2 For the purposes of this article, the term “migrant” refers to any person outside the State of which he or she is a national, including refugees, asylum-seekers and people who migrate for economic or work- or climate-related reasons.

A/HRC/30/38, 10 August 2015. The WGEID adopted its report at the beginning of 2017 and submitted it to the 36th Session of the Human Rights Council on 28 September 2017; see WGEID, Report of the Working Group on Enforced or Involuntary Disappearances on Enforced Disappearances in the Context of Migration, UN Doc.

E/CN.4/1492, Annex VIII, paras 1, 2.1, and Annex IX, p. 5. Missing people's families and loved ones might also emigrate for economic reasons (families often suffer socioeconomic hardships following a disappearance; see WGEID, Study on Enforced or Involuntary Disappearances and Economic, Social and Cultural Rights, UN Doc. A/HRC/30/38/Add.5, 2015) or to continue searching for their missing loved one in the country where he or she disappeared. See, for example, UN Doc. E/CN.4/1985/15, para. 135. See also UN Doc.

See also Henckaerts, Jean-Marie and Doswald-Beck, Louise, Customary International Humanitarian Law, Vol. 1: Rules, Cambridge University Press, Cambridge, 2005CrossRefGoogle Scholar (ICRC Customary Law Study), Rule 117: “Each party to the conflict must take all feasible measures to account for persons reported missing as a result of armed conflict and must provide their family members with any information it has on their fate.”

9 International Convention for the Protection of All Persons from Enforced Disappearance, 2716 UNTS 3, 20 December 2006 (entered into force 23 December 2010) (ICPPED), Art. 2. See also the Preamble of the Declaration on the Protection of All Persons from Enforced Disappearance, UN Doc. A/RES/47/133, 18 December 1992. While the International Committee of the Red Cross (ICRC) has a mandate under AP I to assist in tracing people who have gone missing in the context of an international armed conflict (Art. 33, para. 3), it is the WGEID that performs this function in the UN in relation to victims of “enforced or involuntary disappearances”. See UN Commission on Human Rights, Resolution 20 (XXXVI), 29 February 1980. It is worth noting that, for a time, the WGEID excluded cases of disappearances occurring in the context of international armed conflicts from its mandate, but it later lifted this restriction on its methods of work and began to accept such cases. See Human Rights Council, UN Doc. A/HRC/WGEID/102/2, 7 February 2014, and Annex I to the report of the Economic and Social Council adopted on 14 November 2001, UN Doc. E/CN.4/2002/79.

93 It should be noted that “‘[s]muggling of migrants’ shall mean the procurement, in order to obtain, directly or indirectly, a financial or other material benefit, of the illegal entry of a person into a State … of which the person is not a national or a permanent resident” for the purposes of the Protocol against the Smuggling of Migrants by Land, Sea and Air, supplementing the UN Convention against Transnational Organized Crime, UNGA Res. 55/25, Annex III, UN General Assembly Official Records, 55th Session, Supp. No. 49, UN Doc. A/45/49, Vol. 1, 2001. The term “‘[t]rafficking in persons’ shall mean the recruitment, transportation, transfer, harbouring or receipt of persons, by means of the threat or use of force or other forms of coercion, of abduction, of fraud, of deception, of the abuse of power or of a position of vulnerability or of the giving or receiving of payments or benefits to achieve the consent of a person having control over another person, for the purpose of exploitation”. See Protocol to Prevent, Suppress and Punish Trafficking in Persons Especially Women and Children, supplementing the UN Convention against Transnational Organized Crime, UNGA Res. 25, Annex II, UN General Assembly Official Records, 55th Session, Supp. No. 49, UN Doc. A/45/49, Vol. 1, 2001, Art. 3(1). See also Kangaspunta, K. and Guth, A., “Trafficking in Persons: Trends and Patterns”, in Organisation for Economic Cooperation and Development (OECD), Illicit Trade: Converging Criminal Networks, OECD Publishing, Paris, 2016Google Scholar. It should be noted that it is often the case that at some point along the way migrant smuggling turns into migrant trafficking: “What starts out as a simple transaction involving a person seeking the services of a smuggler may end up with the migrant being deceived, coerced or exploited somewhere along the line, given the often unequal power relationships between smugglers and migrants. Therefore a smuggled migrant may quickly and unwillingly become a trafficked person.” See IOM, Migrant Smuggling Data and Research: A Global Review of the Emerging Evidence Base, 2016, p. 6.

107 Enforced disappearance is a continuing crime that ends only when the disappearance itself is resolved – that is, when the victim is located or the State provides a satisfactory explanation as to his or her fate.
