G.R. No. L-56259 March 18, 1983
SYLVIA F. PANANGUI and OLIVIA F. PANANGUI, Minors, represented by ALBERTHA FERRER, petitioners, vs. THE EMPLOYEES’ COMPENSATION COMMISSION and THE GOVERNMENT SERVICE INSURANCE SYSTEM, respondents.

FACTS

Lilia F. Panaqui, a permanent clerk in the Philippine Constabulary, died on September 8, 1976, from acute congestive heart failure and rheumatic heart disease, complicated by her seventh-month pregnancy and premature labor. Her attending physician certified she had rheumatic heart disease since 1967. In August 1976, she was briefly hospitalized for a threatened miscarriage but returned to work. On September 7, 1976, she experienced severe abdominal pain and vaginal discharge, was rushed to the hospital, and died. Her sister, Albertha Ferrer, filed a claim for death benefits under P.D. No. 626 on behalf of Lilia’s two minor children.
The Government Service Insurance System (GSIS) and the Employees’ Compensation Commission (ECC) denied the claim. They ruled the death was not work-connected but was precipitated by her troubled pregnancy, which caused complications leading to heart failure. They emphasized that rheumatic heart disease is not an occupational disease and that her employment as a clerk played no role in her death. The claim was thus deemed not compensable under the new Employees’ Compensation Act.

ISSUE

Whether the death of Lilia F. Panaqui, due to heart failure aggravated by her employment conditions, is compensable under the prevailing compensation laws.

RULING

Yes, the death is compensable. The Supreme Court reversed the ECC decision, applying the principles of social justice and protection to labor. The Court held that while the deceased had a pre-existing heart condition, her work as a clerk, which involved inherent physical and mental exertion, could have aggravated her illness and contributed to her death. The legal logic rests on the established doctrine that when an employee’s exertion in the course of employment, even if usual, accelerates or aggravates a pre-existing disease to the point of disability or death, the resulting injury arises out of the employment and is compensable.
The Court rejected the rigid application of the new law’s listing of occupational diseases, emphasizing a more liberal interpretation in favor of the worker. It cited jurisprudence and legal commentaries stating that compensation is warranted if the employment strain, operating on a weakened condition, precipitates the death, regardless of the degree of exertion or the employee’s prior health. The Court found the ECC’s denial overly technical and contrary to the constitutional mandate of social justice. Consequently, the Philippine Constabulary was ordered to pay death benefits, reimburse medical expenses, and provide burial benefits to the petitioners.
