Die Unwirksamkeit von Verträgen nach französischem Recht

The invalidity of contracts has fascinated French lawyers for centuries. Jean-Philippe Klein analyzes why the invalidity of contracts is considered as one of the most obscure subjects in French law. The thesis encompasses 2000 years of the history of the invalidity of contracts and provides a thorough analysis of invalidity-related French case law. The author summarizes the conclusions of his work in final arguments. In an annex, he also evaluates the provisions relating to invalidity in the draft revision of the Code Civil (»Avant-projet Catala«) as well as in the French draft of the second edition of the »Lando Principles.«
