Abstract
<jats:p>This article provides a comprehensive analysis of the impact of constitutional review on the formation and development of the normative and institutional structure of criminal procedure law. The primary aim of the study is to substantiate the role of recognizing constitutional court decisions as sources of law in strengthening the rule of law, ensuring the supremacy of law, and safeguarding fundamental human rights. The scholarly novelty of the research lies in conceptualizing constitutional review not merely as a formal mechanism for assessing the constitutionality of legal norms, but as a functional institution that actively influences the transformation of legal methodology and judicial practice. The study employs comparative legal analysis, normative-doctrinal methods, and the examination of constitutional court precedents. From a practical perspective, the research focuses on aligning procedural safeguards within criminal proceedings - such as detention, search, the right to defense, and the presumption of innocence - with constitutional principles. The findings demonstrate that constitutional review serves not only as a guarantor of legal stability but also as a dynamic instrument for methodological renewal and institutional legitimacy within the criminal justice system.</jats:p>
