Abstract

The scientific heritage of professor S. A. Sheyfer is investigated, with the analysis of his numerous fundamental works on criminal procedure and criminalistics on the penetration of operational and investigative measures into the system of investigative actions. The author emphasizes S. A. Sheyfers ideas about criminal procedural evidence and evidence, the cognitive nature of investigative actions and the prospects for the development of their system, the use of non-procedural cognitive measures in proving. On the basis of four-stage process of formation of new cognitive receptions and those requirements which are provided for their production, S. A. Sheyfer expressed doubts in legitimacy of reckoning by the legislator of control and record of telephone and other negotiations, obtaining information on connections to number of investigative actions. Special attention is paid to the position of S. A. Sheyfer in part of this option penetration of detective-search measures in the system of investigative actions as their legalization in the form of tacit procedural (special secret) investigation, with a justification that the results of the investigative activities of evidence can not be considered because they did not meet the cognitive and procedural characteristics of the trail-governmental action.
