Gary Born delivers his famous “Is Winter Coming?” address. Adapting, freely, themes from the Game of Thrones TV series, Professor Born argues that international arbitration has enjoyed “a long golden summer when everything went right” but that there are signs that “winter may be coming.” Despite the vital role that international arbitration has played over the past century in facilitating cross-border trade and commerce and in advancing the rule of law in international life, those achievements are threatened by a metaphorical army of critics. Professor Born challenges those critics, who seek to dismantle the legal framework for international arbitration, as betraying central aspirations of international law and threatening the material contributions of cross-border trade over the past 50 years.
