The Supreme Court's Federal Tax Jurisprudence occupies an original space previously not attempted by any other writer in the area of tax law publishing. Using the federal tax opinions of the United States Supreme Court as its primary guide, this book analyzes how federal tax laws have been applied in practice, with special emphasis on statutory interpretation and fact finding. The author demonstrates how the body of Supreme Court tax opinions is sufficiently large (nearly 1,000 opinions) to provide an authoritative guide to many of the most difficult questions of Internal Revenue Code application, including Chevron deference, economic substance, substance over form, step transactions, interpretative presumptions and maxims, tax avoidance, equity in the tax law, and more.
