Key legal question
Whether the Federal Office's authority complaint was admissible on the detention and proportionality questions.
Extracted holding
The complaint was inadmissible because it sought abstract review of case-specific issues that were no longer current after the respondent's removal from Switzerland.
Extracted reasoning
The detention and proportionality assessments depended on the specific facts of the case and did not raise a new legal question or prevent a concrete, imminent unlawful development. Since the removal proceedings had been successfully completed, the challenged issues lacked current relevance.
