LUXEMBOURG -- Luxembourg has started criminal proceedings in response to the Volkswagen Group diesel-emissions scandal, saying on Monday that regulators had been cheated by car manufacturers.
Following an investigation into the scandal, the European Union country's infrastructure minister said he was lodging a complaint with prosecutors without naming any of the parties under suspicion.
"We have decided that, as there is a large probability that a defeat device was used, to launch a lawsuit against unknown persons," minister Francois Bausch told journalists.
In documents handed out to reporters at a news conference, Luxembourg's infrastructure ministry described itself as "a victim of criminal action that led it to certify cars," saying it would not have done so had the tests not been falsified.
Luxembourg is among seven nations under scrutiny by Brussels regulators for failing to impose the kind of penalties Volkswagen has faced in the United States over its use of illegal "defeat device" software to mask toxic diesel emissions.
Volkswagen has already announced 18.2 billion euros ($19.6 billion) of provisions to cover the costs of the cheating scandal.
However, its legal problems are not over yet. Fish distributor Deutsche See has said it is suing the company for misrepresenting a fleet of vehicles it leased as environmentally friendly, becoming the first major German customer to sue Europe's biggest carmaker over its diesel-test cheating.
