Questione giuridica chiave
Whether the furnace had an essential non-conformity justifying avoidance of the CISG contract and restitution of the advance
Decisione estratta
The buyer failed to show a non-conformity of the required seriousness; only a minor, easily repairable defect remained, so avoidance was not justified.
Motivazione estratta
The cantonal court established that the alleged defects were absent, except for one minor defect. On the established facts, the contract requirements under the CISG were not violated in an essential way.
