90.As cited in its decision in the Nubian case, the African Committee reiterates that according to the Committee on the Rights of the Child and the Committee on the Elimination of all forms of Discrimination Against Women, a harmful practice should, among other things, constitute a denial of the dignity and/or integrity of the individual and a violation of human rights and fundamental freedoms enshrined in the two Conventions.°° 91.

It is a practice that constitutes a total denial of the dignity and worth of the child. State Parties are under an obligation to take legislative, administrative and any other measure to eliminate harmful practices affecting the welfare, dignity, normal growth and development of the child; this includes eliminating slavery or slavery like practices in all its forms.

The two brothers were enslaved for 11 years without any intervention by the State; their eventual escape from slavery was through their own effort. The Committee hence finds that the failure of the Respondent State to eliminate the practice of slavery and the failure to protect Said and Yarg from this harmful practice is a violation of article 21 of the Charter.
