Key legal question
Whether the municipal works constituted an adequate cause of the owners’ humidity and flood damage under neighbour-law liability.
Extracted holding
The appeal did not show any legal error in the cantonal finding that the municipal excavation and drainage works were one adequate cause of the damage, even if other factors also contributed.
Extracted reasoning
The court held that liability under Art. 679 and 685 CC does not require a single exclusive cause. The appellant merely challenged the evaluation of evidence and failed to explain why the works were not, according to ordinary experience, suitable to cause such damage.
