US ratification of UNCLOS will not subject military to rule by international tribunals
Will accession subject the U.S. military to the jurisdiction of international courts? Again, the answer is no. The Convention specifically permits nations to exempt from international dispute resolution, “disputes concerning military activities, including military activities by government vessels and aircraft.” State Parties individually determine what constitute “military activities.” Current and former leadership within the U.S. government have given repeated assurances that the United States would take full advantage of this clause in its accession documents to exempt U.S. military activities and protect them from the jurisdiction of international courts and tribunals. In fact, this is specifically outlined in this Committee’s Draft Resolution of Advice and Consent of 2007 and continues to be supported by the current Administration.
Some opponents of UNCLOS have argued that by ratifying UNCLOS, U.S. military forces could be subject to adverse ruling by international tribunals through the dispute resolution mechanisms of the treaty. However, the U.S. defense department has reviewed the relevant law and has found no undue liability risk to U.S. forces. Furthermore, in the Senate's Advice and Consent resolution that would ratify UNCLOS, the U.S. has taken advantage of article 298(1) in UNCLOS to exempt itself from all dispute settlement.
