Pre-existing disputes in operational debt are examined through the debtor's admissions, the running account, payment appropriation, and supporting evidence. The note states that where payments are not directed toward specific invoices, the operational creditor may appropriate them on a first-in-first-out basis. It further discusses that inconsistent positions on payment appropriation may engage the principle against approbating and reprobating, and that unsupported assertions of short supply, debit notes, deficiencies, or protected-period claims may not establish a genuine dispute. It also addresses the permissibility of placing additional documents, including communications and financier-related material, on record before a final insolvency order is passed.
