As a member of the modern world, Nigeria like other African Countries has endorsed the United Nations Convention on the Right of the Child. By its participation, the convention became part of our laws. Even before these United Nation Convention we had several statutes which dealt with the rights of a child but not specifically those of adolescents. Since the adolescence is in that transitionary stage in life between childhood and adulthood no special legislation is made to protect their rights. The law which would be applicable to the adolescent within our criminal justice system would depend on the age of that adolescent. His/her age would determine the enforcement of the violation of these rights. Taking into account our various legislation, for this article, an adolescent would be a person between the ages of twelve (12) and twenty one (21) years. The aim of the article is to identify some aspects of adolescent rights and assess the effectiveness of the various laws which are applicable to adolescents in Nigeria and examine whether or not these laws actually enforce the adolescent's rights.
