Der Kronzeuge im Strafgesetzbuch

Since 2009, the German criminal code has contained a far-reaching accomplice evidence rule (“Kronzeugenregelung“) in its sec. 46b. In his book, the author deals intensively with different aspects of this recent legal norm. He concentrates both on practical and on dogmatic problems concerning this highly contentious legal concept. In doing so, he critically analyses some of the traditional prejudices towards so-called supergrasses, particularly the compatibility with the principle of the mandatory prosecution of offenses (Legalitätsprinzip) as well as with the principle of guilt (Schuldprinzip). The core of the work is a nationwide empirical study which examines the practical application of the accomplice evidence rule. It contains an online survey among judges, prosecutors, lawyers and policemen, an analysis of court decisions and (for the first time ever) a student survey about the present topic. It is the largest empirical study on accomplice witnesses in Germany so far.
