Can a judge capriciously cut off testimony at a dissolution hearing?

The matter before us, however, does not involve a judge capriciously cutting off testimony or prejudicially shaping the scope of evidence. Rather, the issue is the whether the trial court here could, in an extremely long-running and contentious dissolution matter, deny a further continuance of a particular hearing under the " 'circumstances presented, particularly in the reasons presented to the trial judge at the time the request is denied.' " (People v. Howard, supra, 1 Cal.4th at p. 1172.)
