Outcome: Very favorable
The issue in this case was whether the Environmental Protection Agency (EPA) regulations governing National Ambient Air Quality Standards for Particulate Matter adequately protected public health.
The AMA supports the health based provisions of the Clean Air Act.
Effective December 18, 2006 and pursuant to the Clean Air Act, the EPA revised its regulations governing National Ambient Air Quality Standards for Particulate Matter. The industries regulated by these new regulations complained that the new standards were unduly onerous and sued to have them made more lenient. At the same time, several public health organizations complained that the new standards were unduly lenient, and they sued to have them made stricter. These various lawsuits were consolidated into a single action before the United States Court of Appeals for the D.C. Circuit.
On February 24, 2009, the Court of Appeals struck down the regulations, finding them contrary to law and inadequately reasoned. The court observed that the EPA had failed to consider relevant epidemiological studies and thus did not sufficiently protect the public health. It remanded the issue to the EPA for further consideration.
The AMA and four specialty medical societies filed an amicus brief, arguing that the modified regulations should be made more stringent.
