He served in the government of Congo-Brazzaville as Minister of Water, Forests, and Fishing during the 1990s, and he has been President of Action for the Rebirth of Congo (ARC), a political party, since 2008.
[1][2][3] He was Co-Director of the Forester Center for Training and Demonstration, a United Nations Development Programme (UNDP) project based in Mossendjo, from 1967 to 1969.
[7] Although the opposition furiously contested the official results of the 1993 election, President Lissouba proceeded to appoint a new government based on his parliamentary majority on 23 June 1993.
[10] In February 2009, together with 17 other opposition leaders, Ngouolali signed an agreement on the creation of a front intended to defeat President Sassou Nguesso in the July 2009 presidential election.
However, in a ruling on 18 June 2009, the Constitutional Court rejected Ngouolali's candidacy on the grounds that he had provided a post office box number instead of identifying a place of residence.
[12] Speaking on 23 June 2009, Ngouolali complained that he did not understand why his candidate application was rejected, noting that he had documentation demonstrating his residency in Brazzaville.
According to Ngouolali, an official had told him that, because he lived in an apartment, it would be acceptable for him to list a post office box instead of a street address.
