Court-approved antitrust mediator

Dr Helmut Janssen is an antitrust mediator approved by the competent German Court of Appeal. As a mediator, he specialises in the out-of-court settlement of claims arising under antitrust law, e.g. for damages, supply and injunctive relief. A procedure before an antitrust mediator offers several advantages. An agreement concluded by the parties in front of a court-approved mediator has the same effect as a state court judgment.
