Das Prognoseprinzip im vertraglichen Dauerschuldverhältnis

Predictions of the future affect all areas of law. For the first time, this work offers a cross-thematic examination of the connected legal problems for the law of contractual long-term relationships. Among other things, it discusses the necessity of predictions, the correct time of prediction, the relevant degree of probability and practical solutions for reducing legal uncertainties. The discussion is mainly based on questions from labour law, tenancy law and corporate law, where forecasting problems have already gained more attention for some time. The possibilities and limits of generalising the solutions found in these areas of law are comprehensively demonstrated. The author has been awarded the Hans Mühlenhoff Foundation Prize at the University of Osnabrück and the Science Prize of the Foundation Theory and Practice of Labor Law (Wolfgang Hromadka Foundation).
