Such phenomenon is present- ed as a common feature in the two constitu- tions of the nineteenth century – 1824 and 1891 – as well as in the five from the twen- tieth century – those of 1934, 1937, 1946, 1967 and 1988. On the one hand, there is a continuous line connecting constitutional texts, on the other hand, the absence of an exhaustive and clear description of the way in which the norms of international order would be received are quite salient. The existence of this gap has resulted, throughout the Brazilian constitutional experience, due to a growing presence of political constraints that, in turn, have led to the insertion and application of inter- national postulates in the domestic legal sphere. These constraints were material- ised through frequent overlapping of Ex- ecutive acts in relation to the other powers, unbalancing the then desired separation of constituted powers. In this context, the aim of this article is to analyse how the normative instruments and doctrinal discourses at the internation- al and constitutional levels were built in the nearly two hundred years of history of the national legal system.
