G.R. No. 190410 April 10, 2019
QUIRICO D. ANIÑON, Petitioner, vs. GOVERNMENT SERVICE INSURANCE SYSTEM, Respondent.

FACTS

Petitioner Quirico D. Aniñon rendered intermittent government service from 1969 to 1982. He resigned in 1989, having only 12 years of service, and received a refund of his retirement premiums under the then-prevailing law. He was reinstated in 1996 and served until his compulsory retirement in 2008 under Republic Act No. 8291 (GSIS Act of 1997). This new law allowed the inclusion of previous service periods for reinstated employees, provided no benefits were previously awarded for those years. The GSIS, through Policy and Procedural Guidelines (PPG) No. 183-06, allowed such reinstated employees to have their past service credited if they refunded previously received benefits within 30 days from the guideline’s publication.
Aniñon sought to refund his earlier received premiums to include his pre-1989 service in computing his 15-year eligibility for retirement benefits under R.A. No. 8291. The GSIS Board of Trustees denied his request, ruling he failed to comply with the 30-day refund window under PPG No. 183-06. The Court of Appeals affirmed this denial.

ISSUE

Whether the GSIS acted with grave abuse of discretion in denying Aniñon’s request to refund his prior premiums to credit his past service for retirement eligibility under R.A. No. 8291.

RULING

The Supreme Court granted the petition, reversing the CA and GSIS rulings. The Court emphasized that retirement laws are social legislation designed to provide for the retiree’s financial security and must be liberally construed in their favor. The GSIS’s imposition of a strict 30-day refund period from the publication of its internal guideline (PPG No. 183-06) was an unreasonable restriction that contravened this liberality.
The legal logic is anchored on the principle that administrative issuances, like PPG No. 183-06, must not amend or restrict the substantive law they seek to implement. R.A. No. 8291 itself contains no such prohibitive deadline for refunding prior benefits to reinstate service credit. By creating an inflexible cutoff, the GSIS effectively barred a legitimate class of retirees, like Aniñon, from availing themselves of a benefit clearly intended by the statute. This constituted a grave abuse of discretion. The Court held that Aniñon’s offer to refund the premiums, made in good faith upon learning of the possibility, should be accepted to allow the full crediting of his government service, thereby qualifying him for retirement benefits under the law’s benevolent intent.
