Case Summary (G.R. No. 185035)

Factual Background

De Castro entered and served in the PAF as a soldier until his retirement on March 2, 2006. On December 22, 2004, he was admitted to the V. Luna General Hospital, AFP Medical Center, due to chest pains. On January 21, 2005, a 2-D echocardiography revealed “dilated left atrium eccentric left ventricular hyperthropy and left ventricular dysfunction,” and his full diagnosis included hypertensive cardiovascular disease, dilated atrium, eccentric left ventricular hypertrophy, left ventricular dysfunction, and an old anterior wall myocardial infarction. A coronary angiogram showed that he had significant simple vessel coronary artery disease (CAD).

On August 15, 2005, he was confined again at the same hospital and was diagnosed with (1) 41X-D21—Coronary artery disease and (2) 400-533—Hypertensive cardiovascular disease. De Castro then retired on March 2, 2006. He subsequently filed a claim for permanent total disability benefits with the GSIS.

GSIS and ECC Rulings

In a decision dated June 20, 2006, the GSIS denied De Castro’s claim because it found that his illnesses were non-occupational. De Castro appealed to the ECC.

At its meeting on June 11, 2007, the ECC Board affirmed the GSIS. It dismissed De Castro’s claim “for lack of merit.” The ECC, however, also made an express observation that CAD is a form of cardiovascular disease included in the list of occupational diseases, contrary to the GSIS ruling. Despite this, the ECC still denied compensation due to what it considered “the presence of factors which are not work-related, such as smoking and alcohol consumption,” and it further noted that manifestations of cardiomyopathy in De Castro’s echocardiography results could be related to his drinking habits.

Proceedings in the Court of Appeals

De Castro sought review from the CA through a petition under Rule 43 of the Rules of Court. He relied on Dominga A. Salmone v. ECC and argued that a causal relationship between his work and the illness resulting in his disability was not an essential requirement, because the illness was listed as an occupational disease. He disputed the ECC’s attribution of hypertension and CAD to smoking and drinking. He further pointed to other possible causes, including job-related stress, and described his PAF positions—ultimately First Sergeant—as comparable to a managerial position in civilian employment because they involved management, administration, and supervision of enlisted personnel within the unit.

The CA granted De Castro’s petition. It noted that, as the ECC itself recognized, De Castro’s illnesses were listed as occupational diseases in Annex “A” of the Amended ECC Rules. It explained that, under the Amended ECC Rules, the sickness must be the result of an occupational disease under Annex “A” in order for the illness and resulting disability or death to be compensable. The CA also explained that it was not necessary for a claimant to prove causal relation between work and illness with a degree of proof beyond what the rules required, citing GSIS v. Baul for the proposition that, in general, a covered claimant suffering from an occupational disease is automatically paid benefits.

The CA acknowledged that the exact etiology of De Castro’s hypertension could not be accurately traced. Still, it emphasized that the etiology of essential hypertension in medical science indicates a relationship between the illness and the nature and conditions of work. It also gave weight to declarations in De Castro’s Certificate of Disability Discharge, including findings that his CAD and hypertensive cardiovascular diseases were aggravated during active service; were not incurred while on AWOL; did not exist prior to entry into service; were incident to service; were not due to misconduct; and were incurred while in line of duty. Based on these considerations, the CA rejected the GSIS and ECC conclusions that De Castro’s illnesses were non-compensable.

Issues Raised in the Supreme Court

The GSIS elevated the matter to the Supreme Court through a petition for review on certiorari and presented two issues: first, whether the CA erred in reversing the GSIS and ECC decisions denying disability benefits; and second, whether De Castro proved that his heart ailments were work-related and/or precipitated by his duties with the Armed Forces of the Philippines (AFP).

The GSIS argued that listing a disease as compensable under Annex “A” was not enough by itself. It contended that the conditions and requisites stated in No. 18, Annex “A” of the Amended ECC Rules had to be satisfied, including requirements involving proof of unusual strain and clinical signs within specific time frames. It maintained that De Castro failed to meet the burden of showing that his heart ailments were caused by his work.

The GSIS also challenged De Castro’s reliance on the Certificate of Disability Discharge. It argued that the certificate reflected findings upon separation and was not binding on GSIS and ECC in determining compensability under Presidential Decree No. 626 and the ECC procedural rules. It further relied on GSIS v. CA to assert that proceedings in the AFP are separate and distinct from the employees’ compensation machinery, and thus AFP conclusions should not control GSIS and ECC determinations.

The GSIS insisted that the CA improperly rejected the ECC’s factual findings, which, it said, were supported by medical references and medical evaluations that linked De Castro’s heart illnesses to his smoking and drinking habits. It therefore asked that the CA be reversed and the ECC’s denial reinstated.

De Castro’s Position

De Castro opposed the petition and asked for its denial. He argued that no additional proof of work connection was required because CAD and essential hypertension were listed as occupational diseases. He relied on Dominga A. Salmone v. ECC to support his view that once an ailment is listed as occupational, the causal relation between the ailment, the disability, and his work is not essential to compensability.

He also disputed the GSIS’s theory that smoking and drinking must have caused his hypertension. He asserted that other causes, including stress associated with military duties, could have contributed to his illnesses. He further contended that the conditions in Item No. 18 were alternative rather than concurrent. De Castro added that his illnesses did not exist prior to entry into service, as reflected in the Certificate of Disability Discharge, and that they were incurred and aggravated during military service.

De Castro maintained that substantial evidence established work connection. He pointed to his duties in PAF operational security and his leadership roles, stressing that his assignments involved urgency and sensitivity that resulted in job stress. He also stated that the GSIS and ECC did not conduct their own separate medical examinations, and instead made a paper evaluation based on hospital findings. He argued that the CA’s findings on service connection were legally beyond review in the manner asserted by the GSIS, since Rule 45 allows review of legal issues only.

Procedural Issue on the Mode of Review

The Supreme Court first addressed the procedural objection. De Castro argued that the petition should be dismissed under Rule 45 because it involved factual questions contrary to the rule’s limitation to questions of law. The Court rejected the objection. It explained that a question of law exists where the controversy concerns what the law is or how it applies to facts, while a question of fact exists where the controversy concerns the truth or falsity of the facts or the existence of claimed facts.

The Court held that the critical facts anchored by the CA were largely undisputed. De Castro experienced chest pains while on duty, was medically diagnosed with CAD and hypertensive cardiovascular disease, and was separated from service and issued a disability certificate. The AFP’s findings indicated smoking and drinking but also supported a work connection, and those findings were affirmed by the AFP’s Disability and Separation Board. The controversy, therefore, did not turn on a disputed set of facts but on whether, under law and jurisprudence, the CA’s conclusions on compensability were correct based on the given facts. The Court therefore treated the matter as appropriate for review under Rule 45.

Determinative Facts for Compensability

The Supreme Court emphasized that the status of De Castro’s ailments upon his separation was undisputed. CAD and hypertensive cardiovascular disease were occupational diseases. It noted that the ECC itself had confirmed CAD as a form of cardiovascular disease included in Annex “A” of the Amended ECC Rules, and that essential hypertension was likewise listed under Item 29 in Annex “A.”

Despite the compensable listing, the GSIS and ECC denied the claim on the ground that De Castro’s CAD was non-work related due to smoking and drinking. The Court observed that De Castro’s military admission notes indicated he was a smoker and a drinker, and on that basis both the GSIS and ECC concluded that these factors made the ailments non-compensable. The Court did not accept those conclusions at face value because they relied on a limited and one-sided view of causes, even though the ECC itself had recognized multiple causes—major and minor—for CAD and hypertension, including age, gender, stress, and other factors.

The Court’s Critique of the GSIS and ECC Approach

The Court found it “strange” that the ECC and GSIS singled out smoking and drinking as determinative factors to deny compensability while disregarding other major and minor causes that the ECC itself listed. The Court stressed that smoking and drinking were undeniably among the causes, but they were not the only causes, and they were not, under the circumstances presented, sole determinants that could automatically bar compensability for occupationally listed diseases.
