Externalization of Border Controls as a Violation of Human Rights of Irregular Migrant Children: A Global Dilemma

Various States have resorted to stringent border controls as irregular migrants sought to enter their territories within the past few years. These externalised border controls are sometimes, strictly enforced to the extent that irregular migrants—particularly vulnerable migrants such as unaccompanied minor children are arbitrarily detained in detention centres—the living conditions of which are in express violation of various international human rights treaties. This article examines the validity of these border controls which continue to negate the human rights of these irregular migrant children, and the role which the international community plays in upholding these established human rights The article discusses the extent to which these externalized border controls are enforced in Australia and across the European Union in law and in practice. The article concludes by proffering recommendations which facilitate a global harmonised governance system for irregular migrant children.


Introduction
In recent times, countries that play host to irregular migrants have been concentrating their efforts and resources on attempts to halt the flow of irregular migration 1 . Irregular migration is carrying an increasing number of people across international boundaries, putting a strain on immigration and citizenship policies in countries around the world. Further complicating the issue is the realisa-1 tion that irregular migration involves more than just the individuals who choose or are forced to enter into or remain in a country irregularly. Thus, the future of the children of these individuals, who enter into and remain in the receiving State by force or irregularly, is uncertain 2 (Van Waas, 2007). Although family separations have been common among almost all migrants at various historical periods, immigration regimes today (in the legislative and enforcement sides) keep families separated for longer and more uncertain periods of time. These longer and more uncertain separations have prompted an increase in the migration of unaccompanied children to reunite in receiving countries 3 (Menjivar, 2006).
However, the subject of international debate in recent years is legality of externalization policies of receiving countries/destination states and the ways in which these policies negate the human rights of irregular migrant children.
While states' sovereign power is not without limitations, including those imposed by international human rights law, migrants in an irregular situation find themselves in a legal vacuum, as the tension between these two structures remains unresolved 4 (Cassese, 2001).
The precariousness of being undocumented arises from the particular role ascribed to States themselves as guardians or protectors of human rights and from a tendency to confine certain rights within a context of community or citizenship (Goodwin-Gill, 1989) 5 . Bhabha observes that a large number of children could be said to be functionally stateless, whether or not they have a legal nationality. Despite not being stateless according to the current legal definition of the term 6 , the fact that they do not have the citizenship of the state they reside in places them in a particular legal void, an ambiguous position between inalienable and unenforceable rights 7 (Bhabha, 2009). This condition of statelessness of children appears to entail a loss of the "right to have rights" or the person's recognition, by others, as a member of a given community.
Within the past few years, the detention of irregular migrants and accompanying children as a form of control by destination States to control who enters or remains within their territories has been a major course of concern. Whilst the act of detention is not a crime in itself, it is the treatment of children and their families in such a manner that it emphasizes their statelessness and the infringe-2 Van Waas, ibid.

This article examines the role of the international community in enforcing the rights of irregular migrant children in the 21 st century. Part 1 provides a background and introduction to the paper. Part 2 discusses the factors which necessitate international migration and the roles of states in adopting externalization policies to curtail irregular migrant children. Part 3 provides an expose on the protections afforded by irregular migrant children under existing international human rights instruments. Part 4 analyses the legality of externalization policies in specific jurisdictions and how these policies provide effective protection of the rights of irregular migrant children. Part 5 discusses the role of the European Court of Human Rights regarding enforcement of the rights of irregular migrant children. Part 6 proffers recommendations towards protection of the human rights of irregular migrant children Part 7 concludes the paper. This article utilises a socio-legal approach in its analysis, with reference to documents which employed credible qualitative and quantitative data, in order to provide a detailed overview of the topic.

International Migration and Externalization Policies
An undocumented or irregular migrant is described by the 1990 International Convention on the Protection of the Rights of All Migrant Workers and Members of their Families as any person without a permit authorising them to enter, to stay or to engage in a remunerated activity in the State of destination pursuant to the law of that State and to international agreements to which it is a Party 8 (UN Committee, 2012).
Migration across borders is an archetypical transnational phenomenon 9 (Estrada-Tanck, 2013). The causes of migration are complex and myriad and result in no small measure from the phenomenon of globalization in the economic, political and cultural spheres. Factors including demographic and skills deficits in much of the industrialised world, insufficient employment, armed conflicts, etc. indicate that migration is both necessary and here to stay 10 (Fraser & Konigs, 2012 the responsibility for providing international protection to refugees and asylum-seekers to other countries, or the enlistment of source or transit countries to tighten control over their borders. Such externalization policies of destination state include "push-backs" by land or sea, involving automatically pushing back people who are attempting to cross a border towards a country from which they came. They are unlawful because they take place without procedural safeguards and without respecting the right of individuals to challenge their expulsion or apply for asylum. Transit states also have pushbacks and "pull-backs" i.e. preventing people from leaving. These are also unlawful because they take place without procedural safeguards and without respecting the right of individuals to leave any country, including their own 12 (Amnesty International, 2017).
Accordingly, these externalizations may actually trigger, directly or indirectly, one or more categories of rights violations. Regardless of their status or location, migrants have a range of fundamental rights that can be implicated by migration-control externalization practices and which protect migrants against abuse throughout the migration process 13 (Frelick, Kysel, & Podkul, 2016). The extent of the implication of these externalization practices on the fundamental rights of irregular migrant children is what this article focuses on.
Migrating children and youth-whether between or within countries and whether accompanied by their relatives or not-have become a recognised part of today's global and mixed migration flows 14 (Fraser & Konigs, 2012). Children can migrate in various ways. Children move across borders with their parents or are accompanied by extended family members or other adults and within mixed migratory flows. Children are also increasingly seeking migration opportunities to move across borders autonomously and unaccompanied. Falling prey to transnational organized crime and exploitation practices including smuggling, trafficking in persons and contemporary forms of slavery, which are described as abusive forms of migration, may also be a part of the migration experience for many children. Migration potentially enhances the child's opportunities and future choices.
However, many forms of migration, like the treatment of children during the migration process, can also pose serious threats to the child's rights. The transnational nature of migration however poses a problem as to the best way to meet the human rights obligations of such migrant persons based on the universal paradigm guiding human rights principles. This principle holds that all persons are equal in dignity and rights and should therefore not be discriminated against on the basis of culture, language, ethnicity or national rights among other attributes. However, the universality of human rights may be doubtful when applied to the case of migrant children 16 (Estrada-Tanck, 2013). Thus, the role of international human rights law is examined to determine the extent to which it contributes to the protection of irregular migrant children.

International Human Rights Instruments and Protection of Irregular Migrants, including Children
The rights of all migrants receive comprehensive elaboration and thus, protection only indirectly-by application of general human rights treaties (which recognize that all human beings have rights) or by virtue of treaties which protect sub-groups of migrants, such as refugees or migrant laborers 17 (Kysel, 2016).
Human rights law asserts equality of treatment between citizens and non-citizens in accordance with the national standard 18 (Chetail, 2013).
Amador aptly states: … International law today recognizes that individuals and other subjects are directly entitled to international rights just as it places upon them certain international obligations … the basis of this new principle would be the "universal respect for, and observance of, human rights and fundamental freedoms" referred to in the Charter of the United Nations and in other general, regional and bilateral instruments. The object of the "internationalization" … of these rights and freedoms is to ensure the protection of the legitimate interests of the human person, irrespective of his nationality. Whether the person concerned is a citizen or an alien is then immaterial: human beings, as such, are under the direct protection of international law. (Amador, 1956)   From a general international law perspective, the rights of non-citizens have bee (re)discovered quite recently as a side effect of the normative expansion of the international human rights law. The Universal Declaration of Human Rights, the UN International Covenant on Civil and Political Rights (ICCPR) and the UN International Covenant on Economic and Social Rights proclaim in their preamble "the recognition of the inherent dignity and of the equal and inalienable rights of all members of the human family 20 (ICCPR & ICESR, 1966). The United Nations General Assembly adopted in December 1985, the Declaration on the Human Rights of Individuals who are not Nationals of the Country in which they live 21 (UN Resolution, 1985). Indeed, the ICESR contains specific provisions regarding the state obligation to reduce infant mortality and ensure healthy child development 22 (ICESR, 1966); protection of children from economic and social exploitation 23 and the right to education 24 . In 1990, the UN adopted a specific convention on migrant workers i.e. the International Convention on the Protection of the Rights of all Migrant Workers and Members of their Families (ICRMW) 25 . The ICRMW applies during the entire migration process of migrant workers and members of their families, which comprises preparation for migration, departure, transit and the entire period of stay and remunerated activity in the State of employment… 26 The ICRMW obligates States Parties to pay particular attention to the problems that may be posed to minor children by the deprivation of a migrant worker's liberty 27 . The Convention also addresses the basic rights of all migrant workers to "access … education on the basis of equality of treatment with nationals of the State concerned" with "access to public pre-school educational institutions or schools … not [to] be refused or limited by reason of the irregular situation with respect to stay of employment of either parent or by reason of the irregularity of the child's stay in the State of employment" 28 . Although these provisions obligate State Parties to facilitate the attainment of these rights, the Convention envisages such facilitation where either parent of the child is a legal migrant worker, and not in circumstances where the migrant is illegal/irregular/undocumented. As such, the Convention caters mainly for migrant workers and is not applicable to "refugees and stateless persons, unless such application is provided for in the relevant national legislation of or international instruments in force for, the State Party concerned" 29 (ICRMW, 1990). This clause already disqualifies irregular migrants and their children from the benefits accorded to regular migrant workers under the Convention. The low rate of ratification of this Convention speaks to the fact that the international community is not satisfied with the inadequate protection afforded migrants under this treaty and the protection of irregular migrant children. Currently, there appears to be no single international instrument that clearly and explicitly enshrines the protection of a core baseline of rights (and corresponding set of minimum state obligations) and applies to all migrants regardless of the cause of their migration 30 (Kysel, 2016).
However, with respect to the express protection of the rights of migrant children, the Convention on the Rights of the Child (CRC) 2003 is mostly relied on in international law. Article 2 of the CRC obligates State Parties to respect and ensure the rights of each child within their jurisdiction without discrimination of any kind, irrespective of the child's or his/her parents race, colour, sex, nationality or other status. Accordingly, State Parties are to take all appropriate measures to ensure that the child is protected against all forms of discrimination or punishment on the basis of the status, activities, expressed opinions or beliefs of the child's parents, legal guardians or family members (Child Rights Act) 31 . Whilst these provisions provide a footing for irregular migrant children, certain questions arise from these provisions of the CRC in relation to the human rights of irregular migrant children. Noll puts forward the argument that if undocumented/irregular migrants are physically present in the territory of a destination state, they come under its jurisdiction and their jurisdictional presence triggers human rights obligations. However, what is that State obliged to do or not do in relation to such a migrant, particularly where such a person is not yet a member of the political community? 32 (Noll, 2010). This quandary arising from the failure of existing international instruments to provide an over-arching instrument protecting the human rights of irregular migrants and their children has led to constant violations of human rights of these categories of persons by States exercising their sovereign power to protect its borders from them. These externalization policies, specifically the detention of migrant children, emphasize the degradation of the human rights of these migrant children. The International Organisation on Migration (IOM) defines detention of migrants, whether criminal or administrative, as the "restriction on freedom of movement through confinement that is ordered by an administrative or judicial authority" 33 (IOM, 2011). The sub-29 Article 3 (d), ICRMW. sequent parts of this paper examines the veracity of this statement, the role of international law as a blanket to cushion the effects of these policies imposed by States and the role of States in restricting or promoting these freedoms.

Externalization Policies: Eroding the Human Rights of Migrant Children or an Enforcement of Sovereign Rights of States?
Scenes of irregular migrants stranded at the southern borders of the European Union (EU) and the United States (US) have permeated social media in the last few years 34 (Johnson, 2015). Whilst States are within their rights to adopt externalized border controls which allow governments to detain non-citizens for migration-related reasons, concerns have been raised regarding the arbitrary and unlawful detention of these irregular migrants in overcrowded and unhygienic conditions falling below international standards, some of which amount to human rights violations 35 (Mossou, 2017). Of particular concern is the exposure of children as an extremely vulnerable group, to detention and its harmful consequences 36 (Mossou, 2017), particularly where they are unaccompanied 37 (Parkin, 2015). This part of the article discusses incidents of arbitrary detention in Australia and across Europe, and how the courts and international law have addressed these human rights violations. It is important to note that this paper considers these two continents to highlight the marked differences in their legal and political approaches to detention of irregular migrant children.

Detention of Irregular Migrant Children in Australia
This article discusses the Australian system of detention because of the controversy which has trailed this jurisdiction and its immigration policies within the past few years. Australia's system of mandatory immigration detention was introduced by the Labor Government in 1992. Its Migration Act refers to unlawful non-citizens as people who have arrived in Australia without a visa or have arrived in Australia with a visa that has later expired. If unlawful non-citizens arrive in Australia by sea, they are referred to as "unauthorised maritime arrivals".  Mossou,ibid. 37 For example, in 2014, half of the child migrants entering Italy were unaccompanied, and as at 2015, two-thirds of child migrants entering the EU were unaccompanied. Parkin, Gemma (2015). The EU can no longer stand by while child migrants are drowning. The Guardian, April 21; Johnson (n 34) IV. 38 The Forgotten Children-National Inquiry into Children in Immigration Detention (2014). Australian Human Rights Commission: Sydney, 24. migrants on arrival in Australia and transfer children who are unauthorised maritime arrivals to a Regional Processing Country. Officers are required by the Migration Act to carry out these tasks, regardless of whether it would be in the child's best interests 39 (Australian Human Rights Commission, 2014). Despite the fact that section 4AA of the Migration Act explicitly stating that "a minor shall only be detained as a measure of last resort", the detention of migrant children is the first action of the Australian government. These are in outright disregard of the provisions of the Convention on the Rights of the Child which provides that "if detention of children is necessary in order to achieve a particular aim, then the length of detention should be the shortest appropriate period for the achievement of that aim". The Convention also requires that "children in detention should be treated with humanity and respect" and "should not suffer torture or cruel, inhuman or degrading treatment or punishment".

Australian detention centres for irregular migrants in Nauru and Christmas
Island are cramped enabling rapid spread of infections. The children and their families live in converted shipping containers, the majority of which are 3 × 2.5 metres. Children are effectively confined to these rooms for many hours of the day as they are the only private spaces which provide respite from the heat.

Detention of Irregular Migrant Children in Europe
Immigration of children is also a growing phenomenon in Council of Europe member states 46 (Parliamentary Assembly, 2014). The Council of Europe has recognized that many Member States are working to end detention of child migrants. For example, in Hungary, detention of migrant children is prohibited 47 .
With the assistance of local non-governmental organizations, the government established a shelter for unaccompanied children 48 (Parliamentary Assembly, 2014).
In Sweden, asylum seekers are registered upon arrival and after being issued an identity card and having spent about a week in transit they are moved into a reception programme. The authorities accommodate those who do not have their own funds to cover accommodation costs. As a rule, they are placed in a private apartment rented for them by the government. These migrant children are receiving the same medical care as Swedish children. Migrants are assigned a caseworker; they can receive free legal aid and participate in special courses of the Swedish language. They receive a daily allowance and in some cases they are even allowed to work 49 (Sampson & Mitchell, 2013). In Italy, the law does not 42 Article 24 (1), Convention on the Rights of the Child (CRC). 43 Article 27 (1) Parliamentary Assembly (2014). The alternatives to immigration detention of children' Doc. 13597, 15 September, 6 (last checked 14 January 2020) http://assembly.coe.int/nw/xml/XRef/Xref-XML2HTML-en.asp?fileid=21130&lang=en. Most European countries' policies appear to leave open the possibility for detention, which is counter to emerging international human rights standards increasingly supporting a no-detention policy for children which is detrimental to their best interests. Consequently, there are reports from civil society organisations which suggest that in some countries, there is a gap between law and policy on one hand, and what happens in practice on the other 51 (Mossou, 2017). For example, in Hungary where detention of migrant children appears to be prohibited, it is reported that when unaccompanied children apply for asylum and are aged over 14, they are transferred to the closed transit facilities at the border with Serbia where they are deprived of liberty 52 (European Union Agency for Fundamental Rights Report, 2017). In Belgium, while the country has seemingly been able to limit the detention of accompanied children, there have been concerns from civil society organisations which have led to the creation of a campaign "We do not detain a child. Full stop" 53 brings together 50 organisations against the government's late 2016 announcement to build a closed centre especially for families with children 54 (Mossou, 2017). In France, the annual report on administrative detention in France published by six civil society organisations present in detention centres details the systematic use of deprivation of liberty as a primary instrument of migration control. The report underlines that 2016 reached a record in terms of the number of children detained in spite of condemnations by the European Court of Human Rights 55 (Migreurop, 2014). 182 children were detained in mainland France and in one of the country's overseas territories, Mayotte, the number goes up to a dramatic 4, 2485 children detained 56 (Mossou, 2017).
These actions by European member states allude to the fact that they are determined to continue to enforce detention policies with regards to children and their families, despite its prohibitions by international human rights law in that regard. In view of this, the paper focuses on a discussion of the role played by

The Role of the European Court of Human Rights and Detention of Migrant Children
The European Court of Human Rights (ECtHR) is considered as one of the most important institutions in Europe with regards to the settlement of international legal disputes. Therefore, the right to challenge the lawfulness of detention before a court is a well-established principle of customary international law 57 (UN Human Rights Council, 2008), which an irregular migrant can rely on. Consequently, whilst the ECtHR has considered cases relating to the arbitrary detention of irregular migrants, it appeared to explicitly permit the detainment of irregular migrants for the purpose of enforcing migration control by virtue of its Article 5 (1) (f) "to prevent [a person] effecting an unauthorised entry into the country" 58 (Chetail, 2014). Indeed, the ECtHR held in line with the UK House of Lords 59 that detention of undocumented immigrants is "a necessary adjunct" to the "undeniable sovereign right to control aliens" entry 60 (Saadi v UK, 2008).
Whilst these pronouncements of the ECtHR appear to be controversial and in blatant support of detention, its perspective on detention of irregular migrants appeared to change in successive years with landmark cases in the Beligum and  No. 13229/03, para. 64;Chetail, ibid, 50-51. 61 ECtHR Application No 41442/07 (last checked 23 February 2020) http://www.asylumlawdatabase.eu/en/content/ecthr-muskhadzhiyeva-and-others-v-belgium-applica tion-no-4144207. closed transit centre run by the Aliens Office near Brussels airport, where aliens (single adults or families) were held pending their removal from the country 62 (European Court of Human Rights Factsheet, 2018). Considering the relatively young age of the children, the duration of their detention and their state of health as attested to by medical certificates during their detention, the European Court of Human Rights (ECtHR) found that the conditions under which the children had been held in the closed transit centre had attained the minimum level of severity required to constitute a violation of Article 3 (prohibition of inhuman or degrading treatment) of the ECtHR. In particular, the court emphasised that the extreme vulnerability of a child was a paramount consideration which takes precedence over the status of mother and/or child as an illegal alien.
Although the four children had not been separated from their mother in the present case, this was not sufficient to exempt the authorities from their legal obligation to protect the children. As such, the duration of time within which the children were held in the closed centre (one month) and the conditions of the centre not being suitable to house children for that duration was considered and confirmed by several reports before the Court.
The ECtHR took a similar stance in Kanagaratnam v. Belgium 63 . In this case, detention of the mother and three children (who were relatively older than the   65 ECtHR, Application Nos 39472/07 and 37474/07 (last checked 23 February 2020) http://www.asylumlawdatabase.eu/en/content/ecthr-popov-v-france-application-nos-3947207-and-3 947407 commodate families and were placed there for two weeks. In a similar manner as what obtained in the above two cases, ECtHR held that there had been a violation of Article 3 (prohibition of inhuman or degrading treatment) of the Convention with regards to the detention conditions of the children, especially as the couple's children were aged three years and 5 months old. The Council of Europe Commissioner for Human Rights had reported that the nature of the centres proved unconducive for children, including living arrangements, and perceived stress, insecurity, and hostile atmosphere. In contradiction with international child protection principles according to which the authorities must do everything in their power to avoid detaining children for lengthy periods. The court agreed that a two weeks' detention period was not particularly excessive but could appear to be so when considering the ages of the children who were not used to living within such distressing conditions. However, the Court found that France was not in violation of Article 3 of the Convention with regards to detention conditions of the parents, as the parents had not been separated from the children within the two-period or at any time 66 (European Court of Human Rights, 2018).
These pronouncements by the ECtHR ought to serve as a deterrent to States to exercise their sovereign right to detention of irregular migrant children with due care and caution in view of existing international human rights instruments which cater to the rights of irregular migrant children. Nevertheless, there still remains a blatant refusal by states to adhere to these international standards, resulting in a gulf between these proclaimed standards and the application of States legislation 67 to irregular migrant children. What then is the way forward?

Towards a Global Harmonised Migration Governance Regime for Irregular Migrant Children: Recommendations
The global migration regime comprises a complex, and often fragmented, institutional and legal architecture for international cooperation and dialogue on migration issues 68 (Migration, Human Rights & Governance, 2015). The ongoing tension between rights and reality echoes the schizophrenic nature of an international legal system which is grounded on two contradictory driving forces 69 (Chetail, 2013). On the one hand, due respect of non-discrimination is primarily ensured by a decentralised scheme entrusted to nation states. On the other hand, "the universal respect for, and observance of human rights and fundamental freedoms for all without distinction" is acknowledged as one of the founding grants and to their legal exclusion from rights, places them in a "legal limbo".
The Currently, a transnational network of scholars, practitioners, expert and students have developed the International Migrants Bills of Rights (IMBR), a soft-law framework which innovatively posits a legal definition of international migrants and fames the rights and needs of vulnerable migrants-including children 73 (Kysel, 2016). Thus, this article recommends that concerted efforts between civil society organisations in Europe and Australia, drafters of the IMBR and the International Detention Coalition (IDC) towards developing, investing and implementing these workable alternatives to detention centres will greatly improve States' orientation towards the treatment of irregular migrant children. This collaboration will ensure that the human rights of children are continually upheld in migration law and policy. Whatever action is further developed and/or proposed by the international community within the next decade 71 De Lucas, J. Immigracion e integracion en la UE: dos retos para el s, XXI, Eurobask, 11-13 in Estrada-Tanck (n 9) 168. 72 United Nations General Assembly A/72/173 (2017). Report of the Special Rapporteur on the human rights of migrants. 19 July, Paras 60 & 61. 73 Kysel (n 17) 32.
regarding protecting the human rights of irregular migrant children, it is imperative that the most appropriate solution which is based on the children's best interests and well-being, must be placed ahead of a States' externalization policies on migration, to ensure an effective harmonised governance framework for irregular migrant children.

Conclusion
Border controls and the attendant detention mechanisms utilised by States are an ever-present reality for the international community and for irregular migrants. Although international law cannot completely curtail the sovereign right of States to control persons who seek to enter and remain within their territories, international human rights law requires that arrangements for detention in these States should be-at the very least-humane and without prolonged institutionalization of irregular migrants and their children. Until these considerations are carefully examined by destination and transit states and alternative measures as proffered above are implemented, the issues of human rights violation and attempts at judicial interpretation of same will remain rampant in States.
