Presidential authority to use troops without congressional consultation. Whether the war powers resolution should be repealed. The extent to which international human rights must be respected as a matter of domestic law, and to what extent courts should be involved in such matters. These and other issues are part of a long-simmering constitutional struggle for control of American foreign policy. The roles of Congress, the courts and the president in constructing foreign policy will be examined during a daylong symposium to be held at the University of California, Davis, law school Friday, Oct. 11. Scholars from across the country will examine how constitutional principles have changed during the past two and a half decades. As a basis for discussion, the speakers will focus on a 1972 book by internationally known legal scholar and Columbia University professor emeritus Louis Henkin, "Foreign Affairs and the Constitution." The symposium begins at 8:30 a.m. and concludes in the late afternoon. The second edition of Henkin's book is being published this month, prompting the symposium, explains Michael Glennon, a UC Davis law professor and a conference organizer. "To paraphrase JFK, this may be the most illustrious group of foreign affairs scholars gathered at one luncheon since Lou Henkin dined alone," Glennon said. "It's a real honor for the university to serve as host. For many years significant international law events have been held on the East Coast. This event shows they can succeed on the West Coast, too." Among the academic speakers from UCLA, University of Pennsylvania, University of Wisconsin, Columbia University and Yale will be the former U.S. ambassador to Nepal, the former dean of the Stanford Law School and the former president of the American Civil Liberties Union. The scholars will present and discuss papers on the war powers, the appropriations power, the treaty power, judicial intervention or restraint, the constitutionality of U.S. participation in international organizations and the impact of U.S. foreign affairs on individual rights. The symposium is sponsored by the UC Davis law school, UC Davis Journal of International Law and Policy, and the American Society of International Law. The papers will be published in an upcoming issue of the Journal of International Law and Policy, founded by the late Theodore M. Pritikin, of the UC Davis law school class of 1994. The symposium is dedicated to Pritikin. Seating at the symposium is limited to 150 people, and the registration deadline is Friday, Sept. 27. All attendees must register.
