“As I have mentioned, there is a discretion even if there is an arguable case, but it seems to me that unless there are special circumstances such as other creditors who have undoubted debts, or clear other evidence of insolvency, or facts such as were before the Court of Appeal in Askew v Peter Dominic Ltd[1997] BPIR 163 , namely that the debt in question was not challenged, then it seems to me, save in exceptional circumstances, that it must be right not to uphold a bankruptcy order.”
