Chain of Custody and the Death of an Accused: Key Lessons from People v. Maylon

The Supreme Court's resolution in People v. Maylon y Alvero (G.R. No. 240664, June 22, 2020) offers two important lessons for criminal litigation. First, it reiterates the strict requirements for the chain of custody of seized drugs under Republic Act No. 9165. Second, it clarifies what happens when an accused dies while an appeal is pending. Both points matter to anyone facing drug charges or studying how Philippine courts protect the integrity of evidence.

The Facts of the Case

Accused-appellants Jonathan Maylon and Arnel Estrada were charged with illegal sale and illegal possession of dangerous drugs under Sections 5 and 11, Article II of RA 9165. The Regional Trial Court of Marikina City found them guilty, and the Court of Appeals affirmed the conviction. On appeal, the Supreme Court likewise affirmed Maylon's conviction for both illegal sale and illegal possession, and Estrada's conviction for illegal possession.

The prosecution's case rested on the physical evidence — the seized drugs. The defense questioned whether the prosecution had properly preserved the chain of custody, arguing that gaps in the handling of the seized items cast doubt on their identity and integrity.

The Issue

The central issue was whether the prosecution had sufficiently established the chain of custody over the seized drugs, and whether any procedural lapses were fatal to the case. A secondary issue arose when Estrada died while the case was pending before the Supreme Court.

The Ruling on Chain of Custody

The Supreme Court upheld the convictions, adopting the findings of the trial court and the Court of Appeals. The Court found that the prosecution had adequately complied with the chain of custody requirements under RA 9165. The marking, physical inventory, and photographing of the seized items were done in accordance with the law, and the witnesses required by the statute were present.

The Court emphasized that the chain of custody rule exists to ensure that the drugs presented in court are the same drugs seized from the accused. Any break in the chain could render the evidence inadmissible. However, the Court also noted that not every procedural lapse is fatal — what matters is whether the integrity and evidentiary value of the seized items were preserved.

The Ruling on the Death of an Accused

Estrada died on April 26, 2018, before the Court could finally resolve his appeal. Citing (1) of the Revised Penal Code, the Court ruled that criminal liability is totally extinguished by the death of the accused before final judgment. The Court therefore dismissed the criminal case against Estrada and declared it closed and terminated.

The Court also explained, citing People v. Monroyo (G.R. No. 223708, October 9, 2019), that while the criminal liability is extinguished, civil liability may survive if it is based on sources other than the offense itself, such as law, contracts, quasi-contracts, or quasi-delicts. In such cases, the private offended party may file a separate civil action against the estate of the deceased.

Practical Takeaways

• Chain of custody is critical in drug cases. The prosecution must show an unbroken chain from seizure to presentation in court to preserve the integrity of the evidence.
• Procedural lapses are not automatically fatal. Courts look at whether the integrity of the seized items was nonetheless preserved despite minor deviations from the prescribed procedure.
• Death of the accused pending appeal extinguishes criminal liability. Under (1) of the Revised Penal Code, the case is dismissed, and the accused is presumed innocent.
• Civil liability may survive death. If the civil claim is based on a source of obligation other than the crime itself, a separate civil action may still be pursued against the estate.
• For the defense, timely raising chain of custody issues matters. The earlier the objection is made, the better the chance of excluding tainted evidence.
