Mercedes-Benz Class Action

Mercedes-Benz Class Action

The Claim

Piper Alderman has filed a class action in the Supreme Court of Victoria on instructions from Krisoula El-Helou, the plaintiff, against Mercedes-Benz Australia/Pacific Pty Ltd, and its two German parent companies, which manufactured and supplied diesel vehicles in Australia (together, Mercedes-Benz) (the El-Helou Proceeding).

The plaintiff commenced the proceeding on behalf of persons, referred to as ‘group members’, who acquired an equitable or legal interest in a Mercedes-Benz diesel vehicle in Australia (including on hire purchase) between 1 January 2008 and 22 January 2024 (Relevant Period), which contained a “defeat device” (Affected Vehicle).

The plaintiff alleges that during the Relevant Period, Mercedes-Benz manufactured and supplied the Affected Vehicles to her and to group members and that the vehicles emitted nitrogen oxides (NOx) in excess of the permitted regulatory levels. The plaintiff seeks compensation from Mercedes-Benz for losses suffered, on the basis that Mercedes-Benz misrepresented that the Affected Vehicles complied with regulatory requirements.

A further summary of the class action is available in the Group Proceeding Summary Statement accessible below.

Other Mercedes Class Action

In addition to this class action, there was another class action on foot against Mercedes-Benz Australia/Pacific Pty Ltd and one of its German parent companies, Mercedes-Benz Group AG, in the Supreme Court of Victoria. That class action was brought by plaintiffs Paul Wawryk and Craig Stubbings and was commenced on behalf of group members who “purchased or leased or otherwise acquired a legal interest” in certain Mercedes-Benz vehicles (being engine models OM 607, OM 622, OM 626, OM 640, OM 651) between 2009 and 22 November 2022 (the Wawryk Proceeding).

Status of the Proceeding

On 21 October 2024, the Honourable Justice Nichols made court orders to the effect that  the El-Helou Proceeding will continue, while the Wawryk Proceeding has been permanently stayed (i.e. will no longer proceed).

Piper Alderman and Gerard Malouf Partners, the solicitors for the plaintiffs in the Wawryk Proceeding, will now work together in prosecuting the El-Helou Proceeding. Piper Alderman will remain the solicitors on the record in the El-Helou Proceedings, and Gerard Malouf Partners will act as our Agent.
