The relationship between corporate law and corporate practice is complex. So too is the relationship between the different types of corporate law rules — from primary and delegated legislation, through listing rules and ASIC orders to corporate constitutions. Corporate lawyers tend to respond to this complexity and diversity by implicit understanding than by conceptual framework. This article offers one way of conceptualising the complexity of corporate law rules and their relationship to corporate practice. Drawing on Boaventura de Sousa Santos’ influential 1987 article ‘Law: A Map of Misreading. Toward a Postmodern Conception of Law’, the article looks to cartography as an unexpected source of ideas to assist in understanding the shape of modern corporate law rules.
