7 procedure, States parties are requested to inform the relevant committee on measures taken to implement the committee’s recommendations in individual cases where the committee has found that the State party was in breach of its treaty obligations. It should also be noted that OHCHR and other United Nations entities follow up through technical assistance and advocacy. Follow-up in this sense is separate from the committees’ followup procedures; it comes under the general role of technical assistance of the United Nations. ✔✔ General comments. All treaty bodies prepare general comments— sometimes referred to as general recommendations5—to elaborate the meaning of specific provisions or themes in treaties, with a view to assisting States parties to implement them and strengthening the enjoyment of specific rights by rights holders. ✔✔ Request for studies of the Secretary-General. The Convention on the Rights of the Child stipulates that its Committee may recommend that the General Assembly request the Secretary-General to undertake on its behalf studies on specific issues relating to the rights of the child (art. 45 (c)). Two such studies have been undertaken so far: one on the impact of armed conflict on children (1996) and another on violence against children (2006). These two studies have led to the establishment of Special Representatives of the Secretary-General for these two issues. ✔✔ Address the General Assembly. If the Committee on Enforced Disappearances receives information which appears to it to contain well-founded indications that enforced disappearance is being practised on a widespread or systematic basis in a territory under the jurisdiction of a State party, the Committee may, after seeking from the State party concerned all relevant information on the situation, urgently bring the matter to the attention of the General Assembly of the United Nations, through the Secretary-General. 5  ommittee on the Elimination of Racial Discrimination and Committee on the Elimination of Discrimination against C Women.
