Yesterday President Biden signed into law H.R.4250 (full text) which expands the Department of State War Crimes Rewards Program that allows the State Department to pay rewards to persons who furnish information leading to the arrest or conviction in any country, or by an international criminal tribunal, of any foreign national accused of war crimes, crimes against humanity, or genocide. Previously 22 USC §2708(b)(10) had a seemingly artificial limitation on when a reward could be paid. It was authorized only when the defendant was convicted of these crimes as defined by the statute setting up the international criminal tribunal involved. The new law expands this to allow rewards when the defendant is convicted in another country or by an international tribunal of war crimes, crimes against humanity or genocide as defined by "(A) the statute of such country or tribunal, as the case may be; or (B) United States law".
