The study highlights the Court's important decisions on issues ranging from the scope and legitimacy of judicial review itself to civil rights, censorship, the rights of privacy, separation of church and State, and the powers of the President and Congress to conduct foreign affairs. The author admires the work of John Marshall but critically reviews the mixed achievements of Marshall's successor, Roger Taney, author of the infamous Dred Scott opinion, which upheld the legitimacy of slavery. The book sharply criticizes the Court's "formalist" era in the early 20th century, when judicial obstructionists are perceived as shielding a wealthy minority from the effects of democratic politics. The book underscores the importance of disagreements over just what law is and over the Court's role in interpreting that law, thus broadening the context for current debates about the Constitution and efforts to establish what some have called a "jurisprudence of original intention."
