Key legal question
Whether the appellants were entitled to bring the public law appeal against the groundwater permits and concession
Extracted holding
The appellants had standing because the communes and the water association were sufficiently affected in their public tasks and interests.
Extracted reasoning
Under Art. 89 BGG, municipalities and similar public bodies may appeal when they are affected in a manner comparable to private parties or in their sovereign tasks, including protection of residents and immission-related impacts from works.
