Summary

The suit claims this violates California's Cartwright Act and a new law (AB 325) against algorithmic price-fixing. This legal challenge presents a material reputational and financial risk for MPC, with potential damages tied to increased costs for California drivers. The progression of this class-action lawsuit will be important to watch.
