Research focus while a CERC Scholar - Regional free movement of people law: A new field of study for international migration law

The legal regulation of migration represents a critical challenge for the international community and is of concern to states across the world. Surprisingly, in an era of increasing fortification of borders, and broadening categories of migrants outside of the law, policies and laws facilitating free movement of people within a geographic region are experiencing a spectacular rise. Currently there are least thirty-three regional organizations – involving 174 states – with regional free movement law. This project is interested in the proliferation of regional free movement law, which is already transforming global and national mobility regimes, including visas, asylum, smuggling, and trafficking, labor, irregular, family, environmental migration and indeed citizenship itself. The specific objectives of the project include:

• To offer the first definition of regional free movement of people law, thus opening a new subfield of international migration law.
• To analyze each of the components present in such definition as well as their interactions.
• To globally map regional, bilateral, unilateral and soft law measures and norms enhancing regional free movement.
• To assess the transformative implications of regional free movement law by looking at its scope and, in particular, its effects on entry, stay, rights and protection from expulsion, in particular in South America, the Caribbean, East Africa and the Post-Soviet space.
• To reflect on their proliferation, as well as on their implementing potential and challenges, including as a result of the COVID-19 pandemic, and the need to engage with empirical analyses and ‘conditional international law theory’.

Career Achievements

Diego Acosta is a leading international expert on international, European and comparative migration law. His research is interdisciplinary, and links both practical and theoretical inquiry to offer a novel defense of a rights-based approach to migration regulation. His work discusses migration law as a central aspect of globalization, and analyses various processes of inclusion and exclusion and their profound implications for the rule of law in Europe, South America and elsewhere. He is the author of more than 50 publications and his latest monograph is entitled: The National versus the Foreigner in South America. 200 Years of Migration and Citizenship Law (Cambridge University Press, 2018). He has also participated as co-investigator in the project Prospects for International Migration Governance (MIGPROSP) which the ERC funded for the 2014-2019 with 2.1 million euros. He has also been one of the authors of the proposal for a Model International Mobility Convention led by Columbia University in New York. He has been requested to offer his legal opinion by Governments, Parliaments, International Organizations and law firms in Europe, the USA, South America, the Caribbean and Africa.
