General Comment No. 4: Adolescent health and development in the context of the Convention on the Rights of the Child, CRC/GC/2003/4, July 1, 2003
The right to non-discrimination
6. States parties have the obligation to ensure that all human beings below 18 enjoy all the rights set forth in the Convention without discrimination (art. 2), including with regard to “race, colour, sex, language, religion, political or other opinion, national, ethnic or social origin, property, disability, birth or other status”. These grounds also cover adolescents’ sexual orientation and health status (including HIV/AIDS and mental health). Adolescents who are subject to discrimination are more vulnerable to abuse, other types of violence and exploitation, and their health and development are put at greater risk. They are therefore entitled to special attention and protection from all segments of society.
