<![CDATA[Abstract: Mental retardation is categorized as People with Mental Problems (ODMK) as referred to in Article 1 number 2 of Law Number 18 of 2014 concerning Mental Health, namely people who have physical, mental, social, developmental, and/or quality of life problems who are at risk of experiencing mental disorders. This thesis aims to analyze how criminal liability is applied to perpetrators of criminal acts of abuse who suffer from mental retardation, as well as to re-analyze the basis for the judge's considerations in issuing a verdict against the perpetrator, by referring to Decision Number 817/Pid.B/2024/PN.Kis. This study uses a normative juridical approach method with a descriptive research type. Data were obtained through literature studies by reviewing statutory regulations, legal literature, and court decision documents. The analysis was carried out qualitatively-descriptively against relevant legal norms and concrete case studies. The results of the study indicate that perpetrators of criminal acts of abuse who suffer from mental retardation cannot be fully held criminally responsible if it is proven that their mental condition affects their ability to understand or control their actions as regulated in Article 44 of the Criminal Code. In Case Number 817/Pid.B/2024/PN.Kis, although the defendant was proven to have committed assault according to Article 351 paragraph (1) of the Criminal Code, ideally the medical evidence process related to the defendant's mental condition would be the main basis in the judge's considerations, as well as trial facts to determine the appropriateness of criminal responsibility for the defendant in accordance with the principles of criminal law and protection for people with mental retardation.
