Dear colleagues I just decided to re-join this very usefull list after several years. My name is Nicolas Boeglin Naumovic. I´m a French lawyer (I got my PHD at the University of Paris II, with a thesis presented in 1996 on "The land boundary between Costa Rica and Nicaragua" under the supervision of "mon regretté maître", Professor Daniel Bardonnet. I live in Costa Rica since 1992, and teach public international law ate the Law Faculty of the "Universidad de Costa Rica". I have concentred my researches on rivers boundaries (my last contribution entitled International Water Courses as Boundaries" (in French, " De l´usage des cours d´eau internationaux comme rivières") can be found in the book published by the Hague Academy of Internationa Law, Water Resources and International Law (Boisson de Chazournes L and Salman S.M Editors).Martinus Nijoff Pub, 2005, pp133-165). I follow in my reserachs very closely the development of many cases presented by latinamerican States before the International Court of Justice, which are: Nicaragua c. Honduras (just resolved by ICJ last december) Nicaragua c. Colombia (pending) Costa Rica c. Nicaragua (pending) Argentina c. Uruguay (pending) And recently, Peru c. Chile (request presented 2 weeks ago) Just to note that it is the firts time in the history of the ICJ that so many cases involve latinamerican States. A great record to keep in mind !!! There are still some unresolved question of martime delimitation in the Caribbean that possibly will improve the number of cases...Who knows. A very short articel published in La Nacion (Costa Rica ) on this issue can be read (in Spanish) at: http://www.nacion.com/ln_ee/2005/noviembre/20/opinion5.html I hope to share with all members of this very prestigious list experiences and know-how on how establish "une bonne frontière" following the words of Paul Geouffre de La Pradelle in 1928.
