People v. Rubio
REITERATIONFacts
The Antecedents: A confidential informant reported to the police that Feliciano Rubio y Alcobendas was selling marijuana at a billiard hall. Police conducted a week-long surveillance, identified the accused, and marked P20.00 in four P5.00 bills to be used by the informant to buy marijuana. On July 24, 1981, at around 11:00 PM, the informant approached the accused, paid him the marked bills, and received a small plastic bag of marijuana. Immediately after, police apprehended the accused, frisked him, and recovered the marked money along with two more plastic bags of marijuana from his pants pocket. The confiscated items were submitted to the NBI for examination. Procedural History: The accused was charged with violating the Dangerous Drugs Act. After trial, the Court of First Instance of Manila found him guilty beyond reasonable doubt and sentenced him to life imprisonment, a P20,000.00 fine, and costs. The accused appealed this decision. The Petition: The accused appealed his conviction, claiming the prosecution failed to prove his guilt. Specifically, he argued that the alleged bag of marijuana turned over by the informant was not proven to be the same bag sold by him, and that the NBI forensic chemist was not qualified as an expert witness. He also questioned the admissibility of his alleged oral admission.
Issue(s)
Whether the prosecution sufficiently proved the identity and chain of custody of the confiscated marijuana. Whether the NBI forensic chemist was qualified as an expert witness. Whether the alleged oral admission of the accused was admissible and, if so, whether it was relied upon for conviction.
Ruling
The Supreme Court affirmed the decision of the lower court, finding the accused guilty beyond reasonable doubt of the crime charged. The penalty of life imprisonment and a fine of P20,000.00 were upheld.
Ratio Decidendi
On the issue of the identity and chain of custody of the confiscated marijuana: The Court held that the identity of the plastic bag was indubitable. Testimonies of the police officers established that the accused delivered a plastic bag to the informant in exchange for marked money, and that upon apprehension, the marked money and two more plastic bags of marijuana were recovered from the accused. The Court noted that the accused never questioned the identity of the plastic bag constituting the corpus delicti during the trial, thus estopping him from raising this issue on appeal. The Court also found that the presentation and identification of the plastic bags were not opposed by the defense, implying admission. On the qualification of the NBI forensic chemist as an expert witness: The Court found that the prosecution sufficiently established the competence of Miss Nieva Gamosa as a forensic chemist. She declared her position and duties, which included conducting biological chemical and physical analysis of dangerous drugs. The defense counsel did not object to the questions eliciting expert testimony and did not question her competence during cross-examination. The Court reiterated that scientific study is not always essential for expert competency, and practical experience can suffice. Furthermore, the witness demonstrated her expertise by correctly identifying marijuana and its constituents. On the admissibility and reliance on the alleged oral admission: The Court clarified that it had closely read the trial court's decision and found no instance where the court admitted or relied upon the alleged oral admission of the accused to find him guilty. The conviction was based solely on the credible testimonies of the prosecution witnesses, corroborated by the findings of the NBI Forensic Chemist. The trial court found the police officers' testimonies clear, straightforward, and trustworthy, and that the accused's mere denial could not prevail over the probative weight of their testimonies and the NBI findings.
Main Doctrine
The Court affirmed the conviction for illegal sale of marijuana, holding that the chain of custody of the confiscated marijuana was sufficiently established, the forensic chemist was competent to testify, and the alleged oral admission was not relied upon for conviction. The Court also emphasized that the accused's failure to question the identity of the confiscated bag during trial estopped him from raising the issue on appeal.
