This article provides a comprehensive analysis of the conceptual and legal classification of corruption-related crimes from theoretical, comparative, and practical perspectives. The author highlights the lack of a precise legal definition for the terms “corruption” and “corruption-related crime” in Uzbekistan’s legislation, which creates difficulties in proper legal qualification. International legal frameworks, including the UN Convention Against Corruption, the Council of Europe’s conventions, and CIS model laws, are examined alongside national legislation of countries such as Italy and Tajikistan. The article identifies key elements of corruption offenses, emphasizing the role of official position, motive of personal gain, and direct intent. A multi-level classification is proposed based on the offender’s legal status, affected object, and degree of social harm. The paper also addresses contemporary manifestations of corruption, such as lobbying, protectionism, nepotism, and misuse of public resources. It argues for the urgent development of a unified classification system and legal recognition of corruption offenses within the structure of the Uzbek Criminal Code, based on the principle of direct object interference.
