This class begins by conceptualising company and securities law in the former British enclaves in the Southern hemisphere in three ways. It first looks at the initial reception of UK law in the Southern hemisphere up until the adoption of the Company Act 1948 (UK). This part of the story is variously called, “transplanting”, “path dependence” or “diffusion”. Second, we look at the attempts to carve new pathways in the region that depart from UK law; here, Australia provides a striking example. Third, we look at the ways in which these jurisdictions have borrowed from and influenced each other. This process of “rediffusion” is particularly evident in Malaysia (influenced by modern Australian law) and small South Pacific jurisdictions that have adopted versions of New Zealand law. Hence, although the focus of the class is on Australian and New Zealand law, it will become apparent that an understanding of the law in these jurisdictions facilitates an understanding of the law in cognate jurisdictions such as Singapore, Malaysia and Hong Kong.
