DE JABASA, ET AL., PACIENCIA CAMA, and CONSOLACION AMADOR, petitioners, vs. THE WORKMEN’S COMPENSATION COMMISSION and THE CITY OF MANILA, REPUBLIC OF THE PHILIPPINES (BUREAU OF PUBLIC SCHOOLS), REPUBLIC OF THE PHILIPPINES (COURT OF AGRARIAN RELATIONS), ATLAS CONSOLIDATED MINING AND DEVELOPMENT CORPORATION, and FAR EASTERN UNIVERSITY, respondents.

FACTS

These ten consolidated cases involve claims for disability compensation under the Workmen’s Compensation Act. In each instance, the petitioners, who were public school teachers, government employees, or private sector workers, filed claims for illnesses incurred or aggravated during their employment. The respective referees of the Workmen’s Compensation Commission initially awarded benefits, finding the illnesses compensable and often citing the statutory presumption of compensability.
However, the Workmen’s Compensation Commission, on appeal by the employers, uniformly reversed these awards. The Commission’s reversals were based on various grounds, including that the illness was “inactive” and thus not disabling, that the claimant failed to submit the “best evidence” like an X-ray result, that the ailments were not permanently disabling, or that the separation from service was due to optional retirement and not disability. The Commission essentially required the claimants to positively disprove these employer-initiated defenses.

ISSUE

The central issue is whether the Workmen’s Compensation Commission erred in reversing the referees’ awards by disregarding the mandatory legal presumption of compensability under Section 44 of the Workmen’s Compensation Act and by improperly shifting the burden of proof to the claimants.

RULING

The Supreme Court reversed the decisions of the Workmen’s Compensation Commission and reinstated the referees’ awards, with modifications for attorney’s fees. The Court’s legal logic is anchored on the primacy of the presumption of compensability. Under Section 44 of the Act, once an illness supervenes during employment, it is presumed that the claim is compensable. The burden to overthrow this presumption lies with the employer, who must present substantial evidence that the illness did not arise from or was not aggravated by the employment.
The Court held that the Commission committed a grave error by ignoring this presumption and, instead, placing the burden on the claimants to prove the causal link. The employers’ defenses—such as the claim that an illness was “inactive,” that retirement was “optional,” or that medical evidence was not the “best”—were deemed non-conclusive and insufficient to constitute the “substantial evidence” required to rebut the statutory presumption. The Court reiterated that the Act is a social legislation designed to aid the worker, and its provisions must be liberally construed in their favor. The fact of illness during employment, coupled with the resulting disability or need for medical treatment, invokes the presumption. Since the employers failed to present compelling evidence to defeat this presumption, the awards granted by the referees were legally sound. The Court further awarded attorney’s fees as provided by the Act and its rules.
