Unlawful Possession of Firearms: What You Need to Know Under Philippine Law

The Supreme Court recently reaffirmed the rules on unlawful possession of firearms under Republic Act No. 10591, also known as the Comprehensive Firearms and Ammunition Regulation Act. In Reyes v. People (G.R. No. 255668, January 10, 2023), the Court clarified what the prosecution must prove to convict a person of this crime, the penalties involved, and how an acquittal in a related drug case can affect a firearms charge.

The Facts of the Case

In March 2017, police officers in Sta. Maria, Bulacan conducted a buy-bust operation against Jeremy Reyes, who was suspected of selling marijuana. During the operation, the police recovered from Reyes an improvised gun loaded with a live caliber.45 ammunition. A verification with the Firearms and Explosives Office showed that Reyes had no license to possess or carry any firearm.

Reyes was charged with illegal possession of firearms and ammunition under Section 28(a) in relation to Section 28(e)(1) of RA 10591. He was also charged, along with another person, with illegal sale of dangerous drugs. The other accused faced separate drug charges.

The Regional Trial Court convicted Reyes of illegal possession of firearms but acquitted him and the other accused of the drug charges due to the prosecution's failure to prove the chain of custody over the seized drugs. The Court of Appeals affirmed the conviction, and Reyes appealed to the Supreme Court.

The Elements of Illegal Possession of Firearms

To convict a person of illegal possession of firearms, the prosecution must prove two elements:

1. The existence of the firearm — the accused possessed or owned the subject firearm.
2. The absence of a license — the accused does not have the corresponding license for it.

In this case, both elements were established. Reyes was found in possession of an improvised gun loaded with ammunition, and a certification from the Firearms and Explosives Office showed he was not a licensed firearm holder of any kind or caliber.

The Penalty Under RA 10591

Under Section 28(a) of RA 10591, the penalty for illegally possessing a small arm is prision mayor in its medium period, ranging from eight (8) years and one (1) day to ten (10) years.

However, under Section 28(e)(1), the penalty is one degree higher — prision mayor in its maximum period, ranging from ten (10) years and one (1) day to twelve (12) years — if the firearm is loaded with ammunition or inserted with a loaded magazine.

Applying the Indeterminate Sentence Law, the Supreme Court modified Reyes's sentence to an indeterminate period of eight (8) years and one (1) day of prision mayor, as minimum, to ten (10) years, eight (8) months, and one (1) day of prision mayor, as maximum.

Key Ruling: Acquittal in Drug Case Does Not Automatically Mean Acquittal for Firearms

One of the most important points in this decision is the Court's ruling on the relationship between drug charges and firearms charges arising from the same incident.

Reyes argued that since he was acquitted of the drug charges due to breaks in the chain of custody, the firearms charge should also fail. The Supreme Court disagreed.

The Court distinguished this case from Trinidad v. People. In Trinidad, the charge of illegal possession of firearms went into the very transaction for which it was discovered — and that transaction was proved to be illegal. In such a case, an acquittal for the underlying transaction would also result in acquittal for the firearms charge.

But in Reyes, the acquittal on the drug charges was based only on the prosecution's failure to prove the chain of custody over the seized drugs — not on the illegality of the search or the buy-bust operation itself. Since the search was valid, the firearm was admissible in evidence. Each crime has its own corpus delicti, and the failure to prove one crime does not automatically bar the prosecution of another.

The Chain of Custody Rule Does Not Apply to Firearms

The Court also clarified that the strict chain of custody rule under Section 21 of RA 9165 (the Comprehensive Dangerous Drugs Act) applies to illegal drugs — not to firearms.

The chain of custody rule is a mode of authenticating evidence, particularly for amorphous substances like narcotics that are highly susceptible to tampering or planting. Firearms, on the other hand, are unique, readily identifiable, and relatively resistant to change. For such objects, a simple testimony by a witness with knowledge that the evidence is what the proponent claims it to be is sufficient.

In this case, the prosecution properly accounted for the firearm: the officer marked it at the place of arrest in the presence of Reyes and barangay officials, turned it over to the crime laboratory for safekeeping, and identified it during trial.

Practical Takeaways

• Possessing a firearm without a license is a crime under RA 10591, regardless of whether the firearm is homemade or improvised.
• The penalty increases if the firearm is loaded with ammunition or inserted with a loaded magazine.
• The prosecution must prove two things: that the accused possessed the firearm, and that the accused had no license for it.
• An acquittal in a drug case does not automatically mean acquittal in a firearms case if the search was valid and the acquittal was based only on chain of custody issues.
• The strict chain of custody rule applies to drugs, not firearms. A simple identification by a credible witness is enough to authenticate a firearm.
