G.R. No. 218097 - Government Service Insurance System vs. Daymiel

Apolinario K. Daymiel served as a casual laborer in the Provincial Engineering Office of Zamboanga del Norte beginning August 18, 1969, and later as Accounting Clerk III until his retirement on July 1, 2003.
He applied for retirement benefits with the GSIS, for which an initial computation credited him with 33.65678 years of service, a lump sum of ₱542,325.00, and a monthly pension of ₱9,038.75.

GSIS re-computed his service at 23.85082 years based on Policy and Procedural Guidelines No. 171-03 (PPG No. 171-03, March 24, 2003) and GSIS Board Resolution No. 90 (April 2, 2003), reducing his benefits to a ₱384,295.80 lump sum and ₱5,886.77 monthly pension.
PPG No. 171-03 defined “services” for computation purposes as those with fixed monthly compensation and timely remitted contributions, in contrast to RA 8291’s definition from date of original appointment.

Before the RTC of Dipolog City, Daymiel filed for declaratory relief, mandamus, and damages. The GSIS moved to dismiss for lack of cause and jurisdiction. The RTC initially granted dismissal, then reversed, invalidating PPG No. 171-03/Resolution No. 90 for non-publication, but ultimately dismissed for lack of jurisdiction under Section 30, RA 8291.
On appeal, the CA reversed in February 2014, declared the issuances null and void for lack of publication, and directed recomputation from original appointment. A GSIS motion for reconsideration was denied in April 2015. GSIS filed a Rule 45 petition with the Supreme Court.

Whether the RTC has jurisdiction to entertain Daymiel’s petition for declaratory relief attacking the validity of GSIS administrative issuances.
Whether PPG No. 171-03 and GSIS Resolution No. 90 are valid despite their non-publication.
