Rechtfertigung und Beweisverbot.

»Justification and Prohibition of Evidence«: This thesis deals with the dogmatically coherent justification of prohibitions of proof in criminal and civil proceedings in the context of evidence obtained by private individuals on their own initiative. It primarily examines the relations between substantive conduct requirements and procedural legal implications. The author differentiates between several points in time and thereby sheds light on provisions of civil law, data privacy law and criminal law.
