Effective, inefficient and illegal investigation of corruption crimes

Purpose of the study on the basis of a general scientific understanding of the effectiveness, the nomination and testing of a hypothesis about whether the methodology for investigating corruption crimes can be effective, and if so, what are the criteria for such inefficiency. Analytical, formal-legal, comparative-legal, situational, classification, practice-oriented and educational approaches are used. All types of specific investigations in cases of corruption offenses are divided into three main types: effective investigation, ineffective and illegal. An effective investigation corresponds to the criteria (principle) of offensiveness and two areas of work of the investigator. Ineffective investigation corresponds to the listed shortcomings (passivity and others). Criteria and classification of illegal criminal prosecution are given. The author's conclusions contain methodological rules for the creation of forensic techniques, taking into account the proposed criteria, typology and classification.
