Information requirements have become a key element of consumer policy at the European level and are also gaining increasing importance in all other areas of private law. The law stipulates that information provided should not be misleading and also involves requirements regarding the fairness and objectivity of what has been provided. In addition to controlling the veracity of what is voluntarily offered by traders, the law increasingly requires disclosure of certain information. This volume focuses especially on the question of how these information requirements influence the party autonomy. International contributors explore in various contexts whether the legislative policy regarding the information requirements and their relationship to party autonomy has been properly thought through.
