Testimony given as a witness at another hearing of the same or a different proceeding, or in a deposition taken in compliance with law in the course of another proceeding, is not inadmissible under the hearsay rule if: 1. The declarant is unavailable as a witness; and 2. If the proceeding was different, the party against whom the former testimony is offered was a party or is in privity with one of the former parties and the issues are substantially the same.
