In early 2015, the High Court of Australia decided Cassegrain v Gerard Cassegrain & Co Pty Ltd , relating to the fraudulent registration of a joint tenancy under Torrens legislation. The Court unanimously criticised the methods employed by lower courts in interpreting New South Wales’ Torrens legislation (and its ‘protection of purchasers’ provision) and in determining the existence and scope of an agency relationship. However, the Court split on the question of whether an innocent joint tenant had their interest rendered defeasible by reason of their co-joint tenant’s fraud. This article reviews and analyses in particular the Court’s evaluation and treatment of the legal principles of joint tenancy. .

直到欺诈行为使我们分手：调和联合租赁与Cassegrain v Gerard Cassegrain＆Co Pty Ltd中的Torrens土地系统

2015年初，澳大利亚高等法院裁定Cassegrain诉Gerard Cassegrain＆Co Pty Ltd，涉及根据Torrens立法对联合租赁的欺诈性注册。法院一致批评下级法院在解释新南威尔士州的托伦斯法律（及其“保护购买者”规定）以及确定代理关系的存在和范围时所采用的方法。但是，法院就无辜的共同承租人是否由于共同共同承租人的欺诈行为而使其利益无法实现这一问题进行了辩论。本文特别回顾和分析了法院对共同租赁法律原则的评估和处理。。
