THE HAGUE, Netherlands (AP) — Former Bosnian Serb President Radovan Karadzic has filed a lengthy appeal against his conviction in March on genocide and other charges, arguing that he did not receive a fair trial and that United Nations judges made a string of mistakes when reaching the guilty verdicts.

Karadzic on Friday filed an appeal listing 50 alleged errors that, he argues, amount to a miscarriage of justice.

The appeal argues that the errors, "violated the presumption of innocence, created an unmanageable trial, and made a fair trial impossible."

The International Criminal Tribunal for the Former Yugoslavia sentenced 71-year-old Karadzic to 40 years imprisonment for masterminding atrocities by Bosnian Serb forces throughout the 1992-95 war that killed some 100,000 people.

Karadzic, who always maintained his innocence, is seeking acquittal or a new trial.
