I would agree with this if it wasn't a TCPA hearing. It would be prudent to take the oral rulings as wrote until the written rulings are filed.
The fact there is no filed ruling and the mediation order requires ALL parties to partake does indicate his rulings are not final.
In any other civil case his word would have been absolute, but Anti-SLAPP is a different beast entirely. From the looks of it, the TCPA takes absolute precedence here and dictates what an official ruling is. (It's also unconstitutional as shit because it specifically dictates that the Court deny the Plaintiff their right for a Civil Jury trial if they don't meet the "Prima Facie" requirements, which is subjective as hell. This is why the 7th Amendment exists. Pretty damn straightforward amendment that everyone, including the states, tends to forget. If the TCPA was decided via Jury, it would satisfy this amendment.)
Specifically I also want to question that the divorce in this case law is a ruling or a decree? Decrees are treated differently in other states. Also this isn't a "Trial Court" yet. A Verdict is WAY harder to appeal than a Ruling.
When a Jury makes a decision, the judgement is practically final with an exception of a mistrial or the judge nullifies the verdict.
Oh I know their appeal would be fucked, but it's still a damn time sink.
