TL;DR

The Supreme Court ruled that a handwriting expert from the PNP, presented as a witness to contest the authenticity of a deed of donation, should not have been disqualified by the lower court. The Court emphasized that witness disqualification must adhere strictly to the grounds specified in the Rules of Evidence and that excluding relevant expert testimony constitutes grave abuse of discretion. This decision underscores the importance of allowing qualified expert witnesses to present their findings and opinions, as it can significantly contribute to a fair and just resolution of cases involving document authenticity and potential forgery.

The Signature Showdown: Can an Expert Witness Be Silenced?

The case revolves around a disputed Affidavit of Transfer of Real Property, which the heirs of the late Dr. Andres Navarro, Jr. used to claim exclusive ownership of a 108-hectare property in Masbate. Luisa Navarro Marcos, sister of the deceased, challenged the authenticity of the affidavit, alleging that the signature of her father, Andres Navarro, Sr., was a forgery. This challenge led to a legal battle where the admissibility of expert testimony became a central point of contention, ultimately reaching the Supreme Court.

At the heart of the matter was the Regional Trial Court’s (RTC) decision to disqualify PO2 Mary Grace Alvarez, a PNP handwriting expert, from testifying. The RTC reasoned that her testimony would be hearsay and that the handwriting examination was unauthorized. However, the Supreme Court found that the RTC committed grave abuse of discretion by disqualifying PO2 Alvarez because she possessed the necessary qualifications and none of the disqualifications specified under the Rules of Court. The court emphasized that the RTC confused the qualification of the witness with the credibility and weight of her testimony.

The Supreme Court referenced Section 20, Rule 130 of the Rules on Evidence, highlighting that “all persons who can perceive, and perceiving, can make known their perception to others, may be witnesses.” It also cited specific rules of witness disqualification provided under Sections 21 to 24, Rule 130 of the Rules on Evidence, emphasizing that mental incapacity, marriage, death or insanity of the adverse party, and privileged communication are exclusive grounds for disqualification. Building on this principle, the Court reiterated its stance in Cavili v. Judge Florendo, that “the specific enumeration of disqualified witnesses excludes the operation of causes of disability other than those mentioned in the Rules.”

The Court further clarified the role of expert witnesses, citing Section 49, Rule 130 of the Rules of Evidence, which states that “the opinion of a witness on a matter requiring special knowledge, skill, experience or training which he is shown to possess, may be received in evidence.” The Court also referenced the case of Tamani v. Salvador, where the testimony of a PNP document examiner was crucial in determining the authenticity of a signature. The Supreme Court then used the Tamani v. Salvador case to emphasize that the value of a handwriting expert’s opinion lies in their ability to point out distinguishing marks and discrepancies that an untrained observer would miss.

The Court stressed that it disagreed with the RTC’s assessment that PO2 Alvarez’s testimony would be hearsay. The Court explained that under Section 49, Rule 130 of the Rules on Evidence, PO2 Alvarez is allowed to render an expert opinion, as the PNP document examiner was allowed in Tamani. The Supreme Court concluded that the RTC should not have preemptively ruled PO2 Alvarez’s testimony as hearsay, especially before she was given the opportunity to testify and present her findings. Therefore, the CA should have issued a corrective writ of certiorari and annulled the RTC ruling.

In conclusion, the Supreme Court’s decision emphasizes the importance of adhering to the established rules on witness qualification and the potential value of expert testimony in resolving factual disputes. By setting aside the disqualification of the handwriting expert, the Court safeguarded the petitioner’s right to present relevant evidence and ensured a fairer and more thorough examination of the contested deed of donation.
