Abstract
This paper discusses some of the practical difficulties confronting Jeff McMahan’s proposal of a jus ad bellum court of experts for deciding the justice of war, and recommends two revisions. First, following the earlier proposals of Vitoria, Suarez, and Grotius, leaders could have a say in appointing judges to the ad bellum court; second, the court could be an organ of the International Criminal Court. Though significant practical challenges remain, these revisions make McMahan’s proposal fairer to democratic governments, and give the court a better chance for successful implementation in the prevailing Westphalian system of state sovereignty.
