The symposium questions international migration law and policies in light of the evolution of contemporary democracies. As the title says, controls and hospitality are put on an equal footing to demonstrate the need to overcome a logic of opposition, of confrontation between these notions. As for the dialectic between sovereignty and human rights, it is necessary to explore possible ways of reconciling controls and hospitality. This Symposium is the result of the International Francqui Professor Chair awarded to Pr. François Crépeau.
