Entrapment vs. Instigation: Protecting Rights in Drug-Related Arrests

In a 2015 decision, the Supreme Court had the opportunity to clarify an important distinction in Philippine criminal law: the difference between entrapment, which is a valid law enforcement technique, and instigation, which is a prohibited form of inducement that can result in an acquittal. This distinction is critical in drug-related arrests, where buy-bust operations are the standard method of apprehending sellers of prohibited substances.

The case of People v. Rosauro (G.R. No. 209588, February 18, 2015) also reaffirms the rules on the chain of custody of seized drugs under Republic Act No. 9165, the Comprehensive Dangerous Drugs Act of 2002.

The Facts of the Case

Eric Rosauro was charged with illegal sale of shabu under Section 5, Article II of R.A. 9165. The prosecution alleged that on July 3, 2004, police officers from the Provincial Anti-Illegal Drugs Special Operation Task Unit conducted a buy-bust operation in Villanueva, Misamis Oriental. A confidential informant acted as the poseur-buyer and purchased one sachet of shabu from Rosauro in exchange for a marked P100.00 bill. After the transaction, the police arrested Rosauro and recovered the marked money.

Rosauro, however, claimed he was a victim of instigation. He testified that the police asset went to his house four times and convinced him to run an errand. The informant gave him money to buy shabu from a certain "Kael" and to deliver it to the informant's house. Rosauro claimed he was arrested upon delivering the drugs, and that the sachet was recovered not from him but from the informant.

The Issue: Entrapment or Instigation?

The central question was whether the operation was a valid entrapment or a prohibited instigation.

The Court explained the distinction. In entrapment, the police merely provide the opportunity for the accused to commit a crime that he or she is already predisposed to commit. In instigation, on the other hand, the police actively induce or lure an innocent person into committing a crime he or she had no intention of committing.

Applying this to the case, the Court ruled that what transpired was valid entrapment. The police had received intelligence reports that Rosauro was habitually dealing in illegal drugs. The informant's solicitation merely furnished evidence of a course of conduct. There was no showing that the informant induced Rosauro to sell drugs; rather, the operation only provided the opportunity for him to do so.

The Chain of Custody Rule

Rosauro also argued that the prosecution failed to prove the corpus delicti (the body of the crime) and that the safeguards under Section 21 of R.A. 9165 were not followed.

Section 21 requires that the apprehending team, immediately after seizure, physically inventory and photograph the seized drugs in the presence of the accused or his representative, a media representative, a DOJ representative, and an elected public official.

The Court acknowledged that while the chain of custody should ideally be perfect, it is "almost always impossible to obtain an unbroken chain" in practice. The most important factor is the preservation of the integrity and evidentiary value of the seized items. Non-compliance with the prescribed physical inventory and photographing will not render the arrest illegal or the items inadmissible, as long as the integrity of the seized drugs is properly preserved.

In this case, the Court found that the chain of custody was properly established. The poseur-buyer handed the sachet to SPO4 Larot, who marked it "Exhibit A." The item was then brought to the police station, where a Certificate of Inventory and a Request for Laboratory Examination were prepared. The specimen was turned over to the PNP Crime Laboratory, and the Forensic Chemical Officer confirmed it was positive for methamphetamine hydrochloride. The officer who seized the item also identified it in open court.

The Ruling

The Supreme Court affirmed the conviction. All the elements of illegal sale of dangerous drugs were present: the identity of the buyer and seller, the object of the sale, the consideration, and the delivery of the drug and receipt of payment. The penalty of life imprisonment and a fine of P500,000.00 was upheld.

Practical Takeaways

• Entrapment is legal; instigation is not. Police may set up a buy-bust to catch a suspected drug seller, but they cannot plant the criminal intent in an innocent person's mind.
• The non-presentation of a confidential informant is not fatal to a drug case, especially when the arresting officers can testify to the transaction.
• Strict compliance with Section 21 of R.A. 9165 is ideal but not absolute. The key is preserving the integrity of the seized drugs and establishing an unbroken chain of custody.
• For the accused, the defense of instigation is difficult to prove and requires clear evidence that the police induced the commission of the crime.
• For law enforcement, proper documentation and marking of evidence immediately after seizure remain crucial to a successful prosecution.
