Nora Collins v. Pond Creek Mining Company, 751 F.3d 180

Johnnie Collins worked in coal-mining jobs for 36+ years; he previously prevailed on a 1988 ALJ finding that he had pneumoconiosis (COPD attributable in part to coal-dust exposure) and was totally disabled; Pond Creek paid benefits until his 1997 death.
Nora Collins filed for survivor benefits after his death; Pond Creek contested that pneumoconiosis hastened the death and administrative proceedings produced conflicting ALJ and BRB rulings over many years.
Treating pulmonologist Dr. Maan Younes (treatment notes, death certificate, and a detailed letter) and reviewer Dr. Dominic Gaziano opined that pneumoconiosis/COPD contributed to death.
Pond Creek-sponsored doctors generally concluded no pneumoconiosis, attributed COPD to smoking, and several (including Drs. Jarboe and Morgan) nonetheless stated COPD hastened death but blamed smoking, not coal dust.
The Fourth Circuit previously held (2006) that collateral estoppel applied to the 1988 ALJ finding that Collins had pneumoconiosis due to coal dust and remanded to determine whether pneumoconiosis contributed to death.
On the most recent review, the Fourth Circuit reversed the BRB and directed an award of survivor benefits: the ALJ had erred in discounting treating-physician and other opinions and substantial evidence shows pneumoconiosis hastened death.

Issue	Collins' Argument	Pond Creek's Argument	Held
Whether the miner’s pneumoconiosis substantially contributed to / hastened his death	Drs. Younes and Gaziano (and others) show COPD (found to be pneumoconiosis) hastened death; this supports survivor benefits	Some doctors said death was purely cardiac or that COPD was smoking-related and did not hasten death from pneumoconiosis	Court held pneumoconiosis hastened death; award benefits — substantial evidence supports death causation when treating and reviewing opinions are considered in light of prior pneumoconiosis finding
Whether the ALJ properly discounted the treating physician and file-review opinions as conclusory	Collins: treating physician’s detailed records and letter, and file review, are sufficiently documented; Toler and prior rulings require crediting such opinions over non-diagnosing doctors	Pond Creek: opinions lacked sufficient explanation (analogizing to Sparks) and non-treating experts’ opinions should be credited	Court held ALJ misapplied Sparks, erred in giving no weight to Younes/Gaziano; Toler favors treating-diagnosing opinions and the ALJ must provide specific persuasive reasons to reject them
