The article examines the issue of the use of indirect evidence in the process of proving a criminal case. There is an ambiguity in the approaches of scientists to the importance of indirect evidence. Attention is paid to the problem of assessing the totality of evidence in situations where indirect evidence prevails in the case file. It is indicated that the most important criterion here will be the consistency and interrelation of evidence. The position of scientists who propose to legislate such an independent property of evidence as interconnection is supported. It is proposed to amend Article 88 of the Code of Criminal Procedure of the Russian Federation concerning the assessment of the sufficiency of evidence by supplementing this provision with the words "all evidence collected together is subject to assessment in terms of their consistency and sufficiency to resolve a criminal case".
