This new book revises, and adds new foci, to the authors' predecessor casebook Government Contract Law: Cases and Materials (2d ed. 2004). It retains the core chapters for a syllabus on the basics of government contracting law. The authors update the core chapters with short, student-friendly, tightly-edited cases. A plurality of the book's cases dates from the 2000s, with most of the rest from the 1990s. These present current understandings of issues and doctrines in this rapidly evolving field. As new foci, the authors have greatly expanded the number of specialized chapters treating increasingly important topics. New chapters cover such fast-changing specialties as commercial and IDIQ contracting, intellectual property, health care, construction, government and contractor workforce, false claims and defective pricing, and government takings. Also, the book treats new procedures including protests of task order awards and claims for government breaches of contract. Dozens of fresh notes by the authors cover recent developments such as government acquisition of property rights in software, and contracting in the Afghan and Iraq wars. Tiefer and Shook bring academic and practitioner experience and expertise to their treatment of government contract law.
