International Solidarity and the Global Compact on Refugees: What Role for the African Union and the European Union?

Abstract On the 70th anniversary of the UN Refugee Convention, this article examines the concept of solidarity and explains its relevance today, through the lens of the Global Compact on Refugees (GCR). While stressing the potential as well as the challenges for thorough implementation of the solidarity mechanisms established by the GCR, the article argues that regional organizations may contribute to meeting the GCR objectives. This is particularly urgent for regions that are most affected by migratory flows. In proposing new ways of approaching the concept of solidarity, the article suggests that the African Union strengthen mechanisms other than the physical sharing of refugees, including pooling resources to support states experiencing large influxes of refugees. In addition to a system of financial support for refugee protection, the article also recommends that the European Union ensures safe channels for arrivals and a more robust resettlement programme, to help realize the GCR objectives.

exact nature of the responsibility-sharing norm in international law is unclear, 8 the adoption in 2018 of the Global Compact on Refugees (GCR) 9 has to a large extent provided some clarity on how the concept of solidarity can be construed by equitably distributing the world's refugees among states through different responsibility-sharing tools. The GCR advises that pledges and contributions to be made at the Global Refugee Forum, could take different forms, including financial, material and technical assistance. 10 The quest for solidarity in international refugee law is not new 11 and has generated a thriving academic debate over the years. 12 Great expectations have also been generated by the GCR regarding a universal system of responsibility-sharing. 13 The harsh reality is that the paradigm of international solidarity has yet to materialize into solid obligations. The GCR is a promising political project, but its legal commitments remain "thin". 14 Departing from such an "illusory" 15 quest for universal solidarity, this article argues that the paradigm of responsibility-sharing in the CGR could result in significant binding obligations, if effectively integrated within regional refugee regimes. These could, in fact, provide the institutional structures as well as binding legal frameworks that the international refugee regime has lacked from the start. Two regions that are particularly affected by migratory flows (Africa and Europe) have also favoured legal forms of integration that are significantly advanced in the field of refugee protection. Despite differences in their political, socio-economic and cultural contexts, both regions show great potential to contribute to the debate on the understanding of solidarity as an essential feature for the future sustainability of the international regime for refugee protection. contd 2021).

(2017) 29 International Journal of Refugee Law 201 at 207. 9 The GCR was adopted by UN General Assembly In this connection, this article pursues a twofold goal. First, it aims to explain the particular meaning of solidarity given in the regional systems of refugee protection established by the African Union (AU) and the European Union (EU). Secondly, the research aims to illustrate how the paradigm of cooperation and responsibility-sharing set out in the GCR can be integrated within these regional systems.
To pursue this twofold aim, the article first reflects on the reconceptualization of solidarity, especially in its constitutive element of responsibilitysharing, from the start of the international refugee regime to the model established by the GCR. This shows the two-pronged nature of the principle of solidarity in international refugee law, consisting of both prescriptive and operational dimensions. Secondly, the focus shifts to the regional level, by critically discussing how the EU and the AU regimes connect with the notion of international solidarity. This will help address the opportunities and challenges for these regional systems to be at the forefront of effective refugee protection in the light of the GCR.
More specifically, the research examines the concept of African solidarity and how it has fared since the adoption of the 1969 Convention Governing the Specific Aspects of Refugee Problems in Africa by the Organisation of African Unity (OAU Convention). 16 It analyses African solidarity beyond the physical sharing of refugees between states. It sheds light on the need for African states to view the idea of solidarity with refugees from the perspective of providing or pooling financial resources to support states hosting refugees, as countries in the EU have, to a certain extent, already been doing and in line with one of the main objectives of the GCR, namely to ease pressures on host countries. After all, the African Charter on Human and Peoples' Rights provides in article 21(4) that "States parties … shall individually and collectively exercise the right to free disposal of their wealth and natural resources with a view to strengthening African unity and solidarity". 17 With regard to the EU, the article argues that solidarity has to be considered as a core principle of the European integration process that determines mutual obligations for member states. These obligations are contextualized by discussing, also through the lens of case law from the Court of Justice of the EU (CJEU), recent attempts to embed a responsibility-sharing mechanism within the Common European Asylum System (CEAS). 18 This helps explain the obligations stemming from article 80 of the Treaty on the Functioning of the EU (TFEU), which expressly mandates that the policies on border checks, 16  immigration and asylum "shall be governed by the principle of solidarity and fair sharing of responsibility, including its financial implications, between the Member States". 19 As a result, while criticizing the weak legal blueprint of the GCR, this article proposes a fundamental paradigm-shift, suggesting that, if coupled with brave political imagination, 20 regional actors can play a crucial normative role in enhancing solidarity and responsibility-sharing in refugee protection.

SOLIDARITY AS A DISTINCT FEATURE OF INTERNATIONAL REFUGEE LAW
The discourse on solidarity is not unique to international refugee law, as its first prominent usage arose in the context of contributions to the North Atlantic Treaty Organization (NATO). 21 Additionally, the notion of solidarity is implicitly embedded in the UN. Article 1(3) of the UN Charter 22 provides that achieving international cooperation on solving "international problems of an economic, social or humanitarian character" is among the UN's overarching purposes. Article 56 of the UN Charter obliges states to "take joint and separate action in cooperation" with the UN. 23 In the field of refugee protection, while the concept of solidarity has been persistently invoked, it remains "complex, multi-dimensional and normative". 24 Boswell notes that the notion of solidarity, mainly understood as "burden-sharing" or "responsibility-sharing" has a chequered history. Since the 1950s, the concept has developed as a "principle for promoting international cooperation among states receiving refugees", 25 especially in situations where there is a mass influx of asylum seekers. 26   burdens on certain countries", thereby acknowledging the need to foster international cooperation for sharing responsibility for hosting refugees. In an attempt to substantiate the concept of solidarity in refugee protection, Martins notes that "solidarity establishes that States have an obligation to share the responsibility of finding durable solutions for refugees who have been deprived of a community". 28 This clearly captures the essence of the international paradigm of solidarity: while at the prescriptive level the concept needs to be predicated in favour of the refugees (solidarity with the refugees) in order to find adequate solutions for their safety, at the operational level it requires states to be cooperative (solidarity among states) in assisting states hosting refugees with effective responsibility-sharing mechanisms.
This two-pronged approach to solidarity is common in regional systems. For instance, as explained in greater detail below, in the African context, solidarity could broadly mean "African humanism" as a "philosophy of compassion, community and solidarity". 29 In the EU, Advocate General Sharpston recently clarified that solidarity "requires one to shoulder collective responsibilities … burdens to further the common good". 30 However, while numerous international instruments stress the need for international solidarity to refugees and cooperation among states, 31 not much has been achieved. 32 In an attempt to shed some light on the evolution and understanding of the concept of solidarity in international refugee law, this section elaborates on the practice of international refugee law from the UN Refugee Convention until the recent GCR. 28 G Martin "International solidarity and co-operation in assistance to African refugees: Burden-sharing or burden-shifting" (1995)

Solidarity in the normative set-up of the UN Refugee Convention
The concept of solidarity in relation to refugees has been present since the start of the international refugee protection regime. Recital 4 of the UN Refugee Convention provides for international cooperation in order to handle refugee situations across the world. The issue of international support to relieve the "burden" on states receiving large numbers of refugees was initially considered for inclusion in the operative part of the convention. The proposal was to link it to the question of admission of refugees to consolidate the provision in article 14 of the Universal Declaration of Human Rights on the right to seek and enjoy asylum. 33 Over the years, and even before the adoption of the GCR, the UNHCR has stressed the role of solidarity in refugee protection also with a view to finding durable solutions for refugees. 34 As emphasized by Boswell, since the adoption of the UN Refugee Convention, solidarity, in its constitutive element of burden-or responsibility-sharing, has been interpreted as requiring two main sorts of actions. The first has been providing financial assistance for countries of asylum, usually less developed states, to help them with the care and maintenance of refugees, mainly through funding the activities of the UNHCR in these countries. The second type of actions has involved "physical" as opposed to financial burden-sharing, ie the distribution of refugees among states. 35 Through the mandate in its statute 36 and the provisions of the UN Refugee Convention, the UNHCR has encouraged and supported states in implementing the principle of responsibility-sharing by way of local integration, 37 voluntary repatriation and resettlement, 38 together referred to as "durable solutions". According to the UNHCR, a durable solution is one that ends the problems associated with displacement and allows people to resume their normal lives in a safe environment. 39 In order to foster a more reliable and effective international response and ensure greater equity in the sharing of responsibilities, in 2002 the UN High Commissioner for Refugees (UNHCR) launched a process of global consultations on international protection, which gave particular attention to improving protection tools. These consultations led to the development of the Agenda for Protection, which gave rise to the Framework for Durable Solutions for Refugees and Persons of Concern (Framework for Durable Solutions), among other initiatives. 40 According to the UNHCR, 41 the Framework for Durable Solutions proffers models for improved targeting of development assistance for refugees through initiatives known as: Development Assistance for Refugees; Repatriation, Reintegration, Rehabilitation and Reconstruction; and Development through Local Integration, based on broad-based partnerships between governments and humanitarian and development actors. Durable solution arrangements have used both as a protection tool, as well as a tool for responsibility-sharing by states with the support of UNHCR even before the formal Framework for Durable Solutions was developed in 2003.
In its Millennium Declaration the UN General Assembly (UNGA) provided a further boost to the need for international solidarity, by stating, inter alia, that global challenges must be managed in a way that distributes the costs and burdens fairly in accordance with basic principles of equity and social justice. In other words, "those who suffer or who benefit least deserve help from those who benefit most". 42 While this statement does not specifically mention refugees or asylum seekers, with over 70 million people forcibly displaced worldwide, 43 it is safe to say that responsibility-sharing and solidarity with regard to the global displacement problem is essential to international relations in the 21st century. There have been many impressive instruments and initiatives geared towards responsibility-sharing both at international and regional levels. However, due to the ever-increasing number of displaced persons worldwide, a reduction in financing for refugee operations and an increasing number of states refusing to accept refugees, the need to find a more specific and coordinated platform for international solidarity has become ever more pressing.

Restructuring solidarity in the 2018 Global Compact on Refugees
A more decisive emphasis on solidarity in refugee protection was initiated in 2016 by the UNGA hosting a high-level Summit for Refugees and Migrants that aimed to improve the way in which the international community responds to large movements of refugees and migrants. As a result, all 193 UN member states unanimously adopted the New York Declaration for Refugees and Migrants (New York Declaration), 45 committing themselves to a more equitable sharing of responsibility for hosting and supporting the world's refugees, while taking account of existing contributions and states' different capacities and resources. The New York Declaration has been described as a milestone for global solidarity and refugee protection at a time of unprecedented displacement. 46 The commitments that member states agreed reflect that the "protection of those who are forced to flee, and support for the countries that shelter them, are a shared international responsibility -a responsibility that must be borne more equitably and predictably". 47 The New York Declaration called on UNHCR to initiate and lead the development of a Comprehensive Refugee Response Framework (CRRF) in close coordination with relevant states, including host countries, and involving other relevant UN entities, for each situation involving large refugee movements. 48 Through the declaration, states also agreed to continue to improve international responses by working towards a global compact on refugees. This was achieved with the adoption of the GCR on 17 December 2018. Although non-binding, the GCR reflects the political will of state parties to enhance cooperation and solidarity with both refugees and their host communities. Betts notes that, "since the creation of the modern refugee system, there has been a disjuncture between a strongly institutionalized norm of 'asylum' and a weakly institutionalized norm of 'responsibility sharing'". 49 The GCR addresses this gap in international refugee protection. contd in the refugee context. Although state support is discretionary, even under the current GCR, it has however introduced an avenue for states to make commitments through the Global Refugee Forum where states come together to make pledges. The GCR acknowledges that countries that receive and host refugees, often for extended periods, make an immense contribution from their own limited resources to the collective good, and indeed to the cause of humanity. Accordingly, the GCR stresses the need for such countries to receive tangible support from the international community as a whole in leading the response. 50 This takes into account that there is no clear obligation for non-refugee-hosting countries. 51 The GCR's objectives are manyfold and embody the sense of solidarity that must permeate international refugee law. The GCR aims to ease the pressures on host countries, particularly low and middle-income countries, through contributions from other states and relevant stakeholders; 52 it enhances refugee self-reliance, expands opportunities for refugees to access, as appropriate, education, healthcare and services, livelihood opportunities and labour markets, without discriminating among refugees and in a manner that also supports host communities; 53 it aims to expand access to third country solutions, by expanding resettlement places and complementary pathways for admission to third countries; 54 and, finally, it supports conditions in countries of origin for a safe and dignified return, by providing development assistance to countries of origin, in line with the 2030 Agenda for Sustainable Development and other relevant frameworks. 55 The GCR, therefore, "emanates from fundamental principles of humanity and international solidarity, and seeks to operationalize them through responsibility-sharing to better protect and assist refugees and support host countries and communities". 56 Moreover, the GCR adds a few new initiatives to the concept of international solidarity. These include the Global Refugee Forum, arrangements to support a specific refugee situation, and proposed key tools for effecting burden-and responsibility-sharing. 57 These initiatives provide the necessary mechanisms to galvanize international support and solutions for large-scale displacements across the world. 58 Despite its innovations, in the absence of legally binding arrangements, the effectiveness of the GCR's mechanisms is, nonetheless, questionable. 59 This opens the possibility that more effective solutions to strengthen the sense of solidarity in international refugee law can be achieved at the regional level 50 GCR, para A14. 51 Betts "The Global Compact on Refugees", above at note 49 at 623. 52 GCR, para 50. 53 Id, para 13b. 54 Id, para 18.

SOLIDARITY AS A PILLAR OF REFUGEE PROTECTION AT THE REGIONAL LEVEL?
This section assesses the concept of solidarity in the constitutive element of responsibility-sharing in the regional contexts of the AU and EU. The specific objective of this section is to appraise and compare the legal understanding of solidarity in refugee protection and the legal mechanisms in place for responsibility-sharing, and the actual application of the concept in the two regions. The aim is to make recommendations for the implementation of the major arrangements provided for by the GCR at regional level.
The distinct features of African solidarity in the regional legal framework It has been observed that the first regional instruments for the protection of refugees in Africa arose as result of the large scale displacements following the decolonization process that swept across the continent in the 1960s. 60 Mujuzi noted that, "as early as 1964, African countries realised that some countries, such as Uganda, Burundi and Tanzania, were facing problems related to hosting refugees and that the international community was not paying sufficient attention to the problems these countries and the refugees they were hosting faced". 61 Due to the heavy and unequal responsibility on a few states, there became an increasing call for solidarity to resolve the refugee problems and other challenges confronting the continent. On the one hand, this call for solidarity institutionalized the spirit of "African humanism" in the first ever regional legal framework on refugee protection, while, on the other hand, it triggered a process aimed at expanding the regional arrangements for refugee protection. These aspects are analysed below.

Solidarity as an institutionalized representation of African humanism
When the OAU was established in May 1963, African heads of state and government affirmed in the Charter of the OAU, inter alia, that the purpose of the OAU (now the AU), was to promote the unity and solidarity of African states, coordinate and intensify their cooperation and efforts to achieve a better life for the peoples of Africa. 62 Even before the enactment of the OAU Convention in 1969, solidarity in the African context has broadly symbolized "African humanism". 63 As emphasized by Winks, "the solidarity rights rather represented an African emphasis on fraternity, reciprocity and compassion. African humanism has been applied in practice as a viable and valuable legal philosophy". 64 While most African states became party to the UN Refugee Convention shortly after gaining their independence, many soon began to "express increased dissatisfaction that the international refugee instruments did not reflect the realities of the refugee situation in Africa". 65 This necessitated the inclusion of a provision on responsibility-sharing and solidarity in the OAU Convention, which is the legal basis of the concept in the African refugee context. Specifically, the OAU Convention provides: This provision creates a level of obligation on member states in the spirit of "African solidarity" to "endeavour to ease the burden of some of their members who have difficulty in coping with the refugees crossing their borders". 67 The principle of responsibility-sharing can also be inferred from the expansion of the definition of "refugee" in the OAU Convention to cover "external aggression, occupation, foreign domination or events seriously disturbing public order in either part or the whole of his country of origin or nationality". 68 Wood noted that: "[B]y extending refugee protection on the African continent beyond persons with a well-founded fear of persecution, to those fleeing more widespread and generalized forms of harm, such as political unrest, civil war, and even natural disaster, the expanded refugee definition has been praised for its liberal and humanitarian nature, for being 'more realistic about the nature of contemporary refugee scenarios' and for depoliticizing asylum by allowing states to recognize refugees 'without implicitly accusing another government of being persecutory'". 69 In addition to sharing the responsibility for hosting refugees, the application of the OAU Convention's definition removes the complexities associated with the definition in the UN Refugee Convention and makes it easy for African countries to share in solidarity and alleviate the burden faced by neighbouring countries, which may not be captured by the definition enshrined in the UN Refugee Convention. In the emerging discourse of the concept of "climate refugees", the aspect of "events seriously disturbing public order" in the OAU Convention could be ripe for exploration in the African context.
Nonetheless, this institutionalized representation of African humanism and solidarity has been challenged by the evolution of refugee policies in postindependence Africa. In fact, while initially, between the early 1960s and 1990, African countries generously welcomed refugees through an "open door policy", from the 1990s onwards the commitment to responsibilitysharing was replaced by protection fatigue. 70 Many refugee-hosting countries in Africa began to express domestic concerns, ranging from internal security to infrastructural and environmental concerns. These included: fear that refugees coming from civil war situations may bring weapons into their host countries; strains on socioeconomic resources; and the depletion of natural resources. These aspects, coupled with limited assistance and a lack of sustained cooperation from the international community, have been noted as some of the reasons why many African states closed their borders to refugees. 71 As a result, over the years, the treatment of refugees in the region began to fall below basic standards of international law. 72 A progressive expansion of regional arrangements for responsibility-sharing and solidarity: A potential to implement the GCR?
Despite the protection fatigue for refugees witnessed in the 1990s, in furtherance of article II of the OAU Charter, Africa continued to register a progressive expansion of regional arrangements for responsibility-sharing and solidarity.
While the "open door policy" for refugees was confronted with the huge economic realities of the period, it became clear for many African states that there was more need for international solidarity and cooperation to resolve the problems confronting the continent. The need for cooperation and responsibility-sharing reignited the principle of African solidarity and humanism.
In the 1990s, even to the beginning of the 2000s, when scholars would have suggested that international cooperation and solidarity would be difficult to attain in Africa, especially due to the worsening economic climate, the spirit of African humanism and solidarity was reawakened in Africa. From western Africa to eastern Africa, new cases of large-scale displacement sprang up, with AU members rising to the occasion. In West Africa, Liberia and Sierra Leone produced a considerable number of refugees as a result of a brutal civil war in 1989-2002. 73 The refugee situation in Liberia and Sierra Leone become a litmus test for the principle of international solidarity, responsibility-sharing and African humanism. 74 A practical example on responsibility-sharing was observed in the West African sub-region in June 2007 where, in furtherance of the obligation under article 2(4) of the OAU Convention, Liberia, Sierra Leone, Nigeria, the Economic Community of West African States (ECOWAS) 75 and UNHCR signed the Multipartite Agreement for the Local Integration of Liberian and Sierra Leonian Refugees in Nigeria. 76 Before the adoption of the GCR, in addition to the OAU Convention, the subregional ECOWAS-UNHCR Memorandum of Understanding (MoU) on Equality of Treatment for Refugees with Other Citizens of Member States of ECOWAS in the Exercise of Free Movement, Right of Residence and Establishment 77 was signed in 2007, which is very relevant in respect of the implementation of the GCR's regional and sub-regional approaches to responsibility-sharing. 78 In addition to reemphasizing the rights of refugees from West African countries to move freely, reside and establish themselves in the territories of member states like every other West African citizen, this MoU calls on UNHCR to establish a Regional Local Integration Management Unit (RLIMU). With the MoU in place and the RLIMU established, the GCR's regional and sub-regional 73 See TM Anjum, C Nordqvist and T Timpka "The hopes of West African refugees during resettlement in northern Sweden: A 6-year prospective qualitative study of pathways and agency thoughts" (2012) 24 Conflict and Health 1. 74 This conflict saw West African states such as Nigeria, Ghana and Côte d'Ivoire hosting thousands of Liberian and Sierra Leonian refugees for more than a decade: V Nmoma "The civil war and the refugee crisis in Liberia" (1997) Journal of Conflict Studies 1 at 18. 75 ECOWAS is one of the eight regional economic communities in Africa. 76 In the agreement, the Nigerian government committed, inter alia, to grant a set of rights to the refugees who were granted ECOWAS residence. These rights included full freedom of movement within Nigeria, the right to depart from and re-enter Nigeria (provided the holder's passport and ECOWAS residence permit remain valid), and the right to work in the formal and informal economies. See in particular para 6 of the agreement, available at: <https://www.unhcr.org/49e479ca22.pdf> (last accessed 13 December 2021). 77 Meeting of the Committee on Trade, Customs and Immigration, Accra, 25-27 September 2007. 78 See GCR, para 2.3. approach to responsibility-sharing, especially through local integration, is effectively settled in the West African region.
Another example of the progressive expansion of regional arrangements for responsibility-sharing and solidarity in Africa following the recommendations in the New York Declaration was observed in the East Africa region with the adoption of the Nairobi Declaration on Durable Solutions for Somali Refugees and Reintegration of Returnees in Somalia. This sub-regional approach, specifically for refugees, has been described as the first of its kind, as it allows countries in the sub-region facing a refugee situation to work together to protect and find solutions for them, with support and assistance from the international community. 79 A two-pronged understanding of solidarity in EU asylum law In Europe, solidarity has been invoked over the years following the "refugee crisis" of 2015. 80 In his Speech on the State of the Union in 2015, European Commission President Juncker stated clearly that, "where Europe has clearly under-delivered, is on common solidarity with regard to the refugees who have arrived on our territory". 81 However, from a legal point view, to date the obligations stemming from such a principle of solidarity are not clear. 82 The legal basis for solidarity is rather vague, as article 80 of the TFEU merely states that all policies in the field of border checks, asylum and migration and their implementation "shall be governed by the principle of solidarity and fair sharing of responsibility, including its financial implications, between the Member States". Scholars have pointed out that, instead of defining the scope of any legal obligations linked with article 80, EU institutions pursued a more operational approach "listing different measures that operationalize solidarity", 83 including the relocation of asylum seekers throughout the EU. Interestingly, in 2011 the European Parliament published a study on the implementation of solidarity, which, while stressing that the concept of solidarity has been left undefined in order not to limit its scope, includes a primary goal of fostering trust. 84 Solidarity, in the form of responsibilitysharing, is necessary to ensure Member states' loyalty as a minimal condition of trust, because, as cases like NS v UK and ME v Ireland 85 have clearly illustrated, blind trust in correctly implementing legislative instruments may not be sufficient.
Therefore, solidarity constitutes the paradigm under which adequate tools need to be elaborated "to assist other Member States to reach the standards set at EU level or even to compensate for their failure to do so". 86 It, therefore, entails, an axiological or prescriptive dimension as well as an operational one.

Solidarity as a founding principle of EU law
Solidarity has been referred to several times in CJEU case law as a founding principle of EU law in respect of asylum. 87 In Jafari, the CJEU mentioned "a spirit of solidarity", fair cooperation and common efforts between all member states towards the management of external borders, which inform each member state's responsibility and mutual accountability for actions concerning the entry and residence of third country nationals. 88 Moreover, in his lengthy opinion on the case concerning the relocation decisions brought by Slovakia and Hungary, Advocate General Bot affirmed that solidarity is among the EU's cardinal values, and a requirement that remains "at the heart of the process of integration pursued by the Treaty of Lisbon". 89 This argument was more recently echoed by Advocate General Sharpston in her opinion on the infringement procedure brought against Hungary, Poland and Czech Republic, referring back to the foundation of the "European project", tracing from the Schuman Declaration to the EU Treaty, to emphasize further that solidarity is a founding principle of EU law. 90 The advocate general concluded that solidarity is the lifeblood of the European project, by which member states and their nationals have obligations as well as benefits, duties as well as rights, lecturing the then applicant member states that the project does not end in the benefits they can claim, but requires them to shoulder collective responsibilities and burdens to further the common good. 91 The CJEU, in turn, adopted the advocate general's same line of reasoning without, however, further elaborating on the concept of solidarity. It referred to article 80 of the TFEU to reaffirm not only solidarity as a principle governing the EU's asylum policy, but also that the burden to cope with an emergency situation characterized by a sudden influx of third country nationals must therefore be divided between all member states. 92 In the same sense, the CJEU affirmed that solidarity is the objective of the relocation decisions that established the emergency mechanism to relocate asylum seekers from Greece and Italy, 93 thus justifying the sharing of the "burden" between all member states.
This axiological understanding of solidarity differs from the notion embedded in the AU system. The European project, in fact, mainly speaks to its member states without expressly upholding a sense of solidarity with refugees on the basis of humanitarianism. The EU notion of solidarity is more strategically political, and its prescriptive dimension can be better explained only when assessed in the light of the most recent operationalization of the principle. This can, in fact, contribute to identifying the legal obligations ensuing from such a principle.

Solidarity as a pragmatic obligation in the Common European Asylum System
The CJEU's understanding of solidarity upholds a practical component to the principle, that in turn informs the existence of duties and the obligation to share burdens and responsibilities, imposed on all member states. This connects to the operational dimension of international solidarity (solidarity among states) that is inferred from the interpretation of the UN Refugee Convention. According to Advocate General Bot, cooperation and solidarity among member states are duties that must underpin the CEAS. 94 Referencing articles 67(2) and 80 of the TFEU, the advocate general emphasized that solidarity is a pivotal element within the CEAS that must be "genuine and practical" and be shown towards the member states most affected by flows of asylum applicants that place disproportionate pressure on their systems. 95 91  The most recent developments in EU asylum law insist on the need to operationalize solidarity. This has been pursued by adopting temporary emergency measures, namely the decisions on the relocation of asylum seekers from Greece and Italy 96 and, lately, by designing permanent solidarity mechanisms to be embedded in the CEAS. While being criticized for being an unsuccessful experiment, the relocation decisions of 2015 97 deserve credit for pioneering the use of emergency legislation under article 78(3) of the TFEU in the face of the sudden influx of third country nationals into certain member states, namely Greece and Italy.
In that sense, Advocate General Bot emphasized that, given the de facto inequality between member states because of their geographic situation and their vulnerability in the face of massive migration flows, the adoption of the emergency measures provided for in article 78(3) of the TFEU confers a practical content and binding nature to the principle of solidarity, 98 and that the non-application of such decisions constitutes a breach of the obligation concerning solidarity and the fair sharing of responsibility expressed in article 80 of the TFEU. 99 In other words, the advocate general affirmed that, in taking article 80 of the TFEU into account when interpreting article 78(3), the conclusion must be that provisional measures such as relocation decisions should allocate the burdens of solidarity between member states, in a binding fashion, 100 stating that "it is the mandatory determination of the allocations per Member State which gives real scope to the principle of solidarity". 101 Accordingly, in her opinion on the infringement procedure against Hungary, Poland and Czech Republic, Advocate General Sharpston reaffirmed that ensuring that the relocation mechanisms work adequately and in sufficient numbers to relieve the intolerable pressure on frontline member states "is what solidarity is about". 102 Nonetheless, the operational character of solidarity in its horizontal interstate dimension does not exclude the need to construe such a principle vertically in the relationship between states and refugees. This clearly emerges from another case before the CJEU. In his opinion in Jawo, Advocate General Wathelet emphasized that the principle of solidarity and the fair sharing of responsibilities between member states must be a reality for the benefit not only of member states, but above all of the human beings concerned. This would translate into the need for member states, including national courts, to guarantee the full effectiveness of the rules, ensuring uniform minimum living conditions for the beneficiaries of international protection. 103 Regrettably, this last dimension has yet to materialize. The ongoing process to reform the CEAS reflects the efforts to design a permanent inter-state solidarity mechanism for the distribution of asylum applications throughout the EU but, as illustrated in the next section, very little attention is paid to the applicants' integration into the host society, which constitutes one of the durable solutions contemplated by the GCR.

The New Pact on Migration and Asylum and the Global Compact on Refugees
Solidarity is unsurprisingly one of the main pillars of the New Pact on Migration and Asylum (New Pact) proposed by the European Commission in September 2020, which stresses that member states must be able to "rely on the solidarity of our whole European Union". 104 Nevertheless, conceptually, the New Pact does not go much further than the well-known formula of solidarity already extracted from CJEU case law, as it states that responsibility must be divided between all other member states and that "all Member States should contribute". 105 Scholars 106 and civil society 107 have already attracted fierce criticism by claiming that this political platform is all but new and definitely unfit for the "fresh start" sought by the European Commission. The question is, therefore, whether the new set of legislative proposals can favour the ambitions envisaged by the GCR at least at the European regional level.
In an attempt to ensure a more pragmatic approach, 108 in the new Asylum and Migration Management Regulation 109 the New Pact proposes that member states can choose either to relocate asylum seekers, to sponsor returns to help another member state repatriate irregular migrants or to provide other types of support including external cooperation for migration management in countries of origin or transit. Such a model of mandatory but flexible solidarity can produce adverse effects, as it discourages member states from prioritizing the relocation of asylum seekers. Likewise, considering that, every year, only 40 per cent of third country nationals are effectively returned, 110 few expectations are raised by the new tool of return sponsorships. Finally, instead of acting as a catalyst for a consensus, this new framework seems rather to contribute to further fragmentation in the effective management of the CEAS, neglecting that "the enjoyment of equal rights and benefits stemming from membership in the EU carries equal responsibilities". 111 Scholars criticize the European Commission for having missed out on the opportunity to elaborate a true solidarity doctrine for the EU. 112 If the proposal were meant to create a mechanism to balance responsibility-sharing, an even system has remained elusive. The New Pact acknowledges that member states do not have the willingness to embrace true reform of the CEAS, especially so far as it concerns member states that wanted a tougher and stricter approach to asylum and migration. Reaching a compromise between the mandatory relocation requested by frontline member states and the no-relocation demanded by the Visegrad Four (Czech Republic, Hungary, Poland and Slovakia) with the introduction of the "mandatory flexible" solidarity system is proving extremely difficult. 113 This frustrates the potential of the EU to contribute effectively to the realization of the GCR objectives at the regional level. The EU has the potential to put in place the robust responsibility-sharing structures that the GCR proposes with the advantage of supporting these structures with binding obligations that can put the EU at the forefront of the management of refugee flows. However, what is needed is a paradigm shift: a change in the approach to solidarity in refugee protection that prioritizes humanitarian goals (such as resettlement schemes, safe access to the CEAS, free movement of the beneficiaries of international protection) over sterile national interests that focus on responsibility-shifts instead of solidarity.
