Germany then modified its complaint in the case before the ICJ, alleging furthermore that the U.S. violated international law by failing to implement the provisional measures. In opposition to the German submissions, the United States argued that the Vienna Convention did not grant rights to individuals, only to states; that the convention was meant to be exercised subject to the laws of each state party, which in the case of the United States meant subject to the doctrine of procedural default; and that Germany was seeking to turn the ICJ into an international court of criminal appeal.
