Ong on Equity is a substantial and sophisticated work from Professor Denis Ong, author of the acclaimed commentary: Trusts Law in Australia, now in its third edition. Ong on Equity analyses in detail relevant cases from all the Australian and from international jurisdictions and thoroughly reviews all aspects of judicial decision making. Importantly, Professor Ong considers unanswered questions as they arise in judicial reasoning in an incisive and learned style and offers fresh insights and thoughtful scholarly analysis in respect of each of the topics comprehensively covered in this volume.

Trusts Law in Australia, now in its third edition, provides a comprehensive and scholarly analysis of modern trusts law. The structure is unchanged from previous editions and the 12 chapters cover all the topics expected of a book on the law of trusts express trusts, charitable trusts, voluntary trusts, resulting trusts, constructive trusts, writing and related requirements, the rules against perpetuities and accumulations, life tenants, remaindermen, tracing, and the duties, liabilities, powers, rights, appointments, retirement and removal of trustees. Professor Denis Onga's invaluable and important analysis addresses conceptual anomalies in the law, and interprets and critiques a large number of judicial decisions. Each chapter finishes with a summary of relevant legal principles, making the book unusually accessible. Since the publication of the second edition in 2003, a number of significant cases have been decided in the area of trusts: On the subject of writing requirements, the following cases have appeared: Theodore v Mistford Pty Ltd (2005) 221 CLR 612; Halloran v Minister Administering National Parks and Wildlife Act 1974 (2006) 80 ALJR 519; and Khoury v Khouri (2006) 66 NSWLR 241. Blackett v Darcy (2005) 62 NSWLR 392 has refined the Principle in Strong v Bird (1874) LR 18 Eq 315. Thirdly, the courts power to authorise expedient decisions, conferred under s81 of the Trustee Act 1925 (NSW), was analysed in Arakella Pty Ltd v Paton (2004) 60 NSWLR 334. In the area of proprietary estoppel there are the two not immediately reconcilable decisions in Sullivan v Sullivan [2006] NSWCA 312 and Donis v Donis [2007] VSCA 89. Most importantly, in the areas of liability commonly called knowing assistance and knowing receipt, the High Court has handed down its decision in Farah Constructions Pty Ltd v Say-Dee Pty Ltd [2007] HCA 22.

Ong on Rescission is Professor Denis SK Ong's fifth treatise in the field of equity. With its rigorous, yet accessible, approach to this complex area of law Ong on Rescission is a perfect supplement to his earlier acclaimed works: Trusts Law in Australia (now in its 4th edition), Ong on Equity, Ong on Specific Performance and Ong on Subrogation. The text offers a thorough study of rescission ab initio both at common law and in equity. As in his earlier works, the book offers a succinct exposition of all the key relevant principles of law, facilitated by a careful, and on occasion critical, analysis of all the leading authorities. To assist the reader, the essential passages of judgments under consideration are reproduced.
