Challenging Searches and Protecting Rights Against Unlawful Intrusion in Drug Cases

The Supreme Court, in People v. Romorosa (G.R. No. 237209, April 10, 2019), reaffirmed the strict standards for proving the identity and integrity of seized drugs in buy-bust operations. The ruling clarifies what the prosecution must show to establish an unbroken chain of custody, and it addresses common defense arguments about missing witnesses and procedural lapses. For anyone facing drug charges—or for lawyers defending them—this case is a vital guide to what evidence truly matters.

The Facts of the Case

On February 20, 2010, agents of the National Bureau of Investigation (NBI) conducted a buy-bust operation in Muntinlupa City. A confidential informant had arranged a shabu deal worth P12,000.00 with a certain "Omar." The poseur-buyer, Special Investigator Rolan Fernandez, and the informant entered a house where a woman named "Lyn"—later identified as Catherine Romorosa—handed over two plastic sachets of shabu in exchange for marked money.

The team arrested Romorosa and two male companions, Mohamad Dampak and Jamil Dampak. Each of the men was found with one sachet of shabu. Due to a gathering crowd, the team left the scene and conducted the marking, inventory, and photograph-taking at the NBI office instead. A media representative was present, but no barangay official or Department of Justice (DOJ) representative arrived despite being contacted.

Romorosa was charged with illegal sale of dangerous drugs under Section 5, Article II of Republic Act No. 9165. The Regional Trial Court convicted her, and the Court of Appeals affirmed. She appealed to the Supreme Court.

The Issues Raised on Appeal

Romorosa raised two main arguments. First, she claimed that the prosecution's key witness, SI Fernandez, gave inconsistent accounts of how the drug deal was arranged. In his testimony, he said the informant had transacted the deal with Omar; but in the Joint Affidavit of Arrest, it stated that SI Fernandez himself "closed a deal" for the purchase of shabu.

Second, she argued that the prosecution failed to prove the corpus delicti—the body of the crime—because the shabu was never turned over to the NBI's evidence custodian. Instead, the forensic chemist kept it in his steel cabinet until it was presented in court. She claimed this gap in the chain of custody made the drug's integrity doubtful.

The Court's Ruling: No Fatal Inconsistency

The Supreme Court dismissed the appeal and affirmed the conviction. On the first issue, the Court found no real contradiction. The phrase "close a deal" in the affidavit referred to the actual consummation of the sale during the buy-bust operation itself, not to the prior arrangement made by the informant. The informant had merely set up the transaction; SI Fernandez completed it as the poseur-buyer.

The Court emphasized that a minor discrepancy in a witness's account does not destroy credibility when the substance of the testimony is consistent. Romorosa's bare denial, pitted against the affirmative testimony of law enforcement officers with unsullied credibility, could not prevail.

The Chain of Custody Rule

On the second issue, the Court applied the four essential links in the chain of custody established in People v. Kamad:

1. Seizure and marking of the illegal drug recovered from the accused by the apprehending officer;
2. Turnover of the drug by the apprehending officer to the investigating officer;
3. Turnover by the investigating officer to the forensic chemist for laboratory examination; and
4. Turnover and submission of the marked drug by the forensic chemist to the court.

In this case, all four links were proven. SI Fernandez took custody of the two sachets immediately after the buy-bust, marked them at the NBI office, and turned them over to another agent who prepared the inventory. The forensic chemist received them, tested them positive for shabu, and kept them in his locked steel cabinet until producing them in court.

The Forensic Chemist as Safekeeper

The Court rejected Romorosa's argument that the forensic chemist's failure to turn over the drugs to an evidence custodian broke the chain. Section 21 of R.A. No. 9165 does not prescribe any particular intermediary between the forensic chemist and the court. Neither does it prohibit the chemist from safekeeping the specimens pending transmission to court.

What matters, the Court said, is evidence of how the officer actually performed his duty as safekeeper. Here, the forensic chemist testified that he alone had the key to his steel cabinet, that the seals remained intact, and that the markings were unchanged. This was sufficient to assure the Court that the drugs were never altered or substituted.

Practical Takeaways

• The chain of custody has four links. Prosecutors must prove each link: seizure and marking, turnover to the investigating officer, turnover to the forensic chemist, and submission to the court. A missing link can be fatal to the case.
• Minor inconsistencies do not automatically destroy credibility. Courts look at the substance of a witness's testimony, not isolated phrases. A "close the deal" statement in an affidavit can coexist with a testimony that an informant arranged the deal.
• The forensic chemist may keep custody of the drugs. There is no legal requirement that an evidence custodian must hold the drugs between examination and court presentation. What matters is proof that the safekeeper preserved their integrity.
• Document every step. Marking, inventory, and photographing should be done at the scene if practicable. If not, the reason must be explained, as the Court accepted here due to the gathering crowd.
• Denial is weak against credible police testimony. A bare denial cannot overcome the affirmative testimony of law enforcement officers whose credibility is intact.
