Kernrechtsfrage
Whether the administrative appeal was admissible against the cantonal interlocutory order refusing interim measures.
Extrahierter Entscheid
The appeal was formally available in principle, but the court could not proceed because the concrete controversy had become moot.
Extrahierte Begründung
The matter concerned only the interim order. Once the son had left Switzerland, there was no longer a current and practical interest in reviewing whether his continued stay should have been allowed temporarily.
