When a Drug Sale Is Only Attempted: Key Lessons from People v. Tumulak

In criminal prosecutions for illegal sale of dangerous drugs, the prosecution must prove more than just an agreement to sell. It must show that the seller actually delivered the illicit drug to the buyer. In People v. Tumulak (G.R. No. 206054, July 25, 2016), the Supreme Court clarified this rule and modified a conviction for consummated illegal sale into one for attempted sale, because the seller never handed over the drugs.

The case also offers practical guidance on the chain of custody rule under Section 21 of Republic Act No. 9165, the Comprehensive Dangerous Drugs Act of 2002.

The Facts of the Case

On July 31, 2002, agents of the National Bureau of Investigation (NBI) conducted a buy-bust operation against Minnie Tumulak for the sale of thirty ecstasy tablets. Special Investigator Arthur Oliveros acted as the poseur-buyer.

At a café, Tumulak showed Oliveros one tablet as a sample. When Oliveros asked for the remaining twenty-nine tablets, Tumulak demanded the P60,000.00 payment first so she could count the money in the restroom. Oliveros handed over the envelope containing the marked bills and boodle money. As Tumulak headed to the restroom, the NBI agents arrested her and recovered all thirty tablets from her bag.

The Regional Trial Court convicted Tumulak of consummated illegal sale of dangerous drugs. The Court of Appeals affirmed. On appeal, the Supreme Court modified the conviction to attempted sale.

When Is a Drug Sale Consummated?

The Court reiterated that the elements of illegal sale of dangerous drugs are: (1) proof that the transaction took place, and (2) presentation in court of the corpus delicti, or the illicit drug itself.

To prove the transaction, the prosecution must establish the identity of the buyer and seller, the object and consideration, and—critically—the delivery of the thing sold and the payment. The sale is consummated the moment the buyer actually receives the drug from the seller.

In this case, Tumulak never delivered the thirty tablets to Oliveros. She only showed him one sample tablet, which she then placed back inside her bag. The tablets were confiscated only upon her arrest. Because the element of delivery was missing, the sale was never consummated.

The Attempted Sale Was Established

The Court applied the rule on variance under Rule 120, Sections 4 and 5 of the Rules of Court. While Tumulak could not be convicted of consummated illegal sale, she could be convicted of attempted sale, which is necessarily included in the offense charged.

Under Article 6 of the Revised Penal Code, a felony is attempted when the offender commences its commission by overt acts but fails to perform all the acts of execution due to a cause other than spontaneous desistance.

Here, Tumulak's overt acts—showing the sample tablet and demanding payment before delivery—clearly established her intent to sell. The sale was aborted only because the NBI agents arrested her. That is a cause other than her own spontaneous desistance.

The Court convicted her of attempted sale under Section 26, in relation to Section 5, of R.A. No. 9165, imposing life imprisonment and a fine of P500,000.00.

Chain of Custody: Substantial Compliance Suffices

Tumulak also argued that the prosecution failed to comply with Section 21 of R.A. No. 9165, which requires physical inventory and photographing of seized drugs in the presence of certain public officials.

The Court acknowledged the lapses but applied the saving clause in the Implementing Rules and Regulations. Noncompliance will not invalidate the seizure if the prosecution recognizes the procedural lapse, explains justifiable grounds, and proves that the integrity and evidentiary value of the seized items were preserved.

In this case, the NBI agent marked the three sachets at the station, not at the place of arrest. The Court found this sufficient, noting that marking at the nearest police station is acceptable and that marking inside a crowded restaurant was impractical. The drugs were properly turned over to the forensic laboratory, and the analyst certified they tested positive for methylenedioxymethamphetamine (ecstasy).

The Court emphasized that what matters most is preserving the integrity and evidentiary value of the seized drugs, not a perfect chain of custody.

Practical Takeaways

• Delivery is essential. For a conviction of illegal sale of dangerous drugs, the prosecution must prove that the buyer actually received the drug from the seller. Merely showing a sample or agreeing to sell is not enough.
• Attempted sale is a fallback. When the sale is not consummated, the accused may still be convicted of attempted sale if overt acts and intent to sell are proven, and the sale was aborted for reasons other than the accused's own desistance.
• Chain of custody is about integrity. Minor lapses in the Section 21 procedure—such as marking at the station instead of the arrest site—will not automatically render seized drugs inadmissible if the prosecution explains the lapse and proves the drugs' integrity was preserved.
• Presumption of regularity is lost on noncompliance. When the prosecution admits procedural lapses, it can no longer rely on the presumption of regularity and must instead prove with moral certainty that the drugs presented in court are the same ones seized from the accused.
