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.

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.
