The Supreme Court held that facts discovered during surveillance operations, based on information provided by complainants, constitute personal knowledge sufficient for issuing a search warrant. This ruling emphasizes that authorities can rely on their investigative findings to establish probable cause, even if they initially acted on tips from third parties. This decision clarifies the threshold for obtaining search warrants in cases involving illegal trading and underfilling of liquefied petroleum gas (LPG) products, impacting businesses and consumers by ensuring that law enforcement can effectively investigate and prosecute such violations.

Can Surveillance Operations Validate a Search Warrant in Cases of Illegal LPG Trading?

Petron LPG Dealers Association and Total Gaz LPG Dealers Association filed a complaint against Nena C. Ang, Alison C. Sy, Nelson C. Ang, Renato C. Ang, and National Petroleum Corporation (Nation Gas), alleging illegal trading and underfilling of LPG products, violating Batas Pambansa Blg. 33 (BP 33), as amended. The NBI-IRO, led by Agent Marvin de Jemil, conducted surveillance and a test-buy operation based on this complaint. During the surveillance, De Jemil observed a Barba Gas delivery truck entering Nation Gas’s refilling plant and later purchased a refilled Starflame LPG cylinder from Barba Gas. Based on these findings, the NBI filed applications for search warrants, which the trial court initially granted but later quashed, arguing that De Jemil lacked personal knowledge and that the certifications presented were hearsay. The Court of Appeals affirmed the trial court’s decision, leading to the Supreme Court review.

The central issue before the Supreme Court was whether the NBI agents had sufficient personal knowledge to establish probable cause for the issuance of the search warrants. Petitioners argued that the surveillance and test-buy operations provided De Jemil and Antonio with personal knowledge of the illegal activities. Respondents countered that the agents lacked personal knowledge because they did not witness the actual refilling process and relied on unauthenticated certifications. The resolution of this issue hinged on interpreting the requirements for establishing probable cause and the admissibility of evidence gathered during surveillance operations.

The Supreme Court granted the petition, reversing the Court of Appeals’ decision and upholding the validity of the search warrants. The Court emphasized that the requisites for the issuance of a search warrant are well-established: probable cause, personal determination by the judge, examination of the complainant and witnesses under oath, testimony based on personal knowledge, and specific description of the place to be searched and items to be seized.

Probable cause, the Court noted, exists when facts and circumstances would lead a reasonably prudent person to believe that an offense has been committed and that evidence related to the offense is located at the place to be searched.

“Probable cause for a search warrant is defined as such facts and circumstances which would lead a reasonably discreet and prudent man to believe that an offense has been committed and that the objects sought in connection with the offense are in the place sought to be searched. A finding of probable cause needs only to rest on evidence showing that, more likely than not, a crime has been committed and that it was committed by the accused.”

Building on this principle, the Court found that the evidence presented by the NBI, including the certifications and results of the test-buy, was sufficient to establish probable cause. The Court referenced the case of Ty v. NBI Supervising Agent De Jemil, which addressed similar issues regarding the illegal refilling of LPG cylinders. In Ty, the Court outlined the types of evidence that could be used to prove such violations, including surveillance operations, test-buys, and written certifications from LPG companies. These certifications detail authorized refillers, and written reports from tests conducted on the LPG cylinders. The Supreme Court considered that these factors showed probable cause.

The Court pointed out that BP 33, as amended, prohibits the refilling and underfilling of branded LPG cylinders by unauthorized refillers. This prohibition stems from the principle that the LPG brand owner retains ownership of the cylinders, even when they are in the possession of customers. Therefore, the Court held that the NBI’s surveillance and test-buy operations, coupled with the written certifications, provided a sufficient basis for concluding that Nation Gas was engaged in illegal refilling activities. The Supreme Court emphasized the significance of the test-buy operation, calling it a clear violation of Sec. 2(a), in relation to Sees. 3(c) and 4 of BP 33, as amended.

Moreover, the Court addressed the issue of personal knowledge, stating that the facts discovered during the NBI’s surveillance constituted personal knowledge sufficient to support the issuance of a search warrant. It cited Cupcupin v. People, where the Court held that information obtained through surveillance and confidential sources could provide the basis for personal knowledge. The Court rejected the argument that the NBI agents needed to witness the actual refilling process to establish probable cause, as the totality of the circumstances supported a reasonable belief that illegal activities were taking place.

To fully appreciate the interplay of factors that constitute a violation of BP 33, as amended, consider the following:

Element	Description
Illegal Refilling	Refilling branded LPG cylinders without written authorization from the brand owner.
Underfilling	Selling or possessing underfilled LPG cylinders for distribution or sale beyond authorized limits.
Evidence	Surveillance, test-buys, certifications from LPG companies, and inspection reports.

The Court noted that the findings in Ty regarding preliminary investigation proceedings were applicable to the search warrant applications in this case, as both require the same degree of proof—probable cause. The Court emphasized the importance of deterring unscrupulous business practices in the LPG industry and protecting the rights of brand owners. Thus, the Supreme Court held that the surveillance and test-buy operations, in conjunction with the certifications, provided the agents with personal knowledge of illegal activities.
