Kernrechtsfrage
Whether the cantonal court violated Art. 8 CC by misallocating the burden of proof regarding delivery and performance.
Extrahierter Entscheid
No. The cantonal court did not shift the burden of proof; it held that the supplier had proved performance and the buyer's objections remained generic.
Extrahierte Begründung
Art. 8 CC governs burden of proof, not the weighing of evidence. The cantonal court relied on the evidence in the file and on the inadequacy of the buyer's specific objections; that assessment cannot be reviewed in reform appeal.
