1. Introduction
Migratory flows by sea are not a new phenomenon and, since the Indochinese crisisFootnote 1 in the 1970s, they are well known under the expression ‘boat people’. In the past, sea-borne migratory flows consisted of isolated episodes, of emergency waves related to specific historical events.Footnote 2 For the last twenty years arrivals by sea have become a regular phenomenon, in particular along the coasts of the Mediterranean Sea and of Australia.Footnote 3 This phenomenon has varied according to the seasons, and has been influenced by specific events, which have increased the number of arrivals for a period of time.Footnote 4 The sea has then become a regular route for migration and it is undoubtedly one of the most dangerous ones. In the year 2011 alone, it is estimated that 1,500 people have died trying to cross the Mediterranean;Footnote 5 according to Fortress Europe, over 18,535 people have died attempting these crossings since 1988.Footnote 6
In dealing with this human tragedy, destination states have adopted comparable policies aimed at preventing the arrival of irregular migrants by performing border control outside their territory. States of destination have commonly used measures such as (joint) patrolling, interception of irregular migrantsFootnote 7 on the high seas and in the territorial waters of third states,Footnote 8 and redirection of intercepted migrants to the coasts of third states. These practices are part of ‘de-territorialized border control’.
By ‘de-territorialization’, we mean ‘the detachment of regulatory authority from a specific territory’.Footnote 9 It might seem paradoxical to talk about ‘de-territorialized borders’, considering that borders traditionally define states’ territories.Footnote 10 However, the current practice of extra-territorial border control, i.e. controls performed (directly or indirectly) by a state outside its own territory,Footnote 11 shows a progressive shift from a territory-based regime to a function-based regime with no ‘a priori territorial limitation’.Footnote 12 Border control does not only consist of checking measures performed at the points of territorial access, but it includes a range of activities, which are not performed at the borders but which are functional to their control. Border control has been detached from the territorial border.
This detachment has consequences on the applicable legal framework, in particular in relation to the safeguards to which the individuals submitted to the control activities are entitled. For instance, the aforementioned activities aimed at contrasting irregular migration by sea have been highly criticized by scholars,Footnote 13 practitioners,Footnote 14 and civil society,Footnote 15 because they challenge the fundamental rights of the intercepted irregular migrants, in particular the principle of non-refoulement. The principle of non-refoulement protects individuals against being sent to a country where they fear torture and other inhuman and degrading treatments, persecution on the basis of the grounds listed in the 1951 Geneva Convention on the Status of Refugees (hereinafter the 1951 Refugee Convention),Footnote 16 or serious human rights violations. The principle of non-refoulement is an important limit to states’ discretion concerning their right to refuse entry into or to expel persons from their territory.
This principle of non-refoulement is then an important element of the legal regime applicable to states’ border management and is a fundamental yardstick for the de-territorialization of border control. In order to assess the fundamental role that the principle of non-refoulement plays in shaping the management of irregular migration and border control at sea, its content will first be discussed (section 2). The territorial scope of the principle is still debated both in literature and in practice.Footnote 17 This article supports its application wherever competent state authorities perform measures which pertain to border control (section 3).
The analysis in this article is based on the idea that a new approach to police activities at sea is much needed in relation to irregular migration. In fact, to migrate is not an illicit activity. The smugglers of the migrants are the ones carrying out an illicit activity at sea.Footnote 18 Migrants perpetrate an illicit act once they irregularly trespass or attempt to trespass an international border. Consequently, the measures that coastal states take at sea in order to prevent and control migrants’ arrival qualify as border control actions and the relevant legal framework then applies.
The legal framework of border control at sea however, differs from the framework applying to land borders because of the specificities of maritime frontiers. This article first defines maritime borders, highlighting their functional nature (section 3.1.), in order to then support the application of the principle of non-refoulement at sea, in its meaning of ‘principle of non-rejection at the maritime frontier’ (section 3.2.). Particular attention will be given to the decision of the European Court of Human Rights (hereinafter, ECtHR) in the case of Hirsi Jamaa and others v. Italy (hereinafter Hirsi case).Footnote 19 Some concluding remarks will be drawn on the legal and practical consequences of applying the principle of non-refoulement in shaping the de-territorialization of border control at sea (section 4).
2. The content of the principle of non-refoulement
The principle of non-refoulement is firstly expressed in Article 33(1) of the 1951 Refugee which states that:
No Contracting State shall expel or return (‘refouler’) a refugee in any manner whatsoever to the frontiers of territories where his life or freedom would be threatened on account of his race, religion, nationality, membership of a particular social group or political opinion.
At the drafting Committee of the 1951 Refugee Convention, the non-refoulement clause was described as ‘an exceptional limitation of the sovereign right of States to turn back aliens to the frontiers of their country of origin’.Footnote 20 It is now considered the core of asylum-seekers’ protection.Footnote 21 It guarantees that refugees are not submitted again to the persecution which has caused their departure. Moreover, it responds to the refugees’ need to enter the asylum country, even if it does not explicitly guarantee access to the territory of the destination state or admission to the procedures granting refugee status. Actually, some authors have tried to support the existence of an additional obligation aimed at binding states to admit individuals applying for protection into their own territoryFootnote 22 but, for the time being, states practice cannot confirm these attempts.Footnote 23
Noll gave a definition of the principle which highlights its practical implications: ‘Non-refoulement . . . could be described as a right to transgress an administrative border’.Footnote 24 Starting from this understanding, it is important to address the question concerning the application ratione personae of such a ‘right to transgress’.
Article 33 of the 1951 Refugee Convention applies to the so-called ‘statutory refugees’, i.e. the individuals embraced by the definition provided in Article 1 of the same convention, as modified by the 1967 Protocol relating to the Status of Refugees (the 1967 Protocol):Footnote 25
[the term refugee shall apply to any person who] owing to well-founded fear of being persecuted for reason of race, religion, nationality, membership of a particular social group or opinion, is outside the country of his nationality and is unable or, owing to such fear, is unwilling to avail himself of the protection of that country; or who, not having a nationality and being outside the country of his former habitual residence as a result of such events, is unable or, owing to such fear, is unwilling to return to it.
The cornerstone of this definition is the concept of ‘well-founded fear of persecution’. The meaning of ‘persecution’ has been lengthily debated by scholars aiming to enlarge the scope of Article 1.Footnote 26 State practice is not homogenous in that respect, even if it has consistently revealed a dominant trend of offering some form of protection to a “person whose life or freedom would be at risk as a result of an armed conflict or generalized violence if they were returned involuntarily to their countries of origin”.Footnote 27
The so-called ‘de facto refugees’Footnote 28 are not deprived of protection and enjoy the application of the principle of non-refoulement as provided by the complementary protectionFootnote 29 of human rights law.
The definition of refugee also includes a spatial requirement, i.e. the refugee must be ‘outside the country of his nationality . . ., not having a nationality . . . outside the country of his former habitual residence’. Consequently, Article 33 of the 1951 Refugee Convention only applies to individuals who have crossed an international border and it cannot come into play as long as a person is within the territorial jurisdiction of her/his state of nationality or residence.Footnote 30 We can then deduce that Article 33 does not apply in the territorial watersFootnote 31 and contiguous zoneFootnote 32 of the state of nationality or of habitual residence, but does apply in the territorial waters and the contiguous zone of the state of transit.
Moreover, concerning the ratione loci application of Article 33, the provision does not indicate any territorial limitation.Footnote 33 Some authors consequently argue that Article 33 applies wherever a state exercises its jurisdiction, even extraterritorially.Footnote 34 This approach is also embedded in the purpose of Article 33 which prevents the return to a specific territory, and not from a specific territory. Despite some criticisms,Footnote 35 this interpretation of the principle of non-refoulement is confirmed by the practice of states and of some international judicial bodies in the interpretation of the principle as provided by human rights treaties.
Violations of human rights are often, even mostly, the root cause of migration flows, turning individuals into refugees, asylum-seekers, and displaced persons. Independently of the causes of their departure, the Universal Declaration of Human Rights (hereinafter UDHR)Footnote 36 states that ‘[e]veryone has the right to leave any country, including his own, and to return to his country’ (Article 13(2))Footnote 37 and ‘[e]veryone has the right to seek and enjoy in other countries asylum from persecution’ (Article 14(1)). Pursuant to these two rights, everyone is entitled to flee a harmful situation he/she is experiencing or risks experiencing, but once outside the borders of his/her own country, no formal right guarantees his/her entry into another.
The preamble of the 1951 Geneva Convention recalled the UDHR; the 1967 Declaration on Territorial Asylum (hereinafter 1967 DTA)Footnote 38 reaffirms the content of its Article 14, clarifying that the individual does not possess a subjective right of asylum, but that he/she is merely entitled to request the status of refugee and the required state has a discretionary power to accept or refuse the request.Footnote 39 Notwithstanding the discretion states enjoy, to prevent an individual from asking for protection can imply a breach of Article 14 UDHR in its meaning of ‘right to request’, which is safeguarded by the principle of non-refoulement.
The non-refoulement principle in human rights law is backed by Article 3 of the Convention against Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment (hereinafter CAT),Footnote 40 which prohibits the removal of individuals to states where they risk being submitted to torture or other inhuman or degrading treatment, as recalled by Article 7 of the 1966 International Covenant on Civil and Political Rights (hereinafter 1966 ICCPR).Footnote 41 The Committee against Torture clearly affirmed the extra-territorial application of the principle of non-refoulement, as provided by the CAT, in the JHA v. Spain (Marine I) case.Footnote 42
At a regional level, protection against refoulement is also guaranteed by Article 3 of the 1950 European Convention on the Protection of Human Rights and Fundamental Freedoms (hereinafter ECHR),Footnote 43 Article 22(8) of the 1969 American Convention on Human Rights (hereinafter ACHR),Footnote 44 and Article 5 of the 1981 African Convention on the Protection of Human and Peoples’ Rights (hereinafter Banjul Charter).Footnote 45 Moreover, in the field of international humanitarian law, Article 45 of the 1949 Fourth Geneva Convention relative to the Protection of Civilian Persons in Time of WarFootnote 46 sets out that ‘[i]n no circumstances shall a protected person be transferred to a country where he or she may have reason to fear persecution for his or her political opinions or religious beliefs’.
The 1966 ICCPR also provides the obligation not to extradite, deport, expel, or return an individual to a country where there are well-founded suspicions concerning a risk of irreparable harm to the right to life guaranteed by Article 6. The right to life is also guaranteed by Article 2 of the ECHR, Article 4 of the ACHR, and Article 4 of the Banjul Charter.
In light of the several international instruments and of states’ practice, the non-refoulement rule is unanimously considered today as a customary norm both of human rights and humanitarian law.Footnote 47 However, a complete agreement has not been reached yet concerning its precise content, in particular in relation to its territorial scope. Its application at sea remains particularly debated because of the functional nature of the powers states can exercise at sea and the often contested exercise of jurisdiction by the intervening states. This particular aspect has been discussed and decided for the first time by an international judicial body,Footnote 48 i.e. the ECtHR, in the aforementioned Hirsi case.Footnote 49
The applicants (eleven Somali nationals and thirteen Eritrean nationals) were part of a group of about two hundred individuals who left Libya aboard three vessels with the aim of reaching the Italian coast. On 6 May 2009, when the vessels were 35 nautical miles south of the Italian island of Lampedusa, they were intercepted by three ships from the Italian authorities. The occupants of the intercepted vessels were transferred onto Italian military ships and returned to Tripoli on the basis of the 2008 Treaty of Friendship between Italy and Libya.Footnote 50 The applicants alleged a violation of Article 3 of the ECHR (prohibition of torture), Article 4 of Protocol No. 4 (prohibition of collective expulsion) and Article 13 (right to an effective remedy).
Concerning specifically the principle of non-refoulement, the Hirsi case has the merit to clarify both its territorial scope and content. Leaving aside for a moment the territorial scope, the ECtHR reaffirmed that the behaviour of the victim does not matter in order to enjoy the application of the principle, and thus confirmed the approach previously adopted in the Saadi v. Italy case.Footnote 51 The Court also affirmed that the principle of non-refoulement entails some positive obligations, such as the identification of the persons, even outside the territory, and the need ‘to find out about the treatment to which the applicants would be exposed after their return’;Footnote 52 moreover, ‘the Italian authorities should have ascertained how the Libyan authorities fulfilled their international obligations in relation to the protection of refugees’.Footnote 53 In the view of the Court, these positive obligations apply even if the intercepted migrants failed to ask for asylum.Footnote 54 It is worth noticing how the Court focused its reasoning and the application of Article 3 of the ECHR on asylum seekers and refugees. It clearly avoids making a general statement on the application of such obligations to all intercepted migrants. This might undermine the ‘absolute character of the rights secured by Article 3’.Footnote 55
3. The principle of non-refoulement at sea, or the principle of non-rejection at the maritime frontier
The question of the application of the principle of non-refoulement at sea arises when coastal states’ authorities perform migration control at sea. They prevent the irregular crossing of the territorial border by de-territorializing border control. The de-territorialized border becomes a maritime frontier (a). The functional nature of the maritime frontier justifies the application of the principle of non-refoulement at sea, in its meaning of non-rejection at the frontier (b).
3.1. The maritime frontier: A definition
3.1.1. The frontier in international law
The concept of frontier has multiple dimensions (historical, political, and economical) and its content varies on the basis of these dimensions, taken into consideration at a certain moment in time. The frontier is comprised of the junction of three sociological phenomena: the territory, the nation, and the state.Footnote 56 The frontier is an essential stabilizing element of a state.Footnote 57
Historically, the concept of frontier dates back to the Ancient Roman notion of limes. The limes was not a fixed and tangible frontier, but it was a ‘strategic’ border, that is the last front of the Imperial legions. Therefore the limes moved forward or retreated depending on the successes or failures on the battlefield. With the end of the Carolingian Empire the frontier became a legal object because of increasing delimitation problems. The frontier became the border. In the thirteenth century, borders gained importance in managing joint problems with neighbouring states – ‘fences make good neighbours’. The need of an international management of borders emerged.Footnote 58 The border, or frontier, became a means of peace and orderFootnote 59 between powers. Because of this role, the frontier could not be a ‘fluid’ limes anymore, but needed stability. This necessity is expressed by Article 62(2) of the Vienna Convention of the Law of Treaties (hereinafter 1969 VCLT)Footnote 60 which sets out that: ‘[a] fundamental change of circumstances may not be invoked as a ground for terminating or withdrawing from a treaty: (a) if the treaty establishes a boundary’.
Other than being stable, frontiers in international law are also objective. Delimitation treaties are binding erga omnes. Their stability has in some cases jeopardized the respect of fundamental principles.Footnote 61 Moreover, the 1978 Vienna Convention on Succession of States in Respect of TreatiesFootnote 62 provides that ‘[a] succession of States does not as such affect: (a) a boundary established by a treaty; or (b) obligations and rights established by a treaty and relating to the regime of a boundary’ (Article 11). This provision, which codifies a customary rule,Footnote 63 transposes in the field of states’ succession the respect for territorial integrity of sovereign states embedded in Article 2(4) of the UN Charter.Footnote 64 The stability of the frontier is a matter of general international law.Footnote 65
The frontier limits the exercise of territorial sovereignty; it exists in the space in which state's policies concerning the management of the territory take place. The frontier and its management consequently express in legal terms the values on which the territorial state or community (e.g., the European Union) builds its own identity.
Migration control is an important part of the management of borders. Frontiers are the dividing line between the territorial community and the ‘others’. Migration control requests a tight and concrete supervision of the territory, which is challenged at sea for two reasons: a practical one, due to the impervious marine environment; a legal one, due to the limited sovereignty states enjoy at sea. Moreover, there are no fixed checkpoints at maritime borders, but the border is the place where the control is carried out by the competent authorities. This fluidity of the maritime frontier derives from the functional nature of states’ jurisdiction at sea.
3.1.2. The functional frontier at sea
Coastal states’ sovereignty on land is the basis for their sovereignty in adjacent maritime zones. This relation between the territory and the sea has been consistently affirmed in international case law since the Grisbadarna arbitral award of 1909.Footnote 66 In the Fisheries case, the International Court of Justice (hereinafter ICJ) stated ‘[i]t is the land which confers upon the coastal State a right to the waters off its coasts’Footnote 67 and it affirmed the principle according to which ‘the land dominates the sea’ in the North Sea Continental Shelf cases.Footnote 68
The relationship between land and sea is not only ‘physical’, but has a primarily political, economic, and social nature.Footnote 69 The coastal state extends its interests and their protection on the adjacent maritime zones. This extension of the coastal state jurisdiction and the consequent obligations for the other maritime states was recognized by the Second Commission of the 1930 Hague Conference for the codification of international lawFootnote 70 and then codified in the United Nations Convention on the Law of the Sea (hereinafter LOSC).Footnote 71
The ‘irradiation’ of sovereignty on the sea generates two different kinds of maritime borders. First, there is the border drawn on a map, the delimitation. This border aims at delimiting the physical area in which the coastal state is entitled to exercise its sovereignty pursuant to the legal regime of the different maritime zones. The further the zone is away from the shore, the more limited are the powers the coastal state can exercise. These powers are tools for conserving and protecting those interests international law recognizes as fundamental in the considered maritime zone. They are functional to the protection of those interests, which may include migratory matters.Footnote 72
Second, there is a functional maritime frontier; this one ‘moves’ following the nature of the considered behaviour, the subject carrying out the behaviour and the maritime zone in which the behaviour took place. Concerning migration control, the border materializes where the competent authorities perform their activities of border control. When Italian authorities intercept a vessel transporting irregular migrants on the high seas and decide to redirect it,Footnote 73 they are exercising powers (whose legality may be challengedFootnote 74) which pertain to border control prerogatives. As recalled above, to migrate is not per se an illicit activity. Any measure aiming at preventing the illegal entry of migrants has its legal basis in border control policies and international border co-operation, such as the aforementioned Treaty of Friendship between Italy and LibyaFootnote 75 or the EU integrated border management (IBM).Footnote 76 Such legal basis, i.e. such legislative jurisdiction,Footnote 77 limits and determines the content of the enforcement jurisdiction of the intervening state, i.e. its power ‘to take executive action in pursuance of or consequent on the making of decisions or rules’.Footnote 78
When states prevent irregular entries by performing activities outside their territory, they bring with them the border and part of its legal regime. The partiality of the border's legal regime is due to its de-territorialization. The elements of this legal regime, which are closely linked with the territory, cannot apply. Conversely, the elements which are linked to the persons submitted to the control do apply.
The principle of non-refoulement applies in relation to the person submitted to the measure of interception and/or redirection and in consideration of the territory where this person is returned or sent. It binds the actions of states even when they de-territorialize the control of their borders. It is a fundamental element of the legal framework of this police activity.
In light of this reasoning, the ECtHR in the Hirsi case did not need to invoke ‘territorial’ arguments in order to assess the Italian jurisdiction and consequently the application of the principle of non-refoulement to the applicants. Surprisingly, the Court recalled the Italian code of navigation, which provides that Italian military vessels ought to be considered as being a part of Italian territory.Footnote 79 So, as the applicants were taken aboard Italian vessels, they were under Italian jurisdiction. This is quite an outdated position, which is not reflected in contemporary international law.Footnote 80 The behaviour of the Court triggers some doubts about how it would have decided the case had the applicants not been taken on board of the Italian vessels. The invocation of territorial arguments is unfortunate.
3.2. The content of the principle of non-rejection at the maritime frontier
The application of the principle of non-refoulement at the frontier, in its meaning of ‘non-rejection at the frontier’, is mostly accepted today.Footnote 81 It can be deduced from the combined application of the provisions guaranteeing the principle at stake and Article 31(1) of the 1951 Refugee Convention.Footnote 82 The latter provision affirms that the unlawful entry of asylum seekers does not exclude them from the scope of application of the protection. To avoid the irregular crossing of a border is almost impossible for a person fleeing from a situation of persecution or generalized danger. During the Indochinese crisis,Footnote 83 the Executive Committee (hereinafter ExCom) of the United Nations High Commissioner for Refugees (hereinafter UNHCR) affirmed:
It is therefore imperative to ensure that asylum seekers are fully protected in large-scale influx situations, to reaffirm the basic minimum standards for their treatment . . .. In situations of large-scale influx, asylum seekers should be admitted to the State in which they first seek refuge and if that State is unable to admit them on a durable basis, it should always admit them at least on a temporary basis . . .. In all cases the fundamental principle of non-refoulement – including non rejection at the frontier – must be scrupulously observed.Footnote 84
The non-rejection at the frontier was included in the principle of non-refoulement in instruments subsequent to the 1951 Refugee Convention, as the 1967 DTAFootnote 85 and the 1967 OAU Convention on Refugees,Footnote 86 which have appeared particularly important for the interpretation of the same Convention.Footnote 87 Since 1977,Footnote 88 the ExCom has brought forward this argument and restated it in relation to migration by sea in 1979:
It is the humanitarian obligation of all coastal States to allow vessels in distress to seek haven in their waters and to grant asylum, or at least temporary refuge, to persons on board wishing to seek asylum.Footnote 89
Moreover, scholars and international bodies have often pointed out that to deny the application of the principle of non-refoulement at the borders would be illogical. The asylum seekers who entered the territory of the destination state (even illegally) would actually enjoy a higher protection than those who present themselves (even legally) at the bordersFootnote 90, wherever such borders are.
The application of the principle of non-refoulement to police activities at sea implies that, at least, the intervening state shall not preclude asylum seekers from seeking asylum elsewhere and, thus, force them back to their country of origin or to an unsafe third country. The intervening state consequently has the minimum obligation to identify those among the migrants on board of the intercepted vessel who are entitled to ask for protection. This conclusion has been confirmed by the interpretation given by the ECtHR in the already mentioned Hirsi case.Footnote 91 However, to simply repel vessels to the high seas, without a forced diversion, does not necessarily imply a violation of the principle of non-refoulement.Footnote 92 The intervening state shall however make sure that repelling them does not put their life in danger. Such behaviour would be in contrast with the duty to render assistance at sea.Footnote 93
4. Concluding remarks on the de-territorialization of border control
The practical consequences of the application of the principle of non-refoulement at sea have been detailed in a leaflet edited by the UNHCR and the International Maritime Organization (IMO).Footnote 94 This document invites shipmasters – for cases in which people rescued at sea claim asylum – to
alert the closest RCC (Rescue Co-ordination Centre); [to] contact the UNHCR; [to] not ask for disembarkation in the country of origin or from which the individuals fled; [to] not share personal information regarding the asylum-seekers with the authorities of that country, or with others who might convey this information to those authorities.
It is regrettable that similar invitations are not repeated in the document concerning actions that governments have to take. However, such an obligation already exists on the basis of the 1951 Refugee Convention and the aforementioned human rights instruments, which apply at sea. The law of the sea and human rights law complement each other and support the application of international protection obligations at sea, first of all of the principle of non-refoulement.
The de-territorialization of border control does not unfold in a legal vacuum. On the contrary, the exercise of migration management and border control outside the territory comes with guarantees for the people submitted to the measures. Among these guarantees, the principle of non-refoulement plays a fundamental role in shaping not only the legal framework, but also the operative dimension of de-territorialized border control at sea.
