The Juvenile Justice (Care and Protection of Children) Bill, 2014 aims to achieve the objectives of the UN Convention on the Rights of the Child. It repeals the 2000 Juvenile Justice Act and addresses children aged 16-18 who are in conflict with the law. The bill establishes Juvenile Justice Boards and Child Welfare Committees to handle cases and protect children. It also creates Children's Courts to try 16-18 year olds accused of heinous crimes. The bill outlines general principles of presumption of innocence, the best interests of the child, and institutionalization as a last resort.
