Unwitting subjects of surveillance and the presumption of innocence

摘要

Mass surveillance programmes introduced by several EU Member States influence the protection that citizens enjoy on the basis of fundamental rights and freedoms. This paper focuses on the impact that these programmes have on the legal principle of presumption of innocence. The authors argue that even in those circumstances where the principle does not immediately apply because mass surveillance is undertaken before any criminal charge is issued, the collection of information and potential evidence limits the guarantees offered by the principle during the stages of a legal process. It is argued that mass surveillance programmes undermine the role of the principle of presumption of innocence at the stages of a criminal process and compromise, therefore, the very effectiveness of the legal process.
