Is a polygraph evidence in a case?

Currently, the rules of the Criminal Procedure Code do not provide for the possibility of verifying the truthfulness of the testimony of a person (suspect or accused) using a polygraph (lie detector) or accepting the information obtained in this way as evidence. Today, it is possible to use the polygraph only in a narrow professional circle. Therefore, the results of using a polygraph are not evidence within the meaning of Art. 84 of the Criminal Procedure Code, and in criminal proceedings they can be used only in combination with other appropriate and admissible evidence.
