Key legal question
Whether the neighbors had standing to challenge internal building-related conditions of the permit
Extracted holding
Standing exists only for issues that can practically affect the neighbors' legal or factual position; purely internal compliance arguments and abstract public-interest objections do not suffice.
Extracted reasoning
The court held that only those norms may be invoked that have a real impact on the neighbors, especially regarding noise or odors. Alleged defects in insulation, ventilation, or accessibility measures would not improve the neighbors' situation in a concrete way and were therefore outside their protected interest.
