Questão jurídica principal
Whether the municipality's administrative appeal was admissible despite its prior agreement and lack of specific standing grounds.
Decisão extraída
The municipality lacked a sufficiently substantiated legal interest and could not challenge the detail project.
Fundamentação extraída
It had already bound itself to the BUWAL guideline in the main proceedings and did not show why it was no longer bound or why the detail project impaired a protected interest.
