Anna Dannreuther has featured in The Lawyer’s Top 20 cases of 2025, for her work for the claimants in The Pan-NOx Emissions Group Litigation (Dieselgate). The claimants allege that diesel vehicles sold in the UK by 19 separate car manufacturers contained “prohibited defeat devices” (PDDs), which reduce the effectiveness of emission control systems.
The High Court group action comprises over 1.2 million claimants and the total alleged damages are more than £6bn. The mammoth case will have its 10-week technical trial in October 2025, followed by a three-week trial in Spring 2026 to hear closing submissions and an eight-week quantum trial expected to start in October 2026. The litigation has seen 13 Group Litigation Orders (GLOs) made, which amounts to around 10 per cent of all GLOs ever granted by the English High Court. Anna acted for the Claimants in securing 10 of the 13 GLOs granted, including at the 6-GLO hearing in January 2024.
