Abstract
This article examines current issues related to the accuracy of translating legal terminology in the criminal procedure legislation of the Republic of Kazakhstan. Particular attention is paid to the implementation of the fundamental principle of the language of judicial proceedings and its impact on the quality of law enforcement. The study aims to provide a comprehensive analysis of the specific features of legal terms, identify deficiencies in their translation in normative legal acts, and develop scientifically grounded recommendations for improving the linguistic support of criminal proceedings. The scientific and practical significance of the research lies in the need to ensure uniform interpretation of legal norms in the state language in order to protect the rights of participants in the proceedings. The methodology is based on a systemic approach and includes comparative legal analysis of Kazakh and Russian texts, content analysis of translation studies literature, and examination of official interpretations and legal acts. The findings demonstrate that literal translation of legal concepts often distorts their meaning, creating risks of violating the principle of legality. The study proposes measures for terminology unification to improve legal translation quality, eliminate ambiguity, and enhance law enforcement practices.
