G.R. No. L-74727. June 16, 1988.
MELENCIO GIGANTONI y JAVIER, petitioner, vs. PEOPLE OF THE PHILIPPINES and INTERMEDIATE APPELLATE COURT, respondents.

FACTS

Petitioner Melencio Gigantoni, a former PC-CIS agent dismissed for gross misconduct in 1980, was charged with usurpation of authority under Article 177 of the Revised Penal Code. The information alleged that on May 14 and 15, 1981, in Makati, he willfully and falsely represented himself as a bona fide CIS agent to Philippine Air Lines (PAL) officials. Posing as an agent investigating a kidnapping case, he requested and obtained xerox copies of passenger manifests and tickets. PAL officials, becoming suspicious, verified with the PC-CIS and discovered his dismissal. Upon his return the next day, he was confronted, admitted he was no longer with the CIS and was working for a private company, and was subsequently arrested by NBI agents.
The Regional Trial Court convicted Gigantoni, a decision affirmed by the Intermediate Appellate Court with a modified penalty. Gigantoni appealed, contending he could not be guilty because he was allegedly merely suspended and had not been officially notified of his dismissal. He argued the prosecution relied on a mere disputable presumption—that official duty had been regularly performed—to prove he received notice, which was insufficient to overturn the constitutional presumption of innocence.

ISSUE

Did the prosecution prove beyond reasonable doubt that petitioner Gigantoni knowingly and falsely represented himself as a CIS agent, an essential element of the crime of usurpation of authority under Article 177 of the Revised Penal Code?

RULING

No. The Supreme Court reversed the conviction and acquitted Gigantoni. The legal logic centers on the specific elements of the crime charged and the burden of proof in criminal cases. Gigantoni was charged solely with “usurpation of authority” under the first part of Article 177, which requires that the accused “knowingly and falsely” represent himself as a government officer or agent. The Court distinguished this from “usurpation of official functions” under the second part of the same article, which involves performing acts under pretense of official position.
The prosecution’s case failed because it did not present positive, competent evidence proving Gigantoni actually knew he was dismissed at the time of the representation. His admission of receiving a suspension notice was not equivalent to proof of receiving a dismissal notice. The lower courts erroneously applied the disputable presumption that official duty (i.e., the service of the dismissal order) was regularly performed to conclude he was notified. In criminal law, the burden of proving every element of the crime beyond reasonable doubt rests solely on the prosecution. This constitutional standard cannot be satisfied by a mere disputable presumption; it requires direct or credible circumstantial evidence. The prosecution did not discharge this burden regarding the essential element of “knowing” falsity.
Furthermore, the Court noted the Solicitor General’s argument—that suspension or dismissal equally deprives authority—would be relevant if Gigantoni were charged with usurpation of official functions for performing a specific act pertaining to an office. However, he was charged only with the false representation itself. The information he obtained from PAL was not shown to be confidential or given solely by virtue of official function. Thus, the conviction for usurpation of authority could not stand due to the prosecution’s failure to prove a critical element of the crime.
