This article describes the development of an online decision support guide to relevant case law decisions for owners corporation disputes in Victoria, Australia. The rate of growth of owners corporations (also known as body corporate or strata title properties) has increased significantly in the last two decades. Because of this growth, and the need to manage a rapidly expanding population, the governance and management of these entities has become an important concern for government, particularly regarding managing conflict, yet existing legal remedies are an inadequate way of responding to many of these disputes. The online system aims to provide negotiation decision support for relevant case law decisions determined by the Victorian Civil and Administrative Appeals Tribunal to help guide disputants through the grievance process.
