Margie Marie Mills v. Director, Office of Workers' Compensation Programs, United States Department of Labor

**What Happened** Margie Marie Mills applied for black lung benefits after her husband, a coal miner, died. Black lung disease (pneumoconiosis) is a serious lung condition caused by breathing coal dust over many years. Mills claimed her deceased husband developed this disease from his work in coal mines and that she deserved survivor benefits as his widow. **The Court's Decision** The court ruled against Mills and upheld the government's denial of benefits. The judges found there wasn't enough proof that her husband worked in coal mines long enough to develop black lung disease. They also determined there wasn't sufficient evidence that coal dust actually caused his lung problems. **What This Means for Workers** This case shows how difficult it can be to win black lung benefits, even when a miner dies from lung disease. Workers and their families must provide strong documentation of both their work history in coal mines and medical evidence linking their health problems directly to coal dust exposure. Simply having lung disease isn't enough—families must prove the disease came specifically from mining work. This highlights the importance of keeping detailed employment records and getting proper medical evaluations that specifically address occupational causes of illness.
