Kernrechtsfrage
Was the municipal council competent to approve the supplementary credit, or did the municipal assembly have to decide?
Extrahierter Entscheid
The supplementary credit was a new, non-bound expenditure caused by substantial project changes and therefore had to be submitted to the municipal assembly.
Extrahierte Begründung
The original budget vote covered the project only in its then-known form. The later increase in usable area and related alterations amounted to a material project modification, so the extra costs were not merely bound follow-up costs.
