The results of the investigation were cited especially by the Polisario Front and its Algerian backers as supportive of their argument, but the debate was largely submerged by the presentation of the opinion of the International Court of Justice on October 16. The court argued that while there were historical ties between both Mauritania and Morocco to the tribes and lands of Spanish Sahara, neither country's claim sufficed to grant it ownership of the territory. The court also ruled that the Sahrawis possessed a right of self-determination, meaning that any solution to the problem of the status of Spanish Sahara had to be approved by the Sahrawi public.
