Renault Group succeeds in England & Wales “Prohibited Defeat Devices” diesel emissions litigation

Finding in the Renault Group's favour, the High Court of Justice has today handed down its liability judgment in the long running London diesel emissions litigation.

In an extensive ruling, culminating years of proceedings involving thousands of pages of submissions, dozens of experts’ reports and witness statements, as well as a several months’ long trial, the High Court rejected all claims against Renault.

Renault Group welcomes this decision, which is fully consistent with its long-held position that its vehicles have been and are designed, engineered, and manufactured in accordance with all applicable regulatory requirements.

Renault Group will now pursue the recovery of its legal costs from the large institutional insurers and hedge funds who backed these claims in the hope of a financial gain.
