Question juridique clé
Whether the 1992 administrative agreement for reimbursement of consolidation costs was valid without a specific statutory basis.
Solution extraite
The agreement was not arbitrary: the commune had a legal basis to intervene for safety, and analogies to equipment contributions or substituted execution were defensible.
Motifs extraits
The commune’s intervention rested on local communal powers and, if needed, the police clause. Even if a specific basis were required for the contract’s content, the cantonal court’s reliance on analogous rules was not untenable.
