Below is a concise, sourced analysis of what the Court decided and the likely legal-practical consequences (short, actionable points you can use in a client memo or litigation strategy).

The ECJ in ASG 2 has validated the assignment model as a potentially legitimate route for collective enforcement of antitrust damages -- but it set clear limits: Member States may not block effective access to justice by categorical bans, and any restriction must be proportionate and contain safeguards. For Germany, expect increased use of SPVs and litigation finance and consequent adjustments in court practice and legislation; for Hungary, the judgment is a prompt to confirm that national procedural rules do not unduly impede assignment-based collective enforcement and to ensure proportionate safeguards rather than blanket prohibitions.
