isn't exactly clear when.
