The law, however, provides for specific exceptions to the hearsay rule. One of the exceptions is the entries in official records made in the performance of duty by a public officer. In other words, official entries are admissible in evidence regardless of whether the officer or person who made them was presented and testified in court, since these entries are considered prima facie evidence of the facts stated therein. Other recognized reasons for this exception are necessity and trustworthiness. The necessity consists in the inconvenience and difficulty of requiring the official's attendance as a witness to testify to innumerable transactions in the course of his duty. This will also unduly hamper public business. The trustworthiness consists in the presumption of regularity of performance of official duty by a public officer.
Exhibit “A,” or the Certification of the PRC dated 17 January 1998, was signed by Arriola, Director II of the PRC, Manila. Although Arriola was not presented in court or did not testify during the trial to verify the said certification, such certification is considered as prima facie evidence of the facts stated therein and is therefore presumed to be truthful, because petitioner did not present any plausible proof to rebut its truthfulness. Exhibit A is therefore admissible in evidence (People of the Philippines Vs. Rosario "Rose" Ochoa, G.R. No. 173792. August 31, 2011).
