Chain of Custody Rule: Why Missing Media Witness Led to Acquittal in Drug Sale Case

The Supreme Court has long emphasized that in drug cases, the prosecution must prove not only that the accused sold or possessed illegal drugs, but also that the drugs presented in court are the very same items seized from the accused. In People v. Dela Cruz and Bautista (G.R. No. 225741, December 5, 2018), the Court reversed a conviction for illegal sale of shabu because the police failed to justify the absence of a required witness during the inventory and photography of the seized item. The case is a clear reminder that procedural rules on chain of custody are substantive law, not mere technicalities.

The Facts of the Case

On August 1, 2012, police officers in Bambang, Nueva Vizcaya conducted a buy-bust operation against Brandon Dela Cruz and James Francis Bautista. The officers 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 done at the police station, witnessed by a municipal councilor and a Department of Justice (DOJ) representative. No media representative was present.

The accused denied the charges, claiming they were arrested by armed men who searched their house and planted the drugs. The Regional Trial Court convicted them, and the Court of Appeals affirmed. The Supreme Court, however, acquitted them.

The Issue

The sole question was whether the Court of Appeals correctly upheld the conviction despite the prosecution's failure to comply with the chain of custody rule under Section 21, Article II of Republic Act No. 9165, the Comprehensive Dangerous Drugs Act of 2002.

The Chain of Custody Rule

The Court explained that in illegal sale and illegal possession of dangerous drugs cases, the dangerous drug itself forms the corpus delicti of the crime. The prosecution must therefore establish the identity of the drug with moral certainty by accounting for each link in the chain of custody—from seizure to presentation in court.

Under Section 21 of RA 9165, as it stood before amendment by RA 10640, the physical inventory and photography of seized items must be conducted in the presence of the accused or his representative, and three required witnesses: a representative from the media, a representative from 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 marking may be done at the nearest police station rather than at the place of arrest. However, the witness requirement is strictly enjoined. Non-compliance may be excused only 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. The prosecution must explain the reasons for the procedural lapse, and the justifiable ground must be proven as a fact—the Court cannot presume it.

Why the Conviction Was Reversed

In this case, the inventory showed only an elected official and a DOJ representative were present. No media representative attended. The prosecution claimed in its pre-trial brief that "no media representatives were present despite efforts to secure their presence," but presented no evidence to substantiate this claim.

The Supreme Court found this general averment insufficient. The prosecution failed to show that the apprehending officers exerted genuine and sufficient efforts to secure a media representative. Mere statements of unavailability, without actual serious attempts to contact the required witnesses, are unacceptable as justifications. Because the deviation from the chain of custody rule was unjustified, the Court concluded that the integrity and evidentiary value of the seized item were compromised, warranting acquittal.

Practical Takeaways

• Compliance is substantive, not procedural. The chain of custody rule protects accused persons from police abuse, especially where the penalty can be life imprisonment. Courts will not treat lapses lightly.

• Document the efforts. If a required witness is unavailable, the prosecution must present concrete evidence of genuine efforts to secure their presence—not just a bare allegation in a brief.

• Know the witness requirements. Before RA 10640 (July 15, 2014), the required witnesses were a media representative, a DOJ representative, and an elected public official. After the amendment, the requirement is an elected public official and a representative of the National Prosecution Service or the media.

• Prepare before the operation. Police officers have time from receiving information about drug activities until the arrest to arrange for the presence of required witnesses. Failure to do so is difficult to excuse.

• For the defense, scrutinize the chain. The prosecution has the positive duty to account for any lapses in the chain of custody, even if the defense does not raise them at trial. This duty can be a powerful ground for acquittal on appeal.
