What is the effect of an unlawful detainer action on the underlying case?

Appellants further contend the unlawful detainer action should not affect the underlying case because they did not receive a full and fair hearing before the court ruled in the unlawful detainer proceeding. According to appellants, they were forced to trial before their demurrer was ruled on and before they answered the complaint. Again, this issue has already been decided against appellants. The appellate division of the superior court rejected this argument and affirmed the unlawful detainer judgment on appeal. Accordingly, this claim is barred. (Vella v. Hudgins (1977) 20 Cal.3d 251, 256-257.)

4. The trial court properly denied appellants' request for judicial notice.
