Tendenze e prospettive del monocameralismo negli ordinamenti democratici

Over the last few decades, the single-chamber parliamentary model seems to emerge in several democratic states as a trend in contemporary constitutionalism. A comparative survey of the salient features of unicameralism allows to assess reform proposals aimed at the transition from a pre-existing bicameral system to a unicameral system. In today’s pluralist democracies, such a reform needs an in-depth analysis of the implications of the choice regarding the fundamental parliamentary structure, its main functions and its ‘renewed’ representative vocation. In addition, a comparative analysis helps to identify the necessary correctives to prevent the predominance of the parliamentary majority in the single Chamber and safeguard the vital interests of minorities. Such a risk is aggravated by the growing cultural inhomogeneity of contemporary societies. In any democratic experience, the abandon of a bicameral model must take place in the awareness that Parliament, especially if unicameral, is called upon to give adequate institutional expression to the intercultural dimension of society
