Chain of Custody Integrity Key to Successful Drug Possession Cases in the Philippines

The Supreme Court has reaffirmed that strict compliance with the chain of custody rule is a matter of substantive law, not mere procedure, in drug possession cases. In Saban v. People (G.R. No. 253812, June 28, 2021), the Court acquitted a visitor to the Manila City Jail after law enforcers failed to secure the required witnesses during the inventory and photography of seized drugs. The ruling serves as a critical reminder that the prosecution must prove the integrity of the seized item — the corpus delicti — with moral certainty, or the accused walks free.

The Facts of the Case

On December 17, 2014, Jail Officer Linda Lominio was conducting a body search on Noila Saban, who arrived to visit her incarcerated husband. The officer noticed a bulge in Saban's cheek and asked her to spit out whatever she was chewing. Saban eventually complied and spat out a folded brown packaging tape containing two plastic sachets of white crystalline substance later confirmed to be methamphetamine hydrochloride, or shabu.

The searchers marked the sachets, prepared an inventory, and photographed them. They attempted to call a barangay official but none came. No representative from the National Prosecution Service (NPS) or the media was ever contacted. The seized items were later tested and found positive for shabu. Saban was charged with illegal possession of dangerous drugs under Section 11(3), Article II of Republic Act No. 9165.

The Issue Before the Court

The central question was whether the prosecution had adequately preserved the integrity and evidentiary value of the seized drugs despite the apprehending officers' failure to comply with the witness requirements under Section 21, Article II of RA 9165, as amended by RA 10640.

The Ruling

The Supreme Court ruled in favor of Saban and ordered her acquittal. The Court emphasized that in drug possession cases, the dangerous drug itself forms an integral part of the corpus delicti. The prosecution must account for each link of the chain of custody — from seizure to presentation in court — to establish the drug's identity with moral certainty.

Because the seizure occurred after RA 10640 took effect on August 7, 2014, the applicable rule required the presence of (a) an elected public official and (b) a representative of the NPS or the media during the physical inventory and photography of the seized items.

In this case, none of these witnesses were present. While the officers claimed they tried to secure a barangay official, they admitted making no attempt whatsoever to contact an NPS representative or a member of the media. The Court found this to be a complete and unjustified non-compliance with the chain of custody rule.

The Court stressed that mere statements of unavailability are unacceptable. The prosecution must show genuine and sufficient efforts to secure the required witnesses. Without such justification, the integrity and evidentiary value of the seized items are deemed compromised.

Practical Takeaways

• Witness presence is mandatory. After RA 10640, the required witnesses during inventory and photography are an elected public official and a representative of the NPS or media. Their absence must be justified by genuine efforts to secure their presence.

• Document all attempts. Law enforcers should keep a record of their efforts to contact required witnesses, including the names of those contacted and the reasons for non-appearance. Vague claims of unavailability will not suffice.

• Chain of custody is substantive law. Non-compliance is not a mere technicality. The prosecution bears the burden of proving that the integrity of the seized drugs was preserved despite any deviation from the prescribed procedure.

• For the accused, challenge procedural lapses. A conviction may be reversed on appeal if the prosecution fails to account for missing witnesses or unexplained gaps in the chain of custody.

• For practitioners, scrutinize the records. Defense counsel should examine whether the prosecution presented justifiable reasons for any non-compliance with Section 21, as this can be the decisive factor between conviction and acquittal.
