The bundling approach can include claims of companies from the same market level (horizontal bundling) or companies from different market levels (vertical bundling). Bundling claims along the supply chain can be an effective solution to counter the so-called passing-on defence which is usually raised by cartel members. Chances of recovering damages increase if the interests of damaged companies along different market levels are aligned.
The bundling of claims is effective and cost efficient for all parties involved. Even cartel members profit from the bundling of claims; it allows cartel members to respond to their liability and to settle claims in one single action.
