In March 2005, the Security Council formally referred the situation in Darfur to the Prosecutor of the International Criminal Court, taking into account the Commission report but without mentioning any specific crimes. Two permanent members of the Security Council, the United States and China, abstained from the vote on the referral resolution. As of his fourth report to the Security Council, the Prosecutor has found "reasonable grounds to believe that the individuals identified [in the UN Security Council Resolution 1593] have committed crimes against humanity and war crimes," but did not find sufficient evidence to prosecute for genocide.
Is there an answer to this question (If it cannot be answered, say "unanswerable"): When did the Security Council formally refer the situation in Darfur to China?
unanswerable
