Kernrechtsfrage
Whether the appeal was admissible despite the festival date having passed
Extrahierter Entscheid
The case remained justiciable because the issue may recur under similar circumstances and would otherwise evade timely judicial review.
Extrahierte Begründung
The Court waived the current practical-interest requirement since the festival recurs annually and the legality of loudspeaker limits could not usually be reviewed in time.
