Task: Question Generation
Input (English): The Federal Supreme Court has established that treaties are subject to constitutional review and enjoy the same hierarchical position as ordinary legislation (leis ordinárias, or "ordinary laws", in Portuguese). A more recent ruling by the Supreme Court in 2008 has altered that scheme somewhat, by stating that treaties containing human rights provisions enjoy a status above that of ordinary legislation, though they remain beneath the constitution itself. Additionally, as per the 45th amendment to the constitution, human rights treaties which are approved by Congress by means of a special procedure enjoy the same hierarchical position as a constitutional amendment. 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.
Output (English): What amendment to the Brazilian constitution states that human rights treaties approved by means of a special procedure by Congress enjoy the same position as a constitutional amendment?
