In principle, the parliament’s control over the executive power is grounded on a simple idea. Having received a mandate from the people, the legislative chambers should have the possibility to check how the State manages public affairs. This will help the State continue going on the right way, which most corresponds to the desires of the national community.However, in the Democratic Republic of the Congo, political actors who take part in this process (control) have totally distorted or denatured it for unveiled reasons. We consider this distortion or denaturation of the parliament members’ role as political « vicissitudes ». This article is meant to display the various ways in which the parliament’s role is denatured in the Democratic Republic of the Congo. It has the merit to reveal to the large public the new and hidden side of the members of parliament mission as they control the government’s actions. Instead of ensuring transparency and efficiency in the State management, this parliamentary prerogative is surprisingly turned into a mean means for getting more wealth and hold on power.
