entitled to adequate compensation from the State party. He submits that following his release from the first period of detention he continued to be harassed and intimidated by the authorities; he claims that he denounced these practices. retaliation for the propagation of his opinions and his activism, the authorities subjected him to threats and intimidation, and that in January 1986 he was dismissed from his employment. The Ndola City Council subsequently expelled him and his family from their home, while the payment of his father's pension was suspended indefinitely. 3.3 The author states that, as a political activist and former prisoner of conscience, he has been placed under strict surveillance by the authorities, and that he continues to be subjected to restrictions on his freedom of movement. He claims that he has been denied a passport as well as any means of making a decent living. 2.2 Because of the harassment and hardship to which he and his family were being subjected, the author emigrated to Namibia, where other Zambian citizens had settled. Upon his return to Zambia, however, he was arrested and placed in custody; the author's account in this respect is unclear and the date of his return to Zambia remains unspecified. Issues and proceedings before the Committee 2.3 The author notes that by September 1988 he had been detained for 31 months, on charges of belonging to the People's Redemption Organization – an association considered illegal under the terms of the country's one-party Constitution – and for having conspired to overthrow the Government of the then President Kenneth Kaunda. On an unspecified subsequent date, he was released; again, the circumstances of his release remain unknown. At an unspecified later date, Mr. Bwalya returned to Zambia. 4.1 Before considering any claims contained in a communication, the Human Rights Committee must, in accordance with rule 87 of its rules of procedure, decide whether or not it is admissible under the Optional Protocol to the Covenant. 4.2 During its forty-first session, the Committee considered the admissibility of the communication. It noted with concern the absence of cooperation from the State party which, in spite of four reminders addressed to it, had failed to comment on the admissibility of the communication. It further noted that the author's claim that the Supreme Court had dismissed his appeal had remained uncontested. In the circumstances, the Committee concluded that the requirements of article 5, paragraph 2 (b), of the Optional Protocol had been met. 2.4 On 25 March 1990, the author sought the Committee's direct intercession in connection with alleged discrimination, denial of employment and refusal of a passport. By letter of 5 July 1990, the author's wife indicated that her husband had been rearrested on 1 July 1990 and taken to the Central Police Station in Ndola, where he was reportedly kept for two days. Subsequently, he was transferred to Kansenshi prison in Ndola; the author's wife claims that she was not informed of the reasons for her husband's arrest and detention. 4.3 As to the claims relating to articles 7 and 10 of the Covenant, the Committee considered that the author had failed to substantiate his claim, for purposes of admissibility, that he had been subjected to treatment in violation of these provisions. Accordingly, the Committee found this part of the communication inadmissible under article 2 of the Optional Protocol. 2.5 With respect to the requirement of exhaustion of domestic remedies, the author notes that he instituted proceedings against the authorities after his initial arrest. He notes that the district tribunal reviewing his case confirmed, on 17 August 1987, that he was no danger to national security but that, notwithstanding the court's finding, he remained in custody. A further approach to the Supreme Court met with no success. 3.1 In his initial submissions, the author invokes a large number of provisions of the Covenant, without substantiating his allegations. In subsequent letters, he confines his claims to alleged violations of articles 1, 2, 3, 9, 10, 12, 25 and 26 of the Covenant. 4.4 With respect to the author's claims that he: (a) had been subjected to arbitrary arrest and unlawful detention; (b) had been denied the right to liberty of movement and arbitrarily denied a passport; (c) had been denied the right to take part in the conduct of public affairs; and (d) had been discriminated against on account of political opinion, the Committee considered that they had been substantiated, for purposes of admissibility. Furthermore, the Committee was of the opinion that, although articles 9, paragraph 2, and 19 had not been invoked, the facts as submitted might raise issues under these provisions. 3.2 The author contends that, since he never participated in any conspiracy to overthrow the Government of President Kaunda, his arrests were arbitrary and his detentions unlawful, and that he is 4.5 On 21 March 1991, the Committee declared the communication admissible in so far as it appeared to raise issues under articles 9, 12, 19, 25 and 26 of the Covenant.
