Chains Unbroken Safeguarding Rights In Drug Cases Through Strict Evidence Procedures

The Supreme Court acquits a drug suspect because police failed to secure required witnesses during inventory, reinforcing strict chain-of-custody rules.


The Supreme Court has once again emphasized that in drug cases, the procedure for handling seized evidence is just as important as the evidence itself. In People v. Maganon (G.R. No. 234040, June 26, 2019), the Court acquitted an accused because the police failed to secure the required witnesses during the inventory of seized drugs. The ruling serves as a firm reminder that law enforcers cannot take shortcuts when preserving the chain of custody.

The Case: A Buy-Bust Operation in Pasig City

On November 23, 2014, police operatives in Pasig City conducted a buy-bust operation against Augusto Maganon. PO1 Marvin Santos acted as the poseur-buyer and purchased two sachets of suspected shabu from Maganon for two hundred pesos. After the arrest, police recovered four more sachets from Maganon's possession.

The following day, the police conducted an inventory of the seized items at the barangay hall. Only Barangay Captain Engracio Santiago was present during the inventory. No representative from the media or the Department of Justice (DOJ) attended, despite the requirements of Section 21 of Republic Act No. 9165, as amended by RA 10640.

The Regional Trial Court convicted Maganon of illegal sale and illegal possession of dangerous drugs. The Court of Appeals affirmed the conviction. Maganon appealed to the Supreme Court, arguing that the police violated the chain-of-custody rules.

The Issue: Did the Police Comply with Section 21?

The central question was whether the police properly complied with Section 21, Article II of RA 9165, which requires that the physical inventory and photographing of seized drugs be conducted in the presence of the accused, an elected public official, and a representative of the National Prosecution Service or the media.

The prosecution admitted that no media or DOJ representative was present. PO1 Santos explained that his media contact had changed numbers, and his chief allegedly tried to call a DOJ representative but none was available.

The Ruling: Earnest Efforts Are Required

The Supreme Court found these explanations insufficient and acquitted Maganon. The Court emphasized that the prosecution must prove two things for the saving clause to apply: (1) justifiable grounds for non-compliance, and (2) that the integrity and evidentiary value of the seized items were properly preserved.

The Court noted that the police had ample time to secure the required witnesses. The decision to conduct the buy-bust operation was made a day before it actually happened. PO1 Santos did not explain why he failed to find another media representative during that time.

The Court also pointed out a critical detail: it was Barangay Captain Santiago himself who requested the buy-bust operation against Maganon. Having him as the sole witness during the inventory defeated the purpose of the law, which is to provide an "insulating presence" that prevents switching, planting, or contamination of evidence.

The Importance of an Unbroken Chain of Custody

The Court reiterated that the identity of the dangerous drugs is the very corpus delicti of the crime. Every link in the chain of custody must be accounted for, from the moment of seizure to presentation in court. Mere statements of unavailability, without showing actual serious attempts to contact the required witnesses, are unacceptable.

Practical Takeaways

  • Police must exert earnest efforts to secure witnesses. A mere claim that a media contact changed numbers or that a DOJ representative was unavailable is not enough. The prosecution must prove actual attempts were made.
  • The saving clause is not automatic. Non-compliance with Section 21 does not automatically invalidate the seizure, but the prosecution must acknowledge the lapse and provide justifiable reasons, proven as fact.
  • Ample time matters. If police had time to plan the operation, they had time to arrange for the required witnesses. Courts will scrutinize unexplained delays.
  • The witness must be truly independent. If the sole witness is personally interested in the case, such as a barangay captain who requested the operation, the insulating purpose of the law is defeated.
  • For the accused, procedural lapses can mean acquittal. A conviction for drug offenses requires proof beyond reasonable doubt, which includes strict compliance with the chain-of-custody rules.
