Protecting Rights Illegal Drug Possession AND THE Chain OF Custody Rule

The Supreme Court, in Padas y Garcia v. People (G.R. No. 244327, October 14, 2019), acquitted Rowena Padas of illegal possession of dangerous drugs. The ruling is a clear reminder that in drug cases, the prosecution must do more than prove possession—it must also prove, with moral certainty, that the drugs presented in court are the same ones seized from the accused. When police fail to follow the chain of custody rule under Section 21 of Republic Act No. 9165, the case can collapse, even if the accused was caught with prohibited drugs.

The Facts of the Case

On July 20, 2013, two police officers were conducting surveillance in Sampaloc, Manila, looking for a person known as "Manok." After about an hour without seeing their target, they decided to leave. As they were about to depart, they allegedly saw a woman—later identified as Padas—take a plastic sachet from her pocket and show it to an unidentified man. The officers arrested her and found three sachets containing a total of 0.08 gram of methamphetamine hydrochloride, or shabu.

The officers marked the sachets "RGP," "RGP-1," and "RGP-2." They conducted the physical inventory and took photographs at the place of arrest. However, the only witness present was a media representative, Rene Crisostomo. No representative from the Department of Justice (DOJ) and no elected public official witnessed the inventory. The media representative himself was not present during the arrest or the marking of the evidence—he only signed the inventory afterward.

The Issue Before the Court

The central issue was whether the prosecution had proven Padas's guilt beyond reasonable doubt, particularly whether the chain of custody of the seized drugs was properly established. Padas also raised the legality of her warrantless arrest, but the Court noted that she had waived this objection by failing to question it before her arraignment.

The Chain of Custody Rule

The chain of custody rule is designed to safeguard the identity and integrity of seized drugs. It requires the apprehending team to physically inventory and photograph the seized items immediately after confiscation, in the presence of:

• The accused or the person from whom the items were seized, or their representative or counsel
• A representative from the media
• A representative from the DOJ
• An elected public official

All four witnesses must sign the inventory and receive a copy. The law recognizes that drugs are indistinct, not readily identifiable, and easily tampered with, altered, or substituted. The presence of these witnesses protects the accused from planted or substituted evidence.

Why the Conviction Was Reversed

The prosecution admitted that no DOJ representative and no elected public official were present during the inventory. Worse, the media representative did not actually witness the marking of the evidence—he merely signed the inventory form afterward.

The law has a saving clause that allows non-compliance if the prosecution can show justifiable grounds and prove that the integrity of the evidence was preserved. But in this case, the prosecution offered no justification at all for the missing witnesses. It did not even acknowledge the procedural lapses.

The Court ruled that the signature of the media representative was "rendered useless" because he did not witness the actual inventory and marking. The Court emphasized that police officers must not merely call witnesses to sign documents after the fact—the witnesses must be present during the actual inventory to prevent the planting of drugs.

Because the prosecution failed to prove that the integrity and evidentiary value of the seized drugs were preserved, serious doubt hung over the identity of the corpus delicti. The Court reversed the conviction and acquitted Padas.

Practical Takeaways

• Strict compliance matters. In drug cases, police must follow Section 21 of RA 9165 to the letter. The presence of all required witnesses—media, DOJ, and an elected official—is mandatory, not optional.

• The saving clause has limits. Non-compliance can be excused only if the prosecution explains the justifiable grounds and proves the drugs were not tampered with. Silence on the lapses is fatal.

• Witnesses must actually witness. Having a witness sign an inventory after the fact does not cure the defect. The witness must be present during the actual inventory, marking, and photographing of the evidence.

• The presumption of regularity is lost. When police fail to comply with Section 21, the prosecution cannot rely on the presumption of regularity in the performance of official duties. It must independently prove the integrity of the evidence.

• Object to illegal arrest early. An accused who fails to question the legality of a warrantless arrest before arraignment waives that objection. The defense should raise it at the earliest opportunity.
