Key legal question
Whether the public-law complaints were admissible, including whether the autonomy argument was new on appeal
Extracted holding
The complaints were admissible; the autonomy grievance was not considered a new ground in the circumstances.
Extracted reasoning
The communes had already raised autonomy in relation to standing before the cantonal court, and the cantonal court did not address it on the merits. The Federal Court also recalled the narrow exceptions allowing communes to invoke autonomy and related constitutional guarantees.
