Professor Slingenberg also researches how the domain of migration law relates to other areas of law, such as social law, administrative law and constitutional law, and which theoretical notions in law are relevant to the legal position of migrants who are territorially present (e.g. vulnerability, deservingness, non-domination, (social) membership).
Lieneke Slingenberg: "What I’ve dealt with in my research so far is not so much the right to admission or protection against deportation of migrants, but the treatment of migrants who are already in Europe or at its border. Consider their rights to housing, education, healthcare, work, aid and shelter. The withholding or supplying of such provisions is used by states as an instrument for migration control."
In her current research project (2019-2023), funded by NWO, she studies the (lack of) national, European and international regulation when it comes to spatial restrictions imposed on refugees and (rejected) asylum seekers, in the light of human rights law and the theoretical concept of freedom.
