Nonetheless, in view of its desire to be transparent in its activities, the commission invites political parties to participate in its working sessions when carrying out this particular mission. It ensures recruitment and training of staff of the polling stations and those hired for the election processes. The commission is equally responsible for the movement of the election materials and ballot papers at the end of the ballot. It has the power to announce the results of the presidential election. More specifically, the chairman of the commission carries out such a formality. As for other elections the results can be announced by other individuals so designated by the commission, whether at the zonal level or an entirely new voting centre. The commission accredits election observers and their papers if there is need for general information necessary for the accomplishment of their mission. The commission equally has the duty of sourcing and distributing materials and financial resources allocated to political parties by the Ghanaian government. The distribution may not be rigorously even but it may be subjected to the previous performances of the parties concerned. The Ghanaian electoral commission has the power to invalidate election results before their announcement or publication. The commission investigates allegations of irregularities when brought to its notice and nullifies the results if these allegations are established. On the other hand, when the allegations are made after the announcement and publication of the provisional results, only the Supreme Court of Ghana can invalidate the electoral results. In either of these cases, the annulment of one election presupposes the organization of a new one. 69
