Draft Guidance Paper − Quantifying harm in actions for damages based on breaches of Article 101 or 102 of the Treaty

Policy field

Competition: antitrust

Target group

All interested parties

Period of consultation

From 17.06.2011 to 30.09.2011

Objective of the consultation

The full effectiveness of the EU antitrust rules requires that any individual can effectively claim compensation for the harm caused by an infringement of these rules. Damages actions based on an infringement of the EU antitrust rules play a specific function in the overall enforcement of these rules, complementing public enforcement. While the right to compensation is recognised by EU law, a range of obstacles currently stand in the way of injured parties effectively receiving the compensation to which they are entitled.

In the 2005 Green Paper on damages actions for breach of the EC antitrust rules, the Commission identified difficulties in quantifying the individual harm suffered by injured parties as a key issue in antitrust damages actions. In its 2008 White Paper, the Commission announced its intention to draw up a framework with pragmatic, non-binding guidance on quantifying the harm suffered in such actions. This suggestion was welcomed by a wide range of stakeholders.

In preparation of such non-binding guidance and to make it suited to the practical needs of judges and parties in antitrust damages cases, DG Competition sought expertise from legal and economic practitioners and academics, and analysed current practices in the quantification of antitrust harm suffered by injured parties in a range of cases before national courts.

On this basis, DG Competition has drawn up the present Draft Guidance Paper, which provides insights into the harm caused by infringements of the EU antitrust rules to different categories of injured parties and sets out some of the methods and techniques currently available in order to quantify the harm suffered by injured parties.
