What is the test for admitting a statement made by a witness in a civil case?

In California, "[e]vidence of a statement by a declarant having sufficient knowledge of the subject is not made inadmissible by the hearsay rule if the declarant is unavailable as a witness and the statement, when made, ... so far subjected him to the risk of ... criminal liability ... that a reasonable man in his position would not have made the statement unless he believed it to be true." ( 1230.) The proponent of such evidence must show that the declarant is unavailable, that the declaration was against the declarant's penal interest when made and that the declaration was sufficiently reliable to warrant admission despite its hearsay character. (People v. Lucas (1995) 12 Cal.4th 415, 462, 48 Cal.Rptr.2d 525, 907 P.2d 373.)
