WASHINGTON/NEW YORK -- A U.S. appeals court on Monday overturned the Trump administration's July 2019 rule that sought to suspend a regulation that more than doubled penalties for automakers failing to meet fuel efficiency requirements.
Automakers had protested the hike adopted in 2016 by the Obama administration, saying it could increase industry compliance costs by $1 billion annually. The 2nd U.S. Circuit Court of Appeals in a 3-0 decision Monday said the National Highway Traffic Safety Administration did not make a timely decision to reconsider the penalties.
NHTSA declined comment.
Congress in 2015 ordered federal agencies to adjust a wide range of civil penalties to account for inflation. In response, NHTSA issued rules to eventually raise fines to $14 from $5.50 for every 0.1 mile per gallon of fuel that new cars and trucks consume in excess of the required standards.
A group of states and environmental groups challenged the Trump administration decision.
California Attorney General Xavier Becerra said "the Trump Administration sought to make these penalties meaningless."
Sierra Club senior attorney Alejandra Nunez said the decision means the "Trump Administration cannot give away polluting passes to automakers who lag behind on meeting standards required by law."
Automakers argued the increases would dramatically raise costs, since they would also boost the value of fuel economy credits used to meet requirements. A spokesman for a group representing major automakers said they were reviewing the decision.
Some automakers historically have paid fines instead of meeting fuel efficiency requirements - including some luxury automakers such as Jaguar Land Rover and Daimler AG.
In October, Fiat Chrysler Automobiles said it faced a $79 million U.S. civil penalty for failing to meet 2017 fuel economy requirements after paying a $77.3 million penalty for 2016 requirements.
Environmental groups urged the administration to retain the increase, noting U.S. fuel economy fines have lost nearly 75 percent of their original value because fines had only been increased once -- from $5 to $5.50 in 1997 -- over 40 years.
Separately, a group of 23 states challenged the administration's decision in March to require 1.5 percent annual increases in vehicle efficiency through 2026 -- far weaker than the 5 percent increases adopted under Obama.
