In a closely watched case, Textron Inc. has asked the U.S. Supreme Court to review a decision of the U.S. Court of Appeals for the First Circuit that dramatically narrowed the traditional scope of protection afforded under the “work-product privilege.” The First Circuit's decision, if allowed to stand, has significant implications for tax practitioners and their corporate clients, both in the federal and state arenas.

Lima, discuss the limitations of work-product privilege in different contexts and why the U.S. Supreme Court should grant review.
