Key legal question
Whether the appeal against the removal order was admissible and whether the file-based procedure without oral hearing was sufficient.
Extracted holding
The appeal was admissible, but no oral hearing was required because the facts were sufficiently established in the record and no Convention right to a hearing applied.
Extracted reasoning
Art. 29(2) BV does not guarantee an oral hearing; under cantonal procedure the court may decide on the file and decline further evidence where its view is already formed.
