Question juridique clé
Whether the recourse was admissible and the appellants had standing.
Solution extraite
The appeal was admissible only to the extent that B. could invoke his own protected interests; UNIA lacked standing on the merits, but procedural complaints were admissible.
Motifs extraits
Association standing was denied because only a small minority of members was affected and UNIA also invoked interests outside art. 88 OG. B. had standing as a nearby resident affected by traffic, noise and disturbance. Procedural complaints based on denial of justice remained reviewable.
