Lawsuits challenging OSHA’s ergonomics standard filed by business, labor and insurance groups across the country have been consolidated and will be heard by the U.S. Circuit Court of Appeals for the District of Columbia.

Broad suits challenging the standard’s science, cost estimates, and requirements have been filed by the National Coalition on Ergonomics and the Alliance of American Insurers, and the U.S. Chamber of Commerce and the National Association of Manufacturers. Twelve insurers filed a separate suit dealing solely with worker removal provisions. At least five suits have been brought by labor groups such as the AFL-CIO aiming to strengthen the rules.
