Helpful or hollow? Rethinking the interpretive role of Interpretation Acts

Abstract In the era of increasingly complex legislation, the issue of statutory interpretation is gaining prominence, raising important questions about the role and effectiveness of normative acts that seek to regulate interpretive practices. This article analyses the content of Interpretation Acts currently in force in selected common law jurisdictions—including Australia, Canada, New Zealand, Ireland, and the UK—with a focus on provisions that explicitly address interpretive issues. This article is divided into three parts. The first offers a general overview of interpretive provisions in Interpretation Acts, highlighting both their common regulatory areas and notable absences. The second examines substantive choices made within these Acts in response to key interpretive debates, with emphasis on the selected approach and use of extrinsic aids. The third section focuses on ambulatory provisions, a topic of growing significance in recent interpretive discourse. In this context, the article highlights Irish provisions, largely overlooked in discussions about interpretation in changing circumstances. The aim of the study is to assess the extent to which Interpretation Acts may influence interpretive practice. This article encourages further debate on the potential of these Acts to promote interpretive coherence and enhance the transparency of the interpretive process.
