The complaint 1. The authors of the initial communication are Myriam Zelaya Dunaway and Juan Zelaya, citizens of the United States of America and of Nicaraguan origin, currently residing in the United States. They submit the communication on behalf and upon the request of their brother, Roberto Zelaya Blanco, a Nicaraguan citizen born in 1935, at the time of submission of the communication detained at the prison of Tipitapa, Nicaragua. The authors allege that their brother has been a victim of violations by Nicaragua of articles 7, 9, 10, 14 and 17 of the International Covenant on Civil and Political Rights. In March 1989, Roberto Zelaya was released from detention on the basis of a governmental pardon, and on 19 June 1992 he confirmed the contents of the communication and joined his sister and brother as co-author. He now resides in the United States together with his wife and son. 3.1 The authors submit that there was no wrongdoing or criminal activity on the part of their brother, and that the accusations formulated against him by the Sandinistas (apología del delito; instigación para delinquir) were purely political. It is claimed that Roberto Zelaya was detained arbitrarily from July 1979 to March 1989, that he was denied a fair hearing before an independent and impartial tribunal, that he was tortured and was subjected to pseudo-medical and pharmacological experiments, to inhuman treatment and death threats while in prison, and that the correspondence between Roberto Zelaya and his family was systematically interfered with by the prison authorities. 3.2 The authors submit that their brother's health, already precarious, deteriorated as a result of his detention. They submit that asthma attacks were treated experimentally with cortisone and other drugs. Finally, other inmates and a prison warder A. V. C. are said to have made death threats against Mr. Zelaya on numerous occasions. The facts as submitted by the authors 2.1 Roberto Zelaya Blanco, an engineer and university professor, was arrested without a warrant on 20 July 1979, the day after the assumption of power by the Sandinista Government. He was tried by a Peoples' Tribunal (Tribunal Especial Primero), on account of his outspoken criticism of the Marxist orientation of the Sandinistas. On 23 February 1980, he was sentenced to 30 years' imprisonment. The Tribunal Especial Primero de Apelación confirmed the sentence on 14 March 1980 without an appeal hearing. The State party's information and the authors' comments thereon 4.1 The State party indicates that Roberto Zelaya Blanco was released from detention pursuant to a presidential pardon of 17 March 1989 (Decreto de Indulto No. 044). 4.2 The authors submit that their brother is currently receiving specialized medical treatment for the ailments developed or aggravated during 10 years of detention, inter alia, asthma and chronic hepatitis. They add that the treatment requires frequent and prolonged hospitalization. 2.2 With respect to the issue of exhaustion of domestic remedies, the authors state that because of the political situation in Nicaragua, they were for a long time unable to identify Nicaraguan lawyers willing to take up their brother's case. Only at the beginning of 1989 did Roberto Zelaya inform his family that a lawyer, J. E. P. B., had indicated his readiness to represent him. The Committee's decision on admissibility 5.1 The Committee ascertained, as it is required to do under article 5, paragraph 2 (a), of the Optional Protocol, that the case was not under examination by another instance of international investigation or settlement. The general investigation, by regional and intergovernmental human rights organizations, of situations affecting a number of individuals, including the author of a communication under the Optional Protocol, does not constitute the "same matter" within the meaning of article 5, paragraph 2 (a). 2.3 It is submitted that several organizations, including the Inter-American Commission on Human Rights, Amnesty International, the International Commission of Jurists and the International Committee of the Red Cross (Nicaraguan Section), were apprised of Mr. Zelaya's fate and visited him in prison. The authors add that they addressed many written complaints about their brother's fate to various Nicaraguan authorities, including President Daniel Ortega and the prison management, but that they did not receive any reply. 5.2 The Committee interpreted the State party's general submission that Mr. Zelaya Blanco had been released from detention as implying that he had been offered an appropriate remedy. However, the Committee reiterated its position that it is implicit in rule 91 of the rules of procedure and article 4, paragraph 2, of the Optional Protocol, that a State party to the Covenant should make available to the Committee all the information at its disposal; this 2.4 Upon his release in March 1989, Mr. Zelaya was allegedly threatened by a prison guard, "Comandante Pedro", with the words "Be very careful. If you dare write or speak against the Sandinistas, you will regret it." 31
