This volume provides a general account of the making, interpretation and application of the various types of legislation applicable to the UK. Legislation is dealt with from inception, through formulation, drafting and enactment, to interpretation and impact. The text of this edition has been revised to include discussions of the role of Parliament, government and the courts in the enterprise of legislation. The authority of the various types of legislation in relation to each other and to other sources of law is also considered. The treatment of interpretation is examined to take account of recent literature and case law in the interpretation of statutes. A new section has been included on statutory codes of practice.
