See the article on the Bricker Amendment for the history of the relationship between the powers of the Treaty and the constitutional provisions. The Constitution does not have a supremacy clause with the same effects as those of the U.S. Constitution, which interests the debate on the relationship between treaties and the laws of the states of Brazil. On December 10, 2019, the First Victorian People`s Assembly met for the first time in the House of Lords of victoria Parliament in Melbourne. The main objective of the Assembly is to develop the rules under which individual agreements are negotiated between the Victorian government and some Victorian Aborigines. It will also establish an independent contractual authority to oversee and ensure fair negotiations between Aboriginal groups and the Victorian government.  The language of treaties, such as that of a law or contract, must be interpreted if the text does not appear clear or if it is not immediately clear how it should be applied in a perhaps unforeseen circumstance. The Vienna Convention stipulates that treaties must be interpreted in “good faith” according to “the ordinary meaning given to the contractual terms in context and in light of their purpose and purpose.” International legal experts also often invoke the “principle of the greatest possible effectiveness,” which interprets the language of the treaty so that it has the maximum strength and effectiveness in defining obligations between the parties. A party may require that a contract be terminated, even without any explicit provision, if the circumstances have fundamentally changed. Such an amendment is sufficient when it is unforeseen, undermines the “essential basis” of a party`s agreement, radically alters the scope of commitments between the parties, and the commitments have yet to be fulfilled.

After 1871, the federal government continued to maintain similar contractual relations with Indian tribes through agreements, statutes and executive ordinances.  The separation between the two is often unclear and is often politicized in disagreements within a government over a treaty, as a contract cannot be implemented without the correct modification of national legislation. When a treaty requires laws of application, a state may be late in its obligations if its legislator does not pass the necessary national laws.
