A/HRC/19/58 Admissibility of cases of enforced or involuntary disappearances 10. Reports of disappearances are considered admissible by the Working Group when they originate from the family or friends of the disappeared person. Such reports may, however, be channelled to the Working Group through representatives of the family, Governments, intergovernmental organizations, non-governmental organizations and other reliable sources. They must be submitted in writing with a clear indication of the identity of the sender; if the source is other than a family member, it must have direct consent of the family to submit the case on its behalf, and it must also be in a position to follow up with the relatives of the disappeared person concerning his or her fate. Elements for admissibility 11. In order to enable Governments to carry out meaningful investigations, the Working Group provides them with information containing at least a minimum of basic data. In addition, the Working Group constantly urges the senders of reports to furnish as many details as possible concerning the identity of the disappeared person and the circumstances of the disappearance. The Working Group requires the following minimum elements: (a) Full name of the disappeared person and, if possible, age, gender, nationality, and occupation or profession; (b) Date of disappearance, i.e. day, month and year of arrest or abduction, or day, month and year when the disappeared person was last seen. When the disappeared person was last seen in a detention centre, an approximate indication is sufficient (for example, March or spring 1990); (c) Place of arrest or abduction, or where the disappeared person was last seen (indication of town or village, at least); (d) Parties, acting on behalf of, or with the support, direct or indirect, consent or acquiescence of the Government, presumed to have carried out the arrest or abduction or to be holding the disappeared person in unacknowledged detention; (e) Steps taken by the family to determine the fate or whereabouts of the disappeared person, or at least an indication that efforts to resort to domestic remedies were frustrated or have otherwise been inconclusive. (f) A case should be submitted to the Working Group by a reliable source, which, if other than a family member, must indicate whether the reported victim's family has given their direct consent that this case be submitted to the Working Group on their behalf. 12. If a case is not admitted, the Working Group sends a response to the source indicating that the information received did not fulfil the established requirements, in order to permit the source to provide all relevant information. Situations of vulnerability 13. With respect to reported cases of disappearances, the Working Group highlights the condition of people in situations of vulnerability, including women, children, the elderly, persons with disabilities, and other vulnerable groups. Pregnancy 14. In the case of the disappearance of a pregnant woman, the child presumed to have been born during the mother’s captivity should be mentioned in the description of the case of the mother. The child would be treated as a separate case when witnesses reported that the mother had actually given birth to a child during detention. 143
