Kernrechtsfrage
Whether the constitutional complaint had become moot after the appellant definitively left the school.
Extrahierter Entscheid
Yes. Once the appellant had finally left the school, the dispute lacked a current practical interest and had to be declared closed.
Extrahierte Begründung
Under Art. 72 BZP in conjunction with Art. 40 OG, a case without legal interest is to be struck from the docket; costs are decided summarily based on the situation before mootness arose.
