Can an accused be acquitted even if police officers actually recovered an unlicensed firearm and a grenade from his home? Yes. In a recent decision, the Supreme Court reminded law enforcement authorities that obtaining a search warrant is not enough. The warrant itself must comply with the Constitution and the Rules of Court.
In People of the Philippines v. Ernesto Lavarias y Bolinas, G.R. No. 273582, June 9, 2026, the Supreme Court acquitted a man convicted of illegal possession of firearms, ammunition, and explosives after finding that the search warrant used against him was invalid.
The ruling highlights an important protection in Philippine criminal law: evidence obtained through an illegal search cannot be used to convict an accused.
The Case: A Firearm and Grenade Found During a Police Search
On June 30, 2017, police officers searched Ernesto Lavarias' residence in Dagupan City, Pangasinan. During the search, officers reportedly discovered a fragmentation grenade, a .38 caliber revolver, and three live ammunition rounds inside a handbag.
The police conducted an inventory, photographed the seized items, and obtained certifications showing that Lavarias had no license to possess firearms or explosives.
The Regional Trial Court convicted him of illegal possession of firearms and explosives, imposing separate prison sentences, including reclusion perpetua for the explosives charge. The Court of Appeals affirmed his conviction.
However, Lavarias questioned the validity of the search warrant, pointing out that it had been issued by the Regional Trial Court of Burgos, Pangasinan, even though the search was conducted in Dagupan City.
When the case reached the Supreme Court, this issue proved decisive.
Can a Court Issue a Search Warrant for a Place Outside Its Territorial Jurisdiction?
Yes, but only under specific circumstances.
Under Rule 126, Section 2 of the Rules of Court, an application for a search warrant should generally be filed before a court having territorial jurisdiction over the crime.
An application may also be filed before another court within the judicial region where the crime was committed or where the warrant will be enforced, provided there are compelling reasons stated in the application.
The Supreme Court emphasized that these compelling reasons cannot be based on mere assumptions or unsupported allegations. Police officers must present sufficient facts explaining why they could not reasonably apply before the court ordinarily having territorial jurisdiction.
Why Did the Supreme Court Declare the Search Warrant Invalid?
In Lavarias' case, the police claimed that they applied for the search warrant in Burgos instead of Dagupan City because the accused allegedly had connections with personnel of the Dagupan courts.
According to the police, filing the application in Dagupan might compromise the secrecy of their operation. However, the problem was that the police presented no sufficient evidence supporting this supposed risk of information leakage.
The Supreme Court found that the allegation rested merely on a police officer's assertion. Citing People v. Alagaban, the Court explained that when police officers apply for a search warrant before a court outside the ordinary territorial venue, the judge must determine whether the stated compelling reasons have an adequate factual basis.
A general claim that information might leak is insufficient without particular facts supporting that concern. Because the application lacked sufficient justification for filing before the Burgos court, the Supreme Court declared the search warrant null and void.
Why Did an Invalid Search Warrant Result in Acquittal?
The answer lies in the constitutional protection against unreasonable searches and seizures.
Under Article III, Section 2 of the 1987 Constitution, every person has the right to be secure against unreasonable searches of their person, home, papers, and belongings.
When evidence is obtained through an unlawful search, Article III, Section 3(2) prohibits its admission for any purpose in any proceeding. This is commonly known as the exclusionary rule, closely associated with the doctrine of the fruit of the poisonous tree.
In this case, the firearm, ammunition, and grenade were recovered through a search conducted under an invalid warrant. Consequently, these items could not be admitted as evidence against Lavarias. Without the seized items, the prosecution could no longer establish the corpus delicti, or the essential fact that the charged crimes had been committed.
The Supreme Court therefore reversed the convictions and ordered Lavarias' acquittal.
What Does This Ruling Mean for Criminal Cases?
The decision demonstrates that police officers must comply with constitutional safeguards not only when implementing search warrants but also when applying for them.
A search warrant issued by a court outside the ordinary territorial venue is not automatically invalid. However, the compelling reasons justifying that choice of court must be supported by sufficient facts.
More importantly, the discovery of allegedly illegal items does not cure an unconstitutional search. Even where the prosecution claims to have recovered firearms, dangerous drugs, or explosives, the evidence may be excluded if obtained in violation of constitutional rights.
This ruling is particularly relevant to criminal defense cases involving illegal possession of firearms, explosives, and other offenses where the prosecution relies heavily on evidence recovered through search warrants.
