Security Guard Accountability: The Importance of Evidence in Termination Cases

The loss of a company-issued firearm is a serious matter for any security agency. But when a security guard is dismissed over such a loss, what level of proof must the employer present? In DI Security and General Services, Inc. v. National Labor Relations Commission (G.R. No. 124134, November 20, 1996), the Supreme Court settled this question by reaffirming that employers need only present substantial evidence—not proof beyond reasonable doubt—to justify a dismissal.

The Facts of the Case

Danilo T. Santos worked as a security guard for DI Security and General Services, Inc. from November 1986 until August 1990. On the night of July 5, 1990, he was assigned to a shift at Filsyn Corporation in Sta. Rosa, Laguna. Following standard operating procedure, he received a Squires Bingham caliber.38 revolver from the guard he was relieving.

The next morning, around 6 a.m., Santos was at his post near the security office. After asking permission to eat breakfast, he went inside the office. A fellow guard, William Layto, later testified that when Santos entered the office, the revolver was in his holster—but when Santos came out, the holster was empty.

Santos reported for work for several more days, but on July 12, 1990, he was summoned for investigation regarding the missing firearm. He claimed he had turned it over to Sergeant-in-Charge Arminio Dizon, but Dizon denied this. Another guard, Estrellita Lopez, who was inside the security office that morning, also testified she saw no such turnover. The firearm was never recovered.

On August 1990, Santos was served a notice of termination for dishonesty under the agency's Code of Employee Discipline. He filed a complaint for illegal dismissal.

The Issue Before the Court

The central question was whether the National Labor Relations Commission (NLRC) committed grave abuse of discretion when it reversed the labor arbiter's ruling and ordered Santos's reinstatement with backwages.

The NLRC had reasoned that Lopez's testimony "does not rule out the possibility" that Santos turned over the gun to Dizon. The Supreme Court found this reasoning flawed.

The Ruling: Substantial Evidence, Not Proof Beyond Reasonable Doubt

The Supreme Court granted the petition and reinstated the labor arbiter's decision dismissing Santos's complaint. The Court held that the NLRC gravely abused its discretion by applying the wrong quantum of evidence.

The Court cited Rule 133, Section 5 of the Revised Rules of Court, which defines substantial evidence as "that amount of relevant evidence which a reasonable mind might accept as adequate to justify a conclusion." This is the standard for cases before administrative or quasi-judicial bodies like the NLRC—not proof beyond reasonable doubt, which applies in criminal cases.

In this case, the agency presented substantial evidence: Santos admitted receiving the firearm; no turnover was recorded; SIC Dizon denied receiving it; and Lopez's testimony contradicted Santos's claim. Against this, Santos offered only the possibility that he might have returned the gun—which the Court said was not enough.

The Court emphasized that while the law protects labor, "never should the scales be so tilted if the result would be injustice to the employer." It also recognized management prerogatives, so long as they are exercised in good faith.

Practical Takeaways

• Employers in dismissal cases must prove just cause by substantial evidence—relevant evidence that a reasonable mind would accept as adequate. They do not need proof beyond reasonable doubt.
• An employee's bare denial or speculation is not enough to defeat an employer's substantial evidence. The employee must present countervailing evidence to support their defense.
• Loss of a company-issued firearm is a grave matter for security agencies. If the guard cannot account for it and the employer presents credible evidence of the loss, dismissal for dishonesty may be justified.
• The NLRC cannot substitute its own speculation for the factual findings of the labor arbiter when those findings are supported by substantial evidence.
• Documentation matters. Employers should maintain clear records of firearm issuance and turnover, as these will be crucial evidence in any dispute.
