People v. Mauyao y Lorenzo
REITERATIONFacts
The Antecedents: The Narcotics Unit of the Western Police District conducted surveillance on Leyte del Sur Street based on phone calls reporting illegal sale of marijuana. A buy-bust operation was conceived. On April 20, 1987, at approximately 6:00 PM, an informant introduced Police Officer (P/O) Ramon Alferos, posing as a drug addict, to the accused-appellant Arturo Mauyao. P/O Alferos requested to buy five tea bags of marijuana and gave two marked P10 bills. The accused-appellant handed over five tea bags and two sticks of marijuana cigarettes. P/O Alferos then identified himself as a police officer and arrested the accused-appellant. P/Sgt. Jimmy Carbonell, who was positioned across the street, assisted in the arrest. The accused-appellant voluntarily surrendered a red clutch bag containing ten more tea bags and four more sticks of marijuana, along with the marked bills and other cash. Procedural History: The accused-appellant was charged with and convicted of selling marijuana by the Regional Trial Court (RTC), which sentenced him to life imprisonment and a fine of P20,000.00. The accused-appellant appealed his conviction. The Petition: The accused-appellant appealed to the Supreme Court, faulting the RTC for giving credence to prosecution witnesses despite alleged inconsistencies, admitting evidence in violation of his constitutional rights, and convicting him without proof beyond reasonable doubt.
Issue(s)
Whether the RTC erred in giving credence to the testimonies of the prosecution witnesses despite alleged irreconcilable inconsistencies and improbabilities. Whether the RTC erred in admitting evidence despite manifest violation of the accused-appellant's constitutional rights. Whether the prosecution failed to prove the guilt of the accused-appellant beyond reasonable doubt.
Ruling
The Supreme Court affirmed the conviction of the accused-appellant, finding that his guilt for drug-pushing was established beyond reasonable doubt. The Court held that minor inconsistencies in the testimonies of prosecution witnesses do not affect their credibility, and that evidence obtained in violation of constitutional rights, while inadmissible, did not form the basis of the conviction.
Ratio Decidendi
On the credibility of prosecution witnesses and alleged inconsistencies: The Court held that the alleged inconsistencies in the testimonies of P/Sgt. Carbonell and P/O Alferos, such as who received the informant's call or the exact distance the team stopped from the suspect's residence, were de minimis and did not affect the substance of their declaration. These minor discrepancies were considered too trivial to impair the credibility of the law enforcement officers, who are presumed to have regularly performed their duties. The Court reiterated the established rule that minor inconsistencies do not destroy but may even enhance the truthfulness of witnesses, as they erase suspicion of a rehearsed testimony. The findings of fact of the trial court, which had the opportunity to observe the witnesses' demeanor, were given great weight and not disturbed absent evident abuse. On the admissibility of evidence and violation of constitutional rights: The Court agreed with the accused-appellant that his signatures on the Receipt of Property Seized, Exhibit E (acknowledging confiscation of marked bills), and the Booking Sheet and Arrest Report were inadmissible in evidence. These were obtained in violation of his right to counsel during custodial investigation, as there was no showing he was assisted by counsel. The Court stressed that any admission wrung from an accused in violation of constitutional rights is inadmissible. However, the Court clarified that these inadmissible documents were not a factor in the accused-appellant's conviction. On proof beyond reasonable doubt: Despite the inadmissibility of certain documents, the Court found that the accused-appellant's guilt was adequately established by other admissible evidence. The prosecution's evidence, particularly the direct testimonies of the apprehending officers who caught him in flagrante delicto during the buy-bust operation, was deemed sufficient. The accused-appellant's denials and his allegation of extortion were not given credence, as they could not prevail over the detailed and unshaken testimonies of the officers who had no apparent ulterior motive. The Court reiterated that the act of drug-pushing, even in a public place, is a clandestine and swift transaction that does not necessarily deter offenders. Therefore, the prosecution successfully proved the accused-appellant's guilt beyond reasonable doubt.
Main Doctrine
The credibility of law enforcement officers in buy-bust operations is generally upheld, and minor inconsistencies in their testimonies do not necessarily impair their credibility. Evidence obtained in violation of constitutional rights, such as during custodial investigation without counsel, is inadmissible, but conviction can still stand if based on other admissible evidence establishing guilt beyond reasonable doubt.
