(b) Except as provided in subdivision (c), the grand jury shall not receive any evidence except that which would be admissible over objection at the trial of a criminal action, but the fact that evidence that would have been excluded at trial was received by the grand jury does not render the indictment void where sufficient competent evidence to support the indictment was received by the grand jury.

(c) Notwithstanding § 1200 of the Evidence Code, as to the evidence relating to the foundation for admissibility into evidence of documents, exhibits, records, and other items of physical evidence, the evidence to support the indictment may be based in whole or in part upon the sworn testimony of a law enforcement officer relating the statement of a declarant made out of court and offered for the truth of the matter asserted.
