Singapore’s common law-origin corporate law regime ranks highly on corporate law and governance indices and is administered in part by superior courts served by judges with significant commercial expertise. Part of the Singapore Academy of Law’s Annual Review of Cases, this Paper reviews decisions of the Singapore superior courts (comprising the High Court and the Court of Appeal) decided in 2017. The cases reviewed feature a wide range of issues with domestic and international significance, including private enforcement of director duties, corporate attribution, corporate veil piercing and shareholder disputes. This Annual Review will be useful for academics and lawyers who wish to stay up to date on legal developments in a leading Asian, common law jurisdiction, and on the reception of landmark common law cases in a leading Anglo-Commonwealth jurisdiction.
