Case Summary (G.R. No. 141244)

Factual Background

On May 7, 1998, at about 5:30 a.m., Intel-Agent Aide Noel Lucas and Intel-Agent Aide Amelia Palacay of the Department of the Interior and Local Government’s National Action Committee on Anti-Hijacking and Terrorism (NACAHT) were assigned to the 2nd Regional Aviation and Security Group. Palacay operated the x-ray machine, while Lucas worked as a baggage inspector.

A red and white plastic bag passed through the x-ray machine. The x-ray monitor showed that the bag contained a black box, which in turn contained a green kerosene stove. Palacay testified that the contents of the kerosene stove appeared blurred on the x-ray screen and could not be identified. She asked Lucas to open the plastic bag and check its contents.

Lucas asked who owned the plastic bag. Accused-appellant answered, “Sa akin `yan” (“That’s mine”). At the time, accused-appellant stood beside the x-ray machine immediately after the metal detector. Lucas then asked accused-appellant to open the bag for inspection, but accused-appellant refused. Lucas reported the refusal to SPO3 Dan Fabiana, the supervisor present at the check-in inspection area.

Fabiana and accused-appellant conferred. Fabiana testified that accused-appellant asked him, “Sir, paki tulungan naman ako na huwag ng buksan ang baggage ko” (“Sir, please help me so that my baggage would not have to be opened”). When Fabiana asked why accused-appellant did not want the baggage opened, accused-appellant allegedly replied that it contained money. Fabiana then asked whether accused-appellant had stolen the money and was refusing to open the bag. Fabiana directed accused-appellant to point to where his baggage was. Accused-appellant complied and pointed to the bag.

Fabiana then ordered Lucas to open the plastic bag placed on top of the inspection table. Before the bag was opened, accused-appellant allegedly told Fabiana that he owned it. Lucas actually inspected the plastic bag in the presence of Police Chief Inspector Moises Tuliao and Senior Inspector Mateo of the PNP Aviation Security Group.

Upon opening, Lucas found a box containing the green kerosene gas stove. Lucas unscrewed the stopper of the stove’s gas tank and found a black plastic bag containing twenty (20) plastic sachets with a white crystalline substance. Fabiana wrote his initials on the plastic bag, and both Fabiana and Lucas placed their initials on each of the twenty sachets to prevent substitution and to show that the items came from accused-appellant. Fabiana then placed accused-appellant under arrest and turned him over to Inspector Tuliao for investigation. The sachets were sent to the PNP Crime Laboratory for examination. Each sachet weighed a little over 49 grams, and the total weight was 984.58 grams. After a qualitative examination, P/INSP Efren E. Fadriquela, the forensic chemist, found that the substance in each sachet was positive for methamphetamine hydrochloride (shabu). He submitted both an initial laboratory report and a final laboratory report.

Defense Evidence and Theory

Accused-appellant denied ownership and participation in the possession of the shabu. He claimed that in the early morning of May 7, 1998, he arrived at the Pasay City Domestic Airport with his cousin Alvin Muhammad and that he was traveling to Cotabato to attend the death anniversary of his grandfather. Accused-appellant testified that when he entered Terminal 1, he carried a black bag containing a prayer book, a rosary, and a radio cassette. He asserted that the black bag was what he placed on the conveyor belt going through the x-ray machine.

Accused-appellant alleged that Lucas accosted him, asked to see his ticket, and read his name written on it. He testified that Lucas then required him to open a red and white plastic bag on top of the x-ray inspection table. Accused-appellant claimed that he refused because it was not his. When he was about to leave, accused-appellant asserted that Fabiana arrived and Lucas informed Fabiana that accused-appellant refused to open the bag. Accused-appellant then alleged that Fabiana drew his gun and poked it at him. When he again refused to open the plastic bag, he was allegedly handcuffed and taken to an office for investigation.

Accused-appellant claimed that the plastic bag was taken to the office by Lucas. He said he was shown the shabu that had allegedly been recovered from the plastic bag, and some sachets were placed in his hands. Accused-appellant testified that he threw them away. He further alleged that Lucas, with a gun drawn, demanded P1 million, but he told them he had no money. Accused-appellant also testified that he was detained in a small cell and that the next morning Fabiana apologized, stating that the occurrence was an accident and that it was not accused-appellant’s.

His cousin, Alvin Mohammad, testified consistently with accused-appellant’s denials, but the defense evidence largely consisted of negative assertions.

Issues Raised on Appeal

Accused-appellant assigned as error the trial court’s reliance on (1) the alleged admission of ownership over the red and white plastic bag that allegedly yielded the kerosene stove containing shabu, and (2) a presumed regularity in the arresting officers’ performance of duty. He insisted he neither made the statement “Sa akin `yan” nor asked the officers not to open the baggage. He also argued that the prosecution evidence contained enough doubts to overturn the conviction.

Resolution by the Court: Credibility and Factual Findings

The Court rejected accused-appellant’s contentions and sustained the RTC’s appreciation of evidence. It held that accused-appellant’s denial could not prevail over the prosecution witnesses’ affirmative and categorical testimony. The Court stressed that denials unsubstantiated by clear and convincing evidence constituted negative self-serving evidence, which carried no weight compared with positive declarations of credible witnesses. It pointed out that the prosecution witnesses testified that accused-appellant admitted that the red and white plastic bag belonged to him, asked for help so that the bag would not be opened, and that the inspection revealed a kerosene stove containing a black plastic bag with twenty sachets holding a white crystalline substance later identified as shabu. The defense offered no clear and convincing evidence to support the denials.

On accused-appellant’s claim of frame-up, the Court treated the defense as requiring strong and convincing evidence, considering the presumption that law enforcement agents acted in the regular performance of their official duties. It found that accused-appellant failed to rebut this presumption. Aside from the general allegation that he refused to pay P1 million, he did not present evidence of improper motive on the part of the officers. The Court considered frame-up in drug cases as a defense that could be easily invoked and therefore required substantial support.

The Court also emphasized that the case involved credibility determinations and factual issues, which fell within the trial court’s domain because it had the opportunity to observe the witnesses’ deportment and manner of testifying. It upheld the RTC’s findings for lack of any clear showing that the trial court overlooked or misapplied facts or circumstances of weight.

Alleged Inconsistencies in Testimony

Accused-appellant also argued that inconsistencies among prosecution witnesses undermined their credibility. The Court addressed purported discrepancies involving such matters as whether one or two x-ray machines were used; whether there were m

Parties and Procedural Posture

The People of the Philippines appealed from the Regional Trial Court, Branch 116, Pasay City, which convicted accused-appellant Salipada Mustapa y Muhammad.
The RTC decision dated November 11, 1999 found the accused guilty of violating Section 16 of R.A. No. 6425, as amended by R.A. No. 7659.
The RTC imposed reclusion perpetua, ordered the payment of a fine of P500,000.00, and directed the turn-over of the seized drugs for disposition in accordance with law.
The accused-appellant elevated the case to the Supreme Court, assigning errors that challenged both the evidentiary basis for conviction and the credibility of the prosecution witnesses.

The second issue raised whether the RTC erred in convicting the accused despite asserted doubt as to culpability.
The subsidiary issues effectively questioned (a) the credibility
