The fictional situation is that a wrongful death claim is filed outside the 2-year statute of limitations, but a corrupt judge has extended the statute of limitations in order to benefit the plaintiff. My question is, how would the defendant challenge the ruling so the suit can't go forward?
So...the lawsuit is filed beyond the SOL. If the expiration of the SOL appears on the face of the complaint, the defendant would, presumably, attack the complaint by filing a motion to dismiss (assuming the case is in Texas, it would be done pursuant to the Texas equivalent of
Rule 12(b)(6) of the Federal Rules of Civil Procedure). If the court denied the motion, then the case would proceed unless the defendant sought an interlocutory appeal. If the defect is not apparent from the face of the complaint, then the defendant might try to make a motion for summary judgment. If the court denied the motion, then, again, the case would continue. If the plaintiff then won at trial, the defendant would appeal. Note that interlocutory appeals are generally disfavored.
Since this is fiction, the more drama the better.
Sorry, but there is little to no "drama" involved in civil motion practice.
Don't some of these cases take a long time to settle?
Not sure what "these cases" means, but yes, cases can be pending for a long time before settlement or resolution.
the judge is corrupt, but his stated reason for the extension is that the defendant left the state and changed her name. But that's a contrived reason since it's easy enough to find someone these days. The unstated reason is that the defendant is wealthy now (was indigent before), so there's something to gain by suing her.
The judge might be corrupt, but that reasoning isn't at all "contrived" b ecause
the defendant's absence from the state tolls the statute of limitations, so what you're describing is a proper ruling. Also, while it might be easier to find folks now as compared to, e.g., 40 years ago, that doesn't mean it's "easy" to find someone who has moved and changed her name. However, at the end of the day, the name change isn't relevant.
Another way to solve this might be that the corrupt judge is recused from hearing the case at the last minute
Why?
and an honest judge steps in and dismisses it because the defendant (main character of the novel) is clearly not guilty of wrongful death (criminal charge was previously dropped).
Ever hear of O.J. Simpson? He was charged with murdering his ex-wife and another person. He was acquitted and then sued for wrongful death by the survivors of the two deceased persons, and Simpson was found civilly liable (there is no "guilty" or "not guilty" in civil court) for wrongful death. This illustrates that criminal charges being dropped does
not make a person "clearly not [liable for] wrongful death."
if a judge gets sick or is called away, is it likely they could keep the scheduled hearing if another judge is available?
Possible? Sure. How likely or unlikely it is depends on particulars of the given courthouse.
