The LRQ lies at the foundation of the constitutional tradition, as the struggle among powerful estates to assert privileges and franchises in the pre-statist medieval environment. Constitutional deals are continuously redefined, with the crown as one among several contracting partners. The LLQ concerns the administration of justice as the private sphere of individual freedom. Courts are the principal institution to guarantee the proper working of this basic constitutional pillar. The ULQ is a distinctive accomplishment of XIX century constitutions, with the state authority concentrated in the legislative assembly and with individual rights representing the constitution’s core element. The URQ reflects the contemporary collectivistic trend towards constitutional charters incorporating wider social demands and values. Thus transforming constitutional law into a dynamic arena for the more or less effective implementation of a vast array of norms.
