Kernrechtsfrage
Whether the appeal remained admissible despite the challenged measures having ended
Extrahierter Entscheid
The absence of a current practical interest was excused because the short-term measures were unlikely to be reviewed otherwise and could recur.
Extrahierte Begründung
Repeated restraints and isolation, together with the continuing basis for involuntary placement, made recurrence possible; a declaratory claim remained permissible.
