Questione giuridica chiave
Whether the Obergericht violated Art. 9 BV by assessing witness A.________'s testimony as insufficiently reliable to prove the disputed contract and debtor.
Decisione estratta
No. The court's appreciation of the evidence was not arbitrary; the witness did not clearly state who had awarded the order, and the reasons given for caution were plausible.
Motivazione estratta
The complaint merely contrasted its own reading of the testimony with that of the cantonal court. Given the witness's role as representative of C.________ AG and that company’s interest in shifting payment to the respondent, the appellate court could reasonably require corroboration.
