Abstract
When covering the problems of the system of investigative actions, S.À. Sheifer invariably included in their number the detention of the suspect, during which procedural fixation received important information for the case – the time, place and reason for the detention of a particular person. For such an approach, the Criminal Procedure Code of 1960 had legal and regulatory grounds. In the Russian Criminal Procedure Code of 2001 there are no similar direct instructions, but S.À. Sheifer under the current law insisted on the cognitive nature of the detention and the evidentiary significance of its protocol. At present, some authors have made judgments about the inaccuracy of the described position of S.À. Sheifer and proposed arguments that refute the possibility of classifying suspect as a consequence of collecting evidence, not only under the current criminal procedural law, but also in principle specificity of the procedural nature of this action itself. The article supports the position of S.À. Sheifer, critical judgments about the current practice of detaining a suspect and suggested ways to improve it.
