The Supreme Court on Wednesday heard arguments for overturning the so-called Chevron doctrine, one of the most important principles guiding federal regulation for the past 40 years.
The doctrine, named for a 1984 court case involving Environmental Protection Agency air pollution rules, has been high on the agenda of right-wing groups for years. It holds that when the meaning of a law is disputed, the federal agency’s interpretation should be given deference as long as it is reasonable. Environmental groups fear that overturning the precedent will make it easier for courts to block new pollution regulations, especially those addressing climate change.
