Horvatic was speaking at the third symposium "The Hague Tribunal - A Joint Criminal Enterprise - What Is It?" which gathered legal experts, historians, academicians and members of the wartime government.
Horvatic said that Del Ponte had become an actively destructive element of international criminal justice because she was doing damage to the idea of it ensuring supranational justice and fairness for all countries and for each person.
According to him, the concept of a "joint criminal enterprise" was not part of international common law at a time crimes alleged in the indictments issued by the tribunal were committed, so that such accusations are in contravention of the principle of legality.
Actions by the chief prosecutor and her office, although not in accord with legal principles, are obviously in accord with their role and objectives regarding a political and historical "truth", which they try to achieve by abusing international criminal justice, Horvatic said.
If they even partly succeed in this abuse and if such "truths" become the basis of ICTY judgements, the truth about international criminal justice and the administration of international criminal law by the Hague tribunal will no doubt be a shameful part of the history of that law in the first decade of the 21st century, Horvatic concluded.
Josip Pecaric, a member of the Croatian Academy of Arts and Sciences, said that he regarded the tribunal's indictment for a joint criminal enterprise as a continuation of aggression against Croatia.
It is a criminal enterprise by Carla del Ponte and circles abroad and at home who agree with that, Pecaric said.
The symposium was moderated by former Supreme Court president and retired Constitutional Court judge Milan Vukovic, who announced the next meeting for December 7.
