GSIS vs. Court of Appeals

For a sickness not listed as an occupational disease under P.D. No. 626 to be compensable, the claimant must prove by substantial evidence that the risk of contracting the disease was increased by the claimant's working conditions; mere allegations, hearsay, or sweeping conclusions do not constitute substantial evidence. The Court held that the presumption of compensability has been abandoned under P.D. No. 626, and compassion for victims of non-compensable diseases cannot override the need to protect the integrity of the State Insurance Fund.

Jaime Liwanag, a Senior Superintendent of the Philippine National Police (PNP) with 17 years of service, died on September 14, 1994, of Upper GI Bleeding, Cirrhosis Secondary to Hepatitis B, and Hepatocellular Carcinoma. His widow, Zenaida Liwanag, filed a claim for compensation benefits with the Government Service Insurance System (GSIS).

• Decedent's Illness and Death: P/Sr. Supt. Jaime Liwanag was admitted to the Medical Center of Manila on August 28, 1994, and died on September 14, 1994. His cause of death was certified as Upper GI Bleeding, Cirrhosis Secondary to Hepatitis B, and Hepatocellular Carcinoma.
• Denial of Claim: Zenaida Liwanag filed a claim with the GSIS. The GSIS denied the claim, and the ECC affirmed, ruling that Hepatitis B is not an occupational disease and that the claimant failed to prove that the risk of contracting the disease was increased by the decedent's employment. The ECC cited the Merck Manual to show that the disease strikes anyone regardless of employment.
• PNP Board Reports: To support her appeal to the Court of Appeals, the claimant submitted an Investigation Report and a Line of Duty (LOD) Board Report from the PNP. The Investigation Report concluded it was "highly believable" that Liwanag acquired his illness in the course of employment because some personnel in his office tested positive for Hepatitis B. The LOD Board Report featured testimony from P/SInsp. Ritualo opining that the decedent likely contracted the virus at headquarters, which he claimed was "endemic" for Hepatitis B, though no specific mode of transmission was established. The LOD Board also relied on a Ministry of National Defense Order presuming line-of-duty death for active military personnel.
• Procedural Irregularity: Police Chief Inspector Gonzalodo, who authored the Investigation Report recommending the grant of benefits, also sat as a member and recorder of the LOD Board that subsequently ruled on the matter.

• Petitioner GSIS argued that Hepatitis B is not an occupational disease and the claimant failed to prove increased risk by working conditions.
• Petitioner contended the PNP reports were inadmissible hearsay because they relied on mere association with infected colleagues without medical proof of parenteral transmission.
• Petitioner asserted that no substantial evidence pointed to a reasonable connection between the ailment and employment, and that undue compassion for non-compensable diseases endangers the State Insurance Fund.

• Respondent Liwanag relied on the PNP Board reports to establish a causal relation between the illness and employment.
• Respondent argued that the requirement of proof of causal relation admits of exceptions and must yield to higher interests of justice.
• Respondent advocated for a liberal interpretation of social legislation, citing jurisprudence relaxing procedural requirements.

• Procedural Issues: N/A
• Substantive Issues:
  • Whether the Court of Appeals erred in finding that the claimant presented substantial evidence to prove that the risk of contracting Hepatitis B was increased by the decedent's working conditions.
  • Whether the PNP Board reports constitute substantial evidence of compensability under P.D. No. 626.

• Procedural: N/A
• Substantive: The Court held that the CA erred. P.D. No. 626 abandoned the presumption of compensability; thus, for unlisted diseases, the claimant must prove by substantial evidence that working conditions increased the risk of contracting the illness. The PNP reports failed to meet this standard because they contained sweeping conclusions and hearsay without showing how the decedent contracted the disease from co-workers. The LOD Board relied on a military order presuming line-of-duty death, which applies to military benefits and is distinct from the compensability standard under P.D. No. 626. The Court also observed that the LOD Board proceedings violated due process because Police Chief Inspector Gonzalodo, who had pre-judged the matter by recommending benefits in the Investigation Report, sat as a member and recorder of the Board. Courts must respect the findings of quasi-judicial agencies like the ECC on technical matters absent grave abuse of discretion.

• Substantial Evidence in Administrative Proceedings — Defined as more than a mere scintilla, it means such relevant evidence as a reasonable mind might accept as adequate to support a conclusion. Mere uncorroborated hearsay or rumor does not constitute substantial evidence. The Court applied this to rule that the PNP Board's sweeping conclusions and lay opinions on disease transmission were insufficient to support the compensation claim.
• Compensability of Illness under P.D. 626 — P.D. 626 abandoned the presumption of compensability and the theory of aggravation. For a sickness not listed as an occupational disease to be compensable, the claimant must prove that the risk of contracting the disease was increased by working conditions.
• Protection of the State Insurance Fund — Undue compassion for victims of diseases not covered by law endangers the integrity of the State Insurance Fund, upon which millions of workers rely. The burden of proof rests on the claimant, not the employer or the fund.
• Impartial Tribunal in Administrative Proceedings — One called upon to resolve a dispute may not sit as judge and jury simultaneously. An investigator who pre-judged a matter by recommending benefits should inhibit from the board reviewing the same to ensure due process.

• "Substantial evidence is more than a mere scintilla. It means such relevant evidence as a reasonable mind might accept as adequate to support a conclusion... But this assurance of a desirable flexibility in administrative procedure does not go so far as to justify orders without a basis in evidence having rational probative force."
• "Compassion for the victims of diseases not covered by the law ignores the need to show a greater concern for the trust fund to which the tens of millions of workers and their families look to for compensation whenever covered accidents, diseases and deaths occur."

• Ang Tibay v. Court of Industrial Relations, 69 Phil. 635 — Followed. Established the standard of substantial evidence in administrative proceedings and the requirement of an impartial tribunal.
• Rivera v. Civil Service Commission, 240 SCRA 43 — Followed. Held that a commissioner who participated in a case at the lower level must inhibit from the appellate level to preserve due process.
• Latagan v. Employees' Compensation Commission, 213 SCRA 715 — Followed. Affirmed the abandonment of the presumption of compensability under P.D. 626.
• Raro v. Employees' Compensation Commission, 172 SCRA 845 — Followed. Emphasized the need to protect the State Insurance Fund from undeserving claims.

• Presidential Decree No. 626, as amended — The Employees' Compensation and State Insurance Fund law. Applied to establish that unlisted diseases require proof of increased risk by working conditions, abandoning the old presumption of compensability.
• Section 1(B), Rule III of the Amended Rules on Employees' Compensation — Defines when a sickness or death is compensable. Applied to require proof that the risk of contracting the disease was increased by working conditions if the disease is not listed as occupational.
• Ministry of National Defense Department Order No. 162 (s. 1965) — Presumes a military member who died in active service died in the line of duty. Distinguished; the Court held this presumption applies to military line-of-duty benefits, not to compensability under P.D. 626.
