Responding on the Merits Waives Any Service Defect – “It is
well settled that the appearance of a party at the hearing of a motion
and his or her opposition to the motion on its merits is a waiver of
any defects or irregularities in the notice of the motion.” Tate v.
Superior Court, 45 Cal. App. 3d 925, 930 (1975) (citations omitted).
