Court Rules Death from Pneumonia 16 Years After Pneumoconiosis Diagnosis as Work-Related Injury
▲ Seoul Family Court and Seoul Administrative Court

The bereaved family of a worker who died of pneumonia 16 years after being diagnosed with pneumoconiosis while working at a quarry has won a lawsuit recognizing the death as a work-related injury.
The Seoul Administrative Court, specifically the 3rd Administrative Division, recently ruled in favor of the plaintiffs in a lawsuit filed by the family of the deceased, identified as A, against the Korea Workers' Compensation & Welfare Service. The family had sought to overturn the agency's decision to deny them pneumoconiosis survivor pension and funeral expenses following A's death in October 2023.
A had worked for a long period in dusty environments at sites such as a stone quarry. In September 2007, A was diagnosed with pneumoconiosis (an occupational lung disease) and was subsequently assigned a disability grade of 13-16 in November 2010.
A was hospitalized in September 2023 due to difficulty breathing and passed away in October of that same year.
The cause of death listed on the death certificate was "unspecified pneumonia."
The bereaved family, viewing the death as a work-related injury, filed a claim with the Korea Workers' Compensation & Welfare Service in June 2024 for the pneumoconiosis survivor pension and funeral expenses under the Industrial Accident Compensation Insurance Act.
However, the agency rejected the claim, determining that A had died from an acute myocardial infarction unrelated to pneumoconiosis. The family then filed a lawsuit to challenge this decision.
The court ruled in favor of the family, stating, "A significant causal relationship is recognized between the deceased's pneumoconiosis and its complications, and the death."
Citing the opinion of an expert witness, the court noted that A's overall lung function had gradually deteriorated since beginning treatment for pneumoconiosis, and that the cause of death should be identified as pneumonia.
The court further concluded, "Even if pneumoconiosis and its complications were not the direct cause of death, the chronic worsening of underlying conditions resulting from them led to the development of pneumonia, which the patient could not recover from despite extensive antibiotic treatment, ultimately leading to death."
