Book excerpt: "The modern principle is the official approach to statutory interpretation in Canada and is the foundation for the structure of this text. The modern principle focuses on the language of a statutory provision in light of its purpose, intent and context, and Hutchison devotes separate chapters to each of these aspects of statutory interpretation. The Fundamentals of Statutory Interpretation also critiques the various facets of the modern principle with a view to help identify more convincing interpretations of legislative intent. In addition, it tackles complicated issues concerning both the temporal application of statutes, such as retroactivity and retrospectivity, and when legislation may interfere with "vested rights.""--Publisher's website.
