David speaks and writes regularly on class action issues.  He has presented to the American Bar Association (ABA), the Federation of Defense and Corporate Counsel, the Product Liability Advisory Group and others on consumer class actions.  David has served the courts through the Civil Litigation Subcommittee of the California Judicial Council, on special committees formed by the state courts to address toxic tort litigation, and as a member of the ABA’s American Jury Project.
