High Court Rules in Favor of Carmakers
Lady Justice Cockerill handed down judgment on Thursday in the Pan-NOx emissions litigation, rejecting most of the principal allegations against Mercedes-Benz, Ford, Renault, Nissan, and the Stellantis brands Peugeot and Citroën. The ruling marks a substantial early win for the automakers, who had denied the claims throughout the proceedings. reuters.com fountaincourt.uk law360.com globalbankingandfinance.com
The case, brought on behalf of approximately 1.6 million UK vehicle owners, alleged that the manufacturers deliberately misled motorists by using prohibited “defeat devices” — software that detected when vehicles were undergoing emissions testing and adjusted performance to meet nitrogen oxide limits. Lawyers for the claimants had valued the litigation at roughly £6 billion. reuters.com bbc.com reuters.com globallegalpost.com
A Decade-Long Legal Battle
The judgment comes nearly 11 years after the Volkswagen emissions scandal first exposed the use of defeat devices in diesel cars in 2015. The trial before Lady Justice Cockerill ran for approximately three months from October 2025, examining a sample of 20 diesel vehicles produced by the five lead defendants. Closing submissions were heard in March 2026. reuters.com motorfinanceonline.com lawgazette.co.uk
The BBC reported that the judge found the major car firms did not install devices to cheat emissions testing. According to Bloomberg Law, the manufacturers “largely won” the case over allegations they manipulated vehicles to pass emissions tests. bbc.com news.bloomberglaw.com
What Comes Next
Despite the broad victory for carmakers, the Fleet News reported that the court made specific findings against two particular strategies employed by manufacturers, though the ruling mostly cleared the automakers overall. The case involved 14 manufacturers in total, with the five lead defendants chosen to produce a binding judgment that would guide the remaining claims. reddit.com fleetnews.co.uk
Volkswagen had previously settled its UK dieselgate claims out of court in 2022, paying £193 million to 91,000 British motorists. The Pan-NOx litigation represents a far larger scale, and despite the ruling, further legal proceedings may follow depending on the specific findings regarding those two strategies identified by the court. bbc.com
