Externalized Migration Governance and the Limits of Sovereignty: The Case of Partnership Agreements between EU and Libya

Can state sovereignty justify privileged receiving countries exercising authority over non-members in a third country to safeguard their own interests? Under the current migration governance of the EU, state sovereignty is manifested in migrant interdiction, interception and detention policies employed to prevent unauthorized migrants from reaching the EU, and even from attempting to embark on cross-Mediterranean journeys.
