‘God willing,I will be back’: Gauging the Truth and Reconciliation Commission's capacity to deter economic crimes in Liberia

Recently, in July 2012, the high-profile and bitterly fought nine-month race for the post of Chair of the African Union (AU) Commission, between Dr Jean Ping of Gabon, and his main challenger, Dr Nkosazana Dlamini-Zuma, culminated in the latter's victory. Her victory came after the deadlock at the Eighteenth AU Summit in January 2012. Borne out of the considered need for a quick fix through reliance on a vote of expediency, the election of Dr Dlamini-Zuma represented a political resolution to the crisis that arose due to the earlier ongoing electoral deadlock. Far from being a competitive election by design, the 2012 AU Commission election by default became transformed into an intensely fought campaign that put the AU in the limelight. This article briefly introduces the electoral process, explains in detail the voting behaviour of AU member states, and offers five specific reasons for the victory of Dr Dlamini-Zuma. On the surface the election looks very competitive, but the article explains why this is not the case. To create greater competition for these posts, the AU needs to overhaul the nomination process and the voting procedure. In this regard, the article proffers detailed analysis and proposes a radical revision of the existing criteria for the nomination. The article also proposes specific recommendations for the amendment of the rules of procedure of the AU Assembly to allow for a qualified majority as a deadlock breaker in the fifth round. It also assesses whether the integrity of the AU Commission election was damaged during the campaigning and voting process. In this regard, it recommends the development of a code of conduct for future elections at the AU.     

THE AU MISSION IN BURUNDI

Abstract

Even though the Movimento Popular de Libertação de Angola (Popular Movement for the Liberation of Angola, MPLA) managed to take firm control of the state as the war ended in 2002, this article contends that its hegemony is not absolute. At the fringes of the state administration, emerging regional elites have established associations that seek to provide a remedy against the centralised system, which essentially deprives regions of political influence and sufficient economic resources. As in many other countries on the African continent, political identities that were legally enforced and institutionally reproduced in colonial times have hardly been transcended in the post-colonial period. Even if the associations' influence today does not yet reach further than bringing some insecurity to an otherwise secure polity dominated by the MPLA, the associations could play a role in reinforcing strong regional solidarity and give political expression to feelings of exclusion. Such sentiments could in turn lead to an increase of exclusivity ideas about citizenship, or even xenophobic violence. Much will depend on the strategies of the MPLA, and to what extent it will accommodate these emergent forces in the post-war era, not the least through the current sub-national state reforms.
