them. The State also has basic obligations to satisfy essential rights that are not subject to progressive realization but are of immediate effect.79 58. In addition, the IACHR considers that in light of the duty to ensure rights established in Article 1(1) of the American Convention and the interpretation of that provision by the organs of the Inter-American system, states parties have a duty to take reasonable steps to prevent the infringement of the rights contained in Article 26 in the context of business activities. The foregoing includes adopting a legal framework that assures protection for those rights and provides effective access to remedies for victims of such violations. Among the measures for ensuring an adequate legal framework, the State should require business entities under its jurisdiction to exercise human rights due diligence in order to identify, prevent and mitigate the risks of violations of rights in the context of their activities.80 59. Finally, the organs of the Inter-American system have stressed the duty of states to adopt measures to ensure real equality among people and combat historical or de facto discrimination against a variety of social groups. The Commission has indicated that the implementation of positive measures is necessary to ensure that people linked to groups that suffer structural inequalities or have been victims of historical exclusion can exercise their rights.81 In the same vein, the Court has written that States are obliged “to adopt positive measures to reverse or change discriminatory situations that exist in their societies and that prejudice a specific group of people. This includes the special obligation of protection that the State must exercise with regard to acts and practices of third parties who, with its tolerance or acquiescence, create, maintain or promote discriminatory situations.”82 60. In applying the above parameters to the instant case, the Commission notes, to begin with, that Article 45 of the Charter of the OAS references the rights to health and social security: Article 34(i) of that instrument also highlights the role of the state in the “[p]rotection of man's potential through the extension and application of modern medical science,” emphasizing the importance of the guarantee of health to an individual's integral development. Articles XI of the American Declaration and 12 of the ICESCR also recognize that right. As for the right to social security, that derives from Article 45, paragraphs (b) and (h) of the OAS Charter, which respectively establish the right to protection against unexpected or social risks in relation to work and to development of an efficient social security policy. In turn, more broadly, Article 46 refers to the task of harmonizing standards on social security at the regional level. For its part, the American Declaration enshrines that same right at its Article XVI, as does the ICESCR, at Article 9. As the Commission has noted, it may be necessary to resort to other international instruments to show the derivation of a right based on a public policy measure or objective included in an economic, social, cultural, educational, or scientific provision contained in the Charter of the OAS.83 61. Based on the above, the Commission considers that the rights to health and social security are among the economic and social standards mentioned in Article 26 of the American Convention and, therefore, states parties are under the obligation to seek their progressive development and to respect, ensure, and adopt the necessary measures for the realization of those rights. 79.
