Gatus vs. Social Security System

A claim for employees' compensation for an illness not listed as occupational requires substantial evidence that the risk of contracting the disease was increased by working conditions, and factual findings of administrative agencies affirmed by the appellate court cannot be reviewed in a petition for review on certiorari under Rule 45.

Alexander B. Gatus worked at Central Azucarera de Tarlac from January 1, 1972, optionally retiring on January 31, 2002, after 30 years of service as a Tender at the Distillery Cooling Tower. In 1995, he suffered chest pains and was diagnosed with Coronary Artery Disease (CAD): Triple Vessel and Unstable Angina, with a 10-year history of hypertension and documented smoking. SSS initially granted partial disability benefits but later sought to recover them after an audit revealed his CAD was attributed to chronic smoking and deemed not work-related.

• Employment and Retirement: Gatus worked at Central Azucarera de Tarlac starting January 1, 1972, optionally retiring on January 31, 2002, at age 62 after 30 years of service.
• Diagnosis and Initial Grant of Benefits: In August 1995, Gatus was confined and diagnosed with Coronary Artery Disease (CAD): Triple Vessel and Unstable Angina. Medical records indicated he was hypertensive for 10 years and a smoker. SSS initially granted him Permanent Partial Disability benefits.
• SSS Audit and Reversal: In 2003, an SSS audit concluded that Gatus's CAD was not work-related because it was attributed to chronic smoking. SSS notified him of the need to recover the EC benefits and denied his motion for reconsideration.
• ECC Appeal: Gatus elevated the matter to the ECC, which denied the appeal on December 10, 2004. The ECC ruled that while CAD is listed as an occupational disease, Gatus failed to prove the qualifying circumstances, specifically that his employment increased the risk of contracting the disease, noting his documented chronic smoking as a primary risk factor.

• Increased Risk Theory: Petitioner contended that he contracted CAD due to 30 years of exposure to harmful fuel smoke emissions, methane gas, and diesel locomotive smoke containing carbon monoxide, carbon dioxide, sulfur, and nitrogen oxides at his workplace.
• Lack of Proof of Smoking: Petitioner insisted that the allegation of his cigarette smoking was not proven and that the ECC presented no document signed by a competent medical authority to back the claim.
• Due Process and Jurisdiction: Petitioner claimed the appellate court's decision was against existing jurisprudence on the increased risk theory and violated due process, asserting that the ECC records were not elevated to the CA and his evidence was ignored.

• Lack of Substantial Evidence: Respondent argued that Gatus failed to show substantial evidence that his disease was work-related or that his employment had a causal relation to his heart ailment.
• Smoking as Cause: Respondent maintained that medical findings revealed he was a chain smoker, a lifestyle factor that contributed to his heart ailment, damaging blood vessels and causing atherosclerosis.
• Mere Allegations of Exposure: Respondent countered that Gatus's claims of harmful emissions were bare allegations not backed by scientific or factual evidence, failing to show which specific emissions were present and how much exposure contributed to his illness.

• Compensability: Whether the Court of Appeals committed grave abuse of discretion in affirming the ECC's finding that petitioner's CAD is not compensable under P.D. 626 for lack of substantial evidence of work-connection.
• Factual Review: Whether the factual finding of petitioner's chronic smoking can be reviewed by the Supreme Court in a petition for review on certiorari.

• Compensability: The petition was denied, the appellate court having correctly affirmed the ECC. Petitioner failed to discharge the burden of proving by substantial evidence that the risk of contracting his disease was increased by his working conditions. His mere contention of exposure to smoke emissions, without medical or scientific proof linking such exposure to his CAD, does not make his disability compensable. He also failed to show the presence of any of the conditions imposed for cardiovascular diseases under Annex "A" of the Amended Rules on Employees' Compensation.
• Factual Review: The factual finding that petitioner was a chronic smoker, as established by the SSS, ECC, and CA, cannot be reviewed in a petition for review on certiorari under Rule 45, which is limited to questions of law. The Supreme Court is not a trier of facts and accords great weight and finality to the factual findings of administrative agencies and quasi-judicial bodies when affirmed by the Court of Appeals.

• Substantial Evidence Rule in Employees' Compensation — The requisite quantum of proof in claims before administrative or quasi-judicial bodies is substantial evidence, or that amount of relevant evidence which a reasonable mind might accept as adequate to justify a conclusion. The claimant must prove a positive proposition; awards of compensation cannot rest on speculations or presumptions.
• Finality of Administrative Findings of Fact — Findings of fact of administrative agencies and quasi-judicial bodies, which have acquired expertise because their jurisdiction is confined to specific matters, are generally accorded not only respect but finality when affirmed by the Court of Appeals.

• "What the law requires is a reasonable work connection, not a direct causal relation."
• "Awards of compensation cannot rest on speculations or presumptions, for the claimant must prove a positive proposition."
• "The policy of extending the applicability of P.D. 626 as many qualified employees as possible should be balanced by the equally vital interest of denying undeserving claims for compensation."

• Ortega v. Social Security Commission, G.R. No. 176150, June 25, 2008 — Followed. Cited for the rule that substantial evidence is the requisite quantum of proof in administrative/quasi-judicial cases, and that the Court accords great weight and finality to the factual findings of administrative agencies and quasi-judicial bodies when affirmed by the CA.
• Sante v. Employees’ Compensation Commission — Followed. Cited for the principle that evidence must be real and substantial, not merely apparent, and that compensation awards cannot rest on speculations or presumptions.
• La Union Cement Workers Union v. National Labor Relations Commission, G.R. No. 174621, January 30, 2009 — Followed. Cited for the doctrine that the Supreme Court is not a trier of facts and pure issues of fact may not be raised in a petition for review under Rule 45.
• Development Bank of the Philippines v. Traders Royal Bank, G.R. No. 171982, August 18, 2010 — Followed. Cited for the distinction between a question of fact and a question of law.

• Section 1, Rule III, Amended Rules on Employees' Compensation — Provides the grounds for compensability: for a sickness to be compensable, it must be the result of an occupational disease listed under Annex "A" with conditions satisfied; otherwise, proof must be shown that the risk of contracting the disease is increased by the working conditions. Applied to deny the claim because the illness was not proven to be increased by working conditions.
• Annex "A", Amended Rules on Employees' Compensation — Lists the conditions for an occupational disease to be compensable and specifically outlines when cardiovascular diseases are considered occupational. Applied to deny the claim because none of the conditions for cardiovascular diseases were proven.
• Section 1, Rule 45, Rules of Court — States that a petition for review on certiorari shall raise only questions of law. Applied to bar the review of the factual finding regarding petitioner's smoking habit.
