Constitutionality analysis of amendments to the Protocol on Environmental Protection on the Antarctic Treaty Annexes.

Antarctic environmental and climatic conditions have repercussions in Brazil and South America and are a central focus of concern as their balance may be affected. Therefore, legal instruments of environmental protection such as the Protocol on Environmental Protection to the Antarctic Treaty are fundamental. To streamline its application, the Protocol foresees accelerated mechanism for the approval and entry into force of "Measures" that modify provisions in its Annexes. This basis makes it unnecessary to submit amendments to domestic processes of international treaties approval in member countries of the Antarctic Treaty - in the case of Brazil, National Congress approval. This could give rise to a violation of Articles 49, item I, and 84, item VIII, of the 1988 Brazilian Constitution. This paper claims that there is no violation. This conclusion was based on an approach that supports constitutionality based on formal foundations and interpretation of the law, so that, mainly, the provisions and norms arising therefrom are understood in the context of Executive Agreements. The methodological construction is supported by the deductive method and assumes that the research hypothesis is controlled.
