Kaum im Amt, wies Innenminister Dobrindt (CSU) die Bundespolizei an, Asylsuchende an Grenzen zurückzuweisen – offenbar ein Verstoß gegen EU-Recht. Mit dem IFG haben wir interne Dokumente erhalten, die zeigen: Er ignorierte bewusst die Einschätzung seiner Fachleute. fragdenstaat.de/artikel/exkl...

Gerald Knaus fordert wie immer Drittstaatenabkommen nach #Ceuta. Das ist absurd, denn: Gerade mit Marokko will man ja ein Drittstaatsabkommen aushandeln. Wo sollen denn marokkanische Migrant*innen hin? Das führt doch zu nichts. www.tagesschau.de/ausland/euro...

60,000 migrants reached Ceuta within 24 hours – dozens died attempting the crossing. JONAS BORNEMANN examines whether EU law offers real tools to respond, and what the political blame game reveals about solidarity between Member States. verfassungsblog.de/ceuta-eu-mig...
Quote from the piece by Jonas Bornemann: “The events in Ceuta expose the volatility of a legal regime that accepts that large numbers of persons remain trapped at the external border without any real prospect of entry.”

My article examines detention in the current draft of the EU Return Regulation, which was supported by right-wing and far-right parties in the EU Parliament. The desperate attempt to increase return rates relies on deterrence rather than effectiveness and violates human rights.
