On December 5, 2006, ACS and the Federalist Society co-sponsored A Conversation on the Constitution: Perspectives from Active Liberty and A Matter of Interpretation with U.S. Supreme Court Associate Justices Stephen Breyer and Antonin Scalia. In this conversation, which was moderated by ABC News Legal Correspondent Jan Crawford Greenburg the Justices discussed the interpretive methodologies described in their books, and conversed on the Constitution itself. Nine hundred lawyers, law students, judges and journalists attended the event.
