In 1999, Bork wrote an essay about Thomas More and attacked jury nullification as a "pernicious practice". Bork once quoted More in summarizing his judicial philosophy. In 2003, he published "Coercing Virtue: The Worldwide Rule Of Judges", an American Enterprise Institute book that includes Bork's philosophical objections to the phenomenon of incorporating international ethical and legal guidelines into the fabric of domestic law. In particular, he focuses on problems he sees as inherent in the federal judiciary of three nations, Israel, Canada, and the United States—countries where he believes courts have exceeded their discretionary powers, and have discarded precedent and common law, and in their place substituted their own liberal judgment.
