I want to know the answer to the following question:
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?
All the background I'm provided with is that "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.". Is that enough to answer the question?
