Acknowledgment of Debt vs. Condition Precedent in Repayment Obligation

The case involved a dispute over whether a party, who had signed a document acknowledging a debt and promising repayment on specific installment dates, could later argue that the underlying agreement was subject to a condition precedent regarding the delivery of goods. The Court of Cassation quashed the lower court's decision, reasoning that the written acknowledgment of the debt and the explicit schedule for repayment constituted an unconditional promise to pay, meaning the debtor could not later rely on an unfulfilled condition from the original contract that was not incorporated into the acknowledgment document as a suspensive condition for payment.
