Reasonable Doubt When Buy-Bust Operations Fail to Prove Guilt in Drug Cases

In drug cases, the prosecution must prove guilt beyond reasonable doubt. When police fail to follow the chain of custody rule, the integrity of the seized drugs is compromised—and the accused may be acquitted. The Supreme Court's ruling in People v. De Motor y Dantes (G.R. No. 245486, November 27, 2019) shows how a missing witness during inventory can break the prosecution's case.

The Facts of the Case

In August 2012, Lipa City police conducted a buy-bust operation against Ronald Jaime De Motor y Dantes at a Jollibee branch. Officers recovered five sachets of dried marijuana leaves from him, then found four more during a frisking. The police marked all nine sachets and brought the accused to their headquarters, where they conducted an inventory and photography in the presence of the accused, a barangay captain, and a radio station member. Notably, no Department of Justice (DOJ) representative was present.

The Regional Trial Court convicted De Motor of illegal sale and illegal possession of dangerous drugs under Sections 5 and 11, Article II of Republic Act No. 9165. The Court of Appeals affirmed. On appeal, the Supreme Court reversed and acquitted him.

The Issue: Did the Missing DOJ Representative Break the Chain?

The central question was whether the prosecution sufficiently proved the identity and integrity of the seized drugs despite the absence of a DOJ representative during the inventory and photography.

The Ruling: Unjustified Deviation Warrants Acquittal

The Supreme Court ruled in favor of the accused. The Court emphasized that in drug cases, the dangerous drug itself is the corpus delicti of the crime. The prosecution must establish its identity with moral certainty by accounting for every link in the chain of custody—from seizure to presentation in court.

Under Section 21, Article II of RA 9165, the inventory and photography must be conducted in the presence of the accused or his representative, and certain required witnesses: a representative from the media and the DOJ, and any elected public official. (After RA 10640 amended the law in 2014, the requirement became an elected public official and a representative of the National Prosecution Service or the media.)

The Court acknowledged that strict compliance may not always be possible due to field conditions. However, the "saving clause" only applies if the prosecution proves two things: (1) a justifiable ground for non-compliance, and (2) that the integrity and evidentiary value of the seized items were properly preserved. The prosecution must explain the reasons for the procedural lapse—the Court cannot presume these grounds exist.

In this case, the prosecution never acknowledged, much less justified, the absence of a DOJ representative. The arresting officer admitted on cross-examination that no DOJ representative came to the police station, but offered no explanation. The prosecution also failed to conduct re-direct examination to address the oversight.

The Court also reminded prosecutors that the State has a positive duty to account for any lapses in the chain of custody, regardless of whether the defense raises the issue at trial. This duty exists because the requirements are clearly set forth in the law, and the penalties for drug offenses can be life imprisonment.

Practical Takeaways

• Chain of custody is substantive law, not mere procedure. Police must strictly comply with Section 21, Article II of RA 9165, including the required witnesses during inventory and photography.
• The saving clause has limits. Non-compliance is excused only when the prosecution proves a justifiable ground and shows the drugs' integrity was preserved. Mere statements of unavailability are not enough.
• Police must prepare in advance. Officers have time before a buy-bust operation to arrange for the required witnesses. Genuine and sufficient efforts to secure their presence must be shown.
• Prosecutors must proactively address lapses. The State cannot wait for the defense to raise chain of custody issues. Unexplained procedural gaps can result in acquittal even on appeal.
• For the accused, a broken chain can mean freedom. When the prosecution fails to prove the identity and integrity of the seized drugs beyond reasonable doubt, the proper remedy is acquittal.
