Case Brief Summary & Legal Analysis

General Brief
4 min read

tl;dr: OSHA attempted to lower the workplace exposure limit for benzene, a carcinogen, based on a policy of reducing risk to the lowest feasible level. The Supreme Court invalidated the rule, holding that OSHA must first make a threshold finding that the existing limit poses a “significant risk.”

Legal Significance: Established the “significant risk” test, requiring an agency to make a threshold finding of a significant health risk before it can issue a regulation under the OSH Act. This represents a major judicial check on agency authority to regulate under conditions of scientific uncertainty.

Case Facts & Court Holding

Key Facts & Case Background

The Occupational Safety and Health Administration (OSHA) promulgated a new standard reducing the permissible workplace exposure limit (PEL) for benzene, a toxic substance and known carcinogen, from 10 parts per million (ppm) to 1 ppm. The evidence of benzene’s harmful effects at exposure levels of 10 ppm or below was inconclusive. OSHA did not determine that the 10 ppm standard was unsafe. Instead, the agency acted under its general “carcinogen policy,” which presumed that there is no safe level of exposure to a carcinogen. Based on this policy, OSHA contended that § 6(b)(5) of the Occupational Safety and Health Act (OSH Act) required it to set the standard at the lowest technologically and economically feasible level. The agency made no explicit finding that exposure at 10 ppm posed a “significant risk” of harm, arguing it was not required to do so. It assumed that because benzene is a carcinogen, some risk must exist at any level above zero and that reducing exposure would yield some benefit. The American Petroleum Institute and other industry groups challenged the standard as exceeding OSHA’s statutory authority.

Court Holding & Legal Precedent

Issue: Must the Secretary of Labor, before promulgating a standard for a toxic substance under the Occupational Safety and Health Act, make a threshold finding that the substance poses a significant risk of harm at the current exposure level?

Yes. The plurality affirmed the lower court’s judgment invalidating the standard.
