Kernrechtsfrage
Whether the appellate judgment was arbitrary in confirming the debt and lifting the objection despite the debtor's payment allocation theory.
Extrahierter Entscheid
The appellant failed to show arbitrariness; the cantonal courts could treat the remaining balance as due under the invoiced claims and reject the challenged payment-allocation argument.
Extrahierte Begründung
The appellant did not establish any specific federal norm violated and did not show that the factual findings about payment allocation were arbitrary.
