Die Praxis der Beiordnung von Pflichtverteidigern

In the case of German criminal proceedings, in which quantity is criminal defence obtained by court appointed defence counsels (d.c.), and why? How often are court appointed d.c. selected by the judge as opposed to being selected by the accused? According to which criteria do judges choose particular d.c., and which criteria are applied by the accused? Is it true that judges repeatedly choose the same d.c.? And is it correct to assume that accused who are defended by such d.c. waive to appeal more often than others?
This study on the legal reality regarding the appointment of assigned d.c. gives answers to these and other questions. Furthermore, it deals with the evaluation of the consequences of the legal amendment which compels the accused to be defended by a professional d.c. if the accused has been taken into custody. Consideration in terms of legal policy is discussed concerning possibilities of providing for destitute accused d.c. who are not judge-controlled.
