Kernrechtsfrage
Whether the federal appeal had become moot after the complainant's release and had to be struck off.
Extrahierter Entscheid
Yes. The involuntary placement had ended with the release, so the appeal had become moot and the proceedings were struck off.
Extrahierte Begründung
Because the challenged measure was no longer in force, the appeal under Art. 72 ff. BGG lacked a live object; the case was therefore discontinued under Art. 71 BGG in conjunction with Art. 72 BZP.
