As you probably know, it is almost impossible to get damages for breach of the antitrust rules in Europe. Instead, if you are a corporation, you go crying to the government for some state handout or protective regulation. For some time, the Commission has been looking into ways to improve the ways in which the tort system works in the member States.
The idea of the White Paper is to set out a certain number of policy choices so that they may be examined and discussed before an actual proposal is made. It deals with such matters as standing, discovery, costs, quantum of damages, limitation periods and such like. The White Paper itself is superficial and probably not very constructive.
Nevertheless, it invites comments, to be submitted to the Commission by July 15th, 2008.
Much more detailed and helpful is the Staff Working Paper which should be read also. Why the Commission wants to make life difficult by splitting the two documents is a mystery.
A "white paper" is a document "containing proposals for Community action in a specific area. In some cases they follow a Green Paper published to launch a consultation process at European level. When a White Paper is favourably received by the Council, it can lead to an action programme for the Union in the area concerned."
