Kernrechtsfrage
Whether the appeal remained live despite the applicant's temporary release from the institution and the lapse of the 14-day deadline for the cantonal court to re-decide.
Extrahierter Entscheid
The case was not moot; the applicant still had a current interest because the detention had not been validly lifted by the competent authority and she could be returned to the institution.
Extrahierte Begründung
Only the authority that ordered the measure could release her, and no valid release had been shown. The late cantonal decision did not justify dismissal of the appeal as moot.
