"It follows that a purely black letter, descriptive approach to privacy law would be of limited utility. There are many gaps in privacy regulation and there is considerable scope for debate regarding the manner in which exiisting privacy laws should be interpreted and applied. Moreover, the law in this area is in a state offlux. A conceptual understanding of privacy is necessary in order to make a judgment on the policy questions in this area. Questions such as: to what extent should the law commit itself to protection of privacy?; what is the proper balance to be struck between privacy and other rights?; how should the existing law be interpreted and developed in the future? In light of this, a significant portion of this book will analyse the philosophical foundations of the right to privacy."
