G.R. No. 125982 - Government Service Insurance System vs. Commission on Audit and Mariano C. Gaborne

In November 1936, Congress enacted Commonwealth Act No. 186, establishing the Government Service Insurance System (GSIS) to provide insurance coverage and retirement benefits to government officials and employees, supplanting prior pension systems.
Section 4 of Commonwealth Act No. 186 provided compulsory membership to "all officers and enlisted men of the Regular Force, Philippine Army."
This act underwent several amendments, expanding coverage and benefits.

On December 2, 1986, President Corazon C. Aquino, exercising legislative powers, issued Executive Order No. 79.
Section 1(c) of EO No. 79 states that reserve officers who have satisfactorily rendered ten (10) years of continuous active commissioned military service shall not be reverted to inactive status except upon their own request or for cause, until mandatory retirement (30 years of service or age 56, whichever is later, but not beyond age 60).

On November 16, 1987, Brig. General Arturo T. Asuncion died in a helicopter crash while in line of duty.
On December 11, 1987, the GSIS board of trustees passed Resolution No. 566, approving compulsory insurance coverage of AFP reserve officers falling under EO No. 79 provisions.

The heirs of Brig. Gen. Asuncion filed a claim with GSIS for death benefits.
On January 12, 1987 (probably a typographical error, intended 1988), GSIS Deputy General Counsel Meynardo A. Tiro opined that reserve officers with ten (10) years continuous service under EO No. 79 are entitled to benefits equal to regular AFP officers.
On September 4, 1990, GSIS Legal Services Vice President Melanio D. Fabia opined that compulsory coverage for reserve officers took effect on December 23, 1986, following EO No. 79's Official Gazette publication.
Based on these opinions, on January 4, 1991, GSIS Quezon City Branch paid death benefits to the heirs.

Auditor Mariano C. Gaborne, during audit, disallowed the payment, stating that at the time of General Asuncion's death, he was not a GSIS member because EO No. 79 became effective only after GSIS board approval on December 11, 1987 (after his death).
The GSIS Quezon City Branch Manager appealed the disallowance to the Commission on Audit (COA).
On January 24, 1995, COA en banc denied the appeal, affirming the auditor's disallowance.

GSIS filed a petition for certiorari before the Supreme Court, challenging the COA decision.
The Court found that EO No. 79, as an executive order with force of law, became effective 15 days after its December 22, 1986 publication in the Official Gazette, i.e., effective January 7, 1987.
Since General Asuncion died on November 16, 1987, he was a compulsory GSIS member at his time of death due to EO No. 79.
The optional insurance policy that lapsed in April 1984 was distinct from compulsory GSIS coverage and did not affect entitlement.

Whether the heirs of Brig. Gen. Arturo T. Asuncion are entitled to death benefits from GSIS despite disallowance by the auditor and COA on grounds of non-membership at the time of death.

When did Executive Order No. 79, which grants compulsory GSIS membership to qualified AFP reserve officers, become effective?

Whether the lapsed optional insurance policy affects the entitlement of death benefits under compulsory GSIS coverage.
