Ivory Coast President Alassane Ouattara had requested the International Criminal Court to investigate the accusations of serious human rights crimes which were committed during the country's recent turmoil.
This had been because "Ivorian justice [was] not at this time best placed to reveal the most serious crimes", he had stated.
An estimated of 3,000 people had been killed during the four-month election dispute.
Over 25,000 people are still staying in the grounds of a church in the western city of Duekoue.
They stated that they are fearing for their safety because they belong to an ethnic group, the Guere.
After getting power, Ouattaran had made a promise that crimes committed by all sides during the dispute will get investigated.
ICC chief prosecutor named Luis Moreno-Ocampo had already stated that his office had been preparing to set forward a formal investigation into accused mass killings in Ivory Coast.
Many hundred people had been reported massacred in Duekoue during the unrest between Gbagbo and Ouattara supporters.
