In 1982 the U.S. Supreme Court held that
American Society of Mechanical Engineers (a nonprofit association) was responsible for treble damages under the
Sherman Act. In 1971 the engineering firm of McDonnell and Miller requested an interpretation of the
ASME Boiler and Pressure Vessel Code from the ASME Boiler and Pressure Vessel Codes Committee. McDonnell and Miller planned to use the response to show that one of their competitors (Hydrolevel Corp) was selling a device not in compliance with the ASME BPV Code. Unknown to ASME's leadership the volunteer chairman of the ASME committee wrote a response to McDonnell and Miller's inquiry that was later used by a McDonnell and Miller salesmen as proof of Hydrolevel's noncompliance. Subsequently, according to Hydrolevel, it never acquired sufficient market penetration for sustaining business, and eventually went bankrupt. Hydrolevel sued McDonnell and Miller, the Hartford Steam Boiler Inspection and Insurance Company and ASME arguing that two ASME subcommittee members acted not only in the self-interest of their companies, but also in violation of the Sherman Anti-Trust Act. == Opinion of the Court ==
