In Edgardo Postanes v. People of the Philippines, the Supreme Court ruled that a medical certificate must be properly authenticated to be considered as valid evidence in court. The case clarifies that without proper authentication, the medical certificate lacks probative value. This emphasizes the importance of ensuring documentary evidence is adequately supported to substantiate claims in legal disputes.
When Medical Proof Hinges on Proper Authentication
This case arose from two consolidated criminal cases involving charges and countercharges of slight physical injuries between Edgardo Postanes and Remigio Pasion. The Metropolitan Trial Court (MTC) initially convicted Postanes, a decision affirmed by both the Regional Trial Court (RTC) and the Court of Appeals (CA). Postanes appealed, alleging that the CA unfairly discriminated against him by admitting Pasion’s medical certificate while rejecting his own. Central to the dispute was whether the medical certificates presented by both parties were admissible as evidence, given that the physicians who issued them did not testify to authenticate their contents.
The petitioner contended that both his medical certificate and that of the private complainant, Remigio Pasion, suffered from the same evidentiary defect, as neither were authenticated by the issuing physicians. The trial court, and subsequently the appellate court, admitted Pasion’s certificate because it was authenticated by the records custodian from the Philippine General Hospital, while the petitioner’s certificate lacked such validation. This authentication provided a basis for the courts to consider Pasion’s document as credible evidence, a standard not met by Postanes’s submission. The contrast highlights a critical aspect of Philippine evidence law: documents, especially those used to prove physical injuries, must undergo a process of authentication to be considered valid by the courts.
The Supreme Court, in affirming the lower courts’ rulings, emphasized the importance of adhering to the rules of evidence. Philippine law requires that private documents, such as medical certificates, be authenticated to establish their genuineness and due execution. This is generally achieved through the testimony of the person who executed the document, or by someone familiar with their handwriting or signature. In this case, the authentication of Pasion’s medical certificate by the records custodian allowed it to be given probative weight. The petitioner failed to provide similar authentication, thus his medical certificate was deemed inadmissible.
The Court reiterated that factual and credibility issues are not appropriate for a petition for certiorari under Rule 45, where only questions purely of law may be raised. Because Postanes was essentially contesting the factual findings and the assessment of witness credibility by the lower courts, the Supreme Court found no basis to overturn the appellate court’s decision. The court emphasized that absent a showing of grave abuse of discretion, the factual findings of the trial court, as affirmed by the Court of Appeals, are generally binding and conclusive. Therefore, it reiterated that the absence of authentication rendered the petitioner’s medical certificate without probative value, justifying its exclusion as evidence.
This case underscores the critical role of proper documentation and authentication in legal proceedings. Litigants must ensure that their evidence is not only relevant but also admissible under the rules of evidence. Failing to properly authenticate a document can render it useless, regardless of its potential value to the case. Thus, parties should prioritize presenting evidence in a manner that complies with legal standards to effectively support their claims and defenses in court. By ensuring that evidence is authenticated, parties enhance the credibility and reliability of their submissions, increasing the likelihood of a favorable outcome.
