Acquittal in Drug Cases: The High Cost of Broken Chain of Custody

In a significant ruling, the Supreme Court acquitted Sonia Bernel Nuarin of illegal sale of drugs, emphasizing that the prosecution's failure to prove the chain of custody of seized shabu is fatal to a conviction. The case underscores a crucial principle in Philippine criminal law: the presumption of innocence cannot be overcome by evidence that raises serious doubts about the integrity of the seized items.

The Case Background

On February 2, 2003, police officers conducted a buy-bust operation against Nuarin in Quezon City. PO1 Roberto Manalo, acting as poseur-buyer, allegedly purchased P100.00 worth of shabu from the appellant. After the transaction, other officers searched Nuarin and found two additional plastic sachets in her coin purse.

The Regional Trial Court (RTC) convicted Nuarin of illegal sale of drugs under Section 5, Article II of Republic Act No. 9165 (Comprehensive Dangerous Drugs Act of 2002), sentencing her to life imprisonment and a P500,000.00 fine. The Court of Appeals affirmed the conviction. Nuarin appealed to the Supreme Court, arguing that the prosecution failed to establish that a buy-bust operation took place and that the chain of custody over the seized shabu had been broken.

The Issue

The central issue was whether the prosecution proved Nuarin's guilt beyond reasonable doubt, particularly whether it established the identity and integrity of the corpus delicti—the seized shabu—through an unbroken chain of custody.

The Ruling: Acquittal

The Supreme Court reversed the conviction and acquitted Nuarin. The Court held that while the prosecution established the elements of illegal sale—the identities of the buyer and seller, the transaction, and the existence of the drug—it failed to prove the chain of custody required under the law.

The Marking Requirement

The Court emphasized that marking the seized drugs immediately after seizure is the starting point of the custodial link. Under the rules, marking should be done in the presence of the apprehended violator immediately upon confiscation. This protects innocent persons from fabricated searches and protects officers from allegations of planting evidence.

In this case, PO1 Manalo gave conflicting statements. In his direct testimony, he claimed the desk officer marked the sachets. Later, he said he marked them himself. The records also did not show that the sachets were marked in Nuarin's presence. The Joint Affidavit of Arrest did not even mention marking.

Gaps in the Custodial Link

The Court noted several other gaps. The identity of the desk officer who received the seized items was never revealed. PO1 Manalo could not remember who brought the specimens to the crime laboratory. The specimen was forwarded only at 10:35 p.m., leaving unclear who had custody in the interim.

The stipulation on the forensic chemist's testimony did not help. The RTC itself noted that the chemist had no personal knowledge of from whom the specimen was taken.

Non-Compliance with Section 21

Section 21, Article II of R.A. No. 9165 requires the apprehending team to physically inventory and photograph the seized drugs immediately after seizure, in the presence of the accused or her representative, a media representative, a DOJ representative, and an elected public official.

PO1 Manalo admitted that the police did not make an inventory or photograph the seized items. No acceptable reason was offered for this failure, even though only three sachets were involved.

No Presumption of Regularity

The Court rejected the lower courts' reliance on the presumption of regularity in the performance of official duties. Given the procedural lapses and the allegations of frame-up and extortion, the presumption was negated. The Court also noted the absence of a pre-operation report or coordination with the PDEA and barangay officials, casting doubt on the legitimacy of the buy-bust operation.

Practical Takeaways

• Chain of custody is a strict requirement. The prosecution must prove that the drugs presented in court are the same drugs seized from the accused. Any break in the link can be fatal.

• Marking must be immediate and witnessed. Seized items should be marked in the presence of the accused, immediately upon confiscation or at the nearest police station.

• Document everything. Police should prepare pre-operation reports, coordination sheets, and joint affidavits that detail the handling of seized items.

• Comply with Section 21. Physical inventory and photographing in the presence of required witnesses are mandatory. Non-compliance may be excused only with justifiable grounds and proof that the evidence's integrity was preserved.

• Presumption of regularity is not automatic. Procedural lapses can negate the presumption of regularity in police officers' performance of duties.
