Case Summary (G.R. No. 110357)

Charges and Accusatory Allegations

On 10 May 1991, an information was filed against the accused in Criminal Case No. 2574 before the RTC of Makati. The accusatory portion alleged that on or about 7 May 1991 in Makati, Metro Manila, the accused, “without the corresponding license, prescription or being authorized by law,” willfully sold, delivered, and distributed Methamphetamine Hydrochloride (shabu), a regulated drug, in violation of R.A. No. 6425.

Trial Evidence for the Prosecution: Buy-Bust Operation

After the accused pleaded not guilty on 25 October 1991, the prosecution presented witnesses consisting of Sgt. Jose Latumbo, SPO1 Francisco Matundan, Police Lt. Julita De Villa, and Teresita Alberto, and added SPO1 Francisco Matundan and SPO3 Albert San Jose in rebuttal.

The prosecution narrated that on 6 May 1991 at 11:00 p.m., a “confidential agent” or informer went to the office of NCRNU and reported to their superior, Capt. Jonathan Miano. The informer stated that a person known as “Jon-Jon,” later identified as the accused, was selling shabu along Kalayaan Avenue, Makati. Capt. Miano then organized a buy-bust team, naming himself as team leader and Sgt. Latumbo as the poseur-buyer, while the informer and other officers formed the support group.

Capt. Miano gave Sgt. Latumbo a P100 bill (Exhibit “B”) bearing serial number SN886097, dusted with fluorescent powder. The team used two cars to proceed to the target area. At the corner of Kalayaan Avenue and J.B. Roxas Street, the informer pointed out the accused standing in front of a house. Sgt. Latumbo and the informer approached the accused while the rest took vantage points.

The informer introduced Sgt. Latumbo as someone interested in buying shabu and asked if the accused had any for sale. The accused answered affirmatively and asked for the desired quantity. Sgt. Latumbo replied, “Pare, tapatan mo na lang itong piso ko,” indicating “piso” in illegal drug parlance meant one hundred pesos. The accused briefly left and entered his house. When he returned, he gave a package (Exhibit “F-2”) to Sgt. Latumbo, who then handed the accused the marked P100 bill. Sgt. Latumbo examined the package and, upon confirming it was shabu, gave the pre-arranged signal by scratching his head. Capt. Miano and the rest then closed in, identified themselves as NARCOM agents, and arrested the accused.

During interrogation, the accused voluntarily surrendered a plastic bag of shabu (Exhibit “F-3”) and the marked money (Exhibit “B”). The accused was handcuffed and taken to NARCOM headquarters.

Physical Identification and Forensic Chemistry

On 7 May 1991, SPO1 Matundan requested Teresita Alberto, Chief Chemist of the Physical Identification Division of the PNP Crime Laboratory Service, to examine both the accused’s person and the marked P100 bill. Alberto exposed the bill to ultraviolet radiation and found fluorescent powder on it. She likewise exposed the accused to ultraviolet radiation and found fluorescent powder on his hands, face, and on the opening of the left-side pocket of the white shorts he was wearing. The findings were recorded in Physical Identification Report No. PI-073-91 (Exhibit “C”).

Also on 7 May 1991, SPO1 Matundan delivered the specimens to Police Lt. Julita De Villa, a forensic chemist. These included Exhibit “F-2”, a 0.06-gram substance wrapped in aluminum foil, and Exhibit “F-3”, a 1.04-gram substance in a plastic bag. De Villa conducted three tests—chemical examination, thin-layer chromatography, and infrared spectrometric record analysis—and confirmed that both specimens were methamphetamine hydrochloride (shabu). The results were stated in Initial Chemistry Report No. D-464-91 (Exhibit “G”) and Final Chemistry Report No. D-464-91 (Exhibit “H”).

Defense: Denial and Alleged Framing

The accused denied the allegations and claimed that he was framed. He testified that on 6 May 1991 he stayed inside his house from morning until night with his parents, sisters (including his sister Clarita Cheng), a brother, nieces, a nephew, his wife, and a neighbor. At about 11:40 p.m., while he was fixing his videocassette recorder, he heard knocking at the front door. After his nephew opened the door, four men allegedly barged in and identified themselves as police officers Latumbo, Matundan, Tugade, and San Jose. He claimed that San Jose grabbed him by the collar and asked if he was “Jon-Jon,” and that they told him they needed money and that he should inform on drug sellers. He stated that no specific act of purchase or sale occurred and that Capt. Miano slapped him while a pistol was pointed at him. He claimed he was brought out and made to stand and talk, including a directive to point to a drug seller, which he said he refused.

He asserted that he was detained at Camp Crame and, later, that his hands and pocket were wiped with a P100 bill taken by Latumbo after his handcuffs were removed. He also claimed that he was made to undergo ultraviolet ray examination after returning to his cell.

Clarita Cheng testified to corroborate the accused’s account. She stated that she asked why the police were treating her brother that way and offered that if they did not believe him, they should kill him. She said that she sought to accompany her brother but was not allowed. She claimed that Matundan asked for gasoline and she gave P1,000.00, but that her brother was never returned.

On rebuttal, SPO3 San Jose and SPO1 Matundan denied that they barged into the accused’s house and illegally arrested him. Matundan denied receiving money from Clarita. San Jose denied wiping the P100 bill on the accused’s hands and pocket while he was detained.

RTC Conviction

On 23 March 1993, the trial court promulgated its decision convicting the accused. It sentenced him to life imprisonment and to pay a fine of P30,000.00. The RTC found the prosecution witnesses’ testimony credible and logical. It also invoked the rule that appellate courts generally do not disturb the trial court’s factual findings where issues hinge on witness credibility, absent a showing that the trial court overlooked material facts.

Issues on Appeal and the Supreme Court’s Appraisal of Credibility

On appeal, the accused argued that the constitutional presumption of innocence was not overcome by proof beyond reasonable doubt. The Court reviewed the trial court’s assessment of credibility. It held that the testimonies of the NARCOM agents enjoyed the presumption of regularity in the performance of official duty, and that the accused failed to prove any improper or ulterior motive.

The Court found the defense theory of framing unconvincing. It noted that the accused’s narrative—that police officers barged into a private dwelling in the middle of the night solely to force him to inform on drug sellers—was implausible, since officers could more easily pick a target when isolated. The Court also found it inconsistent to assert extortion, because the accused testified that no money was demanded from him in that context.

Regarding the fluorescent powder evidence, the Court held that the accused’s claim that the marked money was wiped on his hands and pocket was unsupported except by his bare allegation. The Court emphasized that a frame-up allegation must be proven by clear and convincing evidence, because the presumption of regularity requires strong proof of fabrication.

Challenges to the Buy-Bust Procedure

The accused contended that there was no prior surveillance and argued that this created doubt as to regularity of the entrapment. The Court rejected the contention, stating that prior surveillance was not a prerequisite for a valid entrapment operation. It also stated that there is no rigid method of conducting buy-bust operations and that police work requires flexibility.

The accused further argued that there was no mission order and that no investigation report was made after the operation. The Court held that a mission order is not an essential requisite for a valid buy-bust and that while an investigation report was not shown to have been executed, the prosecution evidence included testimony that SPO3 San Jose prepared the booking sheet, receipt of seized property, and the affidavit of arrest.

The defense objected to the non-presentation of the informer. The Court found no merit. It held that the informer’s testimony would have been merely corroborative since the poseur-buyer and other witnesses already established how the crime was committed. The identity or testimony of the informer may be dispensed with when the narration is cumulative to that of the person who directly witnessed the sale.

Constitutional Claim: Self-Incrimination and Counsel During Ultraviolet Examination

The accused argued that his right against self-incrimination was violated when he was subjected to ultraviolet ray examination. He also argued that the Chief Chemist failed to inform him of his right to counsel before the examination.

The Court rejected these contentions. It held that the constitutional guarantee against self-incrimination prohibits the use of physical or moral compulsion to extort communication. It is not violated by the inclusion of the body in evidence when the physical examination is material. The Court further ruled that subjecting the accused’s body to ultraviolet radiation for detection of ultraviolet powder was not a custodial investigation requiring the presence of counsel.

Accordingly, the Court affirmed the trial court’s finding that the accused was caught in flagrante selling shabu to the buy-bust team.

Modification of Penalty Under R.A. No. 7659 and the Quantity-Based Rule

Although the Court affirmed conviction, it modified the penalty due to amendments introduced by R.A. No. 7659 to R.A. No. 6425, which took effect on 31 December 1993. The amendments changed the penalty framework so that, in general, the penalty under Section 15 became dependent on the quantity of the regulated drug involved, and the
