Case Summary (G.R. No. 233480)
Applicable Law
The relevant law governing this case is the Comprehensive Dangerous Drugs Act of 2002, specifically Republic Act No. 9165, particularly Sections 5 and 11 which penalize illegal sale and illegal possession of dangerous drugs.
The Facts
Two informations were filed against Mercader, one for the illegal sale of shabu involving a transaction with Police Officer 1 (PO1) Christopher Anos and another for illegal possession of drugs found during a preventive search post-arrest. The operation was carried out after the police received information regarding drug sales by Mercader and her husband. During the bust, drugs were seized, and after laboratory analysis confirmed the drugs were indeed shabu, prosecution ensued.
The RTC Ruling
The RTC found Mercader guilty beyond a reasonable doubt and imposed a life sentence for the illegal sale of drugs, alongside a fine, and a significant prison sentence for illegal possession. The RTC upheld the prosecution's evidence, primarily the testimonies of the arresting officers, confirming the details of the buy-bust operation. The court dismissed Mercader's defense, characterizing it as lacking in substance.
The CA Ruling
Upon appeal, the CA affirmed the RTC's decision, finding solid evidence of illegal sale and possession. It ruled that the arrest was valid, with all elements of the crimes proven. Furthermore, the CA noted an unbroken chain of custody regarding the seized drugs, indicating proper handling by the arresting officers.

The Court's Ruling
The Supreme Court granted the appeal, concluding that the prosecution failed to establish a proper chain of custody for the seized drugs. The court underscored that procedural lapses occurred, particularly the absence of the required witnesses during the marking and inventory of evidence, which are substantive requirements under the law. This non-compliance was critical, as it jeopardized the integrity and evidentiary value of the seized items, essential for convicting someone of drug-related offenses.
Chain of Custody Requirements
The court emphasized that the integrity of seized items must be proven through proper procedures, as outlined in Section 21 of RA 9165. The absence of a physical inventory, required witnesses (elected officials and representatives from the media or DOJ), and a documented photographic record of the seized items represented significant deviations from protocol. Without compelling justification for these failures, the chain of custody wa
