People v. Mario Barte y Cabusas
REITERATIONFacts
The Antecedents: On 18 September 1989, the victim was fatally shot at the canteen operated by his family in Tebag, Sta. Barbara, Pangasinan. The prosecution's case rested principally on the eyewitness testimony of the victim's wife, who identified the accused as the shooter and described the circumstances of the incident. She later executed a sworn statement on 21 September 1989. The accused admitted being at the canteen earlier that evening but claimed he left around six o'clock and remained at home until midnight. The prosecution presented expert testimony establishing that the accused was not a licensed/registered firearm holder, and the attending physician testified to the cause of death. The defense offered alibi testimony and a negative diphenylamine (paraffin) test result on the accused. Procedural History: The Regional Trial Court, Branch 44, Dagupan City, on 17 December 1991, convicted the accused of "Murder with Use of Unlicensed Firearm" under Presidential Decree No. 1866 and imposed reclusion perpetua. The accused appealed to the Supreme Court. The Appeal: The Supreme Court, En Banc, affirmed the conviction for Murder but held that the accused could not be convicted for the aggravated offense under P.D. 1866 because the Information did not allege use of an unlicensed firearm. It sustained the penalty of reclusion perpetua and modified the civil awards by adding moral damages of P20,000.00 and death and burial expenses of P10,000.00 to the P50,000.00 civil indemnity.
Issue(s)
Whether the evidence presented is sufficient to convict the accused of Murder beyond reasonable doubt. Whether the positive eyewitness identification by the victim's wife is credible and can outweigh the accused's alibi. Whether the negative diphenylamine (paraffin) test result exonerates the accused or creates reasonable doubt. Whether the accused may be convicted of "Murder with Use of Unlicensed Firearm" when the Information does not allege use of an unlicensed firearm. Whether the factual findings of the trial court should be set aside for caprice, passion or prejudice.
Ruling
The Supreme Court found the accused Mario Barte y Cabusas guilty beyond reasonable doubt of Murder as charged. The Court held that the conviction for "Murder with Use of Unlicensed Firearm" could not be sustained because the Information did not allege use of an unlicensed firearm, and conviction for that specific offense would violate the accused's right to be informed of the nature and cause of the accusation. The sentence of reclusion perpetua as imposed by the trial court was sustained. The Court affirmed the civil indemnity of P50,000.00 and further awarded P20,000.00 for moral damages and P10,000.00 for death and burial expenses, with costs against the accused.
Ratio Decidendi
On Whether the evidence is sufficient to convict of Murder: The Court found that the prosecution proved guilt beyond reasonable doubt. The ruling emphasizes that the testimony of the eyewitness (the victim's wife) was given in a "straightforward, detailed and unequivocal manner" and remained consistent despite extensive cross-examination. Applying prior rulings such as People v. Palicte (G.R. No. 101088) and People v. Amaguin (G.R. Nos. 54344-45), the Court reiterated that a single credible and positive witness is sufficient to sustain a conviction. The Court also noted that the physical circumstances (short distance, adequate lighting, the witness' familiarity with the accused) supported a reliable positive identification. Finally, the Court stressed that without any showing of trial court caprice or arbitrariness, its factual findings must be respected. On Whether the eyewitness identification outweighs the alibi: The Court reasoned that the widow's positive identification demolished the accused's uncorroborated alibi. The opinion observed that for an alibi to prosper, the accused must establish the impossibility of his presence at the scene at the time of the offense, a burden the accused failed to meet. The Court noted that corroborative testimony for the alibi was lacking or ambiguous, and that the accused's residence was only about 50 meters from the canteen, making a return feasible. Citing the witness' vantage point (three to four meters away) and the lighting conditions, the Court found the identification credible. The Court reiterated the established rule that an uncorroborated alibi cannot prevail over positive identification when the latter is credible. On the Probative Value of the Negative Diphenylamine (Paraffin) Test: The Court explained that the diphenylamine or paraffin test is "extremely unreliable in use" and can only establish the presence or absence of nitrates or nitrites on the hand; it cannot conclusively show whether a firearm was discharged by the tested person. The Court cited People v. Mendoza to underscore the test's limitations and accepted the prosecution expert's and defense expert's concession that a person who fired a gun might still produce negative results. Therefore, the negative paraffin test did not create reasonable doubt nor did it overcome the eyewitness identification and other evidence. The Court rejected the defense's inference that a negative test conclusively exonerated the accused. On Conviction for an Offense Not Alleged in the Information (Use of Unlicensed Firearm): The Court held that despite evidence showing the accused was not a licensed firearm holder, the accused could not be convicted of "Murder with Use of Unlicensed Firearm" because the Information never alleged that the firearm used was unlicensed. The Court invoked the constitutional right to be informed of the nature and cause of the accusation (Section 14, paragraph (2), Article III, 1987 Constitution) and ruled that conviction for an offense or aggravating circumstance not charged violates due process. Consequently, the highest offense properly proved and charged was Murder, and the accused was convicted accordingly. On Whether the Trial Court's Findings Should Be Disturbed: The Court refused to set aside the trial court's factual findings for lack of any showing of capriciousness, passion or prejudice. The Court noted that the defense did not impute arbitrariness to the trial court, and that the trial court's evaluation of witness credibility—particularly the consistency and detail of the eyewitness—was entitled to deference. Therefore, the Supreme Court sustained the trial court's findings and conviction as to Murder, modifying only the legal classification of the offense to conform to matters charged in the Information.
Main Doctrine
Positive eyewitness identification, when credible, categorical and consistent, may suffice to sustain a conviction for Murder and may outweigh an uncorroborated alibi; an accused cannot be convicted of an offense or aggravating circumstance not charged in the Information as doing so would violate the constitutional right to be informed of the nature and cause of the accusation against him.
