Shugart, Matthew Søberg (decembro de 2005): "Semi-Presidential Systems: Dual Executive AndMixed Authority Patterns"French Politics3: (323–351). Consultada o 4 de agosto de 2016. (cita: "Of the contemporary cases, only four provide the assembly majority an unrestricted right to vote no confidence, and of these, only two allow the president unrestricted authority to appoint the prime minister. These two, Mozambique and Namibia, as well as the Weimar Republic, thus resemble most closely the structure of authority depicted in the right panel of Figure 3, whereby the dual accountability of the cabinet to both the president and the assembly is maximized. (...) Namibia allows the president to dissolve [the assembly] at any time but places a novel negative incentive on his exercise of the right: He must stand for a new election at the same time as the new assembly elections."
