In the years to come the international legal order will have to face a broad range of challenges, of both an institutional and substantive nature. That is precisely the focus of this collective volume written by contributors from Flanders and the Netherlands. Although they are specialists in different fields of international law, what unites them is their position as Emeritus professors, with long and respected careers and a wealth of experience and insight. Their brief was to reflect - from their silver perspective - on the future of their respective fields and the most pressing challenges that lie ahead for them. The result is a fascinating, thought-provoking and above all original collection, offering the reader the benefit of the collective wisdom of this group of eminent "silver" scholars.
