In early July, for the first time, the Serbian parliament adopted a potentially important new law for prosecuting war criminals. The law creates a new post of war crimes prosecutor and identifies a district court in Belgrade to judge war crimes cases. Perhaps most important, the law includes provisions for witness protection - a major obstacle to trying war crimes cases in the past. HRW researcher Bogdan Ivanisevic says the Serbian government now needs to muster the political will to make the new law effective.
