Questione giuridica chiave
Whether the damage calculation for the third construction stage of the town hall/community center was arbitrary
Decisione estratta
The cantonal court's calculation was not arbitrary in the result, because the CHF 800,000 connection fees were counted consistently in both the total costs and the contractor's contractual claims.
Motivazione estratta
The same amount was included on both sides of the comparison; despite confusing arithmetic, the final damage amount remained logically sound.
