The U.S. Is Suing Volkswagen

The U.S. Justice Department on Monday filed a civil lawsuit against Volkswagen AG for allegedly violating the Clean Air Act by installing illegal devices to impair emission control systems in nearly 600,000 vehicles.

The allegations in the lawsuit carry penalties that could cost Volkswagen billions of dollars, a senior Justice Department official said.

“The United States will pursue all appropriate remedies against Volkswagen to redress the violations of our nation’s clean air laws,” said Assistant Attorney General John Cruden of the environment and natural resources division at the Justice Department.

The Justice Department lawsuit accuses Volkswagen of four counts of violating the U.S. Clean Air Act, including tampering with the emissions control system and failing to report violations.

The lawsuit is being filed in the Eastern District of Michigan and then transferred to Northern California, where class-action lawsuits against Volkswagen are pending.

“We’re alleging that they knew what they were doing, they intentionally violated the law and that the consequences were significant to health,” the senior Justice Department official said.

The Justice Department has also been investigating criminal fraud allegations against Volkswagen for misleading U.S. Consumers and regulators. Criminal charges would require a higher burden of proof than the civil lawsuit.

The civil lawsuit does not preclude the Justice Department from pursuing criminal charges against Volkswagen, said the Justice Department official.

VW spokeswoman Jeannine Ginivan said the automaker did not have an immediate comment on the lawsuit.
