Compromised Evidence Acquittal in Drug Case Due to Chain of Custody Lapses

The Supreme Court has overturned the conviction of two men charged with illegal sale of dangerous drugs, ruling that the prosecution's failure to justify the absence of a required witness during the inventory and photography of seized evidence compromised the integrity of the corpus delicti. The case underscores that strict compliance with the chain of custody rule under Republic Act No. 9165 is a matter of substantive law, not mere procedure.

The Case

Brandon Dela Cruz and James Francis Bautista were arrested on August 1, 2012, during a buy-bust operation by the Bambang Police Station in Nueva Vizcaya. Police recovered 0.029 gram of white crystalline substance later confirmed to be methamphetamine hydrochloride, or shabu. The marking, inventory, and photography of the seized item were conducted at the police station in the presence of a municipal councilor and a Department of Justice (DOJ) representative. No media representative was present.

The Regional Trial Court convicted the accused of illegal sale of dangerous drugs under Section 5, Article II of RA 9165, sentencing them to life imprisonment and a fine of P500,000. The Court of Appeals affirmed the conviction, ruling that the absence of a media representative did not affect the integrity of the evidence since a DOJ representative and an elected official witnessed the proceedings.

The Issue

Whether the Court of Appeals correctly upheld the conviction despite the prosecution's failure to comply with the witness requirement under the chain of custody rule.

The Ruling

The Supreme Court reversed the conviction and acquitted both accused. The Court held that in drug cases, the identity of the dangerous drug must be established with moral certainty because the 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.

Under Section 21, Article II of RA 9165, the inventory and photography of seized items must be conducted in the presence of the accused or his representative, and required witnesses. Before the amendment by RA 10640, these witnesses were: a representative from the media AND the DOJ, and any elected public official. The presence of these witnesses ensures the chain of custody is established and removes any suspicion of switching, planting, or contamination of evidence.

The Court acknowledged that non-compliance may be excused under the saving clause if the prosecution proves: (a) a justifiable ground for non-compliance, and (b) that the integrity and evidentiary value of the seized items were properly preserved. However, the prosecution must duly explain the reasons behind procedural lapses, and these justifiable grounds must be proven as a fact — the Court cannot presume their existence.

In this case, the prosecution merely stated in its Pre-Trial Brief that no media representatives were present despite efforts to secure their presence. The Court found this general averment insufficient. There was no evidence of genuine and sufficient efforts to secure a media representative. Mere statements of unavailability, absent actual serious attempts to contact required witnesses, are unacceptable as justified grounds for non-compliance.

The Court emphasized that police officers are ordinarily given sufficient time — from receiving information about the accused's activities until the arrest — to prepare for a buy-bust operation and make necessary arrangements beforehand, knowing they must strictly comply with the chain of custody rule.

Practical Takeaways

• The chain of custody rule under Section 21, RA 9165 is substantive law, not a mere technicality. Courts will not hesitate to acquit when the rule is violated without justification.
• Prosecutors must proactively account for any lapses in the chain of custody, even if the defense does not raise the issue at trial. The State has a positive duty to explain procedural deviations.
• A bare allegation that efforts were made to secure required witnesses is insufficient. The prosecution must present concrete evidence of genuine attempts to contact media representatives, DOJ representatives, and elected officials.
• For drug cases before RA 10640 (July 15, 2014), the presence of a media representative AND a DOJ representative AND an elected public official was required. After RA 10640, the requirement is an elected public official and either a National Prosecution Service representative or a media representative.
• The saving clause applies only when the prosecution proves justifiable grounds for non-compliance and demonstrates that the integrity of the seized drugs was preserved. Both elements must be established as facts.
