CJEU Clarifies the Standard for Accessing Evidence in Competition Damages Cases

Why It Matters

The decision lowers the evidentiary hurdle for private antitrust damages claims, enhancing enforcement effectiveness across the EU. It also reinforces judicial oversight, protecting defendants from overly broad discovery.

Key Takeaways

• Pre‑action disclosure allowed where national law permits.
• Plausibility threshold lowered to “reasonably acceptable” assumption.
• Commission vertical‑restriction decisions alone don’t prove harm.
• Courts must apply proportionality to avoid fishing expeditions.
• Claimants need factual justification despite Commission infringement finding.

Pulse Analysis

The CJEU’s clarification arrives at a pivotal moment for private competition enforcement in Europe. By confirming that pre‑action disclosure is permissible under the Damages Directive, the Court addresses the chronic information asymmetry that has hampered collective redress actions. Claimants can now seek critical documents before committing to full‑scale litigation, improving the cost‑benefit calculus of pursuing damages and encouraging more robust follow‑on claims against antitrust violators.

A key nuance of the ruling is the “reasonably acceptable” plausibility threshold. Unlike the traditional “more likely than not” standard applied at trial, this lower bar requires only a credible assumption that infringement, harm, and causation exist. This shift eases the evidentiary burden for plaintiffs while still demanding a reasoned justification backed by readily available facts. Defendants, however, retain a powerful shield: national courts must apply strict proportionality tests to prevent fishing expeditions, ensuring that discovery requests remain narrowly tailored and justified.

For practitioners, the judgment signals a need to reassess litigation strategies across EU member states. In jurisdictions that already allow pre‑action disclosure, counsel should promptly prepare concise, fact‑based requests that meet the new plausibility criterion. Conversely, defendants must be prepared to argue proportionality and demonstrate potential undue burden. As national courts interpret the “reasonably acceptable” standard, divergent applications may emerge, creating a patchwork of enforcement landscapes. Companies should therefore monitor local case law closely and consider early settlement or alternative dispute mechanisms to mitigate discovery risks while preserving the right to seek compensation for antitrust harms.
