The meaning of insolvency matters for the type of legal rule. In general terms insolvency has, since the earliest legislation, depended upon inability to pay debts.[24] The concept is embodied in the Insolvency Act 1986 section 122(1)(f) which states that a court may grant a petition for a company to be wound-up if "the company is unable to pay its debts". This general phrase is, however, given particular definitions depending on the rules for which insolvency is relevant. First, the "cash flow" test for insolvency represented under section 123(1)(e) is that a company is insolvent if "the company is unable to pay its debts as they fall due". This is the main test used for most rules. It guides a court in granting a winding-up order or appoints an administrator.[25] The cash flow test also guides a court in declaring transactions by a company to be avoided on the ground they were at an undervalue, were an unlawful preference or created a floating charge for insufficient consideration.[26] The cash flow test is said to be based on a "commercial view" of insolvency, as opposed to a rigid legalistic view. In Re Cheyne Finance plc,[27] involving a structured investment vehicle, Briggs J held that a court could take into account debts that would become payable in the near future, and perhaps further ahead, and whether paying those debts was likely. Creditors may, however, find it difficult to prove in the abstract that a company is unable to pay its debts as they fall due. Because of this, section 122(1)(a) contains a specific test for insolvency. If a company owes an undisputed debt to a creditor of more than £750, the creditor sends a written demand, but after three weeks the sum is not forthcoming, this is evidence that a company is insolvent. In Cornhill Insurance plc v Improvement Services Ltd[28] a small business was owed money, the debt undisputed, by Cornhil Insurance. The solicitors had repeatedly requested payment, but none had come. They presented a winding up petition in the Chancery Court for the company. Cornhill Insurance's solicitors rushed to get an injunction, arguing that there was no evidence at all that their multi-million business had any financial difficulties. Harman J refused to continue the injunction noting that, if the insurance company had "chosen" not to pay, a creditor was also entitled to choose to present a winding up petition when a debt is undisputed on substantial grounds.[29]
