I want to know the answer to the following question:
The hierarchical position of treaties relative to domestic legislation in Brazil determines whether the latter can do what to the former and vice versa?
All the background I'm provided with is that "The hierarchical position of treaties in relation to domestic legislation is of relevance to the discussion on whether (and how) the latter can abrogate the former and vice versa.". Is that enough to answer the question?
Answer: yes
