Key legal question
Whether the deportation detention was lawful, in particular because of risk of absconding and the prospects of removal.
Extracted holding
The detention was lawful; the appellant showed a concrete risk of absconding and the other statutory conditions for detention were met.
Extracted reasoning
He had been finally removed, did not leave Switzerland, failed to cooperate, committed offences, disappeared for a period, and repeatedly declared that he would not return. Removal still appeared feasible within a foreseeable time and the authorities acted with sufficient diligence.
