What is the criminal liability for underage rape victims who had an abortion based on Jambi High Court Verdict No. 6/Pid.Sus-Anak/2018/PT.JMB? Based on the result of the analysis, even though the child is proven to have an abortion the fact that she’s an underage victim of rape, it is necessary to remember that every action that causes a child to conflict with the law is not done alone and therefore did a criminal act because of the influence of coercive power, therefore, the child must be released from all claims. The author argues that criminal liability is carried out to fulfil justice, therefore imprisonment or fines for the criminal act the child performed will not solve the problem, the fact that the legal subject in question is underaged or a minor, the child’s mental health and well-being should be prioritized so the child could return safely to the society.
