Question juridique clé
Whether the cantonal court acted arbitrarily in treating certain paving works as common knowledge indicating outer development costs.
Solution extraite
Yes. The assumption that a parcel connection to main infrastructure never requires extensive paving works was not generally known and was untenable.
Motifs extraits
The extent of road opening needed for the pipe connection depends on the concrete site conditions; no fixed standard distance exists, so notoriety could not replace proof.
