This publication has been the leading casebook in the field for 20 years. It is the most authoritative work available on this topic, extensively cited by the Supreme Court and other courts, and in the scholarly literature. With the retirement of Professor Wolk, the author team of Professors Langbein and Stabile is joined in the Fifth Edition by Professor David Pratt, a scholar of pension taxation. The Fifth edition adds coverage of several recent Supreme Court decisions and a number of recent lower court decisions as well as addressing recent changes affecting benefit plans, including the Pension Protection Act of 2006 and the effects of the current recession.
