The third edition of the manual of Marie-Laure Niboyet and Géraud Geouffre de la Pradelle (both professors at Paris Ouest Nanterre La Défense University) on the French conflict of laws was published earlier this fall.
In the French tradition, the book covers not only choice of law, jurisdiction and judgments, but also the law of citizenship and emmigration.
It is an excellent book. Marie-Laure Niboyet being one of the finest French scholars of international civil procedure, the book is especially comprehensive in this respect, discussing topics often neglected by many other books.
