G.R. No. L-48602 - Sulit vs. Employees' Compensation Commission

Gregorio S. Sulit was employed as a mechanic at the Cavite Naval Shipyard, Naval Shore Establishment, Cavite Naval Base of the Philippine Navy from May 26, 1966 until his death on December 17, 1975, at the age of fifty-three.
His work under general supervision involved:

Inspecting, repairing, and overhauling gas and diesel propulsion engines, auxiliary engines, dock machineries, and other mechanical equipment (including compressors, pumps, reduction gears, windlasses, transmissions, steering control mechanisms, etc.).
Disassembling and reassembling engines and mechanical equipment following instruction manuals.
Taking measurements of engine parts to determine serviceability and preparing reports for verification by the leadingman.
Assembling, installing, and adjusting parts to prescribed clearances; aligning and reinstalling prime movers, compressors, motors, and generators on Philippine Navy vessels.
Performing additional duties as directed by superiors.

Mr. Sulit suffered from persistent backaches and bilateral lumbar pains accompanied by fever and chills, eventually leading to his confinement at the Philippine General Hospital from December 11 until his death on December 17, 1975.
Cause of death:

Acute pyelonephritis – a sudden, severe infection of the kidney typically produced by pus-forming bacteria such as colon bacilli, with contributing factors including urinary flow obstruction from various possible conditions (strictures, calculi, tumors, or prostatic hypertrophy).
Bronchopneumonia – an infection affecting the bronchi and lung tissues, generally occurring as a complication of a debilitating disease.

Fe N. Sulit, the widow of the deceased, filed an employee’s compensation claim under Presidential Decree No. 626.
Her contention was based on the assertion that:

The work of her husband was postural and time-consuming.
Prolonged work in a prone position and under strenuous conditions contributed to a kinking of his ureters.
The resultant constant and progressive urinary stagnancy led to a urinary tract infection and stone formation.

The Government Service Insurance System (GSIS) and the Employees’ Compensation Commission rejected the claim on the basis that:

Pyelonephritis and bronchopneumonia are not classified as occupational diseases, as they do not usually and directly result from the nature of the work.
The risk of contracting such diseases was not increased by the conditions under which Mr. Sulit was employed.

The agencies further clarified that aggravation of a pre-existing disease due to work is no longer a legal basis for granting compensation under Presidential Decree No. 626.
Mrs. Sulit claimed that she was denied a fair opportunity to be heard, arguing a due process violation. However, the filing and processing of claims under GSIS do not mandate a formal adversarial hearing until the claim becomes controversial through appeal.

Whether the nature of Mr. Sulit’s employment directly or indirectly contributed to the development of pyelonephritis and bronchopneumonia.

Consideration of whether the work conditions increased the risk of contracting such diseases.
Evaluation of the causal link between prolonged postural work and the alleged kinking of the ureters leading to urinary stagnancy.

Whether due process was violated in the claim procedure by not affording Mrs. Sulit an opportunity to be heard.

Analysis of the procedural requirements under the GSIS and Employees’ Compensation Commission in processing income benefit claims.
Examination of due process within non-adversary claim filings and subsequent controversy when the claim is appealed.
