Dejusticia, the Human Corporation Regional Center for Human Rights and Gender Justice, the Women National Network, and the Antigone Corporation for Social Development, Human Rights and International Humanitarian Law, filed a nullity action against the administrative act through which the House of Representatives chose Dr. Volmar Perez as Ombudsman, arguing that the triad formed by the national government did not respect the law of equal participation of women (Law 581 of 2000) which requires that the lists of candidates for positions such as the Ombudsman include at least one woman.
