The Supreme Court vacated this longstanding legal principle, not on substantive grounds, but because its application conflicted with the requirements of another statute. Such principle needs to be reinstated in the Black Lung Benefits Act because it provides fairness and improves the administration of benefits. (5) Physicians who read lung x-rays as part of pulmonary assessments used in proceedings for claims under the Black Lung Benefits Act are required to demonstrate competency in classifying chest radiographs by becoming certified as B Readers by the National Institute for Occupational Safety and Health (referred to in this section as NIOSH ). However, investigations have uncovered that there are NIOSH-certified B Readers who have systematically misclassified chest radiographs while employed by coal operators or their law firms for the purpose of opposing claims under such Act. In response, the Department of Labor has directed claims examiners not to credit negative chest x-ray readings for pneumoconiosis by one widely used physician employed at a prominent medical center unless the conclusions of such physician have been rehabilitated .
