Introduction

In 2026, Spain’s migration policy features a striking paradox. The Government has launched one of the most ambitious regularization processes in Europe on land, defining migration as a matter of rights, an integration process and an economic reality. At sea, though, a steep decline in arrivals to the Canary Islands illustrates a different logic: prevention, containment and cooperation with third States before migrants reach Spanish or European territory. This shift raises one pressing question for the discipline of international law: when the regulation of maritime migration is taken farther away from the coast, do human rights obligations vanish or do they simply harden into something less apparent? The Spanish case is particularly current. Latest figures published by Spain’s Ministry of Interior show that maritime arrivals to the Canary Islands plummeted in the first half of 2026. Between 1 January and 15 June 2026, 3,267 people reached the islands by sea, against 11,284 in the same period during 2025. This is a reduction of over 70 per cent. Politically, such a reduction can be presented as a signal of effective migration management. Legally, though, it should prompt a more difficult question: What occurs before people vanish from the statistics of arrivals? Yet Spain has simultaneously shown an entirely different kind of receptiveness toward those already present on its territory. In Spain the extraordinary regularization process for migrants already living in Spain was approved by the Government in April 2026. By mid-June, hundreds of thousands of applications had reportedly been made, and international media subsequently reported that the final number of applications could exceed one million. The effort was framed not just as an administrative step, but as a right, social inclusion and demographic imperative. Spain has thus made relatively clear its message on land: living and working migrants should be legal rather than condemned to irreversible invisibility.

This post is concerned, above all, with State responsibility for human rights at sea. It examines the 2026 regularization not for its own sake, but for what it reveals when read alongside Spain’s maritime strategy: a State treating territorial presence as the threshold at which rights begin. Therein lies the paradox, and it is worth stating precisely. It does not consist in the mere coexistence of a generous policy on land and a restrictive one at sea; States combine openness and control routinely. It consists in their mutual dependence. The regularization rewards presence; the maritime strategy prevents it; and the first is made politically and practically possible by the second. Spain’s most rights-protective migration measure in two decades thus rests upon a practice that withholds comparable protection from the same category of persons at an earlier point on the same journey. A policy premised on the harm of legal invisibility on land is sustained by the production of legal invisibility at sea. The argument proceeds in three steps. It first situates the regularization and its logic of presence. It then turns to the maritime strategy that determines who attains presence, and shows that the two policies operate not as parallel tracks but as a single system. It concludes by drawing out the consequence for State responsibility: under the law of the sea and international human rights law, a State’s obligations toward migrants cannot be made contingent on the very presence it acts to prevent.

Presence Rewarded: The 2026 Regularization in Context

The scale and design of the regularization deserve closer attention, because they explain why the Spanish case is so compelling. Royal Decree 316/2026, approved by the Council of Ministers on 14 April 2026 and in force since 16 April, opened a single application window running until 30 June 2026. Applicants had to prove presence in Spain before 1 January 2026, at least five months of continuous residence and the absence of a criminal record; successful applicants receive a one-year residence and work permit. The Government estimated that around half a million people could benefit, and the process is the first extraordinary regularization Spain has undertaken in more than two decades, since the 2005 process aimed at irregular workers. In numbers alone, it is one of the largest legalization exercises in recent European history.

The political significance of the measure is also notable. It did not come only from the Government. It responds to a popular legislative initiative promoted by migrant associations, trade unions and civil-society organizations, backed by hundreds of thousands of signatures and admitted for consideration by the Spanish Congress with cross-party support. The Government has presented the decree as the first milestone of a broader plan for integration and intercultural coexistence, and has defended it on three grounds: human rights and social inclusion, demography, and the needs of the labour market. It also builds upon the 2024 reform of the Immigration Regulation, which eased the ordinary arraigo pathways to legal residence. Regularization in Spain is therefore not an isolated administrative gesture. It is part of a deliberate and publicly argued model of migration governance, built on legality and presence.

Seen from a European perspective, this choice runs against the prevailing current. The EU’s Pact on Migration and Asylum, adopted in 2024, prioritizes screening, accelerated border procedures and returns; several Member States have recently restricted, rather than expanded, avenues to legal status; and recent large-scale regularizations elsewhere in Europe have been either sector-specific or discontinued. Spain is thus doing something genuinely distinctive: legalizing presence on a mass scale at the very moment when the Union’s centre of gravity is shifting toward containment. Yet the same Spain converges fully with that restrictive current at sea. The sections that follow show that these two positions are not merely simultaneous; they are structurally linked.

Presence Prevented: Fewer Arrivals, Harder Legal Questions

If the regularization rewards presence, the maritime strategy examined in this section determines who attains it. It is not as though Spain is the only country to have to confront this dilemma. Throughout Europe and beyond, coastal states as a whole show more and more efforts to prevent maritime arrivals with respect to monitoring, interdiction, information-sharing, patrol cooperation and with agreements with third states. The aim is often to prevent departures rather than simply handle arrivals. Within a Spanish context, the Canary Islands route has seen cross-border cooperation with countries like Morocco, Mauritania and Senegal be the cornerstone of migration control. This architecture is not new. It was forged during the so-called cayuco crisis of 2006, when more than 31,000 people reached the Canary Islands in a single year, prompting the first Plan África, a network of bilateral cooperation and readmission agreements with West African States, the permanent deployment of Spanish officers in Mauritania and Senegal, and the first joint maritime operations coordinated by Frontex off the West African coast. Two decades later, the model has been progressively Europeanized: after record arrivals to the Canary Islands in 2024, the European Union and Mauritania signed a Joint Declaration establishing a migration partnership backed by €210 million, negotiated with the active involvement of Spain. The sharp decline recorded in 2026 is therefore not an isolated outcome. It is the intensified product of a twenty-year-old strategy of anticipatory, delegated border control. The practical consequence could be fewer vessels reaching the Spanish shores. But a smaller number of arrivals does not necessarily mean fewer people are left in danger or shielded from the abuse of violence or shunted into more remote routes. This poses one of the most difficult questions in modern migration governance: does a decline in arrivals signal more protection, or only greater control at a distance? This is where the law of the sea and human rights law have to be read in unison.

The interaction between this strategy and the 2026 regularization must be made explicit, because it is structural, not coincidental. First, externalization is what makes mass regularization politically possible: the Government can present the legalization of half a million people as responsible governance precisely because arrivals are falling and the maritime border appears to be under control. Second, the two policies operate sequentially on the same population: cooperation at sea filters who becomes present on Spanish territory, and regularization then legalizes those who passed the filter. Third, the regularization’s own eligibility rules embed this logic: because applicants must prove presence in Spain before 1 January 2026, a person intercepted, diverted or deterred at sea during 2026 is excluded from the process by the very policy that prevented their arrival. Regularization and externalization are thus not competing philosophies. They are two faces of the same system: a system of selective legality.

Presence as the Threshold of Rights: Externalization and State Responsibility

At this point the analysis must move from policy to law, because the system just described rests on an assumption that international law does not share: that a State’s obligations begin where its territory does. Maritime migration is frequently framed as a border-security issue, a smuggling-prevention problem or a matter of migration management. Those frames are not wrong. States certainly have a legitimate interest in restricting borders and combating criminal networks that prey on those without power. But the sea is not a legal vacuum. It is a regulated space where overlapping legal duties apply for states, ships and rescue authorities. UNCLOS Article 98 mandates States to provide aid for persons in distress at sea. The SAR Convention and SOLAS have duties in the area of search and rescue coordination and assistance. International human rights law, including the principle of non-refoulement, restricts the return or transfer of persons to places where they may face persecution, torture, inhuman treatment or other serious harm. In European legal terms, a further layer complicates the picture: the European Convention on Human Rights, which applies wherever State agents exercise authority or control over persons, vessels or maritime operations.

The central legal problem is not merely whether Spain rescues people once they are within Spanish waters. The harder question concerns practices that take place before that point: cooperation with third States, remote surveillance, operational support, shared intelligence and coordinated prevention of departures.

If a State contributes to a system designed to stop boats before they reach its jurisdiction, can it avoid responsibility by pointing to geography? If migrants are intercepted, diverted or prevented from leaving by third-country authorities with European support, where should legal responsibility begin and end?

International law has not fully resolved these questions, but it has made one principle clear: formal distance cannot automatically erase responsibility. The relevant issue is not only territory, but control, influence, knowledge and foreseeable consequences. Human rights obligations are most clearly triggered when a State exercises effective control over persons or operations. Yet modern externalization policies often operate precisely in the grey zone below direct custody: funding, training, equipment, intelligence, diplomatic pressure and operational coordination. This makes responsibility harder to prove, but not conceptually irrelevant.

Spain’s 2026 paradox illustrates this problem with unusual clarity. On land, the State recognizes that irregularity produces vulnerability, exclusion and legal invisibility. At sea, however, the policy goal often appears to be preventing irregular migrants from becoming visible in the first place. Regularization responds to the human reality of people already present. Externalization, by contrast, may prevent that reality from entering the legal and political field of view. This is why the paradox, as defined at the outset, is more uncomfortable than a simple contradiction. The two policies are, in fact, coherent: both treat territorial presence as the switch that activates rights. Regularization rewards presence; externalization prevents it. What looks like contradiction is better understood as a filter: the State keeps its generosity for those who are inside, and delegates exclusion to actors and spaces beyond its formal jurisdiction. The legal problem is that human rights law does not treat jurisdiction as a purely territorial fact to be managed strategically: where a State exercises control, influence or a decisive contribution over what happens to people at sea, obligations may follow it there.

The Human Cost of Non-Arrival

If presence is the threshold at which rights begin, then the decisive facts concern those who never attain it — facts that arrival statistics are structurally unable to record. On migration routes in 2025, at least 7,667 people died or went missing globally, according to the International Organization for Migration. UN/IOM data also recorded thousands of deaths and disappearances across the Mediterranean and the Atlantic route toward the Canary Islands. These numbers matter because they challenge a purely statistical reading of success.

Fewer arrivals may indeed reflect safer, more orderly migration. But it can also be a function of deterrence, containment, rerouting, underreporting or deaths that don’t make it legally visible.

Seen in this light, the Canary Islands route must be regarded not just as a Spanish or European problem, but as part of a broader case study in maritime governance. The same pattern holds in other countries: Italy and Libya, Greece and Türkiye, the United Kingdom and France, Australia and its offshore processing arrangements. Each is a national variant of the same filter: rights conditioned upon a presence that the State labours to prevent. In each case, States are trying to reconcile a set of three goals that are often competing and in opposition to one another — reducing irregular arrivals, avoiding deaths at sea and limiting legal responsibility. Externalization promises to deliver all three. In practice, however, pursuing the first can obscure the second and dilute the third.

This is an important lesson for international lawyers: maritime migration control cannot be evaluated only at the moment of arrival. Legal analysis should instead trace the process outwards: from disembarkation decisions, to coordination of rescue missions, to interception, to surveillance, to inter-State collaboration, to building capacity in third States. The further migration control is shifted away from European shores, the more important it is to ask who knew what, who enabled what, and who benefited from the arrivals that never took place.

Conclusion: Responsibility Beyond the Shoreline

Spain’s regularization process shows that irregular migration can be addressed through legality, inclusion and institutional recognition. That makes the maritime side of the policy more legally uncomfortable. If the State accepts that invisibility is harmful on land, it should not rely on invisibility at sea as a tool of governance. The 2026 experience shows, moreover, that the two policies are not parallel tracks but one system: regularization legalizes those whom externalization has allowed to arrive, and excludes those it has kept away. That is the paradox in its final form: a humanitarian achievement inseparable from the machinery of exclusion that makes it possible.

The point is not that Spain has no right to manage its maritime borders. Nor is it that every form of cooperation with third States is unlawful. Rather, the point is that border control cannot be used to transform human beings into legal absences. Search and rescue duties, non-refoulement and human rights obligations cannot depend solely on whether a boat manages to reach the beach.

A serious human rights approach to maritime migration should therefore measure success differently. Not only by how many boats arrive. Not only by how many departures are prevented. But by what happens to those who are intercepted, rescued, diverted, returned, stranded or deterred.

The real legal question is not whether Spain has reduced arrivals to the Canary Islands. The question is whether the reduction has been achieved in a way that preserves access to rescue, protection and accountability.

Spain’s 2026 migration paradox is thus more than a national policy debate. It is a warning about the future of human rights at sea. If rights are recognized once migrants are inside the territory, but weakened when they are still at sea, then the line between protection and exclusion becomes a matter of maritime geography. International law should resist that outcome. The sea is not a zone where human rights disappear. It is precisely where they are most urgently needed.
