Kernrechtsfrage
Whether the detention review was conducted by an independent court and within the required speed.
Extrahierter Entscheid
The review satisfied constitutional and Convention requirements; the time taken was not excessive and no oral hearing was mandatory.
Extrahierte Begründung
The file was first decided quickly, then reviewed by the appellate court in a two-tier written procedure with exchange of submissions; this did not breach the duty to decide promptly.
