Professor Tan's monograph The Law of Agency, first published in 2010, forms part of Academy Publishing's 'Law Practice Series' which aims to publish seminal works on key subject areas in legal practice. It is encouraging, to this end, to see the law of agency take its rightful position in this cast, rather than simply being relegated to a sub-set of contract law (where it not infrequently resides in law school syllabi). There is much more, after all, to the law of agency than its common (but not invariable) contractual foundation; agency inhabits, and interacts with, other core areas within the modern law of obligations, including those sourced from tort, property and equity.
