evidence: When CPA negotiators first addressed the matter of Abyei, the issue was further complicated by the fact that it was considered to be an oil-rich territory. The Abyei Boundary Commission, set up in 2005 to demarcate the territory of the nine Dinka chiefdoms, had included the Heglig oil fields in Abyei’s territory. This inclusion was a blow to Khartoum because in the short run, Abyei would keep more of the oil revenue it produced, and in the long run, the South might keep it all if Abyei voted for secession, as appeared likely. Khartoum thus appealed the decision of the Abyei Commission and the issue was taken up by the Permanent Court of Arbitration in The Hague, which in 2009 ruled that Heglig was not historically part of the old chiefdoms’ territory but was located in Kordofan state. The oil town was thus taken from Abyei and placed within South Kordofan’s borders, making it a contested hot spot that both North and South Sudan claim to be a part of their territories.
