Ngolo 's constituency , the first constituency of Ouenzé , was among those areas of Brazzaville affected by the March 2012 explosions at a munitions dump , which killed hundreds of people . As a consequence , voting was not held in his constituency , as well as two other constituencies , at the time of the July &ndash; August 2012 parliamentary election . On 17 August 2012 , the parliamentary terms of Ngolo and the other two deputies were extended by the Constitutional Court until such time as voting could be held . The ruling was in line with a constitutional provision allowing for such extensions when voting could not be properly held due to " exceptionally serious circumstances "
