Entrapment vs Instigation: Defining the Boundaries of Drug Law Enforcement in the Philippines

The line between lawful entrapment and prohibited instigation is one of the most frequently contested issues in Philippine drug prosecutions. In People v. Abella y Sedego (G.R. No. 213918, June 27, 2018), the Supreme Court Third Division had the opportunity to restate this crucial distinction while reviewing the convictions of two women charged with illegal sale and possession of shabu under Republic Act No. 9165. The ruling affirms that a valid buy-bust operation remains a legitimate law enforcement technique, provided the criminal intent originates from the accused and not from the police.

The Facts of the Case

On January 19, 2009, operatives of the Philippine Drug Enforcement Agency (PDEA) in Dumaguete City conducted a buy-bust operation against Evangeline Abella and Mae Ann Sendiong based on information from a confidential informant. A PDEA asset, Urseevi Tubio, acted as the poseur-buyer. Tubio approached the accused-appellants and expressed his desire to buy shabu. Abella agreed to sell, received the marked money, and handed it to Sendiong, who then gave Abella a sachet of shabu, which was in turn delivered to Tubio.

After the transaction was consummated, the buy-bust team moved in and arrested both women. A search of Sendiong yielded a second sachet of shabu hidden in a key holder. Laboratory examination confirmed both sachets contained 0.01 gram of methamphetamine hydrochloride each. The trial court convicted both accused of illegal sale, and Sendiong was additionally convicted of illegal possession. The Court of Appeals affirmed, and the accused appealed to the Supreme Court.

The Issue: Entrapment or Instigation?

The accused-appellants argued that the operation constituted instigation, not entrapment. They claimed that Tubio convinced them to sell shabu, and that without his inducement, they would not have committed the crime. Abella also questioned the absence of a police officer beside the poseur-buyer during the transaction.

The Supreme Court rejected these arguments. The Court reiterated the well-settled distinction: instigation occurs when the police lure a person into committing a crime he had no intention to commit, while entrapment involves the use of ruses and schemes to capture a lawbreaker whose criminal intent originated in his own mind. In instigation, law enforcers act as active co-principals and the accused must be acquitted; in entrapment, prosecution and conviction are proper.

Applying this test, the Court found that the accused-appellants voluntarily and knowingly transacted with Tubio. The fact that Sendiong already possessed another sachet of shabu, and that a surveillance operation the previous day confirmed they were openly selling drugs, demonstrated their predisposition to commit the crime. The buy-bust team merely facilitated their apprehension. The Court also noted that the presence of a police officer beside the poseur-buyer is neither an element of the offense nor a requirement for conviction.

The Chain of Custody Requirement

The Court also addressed Abella's challenge to the chain of custody of the seized drugs. Under Section 21 of RA 9165, the prosecution must establish an unbroken chain of custody to prove the identity and integrity of the corpus delicti—the dangerous drug itself. The Court outlined the four links: (1) seizure and marking of the drug by the apprehending officer; (2) turnover to the investigating officer; (3) turnover to the forensic chemist for examination; and (4) turnover to the court.

In this case, the Court found all four links were properly established. The arresting officer marked the sachets immediately after seizure, an inventory was conducted at the scene in the presence of the accused and required witnesses, the items were submitted to the laboratory the same day, and the forensic chemist personally delivered them to the trial court. The Court also rejected the argument that the forensic chemist's use of masking tape to reseal the sachets compromised their integrity, noting that adhesive tape is merely one means of preservation, and other measures—such as keeping the items in a locked cabinet with restricted access—sufficed.

The Ruling

The Supreme Court dismissed the appeal and affirmed the convictions. Abella and Sendiong were found guilty of illegal sale of shabu under Section 5, Article II of RA 9165, each sentenced to life imprisonment and fined P500,000.00. Sendiong was additionally convicted of illegal possession under Section 11, sentenced to an indeterminate penalty of 12 years and one day to 14 years, and fined P400,000.00.

Practical Takeaways

• Entrapment is valid; instigation is not. The critical question is whether the criminal intent originated from the accused (entrapment) or from the police (instigation). Courts will examine the accused's predisposition to commit the crime, including prior surveillance and evidence of drug dealing activity.
• A poseur-buyer need not be a police officer. PDEA assets and civilian informants may validly act as poseur-buyers, and their absence of a police escort during the transaction does not invalidate the operation.
• Chain of custody is a strict requirement. The prosecution must account for every link from seizure to court presentation. However, minor deviations, such as the type of tape used to reseal evidence, will not automatically result in acquittal if the integrity of the drugs is otherwise preserved.
• Presumption of regularity applies to buy-bust teams. Unless the accused presents clear and convincing evidence of improper motive or irregular conduct, courts will presume that law enforcement officers regularly performed their duties.
