a. The Supreme Court of NSW is sitting on a case where there is an issue about whether a former Chief Executive Officer of an Australian bank had breached his fiduciary duties to the company. Considering that a similar legal question has not been decided by the Supreme Court of NSW or the High Court of Australia, justices are considering whether they should decide the case based on a decision on similar issues made by the Victoria Supreme Court or whether the Court should follow a judgment decided by the Supreme Court of Canada on similar facts. Which precedents must the Supreme Court of NSW follow?
