I am indebted to my advisor, Professor Frank P. Grad, whose advice and encouragement were invaluable. He made my task all the more bearable, with wide-ranging discussions on legal and other matters, while nudging me to completion. Particular thanks should also be given to Professors Oscar Schachter, Bradley Karkkainen, Michael Young, and George Pring whose comments were most helpful. I have also benefitted from discussions of various aspects of the work with Professors Daniel Magraw and Gunther Handl, Ambassador Bjoernar Utheim and Carole Lindsay, attorney-at-law.
As most of the research was done while living in Boulder, Colorado, a special thank you goes to the faculty, staff, and students of the University of Colorado, School of Law. Being an adjunct instructor at the Law School and a Fellow at the Natural Resources Law Center enabled me to make many good contacts leading to more useful materials for research. The assistance of Jane Thompson, Leanne Walther, Michael Fontenot, Georgia Briscoe, and Diana Garry was very helpful. My gratitude also goes to Diana Stahl for getting the manuscript in camera-ready form. The assistance of William Shapiro and Stephen Fauver was also most helpful.
A special thank you also goes to my parents Stein and Louise Halvorssen, my sister Christine Cohen, and Rafael and Betty Castillo, for always being supportive and supplying me with articles for research. Maria Isabel Fleury and Andres Halvorssen also provided invaluable assistance. My children, Anita Louise and Rafael Michael, also deserve a thank you for being patient while Mamy was working late. Above all, I am grateful to my husband, Rafael E. Castillo, for his good ideas and for keeping me going. This book is dedicated to him.
