Innovative technologies based on artificial intelligence (AI) are rapidly invading various areas of our lives. Legal practice and litigation are no exception. The use of AI in the judiciary carries several risks but can be an essential tool in achieving sustainable development goals. AI systems can facilitate the monotonous work of lawyers in the study of precedents, bills, and regulations. Nevertheless, AI can significantly contribute to resource savings, the rule of law, fair justice, ensuring equality, and non-discrimination. The authors explore modern approaches to the definition of AI suitable for use in legislation, ways to use AI in legal practice, their potential in sustainable development and associated risks, experience gained by national practices of states and international organisations in this field. The conditions and principles of using AI in the judiciary, which will contribute to sustainable development goals, have been determined.
