Villavert vs. Employees' Compensation Commission & Government Service Insurance System (Philippine Constabulary)

Death benefits are compensable under the Employees' Compensation program when the evidence shows that the employee's illness was directly caused or at least aggravated by the duties he performed, even if the illness is not listed as an occupational disease, because all doubts in the implementation and interpretation of the Labor Code, including its implementing rules and regulations, shall be resolved in favor of labor.

The petitioner, Domna N. Villavert, is the mother of the late Marcelino N. Villavert, who was employed as a Code Verifier in the Philippine Constabulary. She filed a claim for income benefits for the death of her son under P.D. No. 626, as amended, with the Government Service Insurance System on March 18, 1976. The claim was denied on the ground that acute hemorrhagic pancreatitis is not an occupational disease and that the petitioner failed to show a causal connection between the fatal ailment and the nature of his employment.

Marcelino N. Villavert was employed as a Code Verifier in the Philippine Constabulary. In addition to his duties as Code Verifier, he also performed the duties of a computer operator and clerk typist. In the morning of December 11, 1975, Marcelino reported as usual to the Constabulary Computer Center at Camp Crame, Quezon City. He performed his duties not only as code verifier but also handled administrative functions, computer operation, and typing jobs due to shortage of civilian personnel.

Late in the afternoon of December 11, 1975, although he was complaining of chest pain and headache after a whole day of strenuous activities, Marcelino was still required to render overtime service until late in the evening of the same day, typing voluminous classified communications, computing allowances, and preparing checks for the salary of Philippine Constabulary and Integrated National Police personnel throughout the country for distribution on or before December 15, 1975. He went home late at night and, due to fatigue, went to bed as soon as he arrived without taking his meal. Shortly thereafter, he was noticed by his mother gasping for breath, perspiring profusely, and mumbling incoherent words. Despite efforts to revive him, he was rushed to the UE Ramon Magsaysay Memorial Hospital where he was pronounced dead at 5:30 o'clock in the morning of December 12, 1975, without regaining consciousness. The cause of death was acute hemorrhagic pancreatitis.

To support the claim, the petitioner submitted a certification from Lt. Colonel Felino C. Pacheco Jr., commanding officer of the Philippine Constabulary, stating that Marcelino had been performing duty assignments in addition to his appointment as Code Verifier, including as computer operator subject to excessive heat and cold, and as clerk typist responsible for typing important communications. The certification also stated that due to shortage of qualified civilian personnel, he was given excessive work responsibilities which could have aggravated his ailment; that he often took his meals irregularly late due to the nature of his work; that he used to perform rotation duties leaving him insufficient time to consult the Constabulary Medical Dispensary; that he never drank alcoholic liquor, neither smoked nor engaged in immoral habits; and that he died in line of duty after retiring from his night shift. This certification was corroborated by the affidavit of Rustico P. Valenzuela, Chief Clerk of the Constabulary Computer Center, who confirmed that Marcelino was complaining of chest pain and headache prior to his death but was obliged to go on strenuous duty on the night of December 11, 1975, thereby aggravating his ailment due to excessive work, exposure to heat and cold, operating computer machines, and over fatigue that caused his sudden death.

The Employees' Compensation Commission, citing a medical textbook, stated that acute hemorrhagic pancreatitis is "acute inflammation with hemorrhagic necrosis of the pancreas" and occurs most commonly in association with alcoholism, biliary tract disease, or as a complication of peptic ulcer, mumps, viral hepatitis, or following the use of certain drugs. However, the Medico Legal Officer of the National Bureau of Investigation stated that the exact cause of acute hemorrhagic pancreatitis is still unknown despite extensive research, although most research data agree that physical and mental stresses are strong causal factors in the development of the disease.

• Causal Connection: Petitioner argued that Marcelino N. Villavert died of acute hemorrhagic pancreatitis as a result of his duties as a code verifier, computer operator, and typist of the Philippine Constabulary, submitting certifications and affidavits from his commanding officer and chief clerk attesting to the strenuous nature of his work and its aggravating effect on his ailment.
• Absence of Other Causes: Petitioner presented evidence that Marcelino never drank alcoholic liquor, neither smoked nor engaged in immoral habits, negating the common medical associations of the disease with alcoholism.
• Liberal Construction: Petitioner implicitly invoked the principle that doubts in the implementation and interpretation of the Labor Code should be resolved in favor of labor.

• Non-Occupational Disease: The Government Service Insurance System and the Employees' Compensation Commission denied the claim on the ground that acute hemorrhagic pancreatitis is not an occupational disease and that the petitioner failed to show a causal connection between the fatal ailment and the nature of his employment.
• Lack of Evidence: Respondents maintained that the petitioner did not present evidence that the illness was caused or aggravated by the nature of his duties as an employee of the Philippine Constabulary.
• Medical Science: The Employees' Compensation Commission cited medical literature associating the disease with alcoholism, biliary tract disease, drug use, or trauma, and noted that approximately 20% of patients have no apparent underlying or predisposing cause.

• Compensability of Death Benefits: Whether the death of Marcelino N. Villavert from acute hemorrhagic pancreatitis is compensable under P.D. No. 626, as amended, notwithstanding that the disease is not listed as an occupational disease.

• Compensability of Death Benefits: Yes. The death of Marcelino N. Villavert from acute hemorrhagic pancreatitis was directly caused or at least aggravated by the duties he performed as coder verifier, computer operator, and clerk typist of the Philippine Constabulary. The decision of the Employees' Compensation Commission was set aside, and the Government Service Insurance System was ordered to pay the petitioner death benefits in the amount of P6,000.00.

• Compensability of Death Benefits: The Court found that the record clearly showed that Marcelino N. Villavert died of acute hemorrhagic pancreatitis which was directly caused or at least aggravated by the duties he performed. The Court noted that there was no evidence at all that Marcelino had a "bout of alcoholic intoxication" shortly before he died, nor was there a showing that he used drugs. The Court relied on the certifications and affidavits of his commanding officer and chief clerk, which established that he was required to render strenuous overtime service despite complaining of chest pain and headache, and that his ailment was aggravated by excessive work, exposure to heat and cold, operating computer machines, and over fatigue. The Court further invoked Article 4 of the Labor Code of the Philippines, as amended, which provides that "All doubts in the implementation and interpretation of this Code, including its implementing rules and regulations shall be resolved in favor of labor." The Court also considered the statement of the Medico Legal Officer of the National Bureau of Investigation that physical and mental stresses are strong causal factors in the development of the disease.

• Liberal Construction in Favor of Labor — Article 4 of the Labor Code of the Philippines, as amended, provides that all doubts in the implementation and interpretation of the Code, including its implementing rules and regulations, shall be resolved in favor of labor. The Court applied this principle to grant the claim for death benefits, resolving the doubt as to whether the disease was caused or aggravated by the employment in favor of the petitioner.

• "From the foregoing facts of record, it is clear that Marcelino N. Villavert died of acute hemorrhagic pancreatitis which was directly caused or at least aggravated by the duties he performed as coder verifier, computer operator and clerk typist of the Philippine Constabulary." — This passage states the Court's core factual finding that the fatal ailment was work-connected, forming the basis for the grant of death benefits.
• "It should be noted that Article 4 of the Labor Code of the Philippines, as amended, provides that 'All doubts in the implementation and interpretation of this Code, including its implementing rules and regulations shall be resolved in favor of labor.'" — This passage articulates the controlling statutory principle that resolved any doubt in the interpretation of the compensation rules in favor of the claimant.

N/A — The decision does not cite any prior jurisprudence.

• Article 4, Labor Code of the Philippines, as amended — The Court applied this provision mandating that all doubts in the implementation and interpretation of the Labor Code, including its implementing rules and regulations, shall be resolved in favor of labor. This principle was invoked to resolve the question of compensability in favor of the petitioner.
• P.D. No. 626, as amended — This is the statutory basis of the claim for death benefits under the Employees' Compensation program, under which the petitioner filed her claim with the Government Service Insurance System.

Teehankee (Chairman), Makasiar, Guerrero, and Plana, JJ., concurred.

• Melencio-Herrera, J., dissenting — The dissent argued that Section 1(b), Rule III of the Amended Rules on Employees' Compensation explicitly requires that for a sickness and resulting death to be compensable, the sickness must be the result of an occupational disease annotated under Annex "A" of the rules, or proof must be shown that the risk of contracting the disease is increased by the working conditions. Since acute hemorrhagic pancreatitis is not listed as an occupational disease and the petitioner did not present evidence that the risk of contracting it was increased by the working conditions, the claim was not compensable. The dissent also noted that the statement of the Medico Legal Officer of the NBI that physical and mental stresses are strong causal factors was not scientifically confirmed research data, and that the exact cause of the disease is still unknown.
