Shortly after the report by Félix Ermacora, the UN Commission on Human Rights considered one of the proposals made and decided on 29 February 1980 to set up the Working Group on Enforced or Involuntary Disappearances, the first of the so-called thematic mechanisms of the commission and the most important body of the United Nations that has since been dealing with the problem of disappearances in cases that can be attributed to governments, as well as issuing recommendations to the commission and governments on the improvement of the protection afforded to missing persons and their families and to prevent cases of enforced disappearance. Since then, different causes began to be developed in various international legal bodies, whose sentences served to establish a specific jurisprudence on enforced disappearance.
