G.R. No. L-42323. April 30, 1976.
Eufronio Ruelan, claimant, vs. Republic of the Philippines (Bureau of Public Schools), and Workmen’s Compensation Commission, respondents.

FACTS

Petitioner Eufronio Ruelan, a public school teacher for 36 years, was forced to optionally retire in 1973 due to pulmonary tuberculosis and impaired eyesight (cataract), illnesses he began experiencing in 1965. The Acting Referee of the Workmen’s Compensation Commission Regional Office awarded him disability compensation and medical reimbursement, finding his illnesses work-connected and aggravated. The respondent employer did not appeal this award, rendering it final as to the issue of compensability.
Dissatisfied with the compensation amount, petitioner appealed solely to increase his disability award to the statutory maximum of P6,000.00. The respondent Commission, however, did not confine its review to this monetary issue. Instead, it reversed the entire award and absolved the employer from liability. The Commission ruled it was “unreasonable” to trace the illnesses to his employment because the medical examinations confirming them were conducted nearly a year after his retirement, speculating the ailments could have been contracted during that intervening period.

ISSUE

Whether the respondent Workmen’s Compensation Commission acted with grave abuse of discretion in setting aside the final award on compensability and absolving the employer from liability.

RULING

Yes. The Supreme Court reversed the Commission’s decision, finding it acted arbitrarily and with grave abuse of discretion. The legal logic is clear: when the employer did not appeal the Referee’s award declaring the illnesses compensable, that finding became final and executory. The only issue properly before the Commission on review was the claimant’s appeal regarding the amount of compensation. The Commission exceeded its authority by reopening and overturning the settled question of compensability, a matter no longer in issue. Its action disregarded fundamental principles, including the finality of unappealed judgments and the statutory presumption of compensability for illnesses supervening during employment.
The Court further found the Commission’s reasoning—that the post-retirement medical exams severed the link to employment—capricious, as it ignored uncontroverted facts: the illnesses manifested during employment, incapacitated the claimant before retirement, and were undisputed by the employer. On the claimant’s appeal for higher compensation, the Court found substantial evidence, including a 50% visual disability rating and a period of temporary total disability, warranting an increase to the maximum P6,000.00. The award was reinstated and modified accordingly.
