Territorial Extent and Devolution Codification of common law rules and equitable principles
305.Codification is not a matter of transposing wording taken from judgments into legislative propositions. Judgments are, of necessity, directed at particular cases. Even when they appear to state general principles, they will rarely be exhaustive. They will be the application of (perhaps unstated) general principles to particular facts. In the company law field, the principles being applied will frequently be taken from other areas, in particular trusts and agency. It is important that these connections are not lost and that company law may continue to reflect developments elsewhere. Frequently the courts may formulate the same idea in different ways. In contrast legislation is formal. It is not easy to reconcile these two approaches but the draft sections seek to balance precision against the need for continued flexibility and development. In particular:
	subsection (3) of section 170 provides that the statutory duties are based on, and have effect in place of, certain common law rules and equitable principles;
	subsection (4) of section 170 provides that the general duties should be interpreted and applied in the same way as common law rules and equitable principles. The courts should interpret and develop the general duties in a way that reflects the nature of the rules and principles they replace;
	subsection (4) of section 170 also provides when interpreting and applying the statutory duties, regard should be had to the common law rules and equitable principles which the general duties replace; thus developments in the law of trusts and agency should be reflected in the interpretation and application of the duties;
	section 178 provides that the civil consequences of breach (or threatened breach) of the statutory duties are the same as would apply if the corresponding common law rule or equitable principle applied. It also makes clear that the statutory duties are to be regarded as fiduciary, with the exception of the duty to exercise reasonable care skill and diligence which is not under the present law regarded as a fiduciary duty.
306.The statutory duties do not cover all the duties that a director may owe to the company. Many duties are imposed elsewhere in legislation, such as the duty to file accounts and reports with the registrar of companies (section 441). Other duties remain uncodified, such as any duty to consider the interests of creditors in times of threatened insolvency.
