Key legal question
Whether the municipality's autonomy complaint against the cantonal annulment of the naturalization refusal was admissible and well-founded
Extracted holding
The municipality had standing to complain of interference with its autonomy, but the complaint succeeded only in part.
Extracted reasoning
Municipal autonomy exists in the naturalization field because the canton does not fully exhaust the matter and leaves a substantial discretion. The Federal Court may review whether cantonal authorities misapplied constitutional procedural guarantees.
