determine whether their situation of risk persists, before requesting the lifting of the measures. 30. In particular, in relation to the situation of Luis Guillermo Perez, the Court observes that the State is providing him with protection under the precautionary measures ordered by the Inter-American Commission in favor of the members of the Colectivo de Abogados Jose Alvear Restrepo. Even though a high-ranking Army officer who has been sentenced for the facts of the Mapiripán massacre alluded directly to Mr. Perez, which could indicate a current risk,16 it appears that this was related to his work in the above-mentioned organization whose members are beneficiaries of precautionary measures. Hence, it is not appropriate to maintain these provisional measures in his favor, without prejudice to what the Commission considers pertinent in this regard. 31. The Court observes that, although a reasonable time has elapsed and despite the Court’s request (supra having seen paragraph 7), neither the State nor the representatives have provided sufficient information to allow the Court to assess the real actual situation of risk faced by each of the beneficiaries and their family. Moreover, considering the situation of risk experienced by the beneficiaries, particularly owing to their internal forced displacement, it is probable that they have preferred not to provide information for fear of suffering another attack.17 However, the useful effect of the provisional measures depends on the real possibility that they can be implemented.18 Consequently, if there is a lack of information regarding the situation of risk over an extended period of time, the protective measures become illusory. In this case, the limited information provided has given rise to a situation of uncertainty at certain times, which is incompatible with the preventive and protective nature of the provisional measures and, therefore, makes it difficult to monitor their implementation. Most of the beneficiaries of the measures have not even agreed to provide their contact information so that their specific needs of protection can be determined. Hence, the provisional measures have had no effect in actual fact and, consequently, it is appropriate to order that they be lifted. 32. Lastly, the Court reiterates that Article 1(1) of the Convention establishes the general obligations of the State Parties to respect the rights and freedoms recognized therein and to ensure to all persons subject to their jurisdiction the free and full exercise of those rights and freedoms, under all circumstances. For their part, provisional measures are exceptional in nature and are complementary to this general obligation of the States. In this regard, the Court’s presumptions in order to lift the provisional measures cannot signify that the State is relieved of its convention-based protection obligations. Therefore, the Court emphasizes that, irrespective of the existence of specific provisional measures, the State has a special obligation to ensure the rights of those individuals in a situation of risk, particularly of Carmen Johana Jaramillo Giraldo, Esther Pinzón López, Sara Paola Pinzón López, María Teresa Pinzón López, Yur Mary Herrera Contreras, Zully Herrera Contreras, Maryuri Caicedo 16 The letter indicated in the representatives’ brief has not been submitted to the Court; and no other probative elements have been submitted so that it can verify its existence. 17 Case of Clemente Teherán.
