In 1992 Italian judge Giuseppe Pittitto started a criminal trial after a complaint against suspected Slav criminals of war. Oscar Piskulic and Ivan Motika were both principal accused but they were discharged because territorial jurisdiction was rejected and they received acquittal under the amnesty of 1959. In 1997 some Italian deputies pressed their government for extradition of suspected Slav criminals but diplomatic problems stopped Italian action. All Italian historians consider Josip Broz Tito the chief of Slav criminals, but his corpse still stays in a mausoleum.
