In the landmark case of People vs. Julian Castillo y Lumayro, the Supreme Court clarified the application of Republic Act No. 8294, which amended Presidential Decree No. 1866 regarding illegal possession of firearms. The Court ruled that using an unlicensed firearm in the commission of murder or homicide should be treated as a special aggravating circumstance, rather than a separate offense. This means that an accused can only be convicted and penalized for the primary crime of murder or homicide, with the illegal possession of firearm serving to increase the severity of the punishment. This decision significantly alters how such cases are prosecuted and adjudicated, ensuring that only one penalty is imposed for what is now considered a single, aggravated offense.

When a Single Bullet Redefines Double Jeopardy: Castillo’s Case

The case revolves around Julian Castillo, who was initially charged with both murder and illegal possession of firearms following the death of Rogelio Abawag. Witnesses testified that Castillo pursued and shot Abawag at a construction site. Apprehended while attempting to flee, Castillo was found in possession of an unlicensed .38 caliber revolver. The trial court convicted him of homicide and illegal possession of a firearm aggravated by homicide, sentencing him to imprisonment and death, respectively. Castillo appealed, questioning his conviction for illegal possession, arguing the prosecution failed to prove he lacked a license for the firearm.

The Supreme Court, in its review, addressed the core issue of whether Castillo could be convicted and separately penalized for both homicide and illegal possession of a firearm. Citing Republic Act No. 8294, the Court emphasized the law’s provision that the use of an unlicensed firearm in murder or homicide constitutes a special aggravating circumstance. The Court stated:

“With the passage of Republic Act No. 8294 on June 6, 1997, the use of an unlicensed firearm in murder or homicide is now considered, not as a separate crime, but merely a special aggravating circumstance.”

This interpretation meant that Castillo should have been charged with a single crime: homicide aggravated by the use of an unlicensed firearm. The Court found that the trial court erred in convicting Castillo of two separate offenses and imposing separate penalties. This legal adjustment had significant implications for Castillo’s sentence.

Furthermore, the Supreme Court delved into the prosecution’s failure to provide sufficient evidence regarding Castillo’s lack of a firearm license. The Court reiterated that in cases of illegal possession, the prosecution bears the burden of proving two essential elements: the existence of the firearm and the absence of a license or permit for its possession. The Court underscored this point, stating:

“Two (2) requisites are necessary to establish illegal possession of firearms: first, the existence of the subject firearm, and second, the fact that the accused who owned or possessed the gun did not have the corresponding license or permit to carry it outside his residence. The onus probandi of establishing these elements as alleged in the Information lies with the prosecution.”

While the prosecution successfully proved the existence of the firearm, it failed to present concrete evidence demonstrating that Castillo did not possess a license. The Court noted that the prosecution could have presented testimony or certification from the PNP Firearms and Explosives Unit to establish this negative fact. Absent such evidence, the Court deemed the prosecution’s case insufficient to support a conviction for illegal possession.

The Court also addressed Castillo’s admission that he lacked a license for the firearm. While Castillo admitted that he had no license for the gun recovered from his possession, his admission will not relieve the prosecution of its duty to establish beyond reasonable doubt the appellant’s lack of license or permit to possess the gun. Citing People vs. Solayao, the court stated:

“x x x (b)y its very nature, an ‘admission is the mere acknowledgement of a fact or of circumstances from which guilt may be inferred, tending to incriminate the speaker, but not sufficient of itself to establish his guilt.’ In other words, it is a ‘statement by defendant of fact or facts pertinent to issues pending, in connection with proof of other facts or circumstances, to prove guilt, but which is, of itself, insufficient to authorize conviction.’ From the above principles, this Court can infer that an admission in criminal cases is insufficient to prove beyond doubt the commission of the crime charged.”

The Court emphasized that this extrajudicial admission, made without the benefit of counsel, did not relieve the prosecution of its burden to prove the lack of a license beyond a reasonable doubt. Due to the lack of sufficient evidence regarding the absence of a license, the Supreme Court ultimately acquitted Castillo of the charge of illegal possession of a firearm.

Considering these factors, the Supreme Court modified the trial court’s decision. Castillo was found guilty solely of homicide, and his sentence was adjusted accordingly. The Court then stated:

“Appellant Julian Castillo y Lumayro is found guilty of Homicide. He is sentenced to imprisonment of from nine (9) years and four (4) months of prision mayor as minimum to sixteen (16) years, five (5) months and nine (9) days of reclusion temporal as maximum.”
