I am honoured and humbled to have such an eminent panel engage with my book, Proportionality and Facts in Constitutional Adjudication. As I will explain below, the motivations for this book stemmed in part from my time as a practising government lawyer, so I’m particularly delighted that this book forum includes two practitioners of public law, along with a leading comparative constitutional law scholar. Each panellist has engaged thoughtfully with the substance of the book and has raised a number of distinct issues. In this post I will explain the motivations behind the book and its main themes and findings, as well as responding to the helpful contributions from the three panellists. In doing so I will sketch some future directions about the ongoing conversation about facts in proportionality reasoning (and public law more generally).

Dr Anne Carter’s Proportionality and Facts in Constitutional Adjudication is a timely and welcome addition to the perpetually growing commentary concerning the advent of structured proportionality in the High Court’s jurisprudence of the implied freedom of political communication.

As Dr Carter notes throughout the book , a bare majority of the High Court in McCloy v New South Wales (2015) 257 CLR 178 dramatically changed the approach to testing proportionality in respect of the implied freedom by adopting a structured, multi-faceted approach to proportionality testing, effectively in lieu of the prior verbal formulation from Lange v Australian Broadcasting Corporation (1997) 189 CLR 520. given how extensively it changed the approach to the implied freedom. McCloy heralded a new wave of both academic commentary and case-law about the merits and application of the new formulation. This book does an excellent job at building out the former and offering guidance for the latter in respect of the use of facts in the new world of implied freedom proportionality testing.

Dr Anne Carter’s new book, Proportionality and Facts in Constitutional Adjudication, makes a substantial and timely contribution to our understanding of a range of issues emerging in the burgeoning field of proportionality litigation. The focus of the book is on sources of evidence, burdens of proof and aspects of procedure. However, the book’s real strength is that it locates what are ultimately practical litigious issues within a sophisticated account of the evolution of the implied freedom of political communication in Australia and an appreciation of comparative approaches drawn from jurisdictions which have long wrestled with these issues.

Proportionality analysis is ultimately deeply fact dependent. It depends on an assessment of the suitability of laws for achieving their purposes – a question of basic logic and social fact. It further requires an assessment of whether a law is necessary, or could achieve its objective through some hypothetical, less restrictive alternative, and is 'adequate in the balance', namely achieves greater benefits than costs, from a constitutional perspective.

Anne Carter notes in her important new book that these are all arguably 'legislative' rather than 'adjudicative' facts, but also distinct in nature and scope. As the High Court has indicated, each calls for different sources of evidence, and procedures and rules governing their use. Yet to date, the constitutional law-fact nexus has attracted only limited attention in Australia. Carter’s book therefore makes an important contribution to the literature on this question. It provides a nuanced survey of the procedural challenges and complexities facing the High Court in this context, and offers tentative, well-reasoned potential solutions, informed by comparative experience.

The Australian climate litigation movement has recently made significant inroads into the field of negligence. In Sharma v Minister for the Environment (2021) (Sharma), the Federal Court held that the Minister for the Environment owes a duty to Australian children to take reasonable care when considering approval of a coal …

Shipra Chordia’s excellent book, Proportionality in Australian Constitutional Law, is a fine contribution to this difficult and developing area. As Sir Anthony Mason observes in his foreword, it is “an important addition to the Australian Constitutional Law Bookshelf” (at vi). Notably, the High Court has already begun to engage with Dr Chordia’s work …

Proportionality is a vexed topic in Australian constitutional law. On the one hand, the High Court has for many years relied upon forms of proportionality to characterise laws enacted with respect to purposive and incidental law-making powers, and to determine the validity of laws burdening constitutional limits. On the other hand, …

The closure of international borders has been a key pillar of Australia’s response to the COVID-19 crisis. Australia’s strategy to “aggressively suppress” (in practice, eliminate) COVID-19 within its borders has relied heavily on restrictive measures, including flight caps and travel bans, to limit the importation of the …
