G.R. No. 112313 - Evangelista vs. Sandiganbayan

Petitioner: Angelita Tanedo, widow of Francisco Tanedo.
Respondents: Employees’ Compensation Commission (ECC) and the Government Service Insurance System (GSIS), representing the Ministry of Agrarian Reform.

Francisco Tanedo was employed as a janitor-laborer in the District Office of the Ministry of Agrarian Reform at Tarlac, Tarlac.
His job responsibilities included cleaning comfort rooms and watering plants.
Prior employment history included work with the former Bureau of Public Highways starting in February 1955, and positions such as “Capataz Timekeeper” and “Construction Capataz” before his transfer to the Ministry on June 29, 1972.

In December 1976, Francisco Tanedo was observed to suffer from “puffiness of face, pedal edema, and progressive abdominal enlargement.”
He was confined at the Central Luzon Doctors Hospital where his condition was diagnosed as “renal insufficiency secondary to chronic renal disease.”
A recurrence of his illness led to a second hospitalization in January 1978 at the Tarlac Provincial Hospital, where he failed to respond to treatment.
In September 1978, he was readmitted to the Tarlac Provincial Hospital, where he died twenty days later following further deterioration of his condition.

Following her husband’s death, petitioner filed a claim for death benefits with the respondent GSIS.
The GSIS denied her claim on the ground that the illness causing death—identified as “chronic glomerulonephritis”—was not among the compensable illnesses provided under the law, based on the Medical Director’s report dated May 7, 1979.
Petitioner argued that the final diagnosis was “glomerulonephritis; renal hypertension; and Koch’s pulmonary,” suggesting a connection with occupational hazards.

After GSIS denied her motion for reconsideration, petitioner elevated the matter to the ECC, which affirmed GSIS’s decision.
Under the law, a compensable sickness is defined as either a disease listed as an occupational disease (as detailed in Annex “A” of the Amended Rules on Employees’ Compensation) or any disease whereby the employee must prove that the risk of contracting it was increased by working conditions.
Petitioner was required to produce evidence showing both that her husband suffered from the compensable disease and that his working conditions contributed to contracting the said illness.

Whether the petitioner’s claim for death benefits is valid and compensable when based on a diagnosis of “chronic glomerulonephritis,” along with complications such as renal hypertension and Koch’s pulmonary, as opposed to the illness being explicitly listed as compensable under the applicable rules.

Whether the evidence on record is sufficient to establish a causal relationship between the deceased’s employment conditions and the manifestation or aggravation of the disease leading to his death.

Whether the petitioner's reliance on the pre-existing presumption that any illness causing death or disability was work-related is tenable given the statutory change effective January 1, 1975.
