The Council of Europe Commissioner for Human Rights, Michael O’Flaherty, warns that externalised asylum and migration policies must be carefully designed to avoid serious human rights risks. His report highlights how transferring asylum, return, and border control functions to other countries can expose migrants to torture, arbitrary detention, and collective expulsions. Particular risks arise in the external processing of asylum claims, return procedures including “return hubs,” and outsourcing of border control. The Commissioner calls on states to adopt precautionary approaches, safeguard vulnerable people, and ensure transparency and accountability.
