Another federal court has ruled against the auto industry in its attempt to block regulation of greenhouse gas pollution from cars.
The ruling today from U.S. District Judge Anthony Ishii in California supports a September decision by a federal judge in Vermont.
Both courts upheld the rights of states to use the federal Clean Air Act to control greenhouse gases from cars.
Steven Hinchman is a lawyer for the Conservation Law Foundation, which intervened in the Vermont case.
Hinchman points out that both the California and Vermont cases followed a U.S. Supreme Court decision in April that affirmed the government's power to regulate global warming pollution.
This is strike three for the automakers. They've now lost in this year alone three different federal cases trying to block regulation of greenhouse gas emissions from motor vehicles. When the best scientists in the whole world are saying this is an urgent crisis, and when the governments are responding, it's time for the automakers to quit litigating and start innovating and producing clean cars.
More than a dozen states have followed California's lead and have adopted tough new emissions standards.
Both Vermont Attorney General William Sorrell and Governor Jim Douglas praised the ruling.
They said the California decision upholds the right of states to require aggressive pollution control measures for vehicles.
