Our modern insistence on democratic social values has engendered an intense debate over the intersection of fundamental rights and contract law. In particular, case law in several European national jurisdictions has exerted significant pressure on traditional contract law instruments to conform more transparently with the fundamental rights enshrined in the EC Charter. This pressure is clearly evident in a number of societal areas subject to contract law, among them employment, housing, and privacy. It can even be argued, as this author does, that fundamental rights intermediate between politics and law. Taking its cue from many initiatives toward the development of a more coherent, even harmonised, European contract law, this book is the first major study to examine the following essential questions with detailed reference to actual judicial developments: • To what extent do fundamental rights affect contract law? • In which types of cases can fundamental rights be applied? • What does the explicit consideration of fundamental rights add to contract law adjudication? The author approaches the analysis along two different avenues: first, a comparative overview of developments in case law, and second, a more general theoretical view on the interaction between fundamental rights and rules of contract law which is tested against examples from various legal systems. The focus throughout is on developments in case law, because the impact of fundamental rights in contract law has been felt on the level of dispute resolution rather than on the level of legislation. Germany and the Netherlands are chosen because their judiciaries have been notable for their early and continuing attention to the theme, and England and Italy for perspectives on developments under common law and civil law systems respectively.
