HEARSAY:

     Section 36 of Rule 130 of the Rules of Court provides that witnesses can testify only with regard to facts of which they have personal knowledge; otherwise, their testimonies would be inadmissible for being hearsay Since the witnesses merely attested to the voluntariness and due execution of the respective extrajudicial confessions of the accused, insofar as the substance of those confessions is concerned, the testimonies of the police witnesses are mere hearsay.
