The election was contested by four candidates; incumbent President Miguel Trovoada, former President Manuel Pinto da Costa, Alda Bandeira, a former Foreign Minister, and former Prime Minister Carlos da Graça.
[2] Despite being declared generally free and fair by international and domestic observers, da Costa, who had initially acknowledged Trovoada's victory, contested the results of the election, claiming that irregularities had occurred in the registration process.
The National Electoral Commission acknowledged that there were minor discrepancies in the registration process and in voter rolls but determined that these were insufficient to call the results into question.
In early August the Supreme Court declared that it was unable to adjudicate on the appeal made by da Costa, and recommended that the government seek international legal arbitration.
However, on 20 August da Costa withdrew his challenge and Trovoada was confirmed as president.
