I want to know the answer to the following question:
In order for a treaty to be valid in Brazil, a presidential decree incorporating the treaty into domestic law must be published where in order to be valid?
All the background I'm provided with is that "Additionally, the Federal Supreme Court has ruled that, following ratification and entry into force, a treaty must be incorporated into domestic law by means of a presidential decree published in the federal register in order to be valid in Brazil and applicable by the Brazilian authorities.". Is that enough to answer the question?
Answer: yes
