Duhamel has developed the approach further: He stresses that the French construction does not correspond to either parliamentary or the presidential form of government, and then develops the distinction of 'système politique' and 'régime constitutionnel'. While the former comprises the exercise of power that results from the dominant institutional practice, the latter is the totality of the rules for the dominant institutional practice of the power. In this way, France appears as 'presidentialist system' endowed with a 'semi-presidential regime' (1983: 587). By this standard he recognizes Duverger's pléiade as semi-presidential regimes, as well as Poland, Romania, Bulgaria and Lithuania (1993: 87).

A pattern similar to the French case of compatible majorities alternating with periods of cohabitation emerged in Lithuania, where Talat-Kelpsa (2001) notes that the ability of the Lithuanian president to influence government formation and policy declined abruptly when he lost the sympathetic majority in parliament.
