At common law, a surety's right of recourse against the principal debtor arises only when the surety has made payment to the creditor, not when the creditor makes demand or when the principal debtor's liability to the creditor crystallizes. Section 154(2) of the Companies Act 71 of 2008 does not, expressly or by necessary implication, alter this common law principle. Therefore, a debt based on a surety's right of recourse that arises from payment made after the commencement and approval of a business rescue plan is not a debt 'owed by the company immediately before the beginning of the business rescue process' within the meaning of section 154(2), and creditors may enforce such debts notwithstanding that they are not provided for in the business rescue plan.
