What is the test for suppressing evidence in a civil case?

Courts generally order evidence suppressed for two reasons: to ensure a fair trial, and to deter future police misconduct. (See People v. Zamora (1980) 28 Cal.3d 88, 99-100, 167 Cal.Rptr. 573, 615 P.2d 1361.) Neither reason applies here. The witness' descriptions of the videotape evidence were reliable, and the possibility that the tape contained exculpatory evidence was remote. Defendant had the opportunity to inspect the videotape machine and to cross-examine or impeach these witnesses. Thus, admission of their testimony did not deny defendant a fair trial.
