Senior Fellow in Constitutional Jurisprudence, Independence Institute
Professor Robert G. Natelson is a constitutional scholar and author.
Rob’s constitutional scholarship has been cited repeatedly by justices and parties at the U.S. Supreme Court—as well as by federal appeals courts, and at least 18 state supreme courts.
Rob’s research into the Constitution’s original meaning has carried him to libraries throughout the United States and in Britain, including four months at Oxford University. His books and articles span many different parts of the Constitution, including groundbreaking studies of the Necessary and Proper Clause, the Indian Commerce Clause, federalism, Founding-Era interpretation, regulation of elections, and the amendment process of Article V. He created the first-ever online bibliography for 18th century materials used in constitutional research. He is a contributing author to the Encyclopedia of the Supreme Court of the United States (on Magna Carta). He contributed eight essays to the third edition of the Heritage Guide to the Constitution: five on the amendment procedure and one each on the Guarantee Clause, the Postal Clause, and the Recess Appointments Clause.
U.S. Supreme Court justices have relied explicitly on Rob’s research in 41 citations in 13 separate cases.
