ELPEDIO RUEGO vs. PEOPLE OF THE PHILIPPINES AND ANTHONY M. CALUBIRAN

The Court held that for a fractured or lost tooth to qualify as serious physical injuries under Article 263(3) of the Revised Penal Code, the prosecution must establish that the injury resulted in a permanent and visible physical deformity that medical intervention could not remedy. Where a fractured tooth is successfully repaired through modern dental procedures and leaves no apparent disfigurement at trial, the offense constitutes slight physical injuries under Article 266(1).

On September 5, 2005, in Iloilo City, petitioner Elpedio Ruego confronted Anthony M. Calubiran and struck him in the face, fracturing his upper right central incisor. The prosecution alleged the punch was unprovoked, while Ruego claimed he acted in self-defense after Calubiran stared at him and initiated physical contact. Medical examination confirmed the tooth fracture, which the PNP medico-legal officer opined caused permanent deformity requiring extraction. The fractured tooth was later replaced through modern dental procedures, and Calubiran presented the repaired tooth during trial. The incident escalated to criminal charges under Article 263(3) of the Revised Penal Code for serious physical injuries, triggering a multi-tiered adjudication of whether a medically remedied dental injury satisfies the statutory requirement of permanent deformity.

• On September 5, 2005, at approximately 10:30 p.m. along Paho Road, Barangay South Fundidor, Molo, Iloilo City, petitioner and his group encountered Calubiran, who was waiting for a jeepney with companions.
• Prosecution witnesses testified that petitioner approached Calubiran, asked, "[guina] kursunadahan mo kami?" (You took interest in us?), and immediately punched him. Sangguniang Kabataan Chair June Alfred Altura attempted to intervene, but petitioner ignored him and continued the confrontation.
• Police and barangay officials arrived after petitioner's group had departed. Calubiran and a barangay kagawad reported the incident to the PNP.
• Dr. Owen Jaen Libaquin, the PNP medico-legal officer, examined Calubiran and documented a fractured upper right central incisor, along with head injuries. Dr. Libaquin opined that the fracture caused permanent deformity and necessitated tooth extraction.
• During trial, Calubiran presented the affected tooth, which the trial court noted had already been repaired through modern dental technological procedures not fully detailed in the evidence.
• In his defense, petitioner testified that he was accompanying a friend home when Calubiran stared at him. Petitioner claimed he asked, "[a]no tulok mo?" (What are you looking at?), after which Calubiran, allegedly intoxicated, threw the first punch. Petitioner stated he retaliated, and both were pacified by bystanders.
• The MTCC found petitioner's self-defense claim uncredible, noting petitioner admitted to uttering the provocative phrase first and lacked defensive wounds. The trial court convicted petitioner of serious physical injuries under Article 263(3), relying on People v. Balubar to classify the tooth fracture as permanent deformity.
• The RTC and CA affirmed the conviction, finding no evidence of victim instigation and agreeing that the loss of a front tooth causing permanent physical deformity falls within Article 263(3).

• Petitioner maintained that Calubiran was intoxicated and instigated the altercation, warranting application of the equipoise rule.
• Petitioner argued that a fractured tooth, which was not extracted and was subsequently repaired through dental procedures, does not constitute "deformity" or "loss of a body part" under Article 263(3) of the Revised Penal Code.
• Petitioner contended that the prosecution’s acknowledgment of a fistfight implied mutual agreement to fight, negating sole aggressor liability and justifying acquittal under the equipoise principle.

• The Office of the Solicitor General countered that Article 263(3) encompasses injuries that nature cannot mend, and criminal liability attaches regardless of subsequent artificial repair.
• Citing People v. Balubar, the OSG argued that a fractured front tooth causing permanent physical deformity falls squarely within serious physical injuries, and the offender is not relieved of liability because the victim can minimize disfigurement through dental procedures.
• The OSG asserted that petitioner was the sole aggressor, as established by witness testimony and petitioner's own admission, rendering the equipoise rule inapplicable.

• Procedural Issues: Whether questions of fact may be entertained in a Petition for Review on Certiorari under Rule 45 of the Rules of Court in a criminal case where the conviction is challenged on evidentiary and factual grounds.
• Substantive Issues: Whether a fractured and subsequently repaired tooth constitutes "deformity" or "loss of a body part" under Article 263(3) of the Revised Penal Code, thereby warranting a conviction for serious physical injuries rather than a lesser offense.

• Procedural: The Court held that while Rule 45 generally restricts review to questions of law, criminal appeals open the entire case for comprehensive review. Because the constitutional presumption of innocence and the requirement of proof beyond reasonable doubt are paramount, the Court is compelled to evaluate factual findings and evidence to prevent miscarriages of justice. Accordingly, the Court entertained the factual challenges regarding instigation and injury classification.
• Substantive: The Court ruled that a fractured tooth does not automatically constitute serious physical injuries under Article 263(3). The Court modified the conviction to slight physical injuries under Article 266(1). It reasoned that modern dental science allows for the complete restoration of teeth, meaning a fracture does not inherently cause permanent disfigurement. Because the trial court observed that the tooth was already repaired via modern procedures and no visible disfigurement was presented, the statutory requirement of permanent deformity was not met. The Court imposed arresto menor, noting that the trial court may, upon application, substitute community service under Republic Act No. 11362.

• Revisitation of the Balubar Doctrine on Dental Injuries — The 1934 ruling in People v. Balubar held that the loss of teeth constitutes a permanent disfigurement under Article 263(3), irrespective of subsequent artificial replacement. The Court expressly declined to continue upholding this rationale, holding that advances in dental science render tooth loss or fracture medically remediable. Consequently, a tooth injury only qualifies as serious physical injuries if it results in a permanent, visible deformity that medical intervention cannot fully correct; otherwise, it warrants a lesser penalty under Articles 265 or 266.
• Equipoise Rule — The equipoise rule dictates that when inculpatory facts support two equally plausible explanations consistent with innocence and guilt, the constitutional presumption of innocence prevails. The Court found the rule inapplicable because the evidence was not evenly balanced. Petitioner admitted to instigating the confrontation, lacked defensive wounds, and was contradicted by witnesses who identified him as the sole aggressor, thereby satisfying proof beyond reasonable doubt.

• "Serious physical injuries contemplate physical deformity or the loss of a body part resulting in the alteration of one's physical appearance. The loss of a tooth, may, in most cases, be later repaired or replaced with an artificial tooth by a competent dentist. Thus, for the loss of a tooth to be considered within the scope of serious physical injuries, the circumstances surrounding its loss and whether it caused a physical deformity or permanent alteration of one's physical appearance must be examined on a case-to-case basis." — The Court established the analytical framework for evaluating dental injuries under Article 263(3), emphasizing that modern medical remediation defeats the presumption of permanent deformity.
• "It is inequitable for this Court to arbitrarily apply the Balubar doctrine in all cases where a tooth has been chipped or fractured and then later medically repaired in a manner where no visible deformity could be seen." — The Court justified departing from nearly a century-old precedent by aligning penal classification with contemporary medical realities and the Revised Penal Code's statutory gradation of penalties.

• People v. Balubar, 60 Phil. 698 (1934) — Cited as the controlling precedent that originally classified tooth loss as serious physical injuries. The Court distinguished and expressly declined to follow its rationale, holding that advances in dental science render the Balubar doctrine obsolete for cases where the injury is medically repaired without visible disfigurement.
• People v. Urzais, 784 Phil. 561 (2016) — Cited to define the equipoise rule and explain its inapplicability to the instant case, as the evidence clearly established the petitioner as the sole aggressor.
• Ferrer v. People, 518 Phil. 196 (2006) — Cited to support the recognized exception to Rule 45, establishing that criminal appeals open the entire case for review and allow the Court to correct factual errors even if unassigned.
• People v. Oh Suilay, G.R. No. 40699 (1934) — Cited as historical precedent where the loss of two teeth was classified as less serious physical injuries, reinforcing the Court's position that dental injuries do not automatically warrant the gravest physical injury penalties.

• Article 263(3), Revised Penal Code — The substantive provision defining serious physical injuries. The Court interpreted "deformity" and "loss of any other part of his body" to require permanent, visible alteration not remediable by medical intervention, thereby excluding successfully repaired fractured teeth.
• Article 266(1), Revised Penal Code — The provision penalizing slight physical injuries. The Court applied this provision to downgrade the conviction, as the injury required medical attendance but did not cause permanent visible deformity.
• Rule 45, Section 1, Rules of Court — The procedural rule limiting petitions for review on certiorari to questions of law. The Court applied recognized exceptions in criminal cases to review factual findings and ensure compliance with the presumption of innocence and proof beyond reasonable doubt.
• Republic Act No. 11362 (Community Service Act), Section 3 — The statute allowing community service in lieu of arresto menor or arresto mayor. The Court noted its applicability, directing the trial court to consider community service upon the petitioner's application.
