Evidence Rules in Illegal Firearm Cases: Why Conviction Requires Proof of No License

The Supreme Court's 1996 decision in Mallari v. Court of Appeals (G.R. No. 110569) clarifies an essential rule in illegal possession of firearms cases: the prosecution must prove not only that the accused possessed a firearm, but also that the accused had no license or permit for it. This requirement applies even when the firearm is a homemade "paltik," which some might assume is illegal per se. The ruling also affirms that police officers may make an arrest without physically carrying the warrant, as long as a valid warrant exists.

The Facts of the Case

On December 27, 1990, police officers in Capas, Tarlac received information that Diosdado Mallari, who had a standing warrant of arrest for homicide, was seen in Sitio 14, Sta. Rita. The officers proceeded to the location, surrounded the house, and arrested Mallari. During a search incidental to the arrest, they found a homemade gun (paltik) and one live M-16 ammunition.

Mallari was charged with illegal possession of firearms and ammunition. The Regional Trial Court convicted him, and the Court of Appeals affirmed the conviction. Mallari appealed to the Supreme Court, raising several arguments, including the legality of the arrest and search, and the prosecution's failure to prove he lacked a license for the firearm.

The Issue: Was the Search and Seizure Valid?

Mallari argued that the officers did not have the warrant of arrest in their possession at the time of his arrest, making the arrest and subsequent search unlawful. He contended that any evidence obtained should therefore be inadmissible.

The Supreme Court disagreed. The Court found that a standing warrant of arrest did exist for Mallari in Criminal Case No. 471. The arresting officers testified that they knew of the warrant but did not bring it because they were in a hurry, fearing Mallari might escape.

The Court cited Section 8, Rule 113 of the Rules of Court, which states that when making an arrest by virtue of a warrant, the officer need not have the warrant in his possession at the time of the arrest. The warrant must simply be shown to the person arrested as soon as practicable if he so requires.

Because the arrest was lawful, the search and seizure made incidental to it were also valid. The Court noted that police officers who discover a crime being committed while performing their duties are not precluded from apprehending the guilty party and taking the corpus delicti.

The Fatal Flaw: No Proof of Lack of License

While the arrest and search were valid, the prosecution's case still failed. The Supreme Court emphasized that in crimes involving illegal possession of firearms, the prosecution must prove two elements:

1. The existence of the subject firearm
2. The fact that the accused who owned or possessed it does not have the corresponding license or permit

The second element is a negative fact that constitutes an essential ingredient of the offense. The prosecution must not only allege it but also prove it beyond reasonable doubt.

In this case, the prosecution presented no evidence—such as a certification from the Philippine National Police Firearms and Explosives Unit—that Mallari was not a licensee of the firearm. The Office of the Solicitor General argued that because the firearm was a homemade "paltik," it was illegal per se and could not have been licensed, so proof of lack of license was unnecessary.

The Supreme Court rejected this argument, citing its earlier ruling in People v. Ramos (222 SCRA 557). The Court held that the fact that a firearm is a paltik does not automatically prove it is unlicensed. The prosecution must still present evidence of the accused's lack of license.

The Court distinguished this case from People v. Mesal (244 SCRA 166), where the prosecution had presented testimony from a military supply officer that the M-14 rifle involved was a weapon only military personnel could possess. No such evidence existed in Mallari's case.

The Ruling

The Supreme Court granted the petition, reversed the conviction, and acquitted Mallari for insufficiency of evidence. The Court ordered his immediate release unless there were other legal grounds for his continued detention.

Practical Takeaways

• Prosecutors must prove lack of license. In illegal possession of firearms cases, the prosecution cannot assume that a homemade or unregistered firearm is unlicensed. It must present evidence, such as a certification from the PNP Firearms and Explosives Unit, to prove the accused had no license.

• A valid warrant need not be physically present during arrest. Police officers may arrest a person without carrying the warrant, as long as a valid warrant exists and is shown to the arrested person as soon as practicable.

• Search incidental to a lawful arrest is valid. When an arrest is lawful—whether by warrant or under the rules on warrantless arrest—a search of the person and the immediate area is permitted without a separate search warrant.

• Evidence obtained from an unlawful search is inadmissible. The exclusionary rule applies to evidence seized without a valid warrant or without a lawful arrest. This is why the legality of the arrest and search matters.

• The presumption of regularity is rebuttable. Courts presume police officers regularly performed their duties, but this presumption can be overcome by evidence of irregularity or improper motive.
