Rubber boats: Transnational legal encounters in the Mediterranean - Prof Tanja Aalberts

In the mare liberum, seafarers are protected by the age-old maritime duty to rescue anyone in distress at sea. This principle has also been codified in various treaties, including the 1974 Safety of Life at Sea (SOLAS) Convention. This convention was adopted in response to the Titanic disaster and mainly focuses on safety on board of commercial ships. But the most vulnerable people at sea nowadays clearly are irregular migrants, sailing by rubber boats rather than cruise ships. Formally, these migrants are also protected by the non-refoulement principle under refugee and human rights law. Yet in practice, they are subject to a politics of protection which operates through an intermeshing of different legal regimes. Moreover, the rubber boats play a crucial role in this politics of protection, and ultimately preclude the irregular migrants from the protection of the non-refoulement principle. Through the case of the rubber boat, as a transnational legal encounter of people, rules and objects, I investigate the uneven geographies and temporalities of international law as an everyday practice. Moreover, by paying critical attention to how objects participate in actualising certain sets of relations and potentials over others, the concept of transnational legal encounters enables us to critically re-think the production of meanings, legalities and politics, layering complexities to law’s work in and to the world.
