A statement within the scope of an exception to the hearsay rule is not inadmissible on the ground that the evidence of such statement is hearsay evidence if such hearsay evidence consists of one or more statements each of which meets the requirements of an exception to the hearsay rule.

Evidence of a statement or other conduct by a declarant that is inconsistent with a statement by such declarant received in evidence as hearsay evidence is not inadmissible for the purpose of attacking the credibility of the declarant though he is not given and has not had an opportunity to explain or to deny such inconsistent statement or other conduct. 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 at the hearing. For the purposes of this section, the deponent of a deposition taken in the action in which it is offered shall be deemed to be a hearsay declarant.

Section 1203 is not applicable if the hearsay statement is offered at a preliminary examination, as provided in Section 872 of the Penal Code.

A statement that is otherwise admissible as hearsay evidence is inadmissible against the defendant in a criminal action if the statement was made, either by the defendant or by another, under such circumstances that it is inadmissible against the defendant under the Constitution of the United States or the State of California.

Nothing in this division shall be construed to repeal by implication any other statute relating to hearsay evidence.
