Key legal question
Whether Wangen an der Aare had standing to appeal the non-entry decision on its objection.
Extracted holding
The municipality was not sufficiently affected and could not invoke autonomy or any protected interest to challenge the non-entry decision.
Extracted reasoning
A Bernese municipality has no sovereign authority on Solothurn territory. The alleged impacts were too remote: the nearest settlement and the foot/bicycle path did not create the required local connection, and no concrete special municipal interest was shown.
