People vs. Diputado

In prosecutions for illegal sale of dangerous drugs, the prosecution must establish an unbroken chain of custody from seizure to presentation in court; failure to mark the seized item immediately after seizure, unexplained additional markings on the specimen, and non-presentation of a key custodial witness create reasonable doubt as to the integrity and evidentiary value of the corpus delicti, warranting acquittal.

Rommel Diputado was charged with illegal sale of methamphetamine hydrochloride (shabu) under Section 5, Article II of Republic Act No. 9165, the "Comprehensive Dangerous Drugs Act of 2002," following a buy-bust operation conducted by the Regional Special Anti-Crime Task Force (RSAC-TF) of the Philippine National Police, Region 6. The operation arose from information provided by a police asset that Diputado, already on the Task Force's Watch List, was engaged in selling drugs in Brgy. San Vicente, Jaro, Iloilo City. A prior test-buy operation had been conducted on March 3, 2006, after which a formal buy-bust was planned and executed on March 7, 2006.

On February 27, 2006, a police asset informed P/Sr. Insp. Gallardo of the Regional Special Anti-Crime Task Force (RSAC-TF) that a certain Rommel Diputado, already on the Task Force's Watch List, was engaged in selling drugs in Brgy. San Vicente, Jaro, Iloilo City. Gallardo instructed PO1 Ronald Estares and PO1 Ygan to conduct surveillance and a test-buy operation. On March 3, 2006, they purchased suspected shabu worth ₱500 from Diputado in Brgy. San Jose, Molo, Iloilo City. Gallardo then directed a formal buy-bust operation.

On the morning of March 7, 2006, Gallardo conducted a briefing in which PO1 Estares was designated poseur-buyer and PO1 Lord Ambrocio as his buddy. Estares was given buy-bust money amounting to ₱24,000, consisting of five twenty-peso bills, four of which were authenticated at the Iloilo City Prosecution Office, and the remainder in fake money of various denominations. The operation was set for approximately 1:00 p.m. at Brgy. San Vicente, Jaro, with Gallardo's group serving as back-up. At around 10:00 a.m., Estares and Ambrocio positioned themselves at a billiard hall and eatery in the target area. After about an hour and a half, the asset arrived and told them to wait for the accused.

According to the prosecution, at about 12:45 p.m., Diputado arrived and Estares transacted with him at a street corner for the purchase of shabu worth ₱24,000. Diputado told them to wait, left the area, and returned after a while alighting from a taxi. He approached Estares and Ambrocio and asked for the money. Estares handed over the buy-bust money, which Diputado placed in his pocket, and Diputado in turn handed Estares a big sachet containing a white crystalline substance. At that point, Estares and Ambrocio identified themselves as police officers, frisked the accused, and recovered the buy-bust money. Ambrocio called the back-up team, which arrived and brought the accused, together with the seized item, to the house of the barangay captain approximately 100 meters away.

At the barangay captain's house, PO2 Lucilo Mayores recorded the seized item and buy-bust money in a document signed by barangay kagawads and a media representative. Estares then brought the items to the RSAC-TF office, where he marked the plastic sachet with "RDM," the initials of the accused, and turned the listed items over to PO1 Alfredo Tilano, the Exhibit Custodian. Thereafter, the items were brought to the Iloilo City Prosecution Office for inventory before Prosecutor Elvas, in the presence of a barangay kagawad and a media representative, who signed the inventory document. The sachet was then submitted to the PNP Crime Laboratory for examination.

For his part, Diputado testified that at around 1:00 p.m. on March 7, 2006, after lunch at his home in Brgy. North San Jose, Molo, he rode a taxi to Brgy. Tabuc-Suba, Jaro, having been asked by a friend to help butcher a pig. While passing through Brgy. San Vicente, Jaro, the taxi was blocked by three persons, one of whom greeted him and brought him to the back of the taxi. He was then taken to the house of the Barangay Captain of Brgy. San Vicente, about 100 meters away. There, he was surprised when the three persons presented money and shabu to the Barangay Captain and directed him to point at the items. He initially refused but eventually pointed at them, at which point he was photographed with a cellphone. He was then brought to the Hall of Justice.

The RTC credited the prosecution's version and convicted Diputado of illegal sale of dangerous drugs, imposing life imprisonment and a fine of ₱500,000. The CA affirmed the conviction in toto. On appeal to the Supreme Court, the defense focused not on the buy-bust operation's occurrence but on the integrity of the seized item, pointing to multiple gaps in the chain of custody that cast doubt on whether the substance presented in court was the same one allegedly recovered from the accused.

• Delayed Marking of Seized Item: Accused-appellant argued that the seized illegal drug was not marked immediately after his arrest at the scene, nor at the barangay captain's house where the seized items were initially recorded; it was only marked at the RSAC-TF office, creating a gap in the chain of custody.
• No Photographs During Inventory: Accused-appellant contended that there was no evidence on record that photographs were taken during the inventory of the seized items, as required by Section 21 of R.A. No. 9165.
• Non-Presentation of PO3 Holleza: Accused-appellant argued that the prosecution's failure to present PO3 Allen Holleza, the person who allegedly received the Request for Laboratory Examination, was fatal to the case, especially given the unexplained additional marking "RGE" on the plastic sachet.
• Unexplained Additional Marking "RGE": Accused-appellant pointed out that the marking "RGE" appeared on the sachet but was not mentioned in any prosecution document nor explained by any witness, creating doubt as to who handled the seized item and whether it had been tampered with.
• Procedural Lapses Creating Reasonable Doubt: Accused-appellant maintained that the cumulative procedural lapses and gaps in the chain of custody, coupled with the police officers' failure to offer justifiable reasons for non-compliance with Section 21 of R.A. No. 9165, created reasonable doubt as to the integrity and evidentiary value of the seized illegal drug.

• Sufficiency of Evidence: Whether the trial court and the Court of Appeals erred in finding that the prosecution's evidence was sufficient to convict the accused of the alleged sale of methamphetamine hydrochloride in violation of Section 5 of R.A. No. 9165.
• Chain of Custody: Whether the prosecution established an unbroken chain of custody over the seized dangerous drug, preserving its integrity and evidentiary value from the time of seizure to presentation in court.

• Sufficiency of Evidence: No. The prosecution failed to prove the accused's guilt beyond reasonable doubt because the integrity and evidentiary value of the seized dangerous drug were not preserved, the chain of custody having been broken at multiple points.
• Chain of Custody: No. The seized item was not marked immediately after seizure, an unexplained additional marking "RGE" appeared on the sachet, and the prosecution failed to present PO3 Holleza, the witness who could have explained the additional marking, all of which compromised the identity and integrity of the corpus delicti.

• Sufficiency of Evidence: In a prosecution for illegal sale of dangerous drugs, the prosecution must establish the identity of the buyer and seller, the object, and the consideration, plus the delivery of the thing sold and payment therefor. Critically, the corpus delicti—the dangerous drug itself—must be independently established beyond reasonable doubt, and the identity of the drug must be established with the same unwavering exactitude as that required for a finding of guilt. The unique characteristic of dangerous drugs—being indistinct, not readily identifiable, and easily open to tampering, alteration, or substitution—necessitates that the prosecution definitively show the illegal drug presented in court is the same one recovered from the accused. Because the chain of custody was broken, the prosecution could not meet this standard, and the presumption of innocence prevailed.

• Chain of Custody: Section 21 of R.A. No. 9165 and its Implementing Rules and Regulations require that the apprehending team physically inventory and photograph seized items immediately after seizure in the presence of the accused, a media representative, a DOJ representative, and an elected public official. The IRR provides a saving clause: non-compliance is excused under justifiable grounds provided the integrity and evidentiary value of the seized items are properly preserved. Marking is the starting point in the custodial link, separating the seized evidence from the corpus of all other similar evidence and preventing switching, planting, or contamination. Here, PO1 Estares did not mark the seized item at the place of arrest or at the barangay captain's house; it was marked only at the RSAC-TF office, and there was no testimony that the marking was done in the accused's presence or any justification offered for the delay. The Receipt of Confiscated or Seized Articles and the Complaint-Affidavit did not mention any markings. The Inventory of Confiscated or Seized Articles likewise did not show markings, and "RDM" only appeared in the Request for Laboratory Examination, casting doubt on when marking actually occurred. The additional marking "RGE" appeared on the sachet but was not mentioned in any document or explained by any witness. PO3 Holleza, who allegedly received the Request for Laboratory Examination, was not presented and could have shed light on the additional marking. These unexplained gaps meant the prosecution failed to ensure the seized item was the same one marked, examined, and presented in court. The presumption of regularity in the performance of official duties could not save the prosecution's case, as it stands only when no reason exists to doubt the regularity of official performance, and it can never override the presumption of innocence in favor of the accused.

• Chain of Custody in Drug Cases — The duly recorded authorized movements and custody of seized drugs from the time of seizure/confiscation to receipt in the forensic laboratory, to safekeeping, and to presentation in court for identification and destruction. The record must include the identity and signature of the person who held temporary custody, the date and time of transfer, and the final disposition. The Court applied this doctrine to find that the prosecution failed to establish an unbroken chain, as the seized item was not marked immediately after seizure, an unexplained additional marking appeared, and a key custodial witness was not presented.

• Marking as the Starting Point of the Custodial Link — Marking is the placing by the apprehending officer or poseur-buyer of his/her initials and signature on the items seized, immediately after seizure. It separates the marked evidence from all other similar or related evidence, preventing switching, planting, or contamination. The Court found that the failure to mark the seized item immediately at the place of arrest or at the barangay captain's house, without any justification, compromised the integrity of the evidence from the very first step of the chain.

• Presumption of Regularity vs. Presumption of Innocence — The presumption of regularity in the performance of official duties stands only when no reason exists in the records to doubt the regularity of official performance. Even when it applies, the presumption of regularity will never be stronger than the presumption of innocence in favor of the accused; otherwise, a mere rule of evidence would defeat the constitutionally enshrined right of an accused. The Court held that the documented lapses in chain of custody negated the presumption of regularity, and the prosecution's failure to overcome the presumption of innocence required acquittal.

• Saving Clause Under Section 21(a), IRR of R.A. No. 9165 — Non-compliance with the inventory and photography requirements of Section 21 is excused under justifiable grounds, provided the integrity and evidentiary value of the seized items are properly preserved by the apprehending officer/team. The Court noted that the prosecution offered no justifiable reason for the failure to mark the seized item immediately, and the integrity and evidentiary value were not preserved due to the unexplained gaps in custody.

• "The duty of the prosecution is not merely to present in evidence the seized illegal drugs. It is essential that the illegal drugs seized from the suspect is the very same substance offered in evidence in court as the identity of the drug must be established with the same unwavering exactitude as that required to make a finding of guilt." — This passage articulates the exacting standard the prosecution must meet in drug cases regarding the identity and integrity of the corpus delicti, and is frequently cited in subsequent drug-case jurisprudence.

• "The presumption of regularity in the performance of official duties in favor of the police officers will not save the prosecution's case, given the foregoing lapses and gaps in the chain of custody. The presumption stands only when no reason exists in the records by which to doubt the regularity of the performance of official duty. And even in that instance, the presumption of regularity will never be stronger than the presumption of innocence in favor of the accused." — This passage defines the hierarchy between the presumption of regularity and the constitutional presumption of innocence, explaining why procedural lapses in drug cases can defeat an otherwise valid arrest.

• "Marking after seizure is the starting point in the custodial link. It is vital that the seized contraband be immediately marked because succeeding handlers of the specimens will use the markings as reference." — This passage defines the doctrinal significance of immediate marking in the chain of custody, establishing it as the foundational step that all subsequent custodial transfers depend upon.

• Section 5, Article II, Republic Act No. 9165 — Defines and penalizes the sale, trading, administration, dispensation, delivery, distribution, and transportation of dangerous drugs. The accused was charged under this provision for selling 3.957 grams of methamphetamine hydrochloride for ₱24,000. The penalty imposed by the RTC was life imprisonment and a fine of ₱500,000.
• Section 21, Article II, Republic Act No. 9165 — Prescribes the procedure for custody and disposition of confiscated, seized, and/or surrendered dangerous drugs, requiring immediate physical inventory and photograph of seized items in the presence of the accused, a media representative, a DOJ representative, and an elected public official, and submission to the forensic laboratory within 24 hours. The Court found that the apprehending officers failed to comply with these requirements, creating gaps in the chain of custody.
• Section 21(a), Article II, Implementing Rules and Regulations of R.A. No. 9165 — Elaborates on Section 21, providing that the physical inventory and photograph may be conducted at the place of seizure or at the nearest police station or office of the apprehending team, and containing the saving clause that non-compliance shall not render seizures void provided justifiable grounds exist and the integrity and evidentiary value of the seized items are properly preserved. The Court found no justifiable ground was offered for the non-compliance.

Velasco, Jr. (Chairperson), Bersamin, Reyes, and Leonen concurred. No separate concurring opinions were noted.
