The purpose of discovery is to take the “game” element out of trial preparation by enabling the parties to obtain evidence necessary to evaluate and resolve their dispute before a trial is necessary. Weil and Brown, Cal. Prac. Guide: Civil Procedure Before Trial (TRG 2018) ¶8:1 citing Greyhound Corp. v. Superior Court (1961) 55 C.2d. 335, 376.
Serving “[a]ppropriate written interrogatories are one of the means to accomplish the general goals of the discovery process designed to facilitate a fair trial.” (Juarez v. Boy Scouts of America, Inc. (2000) 81 CA4th 377, 389)
“Interrogatories expedite the resolution of lawsuits … [by detecting] sham claims and defenses … [and] may be employed to support a motion for summary judgment or a motion to specify those issues which are without substantial controversy.” Deyo v. Kilbourne (1978) 84 CA3d 771, 779
