Özet: A commercial mask supply company previously initiated enforcement proceedings for unpaid invoices against a client company. The defendant client company objected to the enforcement, stating that payments were made to a third-party intermediary. The first instance court ruled against the plaintiff, asserting a lack of definitive proof. The plaintiffs legal representative then filed an appeal, arguing that it is unlawful to prioritize the defendants defense of third-party payment over the official invoices as written evidence. The plaintiff contends that according to the principle of a prudent merchant, payment should have been made directly to the plaintiff company, and requested the reversal of the local courts decision.
