a) As of October 19, 2001, the installations of the PRODH Center have been guarded and offered security; to this end, a PGJDF patrol car was installed in front of these offices and, as of October 20, 2001, the PGJDF have provided security personnel to the lawyer, Pilar Noriega García, during 24-hours each day. b) With regard to the measures proposed by the beneficiaries that are pending implementation, the PRODH Center requested that 31 cellular telephones should be put in service for the use of its members in case of dangerous situations or fear of attack. Bárbara Zamora López requested the State to provide the following protection measures: installation of a closed circuit system in the Colectivo Tierra y Libertad law office similar to the one installed in the PRODH Center and placing a guard in front of that law office from 7 a.m. to 10 p.m. Lastly, as protection measures, Leonel Rivero Rodríguez requested that he be provided with a car and two private guards of his own choice; and c) The investigation into the facts related to the death of Digna Ochoa y Plácido has not been undertaken, despite the statements of several authorities. Digna Ochoa’s next of kin and the PRODH Center have collaborated with the Office of the Attorney General in the criminal proceedings to investigate her death. However, they have not had full access to the file, and this has prevented substantive collaboration. As a result of the death of Digna Ochoa y Plácido, the Court was also requested in this document with observations, to expand the provisional measures to include her parents and twelve siblings, because Mrs. Ochoa’s next of kin have seen strange cars and persons around their houses and received anonymous telephone calls which cause them to fear for their lives and personal safety. Finally, in this brief with observations, the Court was requested to proceed as follows: […] 4. To call on the State of Mexico to comply immediately with the personal protection measures requested in favor of the persons who are still without protection. 5. To call on the State of Mexico to duly adopt the necessary or corrective measures to ensure the effectiveness of the investigation into the facts of the assassination of the lawyer Ochoa, and the threats against the members of the [PRODH] Center and Leonel Rivero. 6. The public hearing on this request for provisional measures was held at the seat of the Court on November 26, 2001. There appeared at the hearing: For the State of Mexico: Mariclaire Acosta Urquidi, Under-Secretary for Human Rights and Democracy Carlos Pujalte Piñeiro, Mexican Ambassador to Costa Rica
