The purpose of the working group headed by Nzoungou was to "define the status of the rebel leader". Later, Nzoungou was appointed as President of the National Commission of the Fight Against Corruption, a body tasked with the implementation of government anti-corruption policies, on 29 August 2007. The 16 members of the Commission were sworn in at a ceremony in Brazzaville on 9 November 2007. On 9 December 2007, in a statement to mark the International Anti-Corruption Day, Nzoungou called for the Congolese people to battle corruption; echoing the words of President Denis Sassou Nguesso, he stressed that corruption was an obstacle to development. Nzoungou remained in his post as President of the National Commission for the Fight Against Corruption until he died in Paris on 7 September 2012; he was 74 years old.
