Case Summary (G.R. No. 95357)

Factual Background

The prosecution alleged that police officers of Laoag City, led by Senior Police Officer Four Rovimanuel Balolong, executed Search Warrant No. 05-2012 at petitioner’s residence in Barangay 14, Fonacier Street, Laoag City on May 22, 2012. The warrant authorized search of petitioner’s bedroom and a Mitsubishi Pajero parked in the garage for “an undetermined volume of shabu.” Upon entry, police knocked on petitioner’s bedroom; petitioner opened the door, was allowed to dress, and stepped into the living room with his common-law wife while the bedroom door was secured. Barangay Chairman Felix Ayson and media representatives were later summoned to witness the search. During the search, petitioner’s mother, Gwendolyn, allegedly slipped out of the bedroom holding a bundle wrapped in white cloth which she asserted SPO4 Balolong had thrown under the bed; SPO4 Balolong retrieved the bundle and produced what he said were plastic sachets containing white crystalline substance. Police officers also found, inside the bedroom, a small black box labeled “safety can be fun” containing cut aluminum foils and lighters, and inside the Pajero, under the passenger-side floor mat, a white carton containing cut aluminum foils, empty plastic sachets, and one large heat-sealed plastic sachet with white crystalline substance. The items were photographed, marked by police, inventoried, and submitted to the Ilocos Norte Crime Laboratory. The forensic chemist’s qualitative examination tested positive for methamphetamine hydrochloride in the sachets amounting to 14.7717 grams for the large sachet and 0.6006 gram aggregate for ten small sachets.

Procedural History and Trial Court Proceedings

Separate Informations were filed, charging petitioner with Illegal Possession of Dangerous Drugs under Section 11, Article II of RA 9165 (Crim. Case No. 15244) and Illegal Possession of Drug Paraphernalia under Section 12, Article II of RA 9165 (Crim. Case No. 15243). Petitioner denied the charges, claimed the items were planted, contested ownership of the vehicle, and assailed the legality of the search warrant on grounds that the deponent had ill motive. In a Decision dated December 8, 2014, the RTC found petitioner guilty of both offenses, sentenced him to life imprisonment with a fine of P300,000 for illegal possession of dangerous drugs, and imposed an indeterminate penalty of six months and one day to two years with a fine of P10,000 for illegal possession of drug paraphernalia. The RTC held that petitioner waived objections to the search warrant by participating in arraignment and trial, found the warrant properly issued after searching questions, and determined that the chain of custody was preserved; it rejected the defense of frame-up as not credible.

Court of Appeals Ruling

The Court of Appeals affirmed with modification in a Decision dated June 28, 2017, increasing the fine for illegal possession of dangerous drugs to P500,000. The CA concluded that the RTC properly determined probable cause for the warrant and properly implemented it, and that the chain of custody was preserved despite discrepancies in reported weights which, the CA explained, resulted from police officers obtaining a copy of the laboratory report belatedly. The CA found petitioner’s planting theory self-serving and unconvincing. A motion for reconsideration was denied by CA Resolution dated January 22, 2018.

The Parties’ Contentions on Appeal

Petitioner urged that the search warrant was invalid because the applicant’s testimony rested on hearsay and therefore did not establish probable cause. He further argued that implementation of the warrant was irregular due to alleged failure of the police to properly identify themselves, to read or explain the warrant in a language understood by the person who answered the door, and because of a show of force. Petitioner maintained that the seized items were planted, highlighted inconsistencies concerning the number of small sachets and markings on seized items, challenged the chain of custody, and pointed to absence of a Department of Justice representative during inventory. The prosecution and the courts below maintained that the warrant was supported by a confidential asset’s first-hand test buy corroborated by surveillance, that the police properly implemented the warrant, and that Section 21, Article II of RA 9165 had been complied with so as to preserve the integrity of the seized items.

Issues Presented to the Supreme Court

The central issue was whether the Court of Appeals erred in affirming petitioner’s conviction for violation of Sections 11 and 12, Article II of RA 9165. Ancillary issues included the validity of the search warrant, the regularity of its implementation, and the integrity of the chain of custody of the seized items.

Supreme Court Disposition

The Supreme Court granted the petition. It reversed and set aside the decisions of the Court of Appeals and the Regional Trial Court and acquitted Damacen Gabriel Cunanan a.k.a. "Ryan" of the charged offenses. The Court ordered the Director of the Bureau of Corrections to effect petitioner’s immediate release unless lawfully detained for another reason.

Legal Basis and Reasoning — Probable Cause and Implementation

The Court reiterated that appellate review in criminal cases is plenary and may correct errors in the appealed judgment whether assigned or not. On the validity of the search warrant, the Court found no reversible error. It accepted that the judge who issued the warrant had a substantial basis to find probable cause because SPO4 Balolong’s testimony was corroborated by the confidential asset who testified under oath that he conducted a positive “test buy,” and because the police had conducted surveillance. The Court relied on precedents, including People v. Zen Hua and People v. Tee, to hold that information from a reliable informant corroborated by surveillance sufficed to establish probable cause and that magistrates’ determinations enjoy deference where supported by substantial basis. The Court also rejected petitioner’s implementation objections as insufficient to invalidate the search. Police testimony and barangay chairman testimony established that officers identified themselves, announced their purpose, and that the search warrant was read and explained; the mere fact that officers carried firearms did not invalidate the search absent evidence of improper motive.

Legal Basis and Reasoning — Chain of Custody and Evidentiary Integrity

Although the warrant and its execution were upheld, the Court identified fatal deficiencies in the prosecution’s proof of the integrity and identity of the seized corpus delicti. The Court emphasized that for dangerous drugs the prosecution must show an unbroken chain of custody from seizure to laboratory receipt, safekeeping, and presentation in court. The Court found multiple lapses:

  • A discrepancy in testimony as to whether the bundle retrieved from under the bed contained nine or ten small sachets of shabu, with photographic evidence showing nine sachets while several documents and later testimony referenced ten. The prosecution made no effort to reconcile the inconsistency, and the RTC’s dismissal of the discrepancy as immaterial was insufficient given petitioner’s claim of planting.
  • Inconsistent markings: SPO4 Balolong testified he marked the sachets with his initials but various records and the laboratory report reflected differing initials (“RB” rather than “RVB”), and no satisfactory explanation was offered for the inconsistency.
  • Failure to properly mark or to identify seized paraphernalia: PO1 Ventura who found the black box and foils could not identify markings and testified he relied on SPO4 Ancheta’s marking, yet could not identify the items in court except by the box label and lighter color; the initial custodial marking is the starting point of the chain and its absence or ambiguity fatally undermined continuity.
  • Omission from inventory: SPO4 Balolong testified that a sachet was found in the Pajero, yet that particular item did n
