BERLIN -- A UK court ruled that Volkswagen Group used a defeat device to help some diesel vehicles defeat emissions tests, a decision that allows 91,000 customers to proceed with a class action against the automaker.
The case, one of the biggest class-action suits filed in the UK, adds to its legal woes for VW, now in the fifth year of its struggle with the diesel scandal.
The ruling by Judge David Waksman Monday is an interim finding which also said the court was bound by a decision by Germany's transport authority.
VW is facing a wave of litigation by drivers who want their money back for the loss in value of their diesel cars because of the software manipulation exposed by U.S. regulator in September 2015. The scandal has cost the world's largest automaker about 30 billion euros ($32.6 billion) so far and legal proceedings from disgruntled investors and customers are poised to drag on for years.
"Today's ruling is hugely significant for our clients who have been battling for four years to hold Volkswagen to account," said Bozena Michalowska Howells, a lawyer at Leigh Day who represents the owners. "In reaching his decision, the judge rejected virtually all of Volkswagen's arguments and found that the vehicles were fitted with illegal defeat devices."
While the plaintiff lawyers say the ruling means VW "is liable to the group claimants," the automaker said the decision does not determine liability. The court still has to rule on important issues at the heart of the case, the company said.
Volkswagen remains confident that it will not be found liable and that claimants did not suffer any loss, VW spokesman Christopher Hauss said.
