Much has been researched, written about, and subjected to public enquiry with respect to the content of Australian family law arrangements. This study adds to current understanding by the examination of the records of all successful appeals of parenting orders under the recently adopted regime of the Federal Circuit and Family Court of Australia Division 1 Appellate Jurisdiction. Drawing on transcripts from this Court to the date of writing, 35% of applications to appeal parenting orders were successful in being granted a rehearing or variation by the Appellate Jurisdiction. It is these cases which form the basis for this analysis. Employing an inductive thematic analysis, it has been possible to identify the pattern of circumstances most likely to lead to the compromise of the delivery of the declared principles of clear, predictable, and accessible law. Learning from the record of successful appeals, it becomes evident that the Appeals Court plays a relatively unappreciated critical role in identifying the context and nature of risks in the delivery of these core principles and what should be a central focus for attention.
