What is the test for an allegation of false testimony in a civil case?

Evidence Code section 1221 provides for adoptive admissions and states, "Evidence of a statement offered against a party is not made inadmissible by the hearsay rule if the statement is one of which the party, with knowledge of the content thereof, has by words or other conduct manifested his adoption or his belief in its truth." "Under this provision, 'If a person is accused of having committed a crime, under circumstances which fairly afford him an opportunity to hear, understand, and to reply, and which do not lend themselves to an inference that he was relying on the right of silence guaranteed by the Fifth Amendment to the United States Constitution, and he fails to speak, or he makes an evasive or equivocal reply, both the accusatory statement and the fact of silence or equivocation may be offered as an implied or adoptive admission of guilt." [Citation.] 'For the adoptive admission exception to apply, . . . a direct accusation in so many words is not essential. [Citation.]' 'When a person makes a statement in the presence of a party to an action under circumstances that would normally call for a response if the statement were untrue, the statement is admissible for the limited purpose of showing the party's reaction to it. [Citations.] His silence, evasion, or equivocation may be considered as a tacit admission of the statements made in his presence.'" (People v. Riel (2000) 22 Cal.4th 1153, 1189.)
