@coldjoint,
Berlin is a state: do states in the USA usually ask the citizens before the state government/governor makes a decision?
Kiel is a city. Do US-city authorities ask their inhabitants before making a decision?
Both Kiel and Berlin have representative governments. (If you don't know what that is: look it up)
Refugees/asylum seeker's affairs are regulated under federal law. So, for legal reasons this would only be possible if the Federal Ministry of the Interior declares its agreement.
Since you are so interested in the details, here some relevant laws:
- the Schleswig-Holstein's state municipal code in
>here> (in Germ, but easy to understand for you as a law enthusiast)
-
Constitution of Berlin (paragraphs related to how the state is governed, in German)
- since the SAR 'Lifetime' is registered in the Netherlands/Dutch flagged, has a German crew and is operated by the German aid group Mission Lifeline, there might be others laws relevant as well,
- you certainly know the European and German asylum laws. (Start with the German Constitution ...)
