The collected essays in this book discuss the interaction between law and technology and the normative role of information technology. More precisely, this book focuses on the way information and communication technologies regulate our behaviour. Can information technology be an alternative for legal regulation and, if so, what are the risks? Can technology be used to circumvent constitutional safeguards? Is technology regulation just another form of self-regulation? Is regulation through technology distorting traditional balances of rights? Those are all questions that are discussed from different angles, and with different legal perspectives. The essays also discuss more general issues of legitimacy, and of transparency of the normative role of information technologies. We hope to provide a meaningful contribution to the lively debate on the relationship between law and information technology.
