Section 133 - Credibility of declarant

Where hearsay evidence is admitted,

(a) evidence of a statement or other conduct by the declarant that is inconsistent with the declarant’s hearsay statement is not inadmissible for the purpose of attacking the credibility of the declarant though the declarant did not have an opportunity to explain or deny the inconsistency because the declarant was not called as a witness, and

(b) any other evidence offered to attack or support the credibility of the declarant is admissible if it would have been admissible had the declarant been a witness in the action.
