Former Bosnian Serb leader Radovan Karadzic will be taking the courtroom floor again when he contests his conviction for genocide and a 40-year prison sentence before UN appeals judges.
Karadzic was convicted in 2016 for some of the worst war crimes committed as the former Yugoslavia broke apart, including the 1995 Srebrenica massacre.
Now 72, Karadzic was found guilty on 10 counts of genocide, war crimes and crimes against humanity for the brutal campaign of ethnic cleansing in Bosnia he oversaw as the president of the breakaway Bosnian Serb Republic.
He has filed 50 grounds of appeal in an effort to overturn his conviction and sentence. Acting as his own lawyer, with the help of legal counsel, he has asked for the entire judgement to be reversed and for a "new and fair trial" to be ordered.
His conviction was handed down by UN judges at the International Criminal Tribunal for the former Yugoslavia (ICTY) which said he was "at the apex of power" of the Bosnian Serb military and political hierarchy when atrocities were committed by his troops.
