Question juridique clé
Whether privately acquired land costs at CHF 35/m2 could be included as chargeable construction costs in the contribution plan.
Solution extraite
Yes. The municipality could use the same unit price as a reasonable cost basis; only an obvious and manifest overpayment would require closer review in the contribution proceeding.
Motifs extraits
The court held that the contribution case is not the forum for fine-grained valuation disputes comparable to an expropriation compensation case. Some schematism in pricing must be accepted to avoid an unmanageable expansion of the proceedings. The appellant failed to show an obvious, objectionable overpayment.
