The so-called Quistclose trust probably represents the single most important application of equitable principles in commercial life. (Lord Millett in the foreword to this book). The decision of the House of Lords in Twinsectra v Yardley has refocused attention on the Quistclose trust.

The purpose of these essays is to explore the foundations of the trust and subject them to a searching analysis.
