A federal court helps the state of California in its efforts to reduce emissions from automobiles.
One of the primary procedural issues addressed in American law is whether a question presented is governed by federal law or by state law. The pre-emption doctrine provides that a state legislature may not regulate a federal issue.
A California federal district court recently ruled on the inapplicability of this doctrine with respect to the State of California’s request for a waiver from Environmental Protection Agency (EPA) standards for automobile emissions. The State wants to mandate lower emissions in passenger vehicles, such that California vehicles are more environmentally friendly than the national average.
At issue in the case was whether federal fuel efficiency standards pre-empt the state’s power to regulate emissions of greenhouse gasses. Automobile manufacturers argued that if the EPA grants the waiver, automobiles will be held to higher gas mileage standards than are currently required under federal law. The defendants, the State of California and a number of environmental groups, moved for summary judgment on the issue of whether federal law pre-empted the proposed California regulations and whether the proposed regulations were pre-empted by US foreign policy.
The court found that “both [the federal] EPA and California…are equally empowered through the Clean Air Act to promulgate regulations that limit the emission of greenhouse gasses.” This means that if the EPA grants California the waiver, California will be able to require lower vehicle emissions. The court also found that the foreign policy argument, which was that the California regulations would impede federal efforts to persuade developing countries to reduce their emissions, did not prevent the EPA, and thus California acting under a waiver granted by the EPA, from regulating environmental matters.
The US Supreme Court and several federal district courts have recently ruled along similar lines. In April, the Supreme Court found that the EPA has the authority to assist states that want to enact emission controls. A federal court in Vermont found that Vermont’s tailpipe emission standards were valid and did not violate federal law. California, Vermont, and ten other states have enacted laws requiring reduced tailpipe emissions.
Federal Ruling Boosts California’s Efforts to Curb Auto Emissions
Now that a judge has nixed an industry suit, EPA waiver is the only thing keeping California from mandating lower emissions
