Book excerpt: This book is a timely and useful supplement to such basic courses as Professional Responsibility, business enterprises, and even commercial law. It may also be assigned in such classes as securities regulation, business/corporate ethics, and inside counsel. Indeed, a course in ethics for the business attorney may adopt this book as its primary source. The book uses the problem method to provide a concrete mode of analysis. This method works nicely to bring reality to the scene and energize the students. Rather than discussing abstract issues in a vacuum, the problem method in this setting enables students to apply the book's materials to real situations. The book contains material devoted, for example, to the following subjects: 1) the role of the business lawyer; 2) identifying counsel's client; 3) client-fraud dilemmas; 4) conflicts of interest; 5) role of in-house counsel; 6) related party transactions; 7) internal investigations; and 8) basics of business practice.
