Abstract

The disappearance of migrants, which has reached preoccupying high numbers in recent decades, is related both to the particular vulnerability of migrants traversing dangerous migratory routes and to the high degree of impunity that characterizes investigation and search efforts required. This article argues that the disappearance of migrants at the hands of non-state actors in contexts of systematic impunity and in situations where the state had knowledge or should have had knowledge of a serious risk of such disappearance, but failed to act to prevent it, can be considered to have occurred with the acquiescence of the state. Thus, given that all further elements of the definition of enforced disappearance have been satisfied, this factual situation qualifies as an “enforced disappearance” for the purposes of international human rights law. Key to this demonstration is the concept of knowledge, which is an essential component of acquiescence. This article not only addresses the normative framework of acquiescence and its interpretation by international and regional human rights bodies, including how it relies on the element of state knowledge, but it also examines the extent to which this factor is critical to understanding states’ due diligence obligations to prevent, investigate, and sanction human rights obligations, including disappearances. In order to better understand the factors that should be taken into consideration while assessing a state‘s knowledge of migrant disappearances, including in the context of systematic impunity, it is then suggested to borrow from the international criminal law test related to the concept of “constructive knowledge” and to the doctrine of command responsibility. These considerations should inform a test for assessing whether disappearances of migrants occurring in contexts of systematic impunity can be considered as having been known by the state and as having occurred with its acquiescence and, thus, as constituting “enforced disappearances” under international human rights law.

Résumé

Résumé

Les disparitions de migrants ont atteint des chiffres très préoccupants au cours des dernières décennies et sont liées à la fois à la vulnérabilité particulière des migrants, aux routes migratoires dangereuses qu’ils empruntent et au degré élevé d’impunité qui caractérise les efforts d’enquête et de recherche requis. Cet article soutient que la disparition de migrants aux mains d’acteurs non étatiques dans des contextes d’impunité systématique et dans des situations où l’État avait connaissance ou aurait dû avoir connaissance d’un risque sérieux de disparition, mais n’a pas agi pour l’empêcher, peut être considérée comme s’étant produite avecl’acquiescement de l’État. Ainsi, advenant que tous les autres éléments de la définition de la disparition forcée sont présents, cette situation factuelle devrait pouvoir être qualifiée de “disparition forcée” au sens du droit international des droits de la personne. La clé de cette démonstration repose sur le concept de connaissance, qui est une composante essentielle de l’acquiescement. Cet article aborde non seulement le cadre normatif de l’acquiescement et son interprétation par les organismes internationaux et régionaux de protection des droits humains, y compris la manière dont cette notion s’appuie sur l’élément de connaissance de l’État, mais il examine également dans quelle mesure ce facteur est essentiel pour comprendre les obligations de diligence raisonnable qu’ont États pour prévenir, enquêter et sanctionner les violations des droits humains, y compris les disparitions. Afin de mieux comprendre les facteurs qui devraient être pris en considération lors de l’évaluation de la connaissance qu’a un État des disparitions de migrants, y compris dans un contexte d’impunité systématique, il est suggéré de s’inspirer du critère de droit pénal international lié au concept de “connaissance” et à la doctrine de la responsabilité des commandants. Ces considérations devraient éclairer un test permettant d’évaluer si les disparitions de migrants survenant dans des contextes d’impunité systématique peuvent être considérées comme ayant été connues de l’État et comme s’étant produites avec son acquiescement, constituant ainsi des “disparitions forcées” au sens du droit international des droits de la personne.

87 This standard is particularly developed in relation to the non-refoulement principle in migration contexts. For asylum and removal procedures, the refugee definition has long been interpreted to cover harms inflicted by private groups or individuals that a country’s government is unable or unwilling to control. In this context, acquiescence of a public official requires that the public official, prior to the activity constituting torture, has awareness of such activity and thereafter breaches their legal responsibility to intervene to prevent such activity. The presence of “acquiescence” as an attribution element in the CAT definition of torture therefore opens the possibility of its interpretation in the context of due diligence. CAT, supra note 76.

Therefore, the police were not considered to have failed to carry out its positive obligation to take preventive operational measures to protect individual whose life at risk from criminal acts of another individual.

277 “In addition to other grounds of criminal responsibility under this Statute for crimes within the jurisdiction of the Court: 1. A military commander or person effectively acting as a military commander shall be criminally responsible for crimes within the jurisdiction of the Court committed by forces under his or her effective command and control, or effective authority and control as the case may be, as a result of his or her failure to exercise control properly over such forces, where: (a) That military commander or person either knew or, owing to the circumstances at the time, should have known that the forces were committing or about to commit such crimes; and (b) That military commander or person failed to take all necessary and reasonable measures within his or her power to prevent or repress their commission or to submit the matter to the competent authorities for investigation and prosecution. 2. With respect to superior and subordinate relationships not described in paragraph 1, a superior shall be criminally responsible for crimes within the jurisdiction of the Court committed by subordinates under his or her effective authority and control, as a result of his or her failure to exercise control properly over such subordinates, where: (a) The superior either knew, or consciously disregarded information which clearly indicated, that the subordinates were committing or about to commit such crimes; (b) The crimes concerned activities that were within the effective responsibility and control of the superior; and (c) The superior failed to take all necessary and reasonable measures within his or her power to prevent or repress their commission or to submit the matter to the competent authorities for investigation and prosecution.”

279 “1. Each State Party shall take the necessary measures to hold criminally responsible at least: (a) Any person who commits, orders, solicits or induces the commission of, attempts to commit, is an accomplice to or participates in an enforced disappearance; (b) A superior who: (i) Knew, or consciously disregarded information which clearly indicated, that subordinates under his or her effective authority and control were committing or about to commit a crime of enforced disappearance; (ii) Exercised effective responsibility for and control over activities which were concerned with the crime of enforced disappearance; and (iii) Failed to take all necessary and reasonable measures within his or her power to prevent or repress the commission of an enforced disappearance or to submit the matter to the competent authorities for investigation and prosecution; (c) Subparagraph (b) above is without prejudice to the higher standards of responsibility applicable under relevant international law to a military commander or to a person effectively acting as a military commander. 2. No order or instruction from any public authority, civilian, military or other, may be invoked to justify an offence of enforced disappearance.”
