Ovenson v. Employees' Compensation Commission
REITERATIONFacts
1. The Antecedents: The underlying dispute concerns a claim for death benefits filed by Flerida Ovenson for the death of her husband, Serafin Ovenson, who succumbed to adenocarcinoma of the rectum. Serafin Ovenson worked for the Central Bank of the Philippines from 1955 until his death in 1981, holding various positions including laborer, janitor, and senior trade analyst. The Government Service Insurance System (GSIS) denied the claim, asserting that the fatal ailment was attributable to genetic influence and not causally related to his employment. 2. Procedural History: Flerida Ovenson's claim for death benefits under PD 626, as amended, was initially denied by the GSIS. Upon reconsideration, the GSIS reiterated its denial, maintaining that the decedent's ailment was not work-related. The case was then elevated to the Employees Compensation Commission (ECC) for review. The ECC affirmed the GSIS's decision, concluding that there was no basis to attribute the adenocarcinoma of the rectum to the decedent's employment, despite acknowledging that the true etiology of cancer is unknown and that certain lesions can be pre-malignant. 3. The Petition: This case comes before the Supreme Court on a Petition for Review. The petitioner argues that the ECC overlooked the nature and conditions of Serafin Ovenson's employment, contending that his work as a laborer and janitor exposed him to chemical, physical, and parasitic carcinogens, as well as physical and mental stress, which could have contributed to his cancer. The petitioner further asserts that when the cause of a disease is unknown, as with cancer, the law should liberalize the requirement of proving a causal link to employment, citing previous Supreme Court rulings that emphasize a more liberal attitude in deciding compensability claims, especially when there is some basis for inferring a work connection.
Issue(s)
Whether cancer of the rectum was contracted by Serafin Ovenson by reason of his employment. Whether the requirement of proving a causal link between an ailment and working conditions should be liberalized when the cause of the ailment is unknown to medical science.
Ruling
The Supreme Court granted the petition, setting aside the decision of the Employees' Compensation Commission and ordering the respondents to pay the petitioner the full amount of compensation under Presidential Decree No. 626 as amended.
Ratio Decidendi
On whether cancer of the rectum was contracted by Serafin Ovenson by reason of his employment: The Court found no error in the respondent System's denial of the claim based on its medical evaluation attributing the ailment to genetic influence. The Court noted that medical authorities indicate adenocarcinoma of the rectum comprises a significant percentage of malignant tumors, with men being more commonly affected, and the most common age decade being 50-60. While acknowledging that the true etiology of cancer is unknown, the Court stated that certain lesions may be considered pre-malignant and that malignant lesions spread by direct extension, venous, and lymphatic channels. The Court concluded that based on the medical definition, cancer of the rectum could not be caused by the decedent's employment factors, nor could his working environment contribute to its contraction. The other ailments, septicemia and hyperthyroidism, were also not traceable to his employment. On whether the requirement of proving a causal link should be liberalized when the cause of the ailment is unknown: The Court held that under Article 1167(I) of PD 626, a compensable sickness is either an occupational disease listed by the ECC or an illness caused by employment, subject to proof that the risk of contracting it is increased by working conditions. Cancer of the rectum is not listed as an occupational disease. The Court acknowledged the petitioner's contention that exposure to chemicals, insanitary conditions, and stress might have contributed to the illness. However, it reiterated that the GSIS found the illness attributed to genetic influence and that the decedent contracted the disease 16 years after starting work. The Court emphasized that while the presumption of compensability under the Workmen's Compensation Act was abandoned, the liberality of the law subsists. Citing Mercado, Jr. v. Employees Compensation Commission and Cristobal v. ECC, the Court ruled that where the causes of an ailment are unknown or undetermined even by medical science, the requirement of proof of a causal link should be liberalized. It would be an impossible condition to require a claimant to demonstrate a connection between an ailment of unknown origin and working conditions, especially given the claimant's likely lack of resources to employ medical experts. Therefore, the Court found it inequitable to impose such an impossible condition.
Main Doctrine
Where the cause of an ailment is unknown or undetermined by medical science, the requirement of proving a causal link between the ailment and working conditions should be liberalized, as the law cannot demand an impossibility.
