Key legal question
Whether the bank debit slip for the alleged CHF 20,173.65 heating repair payment could be admitted as a late piece of evidence under Art. 317 ZPO
Extracted holding
The debit slip was a late, inadmissible novelty because the appellant could and should have sought the evidence already in first instance with reasonable diligence.
Extracted reasoning
The court held that the appellant had no excuse: he could have contacted the bank earlier or searched all accounts from the outset. The short time frame around the invoice also made the search manageable.
