Question juridique clé
Whether the cantonal government had to recuse itself because it had earlier sent a message supporting the district heating project.
Solution extraite
No objective appearance of bias existed; the message was part of the normal exercise of governmental functions and did not predetermine the later appeal.
Motifs extraits
Under Art. 29(1) Cst., recusal requires objectively established circumstances creating an appearance of partiality. General governmental positions do not suffice absent a personal interest, expressed hostility, or a fixed prior opinion on the specific case.
