"Even though Article IV of the Constitution says that treaties are the 'supreme law of the land,' in most instances they're not even law"

This quote by Sonia Sotomayor is describing the truth that, even though the Constitution states that treaties are the greatest type of law, they are not always dealt with as such. This is since treaties are not always enforced or followed by the government or individuals. This is because of the truth that treaties are often hard to implement and need the cooperation of multiple parties. Furthermore, treaties are frequently viewed as a form of global law, which is not always appreciated or followed by domestic federal governments. This quote is a pointer that, although treaties are lawfully binding, they are not constantly dealt with as such.
