Kernrechtsfrage
Whether the appeal was sufficiently reasoned to challenge the cantonal findings on defect causation, repair costs, and productivity loss.
Extrahierter Entscheid
The appellant did not engage with the cantonal court's precise reasoning and therefore failed to satisfy the federal motivation requirements.
Extrahierte Begründung
Under the LTF, factual criticism must be specific and show arbitrariness. The submissions were largely generic and did not confront the passages of the expert report relied on by the cantonal court.
