This volume analyses corporate insolvency law as a coherent whole, stemming from common fundamental principles and amenable to being justified or criticised on that basis. The author explains why consistency of principle must be sought and how it might be found in the relevant statutory and case law. He then constructs an egalitarian theory for the analysis of corporate insolvency law, based on the premise that all the parties affected by this law are to be treated as equals. He argues that this theory can reconcile the dictates of fairness with the demands of economic efficiency.The theory is employed to analyse some of the most important aspects of insolvency law. Why should the individualistic method of enforcing claims against solvent companies give way to a collective method during insolvency? Why are there different formal mechanisms for dealing with troubled companies? What role does the pari passu principle play in the distribution of an insolvent company s assets? The controversial issues of whether and when secured creditors should be accorded priority over others receive detailed consideration. The functional role of the floating charge and its relationship with receivership are also analysed in this context. The many questions relating to the operation of the new administration procedure introduced by the Enterprise Act 2002 are considered in the light of principle. The book also analyses the role of the wrongful trading provisions. It examines, finally, why insolvency law objects to certain transactions at an undervalue and those having a preferential effect.This volume aims to enhance understanding of this important branch of the law, and to suggest principled solutions to problems which have not yet received judicial attention.
