On 12 May 2026, the German Federal Court of Justice (Bundesgerichtshof, BGH) drew the line on how far mass claims aggregation can go (case no. KZR 6/24 – Sammelklage-Inkasso). 

The case involved bundled cartel damages claims relating to approximately 70,000 truck acquisitions totaling approximately EUR 500 million (around USD590 million) on behalf of more than 3,000 assignors from 21 countries. The BGH vacated the appellate judgment and remanded the case to the Higher Regional Court (Oberlandesgericht, OLG) Munich for renewed proceedings.

The decision matters for any company that could face such mass claims—and for any provider of legal-tech-based collective litigation models. It will shape the conditions under which mass claims may be brought before German courts going forward.
