Abstract
South Tyrol, an Italian province with a German-speaking minority and an extensive political autonomy to protect its diversity, has witnessed the increasing arrival of migrants from foreign countries. The Province has extensive powers in matters concerning migration, especially the integration of the migrant population, and it is developing policies on the basis of the specific characteristics of its society. At the same time, its actions should submit to a general framework established by the Italian government as well as decisions taken at the European level. Combining political science and law approaches, the contribution explores the role played by regional, national and supranational actors in the shaping of South Tyrolean policies, including a legal analysis of national and international judgments on provincial laws and decentralized competences on migration and integration in South Tyrol. The analysis will reveal the problems and tensions among levels of governance vis-à-vis the management of immigration in territory characterized by complex diversity and robust but at same time feeble decentralized system of power.
