Annotation

Based of the Criminal Procedure Code of the Russian Federation, judicial positions, and materials from bar association practice, the article analyzes cases of «dual defense» characterized by the simultaneous participation of appointed and retained defense counsel in criminal proceedings. The author examines the contradiction between the right to choose defense counsel and the state's obligation to ensure qualified legal assistance. Particular attention is paid to the institution of challenges as a means of resolving contentious situations and preventing abuses.
