All criminal justice systems in rule-of-law states attempt to prevent justizmord cases. Unfortunately, this intention is not always successful. This statement is illustrated by both Hungarian and foreign examples.  Both Hungarian and international scientific research reveals that the identity parade (line-up) method plays a key role in the miscarriage of justice cases. So it is important (basic)/vital interest to prepare preventing methods in this field, or to reveal/disclose the causes of final serious mistakes. For this purpose, the author examines the identity practical method and legal (police) rules in Germany and Italy. At the end of the study, the author formulates the potential legal and criminalistic/forensic development possibilities, the lessons and his conclusions for the powerful/efficient and fair criminal procedure rules and for better law enforcement practice.
