This unit builds upon the introduction to statutory interpretation undertaken in other law units. This unit recognizes statutory interpretation as a distinct body of law different from the principles relevant to the interpretation of non statutory instruments such as contracts, and the central role of legislation in the practice of law. This unit also recognizes the role of statutory interpretation in its presumption against interference with fundamental common law and human rights. The creation of legislation is considered together with the role of Western Australian and Federal interpretation legislation. Context and purpose is considered, together with the notion of Parliament’s intention, the use of interpretative techniques and the use of intrinsic and extrinsic materials.  Students explore the task of interpreting legislative provisions relevant to a legal problem through application of the various recognized aids to statutory interpretation, traditional common law approaches and statutory presumptions, with a practical focus. The unit also considers special interpretative issues, including retrospectivity.
