Filmmaker Emir Kusturica announced an initiative to hold a ceremony on 28 June 2014, in which a re-trial of Gavrilo Princip would be started. The motivation behind the initiative was that Austria-Hungary never ratified the annexation of Bosnia and Herzegovina, and that a verdict of high treason therefore should be considered illegal. "It was a political murder, but definitely not high treason. If Princip was convicted of murder, it wouldn't have been possible to sentence him to lifetime imprisonment", Kusturica commented. Further, he will exhibit letters written by Oskar Potiorek, and argues that they prove that a war was planned long before the Sarajevo Assassination.
