2.04.440 [Rule 41] Attacking and Supporting Credibility of Declarant
When a hearsay statement, or statement defined in Section 2.04.400, Rule 37 (b) (1-4), has been admitted into evidence, the credibility of the declarant may be attacked, and if attacked may be supported, by any evidence which would have been admissible for such purposes had the declarant testified. Evidence of a statement or conduct by the declarant at any time, inconsistent with the declarant's hearsay statement is not subject to any requirement that the declarant may have been afforded an opportunity to deny or explain. If the party against whom a hearsay statement has been admitted calls the declarant as a witness, the party is entitled to examine the declarant on the statement as if under cross examination.
