Indeterminate Sentence Law Clarifying Penalties for Drug Possession

The Supreme Court's 2010 decision in People v. Marcelino offers important guidance on how courts compute prison terms for drug possession under the Comprehensive Dangerous Drugs Act of 2002 (RA 9165). The case also clarifies when police may conduct warrantless arrests through buy-bust operations and what happens when officers fail to strictly follow evidence-preservation rules.

The Facts of the Case

Elizabeth Marcelino was arrested on October 31, 2002, in Bulacan after a buy-bust operation. A police officer acting as poseur-buyer purchased shabu worth PhP 500 from her. After the sale, another officer recovered the marked money and an additional sachet of shabu weighing 3.296 grams from her person.

Marcelino was charged with two crimes: illegal sale of dangerous drugs under Section 5 of RA 9165 and illegal possession of dangerous drugs under Section 11 of the same law. She pleaded not guilty and claimed she was arrested at home without a warrant, not through a legitimate buy-bust operation.

The Issue Before the Court

Marcelino raised two main arguments on appeal. First, she claimed the police should have secured a search warrant and warrant of arrest before conducting the operation, since they had already conducted two test-buys beforehand. Second, she argued that the police failed to comply with the inventory and photograph requirements under Section 21 of RA 9165, which should have made the seized evidence inadmissible.

The Court's Ruling on Warrantless Arrests

The Supreme Court rejected Marcelino's arguments and affirmed her conviction. On the warrant issue, the Court cited People v. Villamin (G.R. No. 175590, February 9, 2010), which held that a buy-bust operation is a valid form of entrapment and falls under the warrantless arrest exception in Section 5(a), Rule 113 of the Rules of Court.

The Court explained that in a buy-bust operation, the idea to commit the crime comes from the accused, not from the police. The accused is caught in the act of selling illegal drugs, so the arrest is made on the spot. The seizure of evidence then becomes valid as a search incidental to a lawful arrest under Section 13, Rule 126 of the Rules of Court.

The Chain of Custody Requirement

On the evidence-preservation issue, the Court ruled that failure to strictly comply with Section 21 of RA 9165's Implementing Rules and Regulations is not automatically fatal to the prosecution's case. What matters is whether the integrity and evidentiary value of the seized items were preserved.

In this case, the Court found an unbroken chain of custody. The officer marked the seized sachets, a request for laboratory examination was signed and received by the crime laboratory, the Chemistry Report confirmed the items were shabu, and the marked items were presented in court. The Court also applied the presumption of regularity in favor of police officers, which Marcelino failed to overcome.

The Penalty for Drug Possession

The most instructive part of the decision concerns the penalty for possession. Under Section 11(5) of RA 9165, possessing less than five grams of shabu carries a penalty of twelve (12) years and one (1) day to twenty (20) years of imprisonment, plus a fine of PhP 300,000 to PhP 400,000.

The trial court sentenced Marcelino to imprisonment of twelve (12) years and one (1) day, as the minimum term, to thirteen (13) years, as the maximum term, applying the Indeterminate Sentence Law. The Supreme Court affirmed this sentence as within the range provided by RA 9165.

This illustrates a key point: when a statute prescribes a range of penalties, courts apply the Indeterminate Sentence Law to set both a minimum and maximum term. The minimum is typically the lowest penalty prescribed, while the maximum is fixed by the court based on the circumstances of the case.

Practical Takeaways

• Buy-bust operations are legitimate law enforcement tools that do not require prior warrants, because the accused is caught committing the crime in the presence of police officers.
• Evidence seized during a lawful buy-bust is admissible as a search incidental to a lawful arrest.
• Minor non-compliance with Section 21 of RA 9165 on inventory and photography will not automatically acquit an accused if the chain of custody remains intact and the evidence's integrity is preserved.
• For possession of less than five grams of shabu, the penalty ranges from twelve years and one day to twenty years, plus a fine of PhP 300,000 to PhP 400,000.
• Under the Indeterminate Sentence Law, courts impose both a minimum and maximum prison term within the range set by the statute.
