D. Admissibility For a report of a disappearance to be considered admissible by the Working Group, it must originate from the family or friends of the disappeared person. Such reports may also be channelled to the Working Group through representatives of the family, Governments, intergovernmental organizations, humanitarian 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 not a family member, it must be in a position to follow up with the relatives of the disappeared person concerning his or her fate. At the request of the source, and in an effort to protect those submitting a report, their identity is kept confidential. To enable the Governments named in the reports to carry out meaningful investigations, the Working Group provides them with at least a minimum of basic data. In addition, the Working Group constantly urges the sources of reports to furnish as many details as possible on the identity of the disappeared person (even, if available, the identity card number) and the circumstances of the disappearance. The following minimum elements are required: (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. If the disappeared person was last seen in a detention centre, an approximate indication is sufficient; (c) Place of arrest or abduction or where the disappeared person was last seen (at least an indication of the town or village); (d) Parties presumed to have carried out the arrest or abduction or to hold the disappeared person in unacknowledged detention; and (e) Steps taken to determine the fate or whereabouts of the disappeared person, or at least an indication that efforts to use domestic remedies were frustrated or otherwise 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 its direct consent for this case to be submitted to the Working Group on its behalf. 16
