Abstract: This article presents the results of analysis of application of cross-system methods in conveying Russian criminal law and criminal procedure realias in English. The specific examples of Criminal Procedure Code of the Russian Federation illustrate substantial discrepancies in the existing within Russian criminal law systems and Anglo-American type of criminal law system, which cause most difficulties in translation of relevant terminology from Russian into English. Leaning on the considered linguistic and extralinguistic factors, the authors suggest the original solutions of the set communicative tasks. The scientific novelty is substantiated by the absence of the official English version of the Criminal Procedure Code of the Russian Federation, while the need for the corresponding paperwork (request for legal assistance, extradition request, etc.) is significantly growing. The following conclusions are made: criminal procedure discourse of Russian-language and English-language community constructs different and most of the time nonequivalent models of legal reality, which increases the value of comparative jurisprudence for the translator; at the same time, detailed analysis of not only the direct structure of common law and continental law systems, but also methods of their verbalization, allows comprising a more precise portrait of linguistic persona to have an idea of their experience, worldview, thesaurus and other cultural-specific peculiarities that are essential for improving efficiency of communication.
